Process for treating acid gas in staged furnaces with inter-stage heat recovery and inter-stage sulfur production |
| abstract |
A process for treating acid gases comprising hydrogen sulfide comprises introducing a first acid gas and a first oxygen-containing gas into a reducing furnace to produce a first oxidized gas stream, cooling the first oxidized gas stream in a first heat recovery system, introducing the cooled gas stream into a sulfur condenser to produce a sulfur-stripped gas, introducing the sulfur-stripped gas and a second oxygen-containing gas into an oxidizing furnace to produce a second oxidized gas stream and cooling the second oxidized gas stream in a second heat recovery system. The first acid gas can be acid gas comprising hydrogen sulfide produced in refineries. The spent acid can be spent sulfuric acid from a sulfuric acid alkylation process. The cooled second oxidized gas stream can be further treated in a spent acid recovery plant or a sulfur recovery unit. |
