Meet Innventia at PaperCon 2015Innventia will attend PaperCon 2015 in Atlanta, 19-22 April. The booth 332 will be a meeting place for discussions on future papermaking.

PaperCon brings together CEOs, mill managers, superintendents, scientists, process engineers and suppliers for the largest pulp and paper technical programme in the world.

Last year, Innventia participiated both in the conference part and in the exhibition part.

“The booth provided an opportunity to continue the discussion on topics in the scientific seminar programme,” says Fredrik Rosén, Director Market Strategy at Innventia. “It was also nice to have a spot just to meet friends and business colleagues.”

This year PaperCon is celebrating 100 years and the event is bigger than

ever. So is Innventia’s representation at PaperCon.

“We will give a variety of presentations on subjects such fractionation, mixing, stratified forming, SC paper, functional materials and material identity,” Fredrik explains.

One of the contributions is a paper written in cooperation with the Swedish company Acosense on their new measuring method and the results of the trial carried out at Innventia in 2014 (see page 3). Another presentation is about the Innventia Global Outlook Papermaking Towards the Future which was released just before last year’s PaperCon. Fredrik is, however, convinced that the report is just as relevant today.

“We look forward to meet the delegates at our booth 332 for inspiring discussions on future opportunities.”

Svenska Acosense har med hjälp av försök i Innventias pilotanläggning kunnat visa att företagets mätinstrument även kan användas för att analysera fibrer i massa. Försöken gjordes i mäldberedningen vid Innventias pilotanläggning för papperstillverkning, FEX. Här fick Acosense fick möjlighet att testa sin metod i ett projekt med en papperstillverkare som skulle göra tester på massa. Med hjälp av hydrocykloner delades massan upp i två strömmar för att skapa variationer. Koncentration och egenskaper mättes med en etablerad mätutrustning för att få en referens till det ljudspektra som uppmättes med Acosense instrument. Resultaten stämde väl överens. Idag samarbetar företaget med papperstillverkaren och Innventia för att hitta nya tillämpningar för analysmetoden.

FRACTIONATION USING HYDROCYCLONES

In advanced stock preparation, fractions with homogeneous fibre properties are frequently required. The aim is often to obtain a production process that makes effective use of both energy and raw materials. Another objective may be to produce paper products with specially designed properties.

One technique that can be used to obtain a stock with homogeneous fibre content is fractio-nation using hydrocyclones. The fibre suspension is then added to a rotating flow, and the cyclones separate the fibres according to properties that affect their ability to bind, such as wall thickness, flexibility and fibrillation.

RISE Test beds and DemonstratorsRISE Research Institutes of Sweden’s cross-sectorial Test Beds and Demonstrators project was carried out 2013-2014.

This Vinnova-funded project aimed to give more players – primarily small and medium-sized enterprises (SMEs) and universities – access to test beds such as Innventia’s FEX pilot paper machine. On the following pages we will report on three examples of research and development enabled by the RISE Test Beds and Demonstrators project.

A new two-year period of the project was launched in February, 2015. This second phase aims to further develop and implement the findings from phase 1.

Swedish company Acosense has used tests carried out at Innventia’s pilot facility to demonstrate that its measuring instrument can be used for a new application: analysing fibres in pulp. At the same time, they also made contact with a new customer.

Instrument manufacturer Acosense has developed a unique new method for contactless analysis of fluids. The tech-nology has already been used for several years to measure the moisture content of black liquor.

When the company came into contact with Innventia, the idea arose of testing whether the method could also be used to analyse fibre properties in pulp.

At that time, there turned out to be a paper manufacturer at Innventia who wanted to carry out tests on pulp. Acosense had the opportunity to test its method within their project. The method is based on an instru-ment (Acospector) with software that is adapted according to the process to be measured. The instrument is clipped to the pipe containing the fluid that will be analysed. The actual analysis is then carried out using an acoustic signal. The signal, which is produced by a shaker, is affected by the properties of the fluid. It is recorded and processed by software, and the results provide data on proper-ties such as particle size, viscosity or moisture content.

“This seemed like an exciting new measuring instrument,” says Annika Bjärestrand, a project manager at Innventia.

Pulp trials were carried out in the stock preparation system at Innventia’s pilot papermaking facility, FEX.

“In order to test the measuring instru-ment, we wanted to create differences in the pulp received from the paper manu-facturer,” she explains. “We did this by dividing up the pulp into two streams using hydrocyclones in the FEX facility. These are used, for example, to remove sand and bark particles from the pulp that could interfere with the process. They can also be used to fractionate the fibre and distinguish between fibres with different properties. This gave us two streams with variations in fibre concen-tration and fibre properties, primarily in their fine material content.”

