ABSTRACT:
An improvement has been found in the gas recovery section of a delayed coking process. In the improvement the compressor discharge is amine scrubbed to remove hydrogen sulfide. The compressor discharge is the entire vapor feed to the gas recovery section and contains about 90% of the hydrogen sulfide. This has been found to cause a significant drop in both the depropanizer and debutanizer pressure and allow a saving in the investment cost of the pressure vessel. Synergistically a reduced amount of hydrogen sulfide is present in the entire gas recovery section. The remaining 10% of the hydrogen sulfide is removed by amine scrubbing the fuel gas and propane/propylene fractions.
