Process for disposal of mercaptans |
摘要 |
The invention provides a process for disposal of mercaptans, the process comprising the steps of: (a) contacting a feed gas stream comprising mercaptans with liquid sulphur in a sulphide producing zone at elevated pressure and at a temperature in the range of from 300 to 450° C. to obtain a liquid stream comprising sulphur and sulphide compounds; (b) optionally separating the liquid stream obtained in step (a) into a first liquid phase enriched in liquid sulphur and a second liquid phase enriched in sulphide compounds; (c) combusting at least part of the sulphide compounds at elevated temperature in the presence of an oxygen-containing gas in a sulphur dioxide generation zone using a sulphide burner to which burner oxygen-containing gas is supplied, whereby at least part of the sulphide compounds is converted to sulphur dioxide to obtain a gas stream comprising sulphur dioxide.