Pulp concentration, fibre length and fine material content were measured using established measuring equipment to give a reference for the acoustic spec-tra measured with Acosense’s instru-ment. Readings were obtained from the acoustic spectra, and these were com-pared with the reference. The results were very similar.

“The trial shows that Acosense’s acoustic measurement gives a good pic-ture of the process. Readings can be obtained in real time for concentra-tion, fibre properties, etcetera, and we can monitor the process and see if it changes.”

Acosense is a small company with just five employees. Small and medium-sized companies such as Acosense can find it hard to afford to carry out this type of research on their own, and there are too few of them to have the necessary breadth of expertise.

They now had the opportunity to finance the trial through RISE Research Institutes of Sweden’s Test Beds and

Demonstrators project, which aims to give more players access to test beds such as Innventia’s FEX pilot machine.

Marco Lucisano, a research manager at Innventia, highlights the opportunity to link these small companies together with other customers.

“In this case, Acosense had the chance to test its method within a relevant project, with a large paper manufac-turer that was also carrying out trials at Innventia.”

This turned out particularly well for Acosense. The company is now working together with the paper manufacturer and Innventia to identify new applica-tions for the analysis method.


There are currently all manner of exciting developments going on within papermaking. Both the industry and the world around us face dramatic changes – an evolution towards a bioeconomy in which more and more materials can be replaced with forest products. Innventia Paper Blog will keep you updated on current activities and discuss future possibilities.

Think ahead – that’s one of Innventia’s mottoes. But we also want to think new and think together. Of course, this is par-ticularly important when facing major changes, as is currently the case.

Paper has been part of our everyday lives for centuries. It has mostly been used for printing, tissues and packaging, but also for many other uses. The past 20 years have seen a drop in demand for printing and writing paper, but there has been an increase within other types of paper and pulp production. Packaging, labels and lining are just a few examples of growth areas.

As a society, we need to work togeth-er in these areas across industry bounda-ries. We need to ensure that we have knowledge for the future, and we need to prepare for different scenarios.

Innventia is launching a new paper-making blog as part of this effort, Innventia Paper Blog.

“Here on our blog, we’ll tell you about the latest news, studies and results”, says Marco Lucisano, who coordinates Innventia’s activities on Papermaking.

According to him, the blog will also discuss Innventia’s latest Global Outlook report: Papermaking Towards the Future and also introduce some of the people involved – researchers and other key individuals who are dedicated to meet-ing the challenges of the future with their ideas and actions.

“Join us as we create the future of papermaking. Let us tell you what’s on our minds. And don’t hesitate to tell us what’s on yours. We’re all ears!”

Inom forskning och utveckling krävs ofta pilotstudier för att visa att en idé som fungerar på labb också gör det i större skala. Vid pilotpappersmaskinen FEX kan forskare göra detta. Maskinen liknar de som finns i industrin. En av de forskare som använt Innventias pilotmaskin för att undersöka en delprocess som redan studerats i labb är Björn Sjöstrand vid Karlstads universitet. Hans forskning handlar om avvattning, och han ville undersöka hur stor återvätningen i papperet är och med vilken hastighet den sker. Tillsammans med Innventias personal kunde han planera pilotkörningen och få tips om olika metoder, t.ex. för att ta prover och variera luftflödet. Resultaten av försöken blev en bekräftelse på att han var på rätt väg. Han kunde visa såväl hur stor återvätningen var, som hur snabbt den gick.

Researchers can use the FEX pilot paper machine to test and develop theories on a larger scale than in the lab, or to demonstrate that a concept actually works. The machine is similar to those found in industry.

The paper machine enables test runs to be carried out under conditions simi-lar to those found in industry. Smaller machines often lack the peripheral equipment present in paper mills, such as closed systems in which the process water can recirculate.

“This means that researchers are unable to study some other part of the process,” says Marco Lucisano, a research manager at Innventia. “The parts that are lacking may be relevant to the results.”

Pilot studies are often needed in research and development to demon-strate that an idea that works in the lab will also work on a larger scale. One of the researchers who has used Innventia’s pilot machine to investigate a sub-pro-cess that had already been studied in the lab is Karlstad University’s Björn Sjöstrand. His research examines the dewatering process, in which water is sucked out and led away from the sheet as it makes its way through the paper machine.

Some of the water that is sucked out returns to the paper. Björn wanted to investigate the extent and speed of this rewetting.

“We were able to plan the pilot run and suggest different methods for tak-ing samples and varying the airflow, for example,” explains Hannes Vomhoff, a research manager at Innventia who car-ried out a run within the same area a few years ago.

