为清洗液再生塔（1）从气体纯化区（4）自带和是充满了气态杂质。 在塔中，待再生的洗涤液是在温度为30以上的传质元件，它发源于逆流从下方并容纳汽提污染物进行至300℃。 具有用于装载洗涤剂的至少一个断开的电源（图7a，9a）和具有第二截止供给线下面的第二再生区（23）（参照图7B，9B），用于同一个加载的洗涤剂的上截止再生区（12）的再生塔。 第二个再生区和上部之间的体积比，可以关掉再生区为约至少1.5：1，在再生塔中装入洗涤剂的操作被首先导入到上部再生区（12），其中所述洗涤剂供应（7B，9B）到第二再生区（23） 关闭。 这里，要再生的洗涤剂流过上部再生区并且还通过第二再生区的至少一部分。 当在洗涤剂供应的上部区域中的堵塞发生（7A，9A）被关断并且洗涤剂供给器（图7B，9B）开到第二区。

Regeneration column (1) for washing liquid from a gas purification zone (4) comes and is loaded with gaseous impurities. In the column, the washing liquid is to be regenerated is conducted at temperatures from 30 to 300 ° C over mass transfer elements, said counter-current rises from below and accommodates the stripping contaminants. The regeneration column having an upper turn-off regeneration zone (12) with at least one disconnectable supply (7a, 9a) for loaded detergent and an underlying second regeneration zone (23) having a second turn-off supply line (7b, 9b) for the same loaded scrubbing. The volume ratio between the second regeneration zone and upper, disconnectable regeneration zone is about at least 1.5: 1. During operation of the regeneration column loaded detergent is first led in the upper regeneration zone (12), wherein the detergent supply (7b, 9b) is switched off to the second regeneration zone (23). Here, the detergent to be regenerated flows through the upper regeneration zone and also through at least part of the second regeneration zone. Upon the occurrence of blockages in the upper zone of the detergent supply (7a, 9a) is switched off and the detergent feeder (7b, 9b) opened to the second zone.
