METHOD OF SEWAGE CLEANING BY SEPARATION |
摘要 |
FIELD: process engineering. ^ SUBSTANCE: invention relates to oil industry and may be used for cleaning sour oil-and-gas-containing effluents from emulsified oil, oil products and solid suspended particles. Sewage from first settler 1 is fed into second extra settler 2 arranged some 10-16 m higher that that first one. Surplus pressure first settler 1 is maintained equal to 0.4-0.8 MPa. Pressure in second settler 2 is maintained by gas exhaust to equal 0.01-0.03 MPa. Oil from settler 1 flows into settler 3. Gas is discharged from settlers 2 and 3 into low-pressure gas collection system. Sewage from settler 3 is fed into buffer tank 5 to be pumped over into formation pressure maintenance system by pump 6. ^ EFFECT: higher efficiency of sewage cleaning. ^ 1 dwg, 1 ex |