“The measuring technique developed in that run was suitable for reuse in Björn’s test.”

Dewatering is a fairly inefficient and energy-intensive part of the papermak-ing process, and a great deal of research and development is being carried out within both academia and industry to improve its efficiency, speed and energy consumption. For example, this could involve modifying the fibres to make dewatering easier without compromising on the properties of the end-product.

Another example that is continu-ously being addressed within industry is adjusting the wire on which the sheet lies in order to increase dewatering. The air can only flow through and suck out the water where there are openings. One way of getting the sheet to dry more quickly would therefore be to design the underlying wire to increase the through-flow of air.

Innventia has developed an analy-sis method for use in this work that makes it possible to quantify the drying speed locally. This is an example of the dewatering research being carried out at the research institute. Another research project involves controlling the process to ensure even dewatering.

“We have excellent research condi-tions with the pilot environment, unique

lab equipment and advanced measuring techniques,” continues Hannes.

The results of the pilot machine run confirmed that Björn was on the right track. He was able to show both the extent and the speed of the rewetting. However, rewetting does not always occur. One of his long-term aims is therefore to be able to explain when this occurs and why.

The trial runs have been financed by RISE Research Institutes of Sweden’s Test Beds and Demonstrators project, which aims to give more access to test beds such as the FEX pilot machine.

Företaget Vasasensor har tagit fram ett instrument som dynamiskt mäter pressnyp, Press Eyes. Instrumentet har sensorer som monteras på ett klisterark och fästs på pressvalsar och transportbälte. I pressen mäter sensorerna nypet och skickar trådlöst mätdata till mottagaren som monteras nära valsen. Företaget hade genomfört framgångsrika tester i labb och för att testa det dynamiska förloppet med full last och hastighet gjordes försök på Innventias pilotpappersmaskin FEX. Här kunde de verifiera att instrumentet fungerar under verkliga förhållanden. Två försöksomgångar genomfördes för att hitta rätt klister och testa olika mottagare samt mäta pressnyp under olika förhållanden. Under våren väntar mätningar på två pappersbruk.

Vasasensor previously developed a measurement system, Press Eyes, that dynamically measures press nip. They have now produced a new version. In trials using Innventia’s pilot paper machine, they have verified that the system works under real conditions. Measurements will now be carried out at two paper mills during the spring.

Water is squeezed from the sheet of paper in the press section of the paper machine. It is important that the water is pressed out as evenly as possible. Otherwise, this can result in a sheet with uneven quality after drying.

Measuring the press nip shows how even the pressing is. The classic – and simplest – measuring method involves laying pressure-sensitive paper between rollers or shoes in the press section. This gives a pattern showing how even the nip is, but only when the machine is not running. The new system, Press Eyes, uses sensors and receivers to give dynamic measurements. The second ver-sion, version 2.0, features a new receiver model with more advanced electronics. The sensors are mounted on an adhesive sheet and attached to press rolls and transfer belts. In the press, the sensors measure the nip and send measuring data wirelessly to the receiver mounted close to the roll.

“We’d tested things like signal strength and transfer effectiveness in the lab,” explains Erika Jabler, an application engineer at MLT, which is licensed to develop and sell the instrument. “But the dynamic sequence with full load and speed can only be tested in full-scale paper machines or pilot machines.”

The company therefore carried out a number of trials using Innventia’s FEX pilot paper machine. The trials were

financed through the RISE Test Beds and Demonstrators project (see page 2). Over the course of two days, they tested the different receivers and measured the press nip at different speeds and differ-ent loads on the presses.

The equipment was tested during two rounds of trials in the pilot machine. The first round involved finding the best adhesive for attaching the sheet with the sensors to the rolls. In the second round, they tested the different receivers and measured the press nip under different conditions. To test where the receivers – which are smaller than in the previous version – should be mounted, Innventia employees built holders for these in the pilot machine.

“Every trial using FEX is carried out in collaboration with the customer to some extent,” explains Innventia’s Catherine Östlund, who project man-aged the trials. “In this case, the custom-er was extremely knowledgeable. We measured the holders, built and mount-

ed them, helped to plan the running schedule with speeds and press loads, and of course were involved in running the trials in the machine. Sometimes the customer may need more help planning the trial, in which case we can also help with that.”

“The measurements worked well, and we got the results we expected,” con-cludes Erika. “We measured both con-ventional roll press and shoe press nips, and were able to verify the differences. We also compared the old system with the new one, and noted that the new system gave us a higher resolution.”

MLT will carry out two measure-ments at paper mills using the new sys-tem during the spring.


