Molecular sieve membranes for N2/CH4 separation

Molecular sieve membranes for N2/CH4 separation

Jan 01, 2018 Nitrogen rejection is a challenging technical separation because of the similar molecular size of N 2 (∼0.36 nm) and CH 4 (∼0.38 nm). Several processes have been developed to treat natural gas to meet gas specifications.5 Many of these high-N 2 gas streams are diluted with low-N 2 gas to meet pipeline specifications. If this is not practical, an N 2 removal unit is …

Molecular Distillation High-Power Vacuum Distillations

Molecular distillation is a technology made exclusively for liquid-liquid separation. While traditional distillation does so with the boiling point difference separation principle, this method separates substances at the molecular level. This allows for a safer and purer technique of distillation. This method also produces a shorter residence ...
