TL;DR: In this article, the authors examined whether a hybrid membrane and cryogenic process can be utilized instead of using a large-scale O2/N2 membrane to create oxygen enriched air, which is then turned into high purity oxygen using cryogenic distillation.
TL;DR: In this article, the potential for a hybrid process combining membrane and cryogenic separation to achieve efficient post-combustion carbon capture has been investigated through a simulation study, which combines a first step CO2 pre-concentration with a membrane unit and a second step CO 2 cryogenic condensation.

Abstract: A method and system for liquifying natural gas using a cryogenic process is described. The method is well suited high methane purity natural gas which can be used as a vehicle fuel. The invention utilizes residue gas (210) from a cryogenic plant (1) as a natural gas feedstock. The natural gas feedstock is condensed by heat exchange with the overhead gas (208) from the demethanizer (60) of the cryogenic plant (1). In the preferred embodiment of the invention the pressure of the condensed natural gas is reduced to a level at which it can be readily stored and transported by expansion through one or more Joule-Thomson valves (92, 94, 96).
