A process for component separation in a polymer production system, comprising: separating a polymerization product stream into a gas stream and a polymer stream; contacting the polymer stream with a purge gas to yield a purged polymer stream and a spent purge gas stream; introducing the spent purge gas stream to a compressor to produce a compressed gas stream; introducing the compressed gas stream to a first separation unit to produce a first hydrocarbon stream and a membrane unit feed stream; introducing the membrane unit feed stream to a membrane unit to produce a first recovered purge gas stream and a retentate stream; introducing the retentate stream to a second separation unit to produce a second hydrocarbon stream and a PSA unit feed stream; and introducing the PSA unit feed stream to a PSA unit to produce a second recovered purge gas stream and a tail gas stream.

Several embodiments of the present technology are directed to the removal of one or more air pollutants using cooling and/or calcium-containing particles. In some embodiments, a method for removing air pollutants comprises flowing a gas stream having calcium-containing particles and one or more of mercury or hydrochloric acid molecules, and cooling the gas stream, thereby causing at least a portion of the calcium-containing particles to adsorb to the mercury and/or hydrochloric acid molecules in the gas stream. The method can further comprise, after cooling the gas stream, filtering the gas stream to remove at least a portion of the calcium-containing particles having adsorbed mercury and hydrochloric acid.

The present invention relates to a system (100) for dry sorption. The system comprises a gas inlet (130) through which exhaust gas from processing industry is flowing into the system (100), a velocity increasing device which is arranged downstream of the gas inlet (130), and a reaction chamber (140) is arranged downstream of the velocity increasing device. The exhaust gas is brought into contact with the sorbent from a sorbent distributor (150) in the reaction chamber (140), wherein the velocity increasing device is a booster (110) and comprises a plurality of resistances to the flow of gas for creation of a turbulent flow of exhaust gas at the outlet of the booster for enhanced sorption. Further, the present invention0relates to a method for cleaning exhaust gas from processing industry utilizing the system (100) for dry sorption.

Process and apparatus for producing helium, neon, or argon product gas using an adsorption separation unit having minimal dead end volumes. A second separation unit receives a stream enriched in helium, neon, or argon, and a stream is recycled from the second separation unit back to the adsorption separation unit in a controlled manner to maintain the concentration of the helium, neon, or argon in the feed to the separation unit within a targeted range.

A method of purifying a gas composed of a product gas and one or more impurity gases including combining a feed stream with a second stream thereby forming a combined feed stream, introducing the combined feed stream into a pressure swing adsorption device, thereby producing a high purity product gas stream and an off-gas stream, and introducing the off-gas stream into a membrane separation device, thereby producing a gas stream lean in product gas and a permeate stream.
