Industrial oil water separation method and system thereof

Abstract

The invention relates to an industrial oil water separation method and a system thereof. The method comprises the following steps that: (1) an oil water separation system consisting of a T-shaped pipe, shunts, volute pipes and gravity sedimentation separation box bodies is adopted and the composite principle of the centrifugation, gravity and bulge of oil and water is used to separate the oil from the water, (2) after oil water mixture is input into a horizontal total intake pipe, the entrance pressure of the first shunt is adjusted so that the oil water mixture enters the first shunt to be delaminated, (3) the oil water mixture enters the T-shaped pipe through a vertical pipe for further separation so that the mixture containing little oil phase liquid declines into a lower horizontal pipe, (4) the oil water mixture in an upper horizontal pipe enters the volute pipe of the first sedimentation separation box through the second shunt for centrifugal separation and the mixture distributed at the inner side of the volute pipe enters the second sedimentation box for gravity sedimentation separation, and (5) after the centrifugal separation of the oil water mixture in the lower horizontal pipe through the volute pipe in the third sedimentation separation box, the oil water mixture enters the fourth sedimentation separation box for separation.

Description

technical field [0001] The invention relates to a method and system for separating oil-water two-phase mixed liquid, in particular to an industrial oil-water separation method and system applied in marine production platforms, underwater production systems and onshore oil and gas field separation systems. Background technique [0002] In many industries, such as petrochemical enterprises, oil-water separation equipment is an important production equipment. Separation technology is crucial to the development of the industry. The separation principles currently used are: gravity, centrifugation, filtration, electrostatic and demulsification, etc. The initial separation equipment generally adopts one separation principle for oil-water separation. In recent years, the equipment that combines multiple separation principles for separation is developing direction. For example, a patent with a patent publication number of CN2569538Y is a patent for a high-efficiency oil-water sepa...

AI Technical Summary

Problems solved by technology

However, in actual production, it is often necessary to quickly separate a large amount of oil-water mixture. Gravity principle and membrane technology are effective separation technology means, but the processing speed of these two separation technologies is relatively slow, which leads to relatively poor equipment structure. complex, bulky
