Method for the removal of hydrogen sulfide present in gases |
| abstract |
This invention relates to methods for the removal of hydrogen sulfide from various gases containing hydrogen sulfide. In order to remove hydrogen sulfide, an aqueous solution containing a di(lower alkyl)amino-(lower alkanol) or triethylenediamine is used. In order to remove hydrogen sulfide selectively from gases containing carbon dioxide and hydrogen sulfide, an aqueous solution containing tert-butyldiethanolamine, triisopropanolamine, triethylenediamine or 2-dimethylamino-2-methyl-1-propanol is used. In order to remove both carbon dioxide and hydrogen sulfide from gases containing carbon dioxide and hydrogen sulfide, an aqueous solution containing a mono(lower alkyl)amino-(lower alkanol) is used. |
