The results showed that the heat taken from the feed section should be the same as in the double tower case, and the added reboiler should be located in the middle of the desorption section.
Nitrogen impurity adsorption when absorption tower up to a certain extent, reduce pressure desorption of zeolite molecular sieve, absorbent regeneration, recycling USES.
