1. A carbon dioxide recovery system, comprising:
a primary recovery system comprising a plurality of membranes;
a carbon dioxide (CO2) plant assembly fluidly coupled to a permeate of a membrane of the plurality of membranes, the CO2 plant assembly configured to provide a liquid CO2 product stream and a non-condensable stream; and
a standalone membrane assembly fluidly coupled to the non-condensable stream, and configured to separate the non-condensable stream into a hydrocarbon enriched stream and a CO2 enriched stream, wherein the CO2 plant assembly is fluidly coupled to the CO2 enriched stream.
