Separation of hydrogen and carbon monoxide in the coal-to-ethylene glycol 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!
In ethylene glycol synthesis, the C/H ratio is 1:2; the syngas is transformed to adjust this C/H ratio, purified through low-temperature methanol washing, and then hydrogen and CO are separated
What are the concentrations and pressures of CO and hydrogen after low-temperature methanol washing? Is PSA used for the separation of CO and hydrogen? What is the hydrogen concentration in the CO-rich gas after separation?
The concentrations and pressures of CO and H2 are related to the gasification process and the low-temperature methanol washing process, with PSA being used to separate CO and H2 separately.
