GAS SCRUBBER WITH BUILT-IN HEAT EXCHANGER Russian patent published in 2015 - IPC B01D53/18 

FIELD: oil-and-gas industry.

SUBSTANCE: invention relates to a gas scrubber. The gas scrubber contains a gas washer designed as a vertical cylinder with one or several heat exchangers which are built-in into its housing for cooling of a gas-liquid mix formed by a gas to be cleaned and flushing liquid. The heat exchangers consist of vertically located thermal sheets and have a cross section which in each case conforms to common cross section of the gas washer. The gas-liquid mix flows through gaps between thermal sheets whereas cooling liquid flows in thermal sheets. Down the flow in front of the top heat exchanger the sheets guiding a flow are mounted which are designed as rectangular plates parallel to each other and located in such a way that their lower edges pass parallel to the top edges of thermal sheets with the gap D 5 - 15 cm and the horizontal average distance (B) between the guiding sheets is equal to average distance between thermal sheets, sheets are located at an angle F to a vertical axis of the gas washer, that is less than 90°, and their depth E is 10-30 cm.

EFFECT: invention allows to improve efficiency of heat exchange.
