Abstract
Nitrogen or hydrogen is treated to reduce the concentration of an acidic constituent, e.g. CO2, H2S1CO SO2, Cl2, SiF4, HF or HCl, or an impurity, e.g. NH3. The treatment comprises feeding an absorbent having a preferential absorption for at least one component of the gaseous mixture into the top of a lined hole in the earth extending for more than 100 ft. downwards and more than 33 times the square root of the average cross-sectional area which is used for contacting, flowing the absorbent downwards in the treatment zone near the lower end of which the mixture is fed in to flow counter-currently to the absorbent at more than 100 p.s.i., maintaining a pressure additional to hydrostatic, in the zone of at least 3 times atmospheric, flowing from near the top of the zone the unabsorbed fraction of the mixture which is withdrawn from the hole and the enriched absorbent is withdrawn from near the bottom of the hole. The absorbent may be water, propylene carbonate or glycerol triacetate.ALSO:Sour natural gas is treated to decrease the concentration of an acidic constituent, e.g. CO2, H2S, CO, SO2, Cl2, SiF4, HF, HCl, HCN COS, mercaptans and if present a heavier hydrocarbon i.e. other than CH4, or a mixture of a light olefine i.e. C2H2, C2H4 or C3H6 and hydrogen is treated to obtain an olefine enriched fraction from which the olefine is recovered. The treatment comprises feeding an absorbent having a preferential absorption for at least one component of the gaseous mixture into the top of a lined hole in the earth extending for more than 100 ft. downwards and more than 33 times the square root of the average cross-sectional area which is used for contacting, flowing the absorbent downwards in the treatment zone near the lower end of which the mixture is fed in to flow countercurrently to the absorbent at more than 100 p.s.i., maintaining a pressure additional to hydrostatic, in the zone of at least 3 times atmospheric, flowing from near the top of the zone the unabsorbed fraction of the mixture which is withdrawn from the hole and the enriched absorbent is withdrawn from near the bottom of the hole. The absorbent may be an aqueous solution of butoxy diethylene glycol acetate, methoxy triethylene glycol acetate, water, propylene carbonate or glycerol triacetate.
