Stripping operation amine regeneration

Function is to strip species from the liquid to produce a quality bottoms product for example, a solvent ready to be recycled as in glycol dehydration, amine absorption, extractive distillation or water that has been stripped of contaminants as in Sour Water strippers deodorize edible oils. Used to regenerate solvent for absorption or extractive or azeotropic distillation. Other equipment that is used for stripping include distillation. Section 4.2, gas-liquid separators. Section 5.1 and gas-liquid-liquid separation in flash drum. Section 5.4. The general characteristics of gas-liquid contacting are described in Section 1.6.1. Other operations that use this type of contactor include gas absorption. Section 4.8 reactors. Sections 6.13-6.16 and 6.19 and direct contact heat exchange Sections 3.7-3.9. 

The quantity of stripping vapor required depends upon the solution purity needed to achieve the required product gas purity, the stripping column height, the nature of the solution, the ratio of CO2/H2S in the rich amine solution, and the regenerator operating pressure.
