Modeling of Thermodynamic Conditions for the Recovery of High-Purity Helium from Gas Mixtures by the Hydrate Formation Method

摘要

The modern technology for the recovery of helium from helium-containing natural gas is based on the low-temperature separation (fractional distillation) method, in which helium is separated from other gases in the course of their liquefaction. This method requires considerable energy and resource inputs. An energy-saving route to separate gas mixtures can be enrichment of natural gas with helium upon clathrate hydrate formation [1].
