10000 Methanol off-gas hydrogen extraction
Thread Content
There are too many general discussions on this forum, which don’t help those who are new to pressure swing adsorption very much. I hope that the experts on this forum can provide more practical assistance to those who want to learn about pressure swing adsorption. I’ll take the example of methanol exhaust gas at 10,000 NM3/h; I encourage everyone to actively participate in the design discussions. Raw gas flow rate: 10,000 Nm3/h. Pressure: 2.6 MPa (G). Temperature: 40. Composition: H2: 58.07%, N2: 16.38%, CO: 13.08%, CH4: 3.05%, CO2: 9.42%. Product requirement: H2 ≥ 98%. Questions: 1. What process should be used? 2. The calculation process for determining the dosage of various adsorbents and their respective dosages? 3. Calculation of the adsorption tower? 4. Hydrogen recovery rate?

Moderator, please do the calculations and also let everyone learn about it*; it would be great if there was a detailed explanation of the process!
16 tower purge process, yield 92%； The adsorption capacity is about 230 tons; a commonly used type will suffice.
Is there a calculation process? I’ll explain it to everyone; I’ll just state the conclusion, as many people still don’t understand. Thank you!
