Cartridge FiltersApplications

Operating Principle

The cartridge filters are designed to remove all solidparticle contaminants such as dirt, rust pipeline scalefrom Natural Gas in Chemical Plants, PipelineStations, Reduction and Metering stations, Refineriesand other processing applications. Cartridge Filtersprotect meters, regulators, valves and other relatedin-line equipments, by effectively removing unwantedparticles from the Gas stream.

The cartridge filters are able to guarantee high effi-ciency standard by removing the solid contaminantsat relatively pressure drop. Upon entering the largerand heavier particles settle to the bottom of the inletchamber. And then the gas, by passing through the fil-ter elements which trap and retain the finer parti-cles, exits clean to the top of the vessel. It could beinserted a “quick opening” end closure for access to,cleaning or replacement of the filter elements.

Filtering Cartridge

TECNOFORGE Systems is able to provide engineered, designed, and manufactured, range of medias, to provide the reliability and consistencyin performance. This is necessary for the delivery of outstanding operating efficiency in a wide variety of filtration applications. TECNOFORGE Systemsexperienced Sales and Application Engineers can assist you in selecting thecorrect element to solve your particular filtration problem.

Efficiency

The efficiency of this kind of filteris a typical function of particlesize and distribution, particle loa-ding, element face velocity andpressure drop. A typical perfor-mance efficiency is 100% for par-ticles of 3 micron and larger and99% for particles between 0.5-3micron. On the left is shown atypical performance diagram.

Knock-Out Drum Vane Mist Extractor

Models - Production Range

Operating Principle

The extractor consists of a vanes pack formed by a series of parallel platescomplete with an intermediate series of hooks. The gas, flowing through thevanes, is forced to change direction several times and the heavier liquid droplets are then smashed against the wetted walls. The small particles arecoalesced by agitation and surface contact. The agglomerated liquid is thendrained perpendicular to the gas flow into the sump.

Efficiency

The efficiency of this kind of filter is a typical function of particle size and distribution, particle loading, elementface velocity and pressure drop. Thevane mist extractor is able to removeliquid droplets up to 8 microns and larger.

The cyclone separator is used in a wide range ofapplications in the natural gas and chemical processindustries such as:● Metering and reducing Stations: removing liquid

hydrocarbons, water and sand● Natural Gas field application● Gas and Fuel transmission lines● Meter Installations● Gas compressors

Efficiency

Operating principleThe operating principle of the cyclone filter separator is based on the action of centrifugal forcesthat separate the solid and liquid parts. The gas, entering into the cyclone, forces the particles against the cyclone walls moving the liquid dropletsand the solid particles to the outer periphery of thetube and then dropping them into the collectionchamber at the bottom of the vessel. The cleaned gasexits instead to the top of the vessel to the eventual second stage cartridge dry separator toremove the finest solid particles. The cyclone filterseparator could be designed with a single cycloneaction or with a multiple cyclones action in order toraise the efficiency of the process.

Dual-stage Filters

Operating principle

Filtering Cartridge

The absolute filter separator is designed to be installed in a vertical or in a horizontal configuration,it could be inserted a "quick opening" end closure foraccess to the filter elements. The gas enters the vesseland encounters a labyrinth of pipes that give a centrifugal motion to the particles of 10 micron andabove to the bottom of the filter. Smaller particleswhich exhibit significant brownian movement collidewith each other coalescing to a single droplet.Anelastic collision of solids produce then aggregateswhich subsequently are swept by the liquid into thesump. Particles that remain suspended encounter thefilter coalescer elements and then they collide withand adhere to the fibers or other droplets and coalesce. This agglomerated liquid is then forcedthrough the media by the drag of the gas for thesecond stage separation. The second stage section,which is the vane mist separator, by changing the direction of the vapour to generate an increase inapparent density of the liquid phase, trap all the liquiddroplets in the hooks draining the same into the sump.

The filtering elements are engineered, designed andmanufactured, in a variety of medias, to provide thereliability and consistency in performance. This isnecessary for the delivery of outstanding operatingefficiency in a wide variety of filtration applications.Our experienced Sales and Application Engineers canassist you in selecting the correct element to solveyour particular filtration problem.

ApplicationsThe absolute filter separator is a multi stage separator used in a variety of applications in thenatural gas and chemical process industries such as:

● Metering and reduction Stations: removing liquidhydrocarbons, water, sand and pipe scale.

● Ahead of gas storage fields to prevent the injectionor withdrawal of solids and liquids.

● On the suction side of the compressor to preventwear from solids and liquids entrained in the gasstream.

● On a gas processing plants to remove solid and free liquids in order to prevent fouling of processequipment and poisoning of catalyst beds.

● Downstream of amine, glycol, potassium, carbonatesulfinol and absorption oil contactors to recoversolutions and reduce solution losses.


Shell and tubesHeat ExchangerHeat exchangers are designed for heating naturalgas, air, propane and other non aggressive gases. Theyare designed to compensate the Joule-Thompsoneffect during a gas expansion, in order to avoid thehydrates formation potentially dangerous in gastreatment and reduction station. The working principle is based on heat exchange by conductionbetween the heating fluid (hot water or steam) andthe gas to be expanded. Heat exchangers guaranteea wide exchange surface in order to keep high thermal efficiency.

Gas Heater

What is an indirect HeaterAn indirect heater is an oilfield terminology for avessel complete with: a firetube (which is usuallyfired by natural gas), a fluid around the firetube(which is usually water) and, immersed in the fluid, a coil containing the fluid to be heated. The waterbath around the firetube is heated directly by havingcontact with the firetube and the coil containing thefluid to be heated is immersed in this hot water bath.Because there is an intermediate step of heat transfer between firetube and coil, the heater derivesits oilfield terminology of “indirect heater”.

Use of the indirect HeaterNormally the natural gas is produced at high pressures ranging from 1,500 psi up to 3,000 psi and it’s usually transferred to sale gas lines that operate at 1,200 psi and below. The indirect heater is often employed to supply heat to a gas stream that is being expanded from some elevated pressure(well head) to some intermediate pressure (intermediate production equipment) or to theactual sale line pressure. Heat supplied is used tocompensate for the Joule-Thompson effect of the gasthrough expansion.

Why an indirect HeaterIt is to be found in an economic justification. The fluid carrying coils are operated at a maximum pressure of 3,000 psi. (depending on the customerrequirements), whereas the shell of the indirect heater containing the heat transfer medium (water)is operated usually at atmospheric pressure, or at avery little pressure above it, therefore it’s required athin wall vessel for the heater shell. In addition, alsothe firetube needs withstand only the atmosphericpressure plus a few pounds. It would be prohibitivefrom several standpoints to attempt to make firetube to withstand the pressure of 3,000 psi aswell as the heater shell itself; thus the creation of theindirect type heater with fluid carrying high pressurecoils immersed in an atmospheric pressure waterbath heated by a firetube operating close to theatmospheric pressure.

High Performance and High Efficiency

The high pressure fluid is introduced to the heatingunit through a choke located at the heater inlet, andthe expansion takes place immediately inside theheater in the water bath. Then, as the fluid passesthrough the steel coils, it’s raised to the desired outlet temperature suitable to compensate theJoule-Thompson effect during the expansion. Thesteel coil, which is subject to the well head operatingpressure, is subject further to corrosion by the fluidcarried within the steel pipe as well as erosion caused by the high velocity of the fluid itself. In timethe combination of corrosion and erosion takes itstoll in wall thickness of steel pipe.
