A GRAVITY SEPARATOR, AND A METHOD FOR SEPARATING A MIXTURE CONTAINING WATER, OIL, AND GAS

摘要

A gravity separator comprises a vessel within which a mixture containing water, oil, and gas can separate under gravity to form vertically discrete oil and water layers and a gas phase. An inlet duct communicates with a vessel entrance for the mixture containing water, oil, and gas. The inlet duct of the gravity separator comprises injector means injecting a gaseous medium in a volume in the range of 0.01-1.9 Sm³ gaseous medium per 1m³ mixture into the mixture containing water, oil, and gas.
