USE OF EXPANSION MACHINES IN GAS SCRUBBERS

A method for operating a gas scrubber (G) is disclosed in which components are removed from crude gas (3) by scrubbing with a chemical or physical scrubbing medium (3) to obtain pure gas (4) present at elevated pressure which, after heating (E3), is introduced into an expansion machine (T) which aft...

Beschreibung
Zusammenfassung:	A method for operating a gas scrubber (G) is disclosed in which components are removed from crude gas (3) by scrubbing with a chemical or physical scrubbing medium (3) to obtain pure gas (4) present at elevated pressure which, after heating (E3), is introduced into an expansion machine (T) which after work-performing decompression the pure gas (4) leaves at an exit temperature. The amount of heat(E3) supplied to the pure gas (4) during heating (E3) thereof is deliberately altered to approximate the exit temperature thereof to a predetermined target value at all times. 本发明涉及种用于操作气体洗涤器(G)的方法，其中通过用化学或物理洗涤介质(3)洗涤从粗气体(2)中除去组分以得到升高压力下的纯气体(4)，所述纯气体在加热(E3)之后通入到膨胀机(T)中，该纯气体(15)经过作功减压之后在出口温度下离开所述膨胀机(T)，其特征在于，在纯气体(4)的加热(E3)期间有意地改变向纯气体(4)供应的热量(E3)以使其出口温度始终接近预定的目标值。
