DESCRIPTION OF OPERATIONS1
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 days2
MOBILIZATION
STEAMING
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 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.
Example: 100.000 m3 crude oil tank with 5.000 m3 of oil sludge
Depends on technical ability of a refinery/terminal to accept the recovered
hydrocarbons

No. It helps to keep the technology green and environmentally friendly.
Moreover, it helps to avoid any damage to pipelines and/or other facilities

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?
ARKOIL Technologies Nederland B.V. – Innovative tanks cleaning system
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