Over the course of two days, Vasasensor tested different receivers and measured the press nip at different speeds and different loads on the presses. To test where the receivers should be mounted, Innventia employees built holders for these in the pilot machine FEX.

People coming to Innventia often gaze at the size of the papermachine FEX and the fact that there is a paper mill in the middle of Stockholm. FEX is, however, the smallest possible instrument for studying the papermaking process under realistic conditions. A facility needs to be able to work for smaller volumes. Access to materials during a trial should not need to be the same as in full-scale production. For example, industrial paper machines are often more than five metres wide in industry, whereas a narrower paper web can be enough in a trial. It just has to perform under authentic conditions in all other respects.

“We were able to verify that we had succeeded in doing what we thought we had managed to do,” she continues. “We can see the same things as before, but we can now get even more information in real time. We’ve also saved a lot of data that we can analyse and use later on,” says Erika Jabler.




Det franska mineralföretaget Imerys vände sig till Innventia för att kunna testa en metod för att höja halten fyllmedel (mineral) i papper. Mineral är billigt jämfört med fibrer och kan man öka kvoten blir tillverkningen billigare. Problemet är att papperet får sämre styrka om man enbart tillsätter mer mineral. Imerys har löst detta genom att blanda mineral med nanocellulosa som dock kan ge problem med avvattning. För att testa metoden gjordes pilotförsök på FEX. Resultaten visade tydligt att det går att behålla retention och styrka med ökad halt fyllmedel, om det också finns inblandning av nanocellulosa i fyllmedlet. De visade också att avvattningen inte var något problem. Företaget kan med hjälp av pilotförsöken visa vad som förväntas hända i pappersmaskinen hos en presumtiv kund. Resultaten har visat sig stämma bra överens med vad som händer i fullskala.

Medicinteknikföretaget Magle kontaktade Innventia för ca sju år sedan och ville ha hjälp att vidareutveckla sitt Phadebas Forensic Press Test, ett filterpapper med beläggning som används inom kriminaltekniken. På Innventia tog vi fram en kontinuerlig metod för tillverkning på en löpande bana i en av våra pilotanläggningar. Sedan dess kommer de tillbaka varje år för att under några intensiva dagar stärkelsebelägga ett helt års produktion. Det är alltid speciellt när de kommer. Innan produktionsveckan monteras sprayutrustning och torkcylinder på Linda. Hela maskinen plastas in och desinfekteras med laboratoriesprit, även och golv och arbetsytor behandlas med bakteriedödande medel.

Many large companies carry out trials using Innventia’s FEX pilot paper machine. These trials are tailored to be as close to industrial conditions as possible. For example, the international mineral company Imerys was able to test a method it had developed for increasing filler content in paper.

Both researchers and small and medium-sized companies carry out pilot testing using Innventia’s pilot paper machine. This often involves testing a brand new idea or a product that will be devel-oped. Sometimes a sub-process will be studied, such as dewatering or adding chemicals. When a customer approaches Innventia, they are offered suggestions for what can be done in the pilot facility.

“We discuss what the customer wants to do, and the aim of the trial,” says Lennart Hermansson, a process technol-ogy specialist who has worked at the paper machine since 1982. “Changes sometimes need to be made in order to run a particular trial.”

The trial that will be carried out is then tailored to be as close to industrial conditions as possible. If the customer is a large company, it will often have broad expertise and good knowledge of the process.

“What we then discuss is the trial and the adaptations that need to be made in order to work in our pilot environment.”

One such customer is the French min-eral company Imerys, which contacted Innventia to test a method for increasing

filler content (mineral) in paper. Mineral is cheap compared with fibres. If the mineral content can be increased, the manufacturing cost comes down. The problem is that the paper loses strength when only adding more mineral. Imerys has solved this by mixing mineral with nanocellulose. However, nanocellulose can lead to problems with dewatering. They therefore wanted to test the meth-od in a paper machine on a pilot scale.

“This is an extremely competent cli-ent who knows chemistry. And we know the machine.”

In a typical pilot study the paper machine is run while staff from Innventia carry out measurements, monitor the process and hold discussions with the customer during the run. Adjustments can be made during the process if neces-sary, such as changing the headbox flow or the chemical levels.

“We can let an attempt go haywire. Limits and extremes conditions should be tested in a pilot machine. They’re sometimes even essential when testing a new product, technique or chemicals, for example, in order to get an idea of where the boundaries lie.”

Sometimes – as in Imerys’ case – there are strict confidentiality requirements. The company has developed its own method for manufacturing the nanocel-lulose that is mixed with mineral, and didn’t want this knowledge to reach its competitors. At the same time, they were reliant on external help to carry out testing on a pilot scale. The company therefore contacted Innventia, as they had previously had good experiences from trials using the pilot machine.

