OIL DEHYDRATION METHOD Russian patent published in 2015 - IPC E21B43/34 B01D17/04

Abstract RU 2540711 C1

FIELD: oil and gas industry.

SUBSTANCE: method includes dispersion of wash water in oil emulsion in the pipeline with streamline conditions of oil emulsion at the pipeline site downstream the point of deemulsifier delivery. Delivery of wash water to the pipeline is made through disperser made as a tube installed so that it may be moved across the pipeline cross-section with opening at the end directed towards flow of oil emulsion. The ratio of wash water flow rate from the disperser and rate of oil emulsion in the pipeline is maintained within the range of (10÷12):(0.2÷0.5).

EFFECT: improved degree of dehydration and desalinisation, provision of dehydration and desalinisation at change in liquid level in the pipeline.
