Description

technical field [0001] The invention relates to a device and method for separating oil-water two-phase mixed liquid, in particular to a composite oil-water separation system and separation method applied to onshore and offshore oil production platforms. 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. [0003] The separation principles currently used are: gravity, centrifugation, filtration, electrostatic, demulsification, etc. The initial separation equipment generally adopts one separation principle for oil-water separation. In recent years, the combination of multiple separation principles for separation equipment is the development direction. For example, the patent publication number: CN2569538Y, a high-efficiency oil-water separator, describes a separation device that mainly adopts the principle ...
