1. A gas treatment system configured to treat an influent fluid stream including hydrocarbons and CO2, the system comprising:
an amine unit configured to separate the influent fluid stream into a first amine effluent stream including hydrocarbons and a second amine effluent stream including a connection pressure and comprising CO2; and
a reduction oxidation unit downstream of the amine unit, the reduction oxidation unit configured to receive the second amine effluent stream from the amine unit and operate at the connection pressure while releasing a reduction oxidation effluent stream including purified CO2, the purified CO2 corresponding to only the CO2 in the second amine effluent stream,
wherein the connection pressure includes a single pressure or a plurality of pressures at which both the amine unit and the reduction oxidation unit are configured to operate.
