APPARATUS AND PROCESS FOR REMOVAL OF HYDROGEN SULFIDE |
摘要 |
An apparatus and process is provided for the removal of hydrogen sulfide from gases and for restoration of hydrogen sulfide removal capacity in nitrogen-treated carbonaceous chars which have become exhausted for hydrogen sulfide capacity when used for the removal of hydrogen sulfide from gas streams. The apparatus has a matrix of removable canisters which contain the nitrogen-treated carbonaceous chars. This process entails directing the gas containing hydrogen sulfide through the canister, washing the spent carbonaceous char with water by flushing/dynamic washing through the canister to remove the majority of the hydrogen sulfide reaction products. By the use of this process a significant proportion of the original hydrogen sulfide capacity of the nitrogen-treated carbonaceous char is recovered and the canisters can be recycled a large number of times.
