DESCRIPTION OF OPERATIONS1

Mobilization. Equipment set up, energy/steam supply arrangements in accordance with po-tentially hazardous zones regulations. Depending on the tank’s diameter the required number of nozzles installed via the roof - 5 daysSteaming. Steam is supplied through tank cleaning nozzles directly into sludge. Steaming process continues until all sludge has been liquefied and separated into three fractions: oil, water and solid sediments. Operators constantly manage speed of steam supply and storage tanks' surface temperature (+/- 55C°). Exact duration of steaming depends on sludge quantity and composition - 14 daysHydrocarbons (HC) Recovery: HC are pumped directly to the pipeline or holding tank – 5 days2

Condensate drain: water is drained into the sewage or the same tank. No special water treatment is required and it can be treated internally - 2 daysVentilation: After the water drain, manholes should be opened to vent the tank. Once the tank atmosphere has been approved by a safety manager, personnel are admitted to enter. Final Cleaning: At this stage no sludge left in the tank, only a layer of oil-contaminated solid sediments on the bottom. Roof, shell (coating) and legs are clean ideally and oil-free. Approxi-mate quantity of sediments is 50-150 m3 in large tanks with capacity more than 50,000 m3 - 15-20 days Total for large storage tanks: around 40-50 days RESULT: TANK IS READY FOR MAINTENANCE AND HOT WORKS.

NN QUESTION ANSWER

1 Do you use any chemical solutions in the cleaning?No. It helps to keep the technology green and environmentally friendly. Moreover, it helps to avoid any damage to pipelines and/or other facilities

2 Why do you claim your technology can help in fixingdamaged tanks?

The system does not require any staff presence inside the tank during cleaning and recovery stages. The process is safe and explosion-proof

3Can the recovered oil be pumped into existing tankwhich is in service, or it must be pumped into anotherholding tank? This is during the sludge recovery period.

There is no restrictions to deliver oil into an operating tank. There is no need to isolate a tank and treat it as a holding one. Recovered HC can be delivered to another crude tank which is operating 24 hours per day (during day and night shifts)

4 What is the category of steam required? MP4? could youplease explain what MP4 means?

Steam parameters: quantity 2-5 t/hr (depends on tank's storage capacity), temp.+150C°

5 Does ARKOIL tank cleaning technology require to drillnew holes on top of tank roof, or you can use existing holes?

No, the system does not require to do this. This is one of the advantages of the technology to avoid damage to the shell or roof

6How are the oil and water layers drained after being separated? Is there any need to weld new eruptions in the tank shell?

New eruptions are not required as water and oil are pumped out from the existing sump/water drain-off or side manhole of the tank.

The solid sediments are removed manually but the quantity of these sediments is minor (around 50-150 m3).


How is the last part of solid sediments being removed?7

FAQ

NN QUESTION ANSWER

8

What is the indoor temperature at steaming stage? We are concerned that the required steam temperature at +150C° will disintegrate the primary seals of the floating roof, which have the maximum temperature of +90C°

The temperature at the level of seals reaches +60C°- 70C°

9

The ambient temperature in our region is higher (about +30C°) than the ambient temperature in The Netherlands (about +5 - 20C°). Will this cause more vapour to be emitted when the peripheral seals are opened for insertion of the tank cleaning nozzles by the engineer?

The vapour emission due to the opening of the seals for insertion of the tank cleaning nozzles is insignificant. We have positive experience of working in regions with air temperature around +50C°

10

We are concerned that the recovered product will contain water (condensed) and hydrocarbons mixture, and the presence of water will inflate the final recovered volume of hydrocarbons. Moreover, the transfer of the recovered emusification containing oil and water into a holding tank might reduce the quality of crude oil?

During the recovery stage only hydrocarbons are recovered (99.94%). Only at skimming stage there can be some unconsiderable volume of water in the mixture of hydrocarbons but even this can be excluded. The water left will never deteriorate crude oil in the holding tank. The process of recovery & skimming is being closely monitored by the client though constant sampling of the recovered product
