The methanol content in the hydrogen purification gas produced by low-temperature methanol washing is high.

What is the reason for the high methanol content in the purified hydrogen gas produced by low-temperature methanation?
Yes, the methanol content in the purified gas produced by our Luchi process is relatively high; I’d like to ask for some advice as well
The main general reasons are as follows: 1. There are issues with the tower equipment itself – insufficient separation space at the top of the tower, low efficiency of the demister, and methanol entrainment； 2. High temperature of the gas at the top of the tower: insufficient cooling capacity in the system, and high temperature of the methanol used for washing
