Abstract
In a continuous process for the selective absorption of constituents from a gas stream where a component is reacted to form absorbable constituents, recovery per unit volume of absorbent is improved by passing the gas through a low temperature mass absorption zone, a high temperature reaction-absorption zone and a final low temperature absorption zone, the absorption solution from the final absorption and reaction-absorption zones being combined to form the absorption solution of the mass absorption zone.
