Patent ID: 8641017

Claim:
Device for absorption of at least one component chosen among gas and vapour into a liquid, based on an ejector principle and comprising a mixing zone in the form of a substantially straight tube immediately downstream of the ejector, characterized in that the device comprises an ejector ( 1 ) with a converging central liquid passage for providing the liquid to the ejector ( 2 ) and a substantially annular, sectioned aperture ( 4 ) for gas/vapour configured to allow the gas/vapour to be sucked into the ejector due to the motive force of the fluid, said aperture ( 4 ) generally surrounding the central liquid passage ( 2 ), wherein the annular, sectioned aperture ( 4 ) for gas/vapour is designed in a manner to cause the gas/vapour to enter the mixing zone with a velocity component that is inclined to the periphery surface of the tube to thereby provide a helical flow ( 6 ) downstream of the ejector ( 1 ) wherein the liquid is the sole motive fluid for the device.
