How is hydrogen and carbon monoxide separated in the coal-based ethylene glycol production process?
Thread Content
How is hydrogen separated from carbon monoxide in the coal-based ethylene glycol production process? After the shift reaction, low-temperature methanol washing is carried out, and then hydrogen and CO are separated? Or any other processes – please advise! Thank you!
Pressure swing adsorption for membrane separation or cryogenic applications is also an option, though it has high energy consumption
For the separation of H2 and CO, PSA or a cryogenic box can be used; PSA is employed for smaller-scale applications.
