CENTRIFUGAL COALESCING DEVICE Russian patent published in 2012 - IPC B04B5/12 B01D17/38 

FIELD: process engineering.

SUBSTANCE: invention relates to oil industry and may be used for demulsification in making stock-tank oil. Centrifugal coalescing device comprises device to create centrifugal force, inlet branch pipe and oil and water discharge branch pipes. Said to create centrifugal force is made up of flat Archimedean spiral communicated via tangentially tapering branch pipe with inlet branch pipe, top and bottom covers provided with oil and water discharge branch pipes arranged thereon. Channel is made between spiral coils to guide initial product from periphery to center. Oil and water discharge holes separated by web are made on covers, at spiral center. Said holes are aligned with water and oil discharge branch pipes. Web position over channel width is defined by percentage of oil and water in initial product.

EFFECT: higher efficiency, simplified design.
