Abstract

<PICT:0912091/III/1> Liquid absorbent, which has been used for selectively absorbing an ingredient of a gaseous mixture, is treated to expel the gas by passing humid air therethrough, the humid air being prepared by first passing air through liquid absorbent which has already been stripped of gas, and then treating the air with warm water so that it attains a humidity of 95-100% saturation and a temperature which is 5 DEG -15 DEG C. above the temperature of the unstripped absorbent. The process is particularly suitable for the removal of gaseous weak acids (e.g. CO2, H2S or HCN) from their solutions, the absorbent liquid being, for example, an alkaline solution or an organic solvent. Thus, the removal of H2S from sodium carbonate solution, and the removal of CO2 from potassium taurinate solution, are mentioned. In the drawing, the liquid absorbent is sprayed down a packed column 19 and is stripped therein by a countercurrent of humid air which is produced in packed tower 1. Tray 7, having covered vents, divides tower 1 into two parts, air entering the lower part through pipes 9 and 10 and moist air leaving the upper part through pipe 23. Stripped absorbent from column 19 enters the lower part of tower 1 through spray 3 and runs from the base of the tower into receiver 14. Water from tank 17 is pumped by pump 16, through heater 15, to the distributer 6 in the upper part of tower 1, while water collecting in tray 7 flows back to tank 17. Make-up water, to replace that consumed in moistening the air, is fed into tank 17, the flow of make-up water being controlled by the level in tray 7. Where the absorbent liquid is a solution, the passage of air through it, in the lower part of tower 1, alters the concentration of the solution. The concentration may be maintained at the desired value by means of impulse transmitter 12 in receiver 14. This transmitter, in response to changes in the concentration of the solution in receiver 14, operates the flow regulator 11, so that the proportion of air entering tower 1 through the pipe 9 is varied.
