Abstract
Hydrogen sulphide and water vapour are removed from a gaseous mixture by contacting with sulphur dioxide in a 90-99% aqueous solution of an inert, neutral, stable, organic solvent having a vapour pressure not more than 10 mm's. Hg., and a solubility in water not less than 2%, at 20 DEG C., and containing at least 2 atoms of at least one element other than C and H, at least one of which is O or S, and not more than 2 vicinal OH radicals. The water is absorbed by the solution and S particles are precipitated. A number of organic solvents are specified including the glycols, e.g. diethylene, triethylene, or propylene glycol, or the ether or ester derivatives thereof. The H2S-containing gases, e.g. sour natural gas, may be reacted with SO2 in the presence of the aqueous solution of the organic solvent in various ways, e.g. the SO2 may be dispersed in the sour natural gas in an absorption tower and the combined gaseous mixture absorbed in a descending stream of the aqueous solution of organic solvent, or the SO2 may be dissolved in the aqueous solution of organic solvent and the resulting solution, which should preferably contain less than 10% wt. of SO2, is contacted with a stream of sour gas ascending the absorption tower, or various combinations of such processes may be employed. The Specification refers to several plants for the removal of H2S from gaseous mixtures in detail with reference to accompanying drawings. The suspension of sulphur may be agglomerated by heating to melt the S, and the S is removed from the spent aqueous solution by decantation. Spent aqueous solution, after regeneration to remove SO2 and excess water absorbed, is recycled to the process. The SO2 may be formed by oxidizing one-third of the H2S in the gas mixture.
