1. A process for removing contaminants from a refinery gas, comprising:
recovering a process gas comprising ethylene and propylene from a steam cracker effluent recovered from a stream cracker in a steam cracker facility;
recovering a refinery gas from a refinery facility;
compressing the process gas in a plurality of compressor stages;
determining a pressure of the refinery gas;
selecting a compressor stage in the plurality of compressor stages for introducing the refinery gas using the determined pressure of the refinery gas, wherein the selected compressor stage is located after a first compressor stage and before a last compressor stage of the plurality of compressor stages;
introducing the refinery gas into the selected compressor stage to produce a combined gas comprising the process gas and the refinery gas; and
removing at least a portion of one or more impurities from the combined gas in the steam cracker facility to produce an upgraded combined gas lean in the one or more impurities.
