What is the best process for purifying methane from coke oven gas? How much is the investment? Anyone who knows please let me know!
The composition of coke oven gas is much older. Not easy to separate. It seems that only CO/H2/CH4 is left in the purified gas and liquid after passing through the chemical production workshop.
Membrane separation supporting pressure swing or temperature swing adsorption separation
The low-temperature separation effect should be good, right? Its purity is guaranteed
Now the hot way is to purify first； Re-methanation, remove CO and CO2 ； Finally, pressure swing adsorption, membrane separation, cryogenics, etc. are used for separation and purification. ； It can be used for pipeline transportation of SNG, CNG, or LNG. This not only increases the CH4 production, but also reduces the difficulty of subsequent separation and purification. If the host needs it, he can tell you the scale and I can make a simple economic and technical plan for you. liujingangren@yahoo.com.cn
