Combined capacity for both Units.
In the amine units, lean amine solution will be fed to the amine contactor and absorbs the acid gases (H2S and CO2) in the inlet gas. The rich amine solution from the amine contactor will be flashed in the amine flash drum and routed to an amine still where acid gas is stripped from the amine solution with heat from vent gases generated from hot oil heaters. A small RTO (8MMBtu/hr) will be used to abate the amine still vent gases. Estimated destruction efficiency (DRE) for VOC and H2S by each RTO will be 99%. When RTOs are down for maintenance, emissions from the amine plants will be routed to an existing flare meeting the requirements of 40CFR 60.18. Flare operation will be limited to 288 hrs/yr.
