Abstract
827,151. Purifying gases. GAS COUNCIL. Feb. 29, 1956 [March 1, 1955], No. 6078/55. Class 55 (2). In a process for removing H 2 S from gases such as coal gas the gas is washed with a solution of an organic dye base which will yield a readily oxidizable reduction product with H 2 S, the solution being regenerated by oxidation with air or oxygen. The dye base may be derived from a dye salt of the azine, triazine, oxazine or tri-phenylmethane classes, e.g. from methylene blue chloride. Methylene blue base may be made as follows :-To 100 c.c. of a 4% solution of methylene blue chloride in aniline, 0.5 c.c. concentrated ammonia solution is added. The solution is then reduced with H 2 S and extracted with an equal volume of water containing 5 c.c. concentrated ammonia solution followed by a second extraction, and if necessary further extractions, to remove all chloride ions. The solution is then aerated or oxygenated to yield a solution of methylene blue base. If during the process dye salts of sulphur oxy-acids are formed they may be converted back to the dye base by a treatment similar to the method of preparation described. Specification 827,152, [Group III], is referred to.
