TL;DR: In this article, a process for the fractionation of a gaseous mixture containing hydrogen, light aliphatic hydrocarbons and light aromatic polycyclic aromatic compounds is described.
Abstract: A process for the fractionation of a gaseous mixture containing hydrogen, light aliphatic hydrocarbons and light aromatic hydrocarbons wherein following compression of the mixture and separation of one or more light fractions, a gas is contacted with light aliphatic hydrocarbons and then hydrogen is separated by permeation. A series of distillation steps makes it possible to isolate the aliphatic hydrocarbons and the aromatic hydrocarbons subsequent to the separations.

TL;DR: Procede de fractionnement d'un melange gazeux renfermant de lhydrogene, des hydrocarbures aliphatiques legers and des hydro carbures aromatiques leger as discussed by the authors.
Abstract: Procede de fractionnement d'un melange gazeux renfermant de l'hydrogene, des hydrocarbures aliphatiques legers et des hydrocarbures aromatiques legers. Apres compression du melange (7) et separation d'une ou plusieurs fractions legeres (3 et 5), on met en contact le gaz (12) avec des hydrocarbures aliphatiques legers (13) puis on en separe l'hydrogene par permeation (16). Des distillations (23 et 25) permettent d'isoler les hydrocarbures aliphatiques (27) et les hydrocarbures aromatiques (26). Le procede est econome en energie et evite des cristallisations indesirables.

TL;DR: In this article, a process for treating a purge vent stream from a polymer manufacturing operation, the vent stream containing a polymer, such as ethylene or propylene, and a purge gas such as nitrogen, is described.
Abstract: A process for treating a purge vent stream from a polymer manufacturing operation, the vent stream containing a polymer, such as ethylene or propylene, and a purge gas, such as nitrogen. The invention involves three separation steps: condensation, flash evaporation and membrane separation. The steps are integrated together in such a way as to provide a good separation between the components, and to avoid creation of secondary streams that need additional treatment.

TL;DR: An improved process and process train for hydrogen separation and production from gas streams containing hydrogen and light hydrocarbons is described in this paper, which includes both recovery of hydrogen already in the stream by membrane separation and PSA, and production of additional hydrogen by steam reforming of the hydro-carbons.

TL;DR: In this article, a process for treating gas streams containing hydrogen and hydrocarbons is described, which includes a membrane conditioning step to remove C 5 -C 8 hydrocarbon, followed by a selective adsorption or membrane separation step to separate hydrogen from methane.
Abstract: A process for treating gas streams containing hydrogen and hydrocarbons. The process includes a membrane conditioning step to remove C 5 -C 8 hydrocarbons, followed by a selective adsorption or membrane separation step to separate hydrogen from methane. The membrane conditioning step uses a membrane selective for C 5 -C 8 hydrocarbons over hydrogen.

TL;DR: A treatment process for a hydrogen-containing off-gas stream from a refinery, petrochemical plant or the like is described in this article, which includes three separation steps: condensation, membrane separation and hydrocarbon fraction separation.
Abstract: A treatment process for a hydrogen-containing off-gas stream from a refinery, petrochemical plant or the like The process includes three separation steps: condensation, membrane separation and hydrocarbon fraction separation The membrane separation step is characterized in that it is carried out using a polymeric separation membrane that is selective in favor of hydrocarbons, including methane, over hydrogen, so that the hydrogen-enriched stream is delivered at high pressure
