Treatment of oil-containing emulsion

The crude oil extracted from the well contains formation water. Static settling often fails to completely separate oil from water. At the border of the interface of these liquids a layer of hard-to-destroy emulsion is formed, which is usually discharged into oil sludge collectors.

The services we offer allow to process such hard-to-destroy emulsions and obtain commercial oil as a result. A mobile container-type unit separates hard-to-destroy oil emulsions into oil, water phase and mechanical impurities (cake) by means of centrifugation:

  • The recovered commercial-quality oil is pumped through a field-mounted temporary pipeline into a storage tank for storaging and further use
  • The separated water is diverted into an existing discharge line designated for waste water
  • The accumulated mechanical impurities are loaded into containers for further disposal

Economic effect:

  • obtaining additional volumes of commercial oil from the emulsion

Environmental effect:

  • reducing the amount of oil contaminated waste as a result of emulsion processing

Large customers of this technology in Kazakhstan:

  • Ozenmunaigas JSC
  • Mangistaumunaigas JSC
  • Atyrau oil refinery LLP

Completed volumes of oil emulsion and oil sludge processing:

  • For the needs of Ozenmunaigas JSC for the period from 2008 to 2020 more than 1 million m³ of oil sludge was processed
  • For the needs of Mangistaumunaigas JSC in 2008, more than 60,000 m³ of oil sludge was processed
  • For the needs of «Atyrau oil refinery» LLP for the period from 2020 to 2021 processed more than 40000 m³ oil sludge.
