METHOD FOR PROCESSING WATER FOR EXTRACTION OF OIL BY THERMAL METHODS Russian patent published in 2005 - IPC

FIELD: oil extractive industry.

SUBSTANCE: method includes first stages of capturing energy of processed heat from high pressure steam separator, placed below steam generators. Then transfer of heat energy into heated separator and evaporator and heat exchanger is performed for distillation of bed water present in oil-bearing bed and restoration of distillated water and concentrated salt solution or hard product. Concentrated water steam from heated separator is circulated through evaporator and heat exchanger to support from 1% to around 50% of steam mass in the flow, returning into heated separator, and prevent pollution and forming of scale. Equipment includes separator for processed low pressure energy, heated separator and steam compression with forced circulation circuit to produce distillated water.

EFFECT: higher efficiency.
