Abstract: The process can be used in any hydrocarbon process in which it is desirable to recover hydrogen. The process can include catalytically reforming a hydrocarbon feed, a paraffin dehydrogenation to produce light olefins or a synthesis gas generating process. There is an effluent stream having hydrogen and hydrocarbons that is first sent to an adsorption zone to produce a pure hydrogen stream and a tail gas stream. The tail gas stream is then sent across a feed side of a membrane having the feed side and a permeate side. The membrane that is selected is selective for hydrogen over one or more C1-C6 hydrocarbons and light ends including CO, CO2, N2 and O2, and withdrawing from the permeate side a permeate stream enriched in hydrogen compared with a residue stream withdrawn from the feed side. The permeate stream is then recycled to be sent through the adsorption zone.

Abstract: A membrane unit is able to recover hydrogen from a resid waste gas stream. Two membrane units provide even greater hydrogen recovery. The membrane separation is performed at conditions that allow the pressure of the recovered hydrogen to enter into a second stage of compression, saving the expense of the first stage of compression.

Abstract: The invention involves a process for treating a gas stream from a hydroprocessor that contains hydrogen, methane and C2+ hydrocarbons. In embodiments of the invention, the gas stream is sent through at least two pressure swing adsorption units to produce a high quality hydrogen stream, a fuel gas stream containing most of the methane and a tail gas stream that is sent to a steam cracker. Lean gas from a gas plant and other refinery off gases may also be processed together with the gas stream from the hydroprocessor.

Abstract: Apparatuses and methods for reforming of hydrocarbons including recovery of products. A reforming-zone effluent is separated into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream may be passed separated into an H2 rich stream and a tail gas stream in a PSA. The tail gas may be passed through an absorber and then passed through a membrane to form a second H2 rich stream and a liquid stream. A second absorber is used to recover C3/C4 hydrocarbons. The two absorbers may be stacked on top of each other.

Abstract: Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is separated for forming an H2-rich stream and a first intermediate liquid phase hydrocarbon stream. The H2-rich stream is contacted with an adsorbent to form an H2-ultra rich stream and a PSA tail gas stream. The PSA tail gas stream is contacted with an H2/hydrocarbon separation membrane to separate the PSA tail gas stream and form an H2-ultra rich permeate stream and a PSA tail gas hydrocarbon-containing non-permeate residue stream.

Abstract: Processes and apparatuses for recovering a high purity carbon dioxide stream. A first separation zone that may include a cryogenic fractionation column provides the high-purity CO2 stream. A vapor stream from the cryogenic fractionation column is passed to a second separation zone to separate the CO2 from the other components. The second separation zone may include a pressure swing adsorption unit or a solvent separation unit. The second separation zone provides a hydrogen enriched gas stream that may be used in a gas turbine. The second stream from the second separation zone includes carbon dioxide and, after a pressure increase in a compressor, may be recycled to the first separation zone.
