Title: A process for removing ammonia and sulphuretted hydrogen from gases
IPC: C10K1/08
Filed: 1928-09-19
Abstract: 301,061. Hansen, C. J., (Assignees of Koppers Akt.-Ges., H.). Nov. 24, 1927, [Convention date]. Addition to 299,765. Materials for purifying; purifier waste, revivi. fying.-In a process according to the parent Specification for removing ammonia and hydrogen sulphide from gases the gases are subjected to a preliminary washing with the spent thiosulphate liquor, containing sulphide of iron, man ganese or zinc, from the main scrubbing opera tion, and the ammoniacal liquor so obtained is returned to the main washing liquor. The spent liquor rendered ammoniacal is returned to the main process. The gases may be cooled before the first washing to reduce the amount of ammonia to be dissolved in the spent liquor. Such proportion of hydrogen sulphide as cannot be removed by the thiosulphate scrubbing may be removed simultaneously with the preliminary washing by adding iron hydroxides which may be introduced by oxidation of the spent liquor by passing air therethrough. The ammonia content of the gases may be added to from other sources or supplemented by salts of alkalis or of magnesium or zinc. After washing out of ammonia by spent liquor a further portion of hydrogen sulphide may be removed before the thiosulphate scrubbing by washing with polythionate solutions or thiosulphate solutions containing free sulphurous acid. By removing hydrogen sulphide by means of iron hydroxidecontaining liquors before the main scrubbing process iron compounds are brought into solution without attacking the sulphur when revivification by treatment with sulphurous acid is effected and the sulphur is isolated by simple filtration. The purifying process may be effected at an elevated temperature and pressure.
