What are the advantages and disadvantages of using PSA or cryogenic methods for the separation of methane and carbon monoxide? It would be best to have data to support it, thank you!
It seems nothing is easy; we have to wait for an expert to appear. Why is it necessary to separate carbon monoxide from methane?

Our company uses CO cryogenic separation technology to remove impurities such as hydrogen from the feed gas in the production of ethylene glycol; this method operates quite stably. If PSA is used, it requires more space and its operation is less stable; therefore, cryogenic separation technology is recommended. PSA technology is used for hydrogen purification.
It is gasified using a Lurgi furnace; the raw gas contains methane, and there’s nothing that can be done about it.
What is the target product?
Write down your components and proportions so that it’s easier to determine the goal
Cryogenic methods are relatively energy-intensive; PSA may not achieve as good a separation effect as cryogenic methods. Use cryogenic methods for large volumes and PSA for smaller volumes
This is a bit similar to air separation: use PSA for small volumes, and cryogenic treatment for large volumes!
Using cryogenic methods comes with high costs; PSA is an alternative, but special adsorbents are required, and these cannot be purchased easily from standard suppliers. It would be best if you could provide detailed information on your process conditions, target requirements, production volume, and the processes involved upstream and downstream, so that I can examine the situation more carefully for you.
