Selective H 2 S Absorption in Aqueous Tertiary Alkanolamine Solvents: Experimental Measurements and Quantitative Kinetic Model
Abstract
In the treatment of many fuel gases such as biogas, natural gas, syngas, and so on, tertiary alkanolamines play an important role in the selective removal of H 2 S with respect to CO 2. The selectivity might be required for various reasons: to respect more stringent H 2 S specifications, to optimize the performance of the Claus unit, to lower the cost of CO 2 capture, and so on. The
