Title: Process for the simultaneous absorption of ammonia and hydrogen sulphide from industrial gases
IPC: C10K1/10
Filed: 1926-11-26
Abstract: 285,999. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). Nov. 26, 1926. Materials for purifying gas. - Sulphuretted hydrogen and ammonia present in industrial gases are absorbed by washing with an aqueous ammonium sulphite-bisulphite mixture having a ratio of sulphur dioxide to amonia, of 1 : 1.2 to 1.75. Washing liquors having contents of ammonia near the lower limit absorb the sulphuretted hydrogen most readily, and they give off small amounts of sulphur dioxide into the gas stream which necessitates a second washing with liquor having a content of ammonia at or near the upper limit. More than two stages may be used and the first stage may be conducted above or below the dew point. When the gas is coaled before it is washed, the gas liquor thereby condensed may be worked up into concentrated ammonia and reintroduced into the process as such or as ammonium bisulphite, in order to maintain the desired composition of the wash liquor.
