A process for component separation in a polymer production system, the process comprising: (a) separating a polymerization product stream into a gas stream and a polymer stream; (b) processing the gas stream in one or more distillation columns to yield a light hydrocarbon stream, wherein the light hydrocarbon stream comprises ethylene and ethane; (c) contacting at least a portion of the light hydrocarbon stream with a purged hydrocarbon adsorber to yield a loaded hydrocarbon adsorber and a non-adsorbed gas stream, wherein at least a portion of the ethane is selectively adsorbed by the purged hydrocarbon adsorber at a first pressure to yield adsorbed ethane, and wherein the non-adsorbed gas stream comprises recovered ethylene, wherein the recovered ethylene comprises at least a portion of the ethylene of the light hydrocarbon stream, wherein the hydrocarbon adsorber comprises a zeolitic imidazolate framework; (d) contacting at least a portion of the loaded hydrocarbon adsorber with a sweeping gas stream at a second pressure to yield an unloaded hydrocarbon adsorber and a recovered adsorbed gas stream, wherein the recovered adsorbed gas stream comprises at least a portion of the sweeping gas stream and at least a portion of desorbed ethane, and wherein the desorbed ethane comprises at least a portion of the adsorbed ethane, wherein the first pressure is greater than the second pressure by equal to or greater than 400 kPa; and (e) contacting at least a portion of the unloaded hydrocarbon adsorber with at least a portion of the sweeping gas stream at the first pressure to yield the purged hydrocarbon adsorber and a spent sweeping gas.
