Separation of methane from nitrogen
Thread Content
There is a gas that contains only methane and nitrogen; what are some good ways to separate them?
Molecular sieve adsorption method, or liquefaction separation method
By looking at the processing volume and methane content, it can be determined whether there is significant value in recovery; low-temperature separation can be used to liquefy methane into LNG
Separation without altering the physical properties can be achieved by vaporizing methane using low-temperature and high-pressure methods. If the goal is simply to get rid of methane, it can be sent to high-temperature equipment to be burned.
