Regeneration system for absorbing hydrogen sulfide and carbon dioxide

2015-10-06View Original

Thread Content

Does the hydrogen sulfide concentration in the regeneration tower decrease gradually? Is it possible for the hydrogen sulfide concentration at a certain tray level to be higher than that of the rich liquid?

Under normal conditions, the hydrogen sulfide content in the amine solution within the regeneration tower decreases gradually from the feed point onward. It is impossible for the hydrogen sulfide concentration at any tray level to be higher than that in the rich liquid.

In a regeneration system that selectively absorbs hydrogen sulfide, is it possible for hydrogen sulfide to take the place of carbon dioxide?
