Ward, D J

Process and apparatus are claimed for the separation of gaseous and vaporous constituents from a feed containing the same. Vaporous feed components are absorbed into multiple primary lean absorber liquids and a secondary lean absorber liquid through contact between the feed and the absorber liquids in a multistage absorption zone. Gaseous feed components are withdrawn from the absorption zone. Rich absorber liquid is passed to a multistage stripping zone where gaseous feed components dissolved within the rich absorber liquid are removed and returned to the absorption zone. Stripped liquid, containing vaporous feed components, but being essentially free from gaseous feed components, is withdrawn from the stripping zone. Multiple and discrete primary lean absorber liquids are withdrawn from separate stages of the stripping zone and passed to separate stages of the absorption zone. 7 claims, 1 figure.