A confidentiality agreement was drawn up, and the trial could then begin. Imerys had prepared a number of dif-ferent products with ready-made secret mixtures of nanocellulose and filler. These were tested within the process in the pilot paper machine. Innventia meas-ured dewatering, retention and initial wet strength. After drying, the paper was shipped to Imerys’ own lab for fur-ther tests.

Experts from Innventia and exter-nal parties were involved in discussions about the chemistry, including which retention system should be used. A special headbox was chosen in order to optimise the process. The opportunity was also taken to test different pres-sure levels, as this affects strength. The process water circulates within a closed system, just like in an industrial process.

“Recirculating process waters is incredibly important for this type of trial. Otherwise, you can’t make comparisons with what happens in an industrial paper machine,” says Lennart Hermansson.

The results clearly showed that it is possible to maintain retention levels and strength with increased filler content if nanocellulose is mixed into the filler. They also showed that dewatering was not a problem. Imerys’ Per Svending explains that the company has benefited greatly from the trial.

“Every time we’ve held discussions with a prospective customer for a trial run, we’ve shown the results to demon-strate what we expect to happen in the paper machine. This gives us credibility and has also been shown to correspond closely with what happens on a full scale.”


On our mind

Ahead of the production week, spray-ing equipment and drying cylinders are mounted onto LINDA.

Anyone who has worked at Innventia for a few years knows straight away when a new production run is under way. The entire machine is covered in plastic and disinfected using laboratory spirit – you can almost pick up the hospital smell as you approach the production premises. Everything is cleaned thoroughly, and the floors and work surfaces are treated with an anti-bacterial agent. Of course,

our labs are always clean and tidy, but when we work with

Magle things have to be taken to a whole new

level! For instance, we rarely wear hair-nets and face masks at other times.

A production day begins with dis-solving a batch of starch, which takes around 30 minutes. The solution is then held in a vessel, where it is stirred, and the vessel is connected to the spray rig. A roll of special filter paper is affixed to LINDA, the web is set rolling, the spray rig is started up and production begins. Several kilometres of paper are coated with starch during a production run, which is why an even, reliable process is so important.

Magle are always present throughout production, and we work together at

Around seven years ago, a Swedish med-ical technology company called Magle contacted Innventia, asking for help to develop a product. The product, which is now sold under the name Phadebas Forensic Press Test, is a specialist paper with a starch-coated surface that reacts when it comes into contact with sali-va. As the name suggests, this is used in forensic investigations. The paper is pressed against an object that is suspect-ed to have traces of saliva on it. If saliva is indeed present – even in very small quantities – the starch reacts and investiga-tors can tell where to take samples for DNA analysis.

Prior to development at Innventia, the starch was sold as a powder that was dissolved at forensic laboratories and sprayed onto filter paper. The results varied significantly, depending on who carried out the test and how. Here at Innventia, we devised a continuous pro-duction method using a running web in one of our pilot facilities called LINDA. The starch-coated paper is then ready for immediate use, and the quality is extremely high and even.

When working with Magle, we can coat an entire year’s production of Phadebas Forensic Press Test with starch over the course of just a few busy days.

In December, Magle visited again for a new production round of their Phadebas Forensic Press Test, a coated filter paper used in forensic investigations. We always look forward to Magle’s visits. At Innventia, we mostly deal with thinking about and developing the products and processes of the future. But in this case, we’re actually involved in the production process itself.

Meet Innventia at PaperCon 2015Innventia will attend PaperCon 2015 in Atlanta, 19-22 April. The booth 332 will be a meeting place for discussions on future papermaking.

PaperCon brings together CEOs, mill managers, superintendents, scientists, process engineers and suppliers for the largest pulp and paper technical programme in the world.

Last year, Innventia participiated both in the conference part and in the exhibition part.

“The booth provided an opportunity to continue the discussion on topics in the scientific seminar programme,” says Fredrik Rosén, Director Market Strategy at Innventia. “It was also nice to have a spot just to meet friends and business colleagues.”

This year PaperCon is celebrating 100 years and the event is bigger than

“We will give a variety of presentations on subjects such fractionation, mixing, stratified forming, SC paper, functional materials and material identity,” Fredrik explains.

One of the contributions is a paper written in cooperation with the Swedish company Acosense on their new measuring method and the results of the trial carried out at Innventia in 2014 (see page 3). Another presentation is about the Innventia Global Outlook Papermaking Towards the Future which was released just before last year’s PaperCon. Fredrik is, however, convinced that the report is just as relevant today.
