pressure absorption tower

It showed that the propane recovery rate of new process would be 23%~ 27% higher than that of cryogen refrigeration process at the same refrigeration temperature. To increase the absorption tower pressure appropriately was good to improve the propane recovery rate.

本文实例研究表明：相同制冷温度下，冷剂制冷-油吸收复合工艺的丙烷回收率比原冷剂制冷工艺可提高23%～27%。

Then, the liquid is desorbed at atmospheric pressure, the liquid at the exit of the distilling tower contains only 0.014% of ammonia and 0.006% of CO 2, and the desorbed gas is returned to the absorbers in series for circulating absorption and separation.

分离游离氨后的溶液在常压下进行解吸，蒸馏塔出口液体含NH3和CO2量仅为0.014%和0.006%，解吸气回串联吸收器进行循环吸收分离。
