Steam is supplied into the tank

Moving through specially designed nozzles, steam energy is converted and has a heating effect on the oil sludge.

Steam is supplied into the tank
  • No personnel inside the tank until its total degassing
  • Technology is applicable for cleaning of damaged tanks and tanks in critical condition
  • Technology is applicable to any tank size, type and design
Steaming of the tank walls

Simultaneously with the washing process which saves energy costs. Steaming allows to completely neutralize all pyrophoric compounds

Steaming of the tank walls
  • No chemicals or crude oil used
  • Technology is applicable at potentially hazardous facilities
  • Complete neutralization of pyrophoric compounds
Sludge separation

Into three fractions: oil, water, sediments. Recovery of up to 97% of oil organic part. Net profit instead of paying costs for waste disposal.

Sludge separation
  • No weather or seasonal restrictions
  • Maintaining the integrity of the tank steel structures
  • Simultaneous tank cleaning and oil recovery
Oil product without sediments

The pumped-out oil almost does not contain any sediments, as a result, there is no technological process breakdown and pipeline wear. The water condensed during steaming is safe and is drained into the industrial sewage.

Oil product without sediments
  • Minimum volume of sediment for disposal
  • No weather or seasonal restrictions
  • No harmful emissions to the atmosphere

Our experience

We have been executing complex tank cleaning projects since 2008.

Tanks of all types and sizes at oil refineries, pumping stations, product and raw material bases, oil terminals, power plants and boiler houses, including damaged and emergency tanks, tanks with damaged bottom, pontoons flooded and dropped to the bottom.

Заказчик: BP Raffinaderij Rotterdam B. V. 2015г.
  • Тип резервуара: 120 000 м³
  • Объем шлама: 6 500 м³
  • Сроки реализации: март-апрель 2015

Сложность проекта заключалась в том, что зачистка не производилась в течении 12 лет, в высокой температуре плавления нефтешлама, а также в большом объеме резервуара.

На протяжении длительного времени ни одна подрядная организация не справилась с поставленной задачей.

Нефтеосадок был приведен в жидкое состояние с помощью мобильного парогенератора. Высокоточные газовые анализаторы были установлены внутри и снаружи резервуара для обнаружения любых выбросов в атмосферу - выбросов не обнаружено.

Заказчику было возвращено 100% нефтепродукта
