3 ARKOIL System Technology is based on transformation of steam energy and application of special tank cleaning nozzles More than (one thousand) of crude tanks have been cleaned by ARKOIL system ARKOIL System is developed to operate in potentially hazardous zones The System can be tailored to customers' any special needs and/or requirements Size of tanks can reach up to m 3, with fixed or floating roofs. The total amount of accumulated sludge is unlimited ARKOIL Technologies has a very considerable experience in cleaning of damaged tanks 3 ARKOIL Technologies Nederland B.V.

9 Work flows DESCRIPTION OF OPERATIONS 1 Mobilization. Equipment set up, energy/steam supply arrangements in accordance with potentially hazardous zones regulations. Depending on the tank s diameter the required number of nozzles installed via the roof - 5 days Steaming. 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 days Hydrocarbons (HC) Recovery: HC are pumped directly to the pipeline or holding tank 5 days 2 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 days Ventilation: 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. Approximate quantity of sediments is m 3 in large tanks with capacity more than 50,000 m days Total for large storage tanks: around days RESULT: TANK IS READY FOR MAINTENANCE AND HOT WORKS. MOBILIZATION STEAMING HC RECOVERY FINAL CLEANING 1 2 Example: m 3 crude oil tank with m 3 of oil sludge Depends on technical ability of a refinery/terminal to accept the recovered hydrocarbons 9 ARKOIL Technologies Nederland B.V.

13 FAQ 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 fixing damaged tanks? The system does not require any staff presence inside the tank during cleaning and recovery stages. The process is safe and explosion-proof 3 4 Can the recovered oil be pumped into existing tank which is in service, or it must be pumped into another holding tank? This is during the sludge recovery period. What is the category of steam required? MP4? could you please explain what MP4 means? 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) Steam parameters: quantity 2-5 t/hr (depends on tank's storage capacity), temp. +150C 5 Does ARKOIL tank cleaning technology require to drill No, the system does not require to do this. This is one of the advantages of the new holes on top of tank roof, or you can use existing holes? technology to avoid damage to the shell or roof 6 How 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. 7 How is the last part of solid sediments being removed? The solid sediments are removed manually but the quantity of these sediments is minor (around m 3 ). 13 ARKOIL Technologies Nederland B.V. Innovative tanks cleaning system

14 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 14 ARKOIL Technologies Nederland B.V. Innovative tanks cleaning system
