SEPARATING MEDIUM AND METHODS SUITABLE FOR SEPARATION OF WATER-HYDROCARBON EMULSIONS WITH LOW SURFACE TENSION AT INTERFACES Russian patent published in 2015 - IPC B01D17/04 

Abstract RU 2540305 C2

FIELD: process engineering.

SUBSTANCE: separating media, separating modules and methods of separation are used for separation of water from water-hydrocarbon emulsions and comprises coalescing ply of fibrous nonwoven material for intake of said emulsion and water coalescing. Note here that coalesced water drops feature diameter of 1 mm or larger. Ply of fibrous nonwoven material for retention of drops in lower stream of coalescing ply with surface area defined by BET method of 90 m2/g or larger and sufficient for maintaining of coalescent water drop size for their separation from hydrocarbon.

EFFECT: production of new media for support and protection purposes.
