I’m seeking help from those who are well-versed in the methanol production process (Linde process). How is PSA hydrogen produced? Is it from that remaining material?

As the title suggests, I hope some expert can explain this to me
It’s about having a good understanding of the methanol synthesis process, how high-concentration hydrogen is produced, and the detailed procedural steps
High-purity hydrogen can be extracted by PSA or separated by cryogenic methods
PSA hydrogen production is pressure swing adsorption, which involves adsorbing the components in gas except hydrogen under high pressure to produce high-concentration hydrogen. Under reduced pressure, the adsorbed gas is desorbed, and then the next adsorption cycle begins under increased pressure.

PSA pressure swing adsorption involves using molecular sieves and activated carbon to adsorb the process gas separated by high-pressure separators, thereby removing impurities such as carbon monoxide, small amounts of methanol, and carbon dioxide, to produce hydrogen with a high concentration (99.99%) for use in subsequent processes. Generally, the hydrogen-to-carbon ratio in synthesis is kept a bit higher to ensure the hydrogen pressure downstream. If you have any more questions, feel free to ask me
