Does anyone know of cases of using membrane separation for hydrogen production from coke oven gas?

Does anyone know of any cases where coking plants use membrane separation to produce hydrogen from coke oven gas? Seeking advice, thank you!
Pressure swing adsorption is still more commonly used~~ Membrane separation is less common, but there must be mature technical solutions available; it’s just that customers don’t prefer it very much~~

The hydrogen production units at Liaoyang Petrochemical and Yanshan Petrochemical use dry gas membrane separation technology to concentrate raw materials such as hydrocracking dry gas, PSA separation gas, and hydrorefining dry gas to over 90%, and then purify them into hydrogen using new PSA systems. This approach allows for the use of improved raw materials in these hydrogen production units, reduces their operating costs, and enables the use of coking dry gas and non-permeate gas generated through membrane separation in order to increase hydrogen production while reducing energy consumption
Thank you for the advice. What you mentioned are all components related to petrochemical projects. I’m trying to find out whether coking plants (coal chemical industries) have implemented such projects.
Yutai Gas Co., Ltd. in Handan City, Hebei Province, Shanxi Guoxin Chint New Energy Co., Ltd., Shanxi Huayang Gas Co., Ltd., and Shanxi Juyuan Coal Chemical Co., Ltd. – all of these companies use coke oven gas to produce natural gas (CNG), and they employ membrane separation technology for this purpose. The principle relies on the fact that membrane separation technology can effectively separate hydrogen from methane. Coke oven gas contains a high level of hydrogen (usually over 50%), and membrane separation technology can easily increase the hydrogen concentration to over 90%. However, for hydrogen with a concentration of over 99%, PSA may be more stable. Both membrane separation and PSA technologies are already well-developed; the choice between them depends on your specific circumstances.
