GAS SCRUBBING METHOD AND DEVICE Russian patent published in 2015 - IPC B01D47/02 B01D45/12 

FIELD: oil and gas industry.

SUBSTANCE: mixture of gas and liquid is passed through a centrifugal separator. From the separator the scrubbed gas is output separately from washing liquid and liquid is returned to the vat section for circulation purpose. Gas is supplied to direct-flow centrifugal scrubber elements placed at direct-flow centrifugal plate. At that gas is warped thus creating vacuum zone in near-axial zone of the element. Liquid is supplied from vat section due to difference in pressure under the section of centrifugal separation and at the axis of centrifugal scrubber element. Liquid is supplied through vertical washing liquid feed tubes, which one end is fixed in near-axial zone of direct-flow centrifugal scrubber elements while the other end is lowered to liquid in the vat section.

EFFECT: developed effective method and device of gas scrubbing with liquid supplied without pump thus reducing energy consumption costs and quantity of washing liquid.
