METHOD OF SEPARATION OF WATER-GAS-PETROLEUM MIXTURE Russian patent published in 1998 - IPC

FIELD: petroleum production industry, in particular, methods of conveyance and separation of petroleum well products at gathering, preparation and conveyance of petroleum. SUBSTANCE: the method consists in laminar flow of water-gas-petroleum mixture, its separation into a bundle of flows and, after separation of each flow in the bundle into phases, their confluence into a common flow. The conveyed flow is successively transferred in the horizontal and inclined directions; in these directions only the nucleus of the conveyed flow is subjected to separation into a bundle of flows; in the horizontal direction the flows in the bundle are transferred in a helical generating line, and in the inclined direction the flows in the bundle are transferred in parallel, at an opposing bubbling of the flow in the inclined direction - by bubbles of gas with a chemical composition identical or equivalent to the separated gas phase. EFFECT: facilitated procedure.
