Medium-pressure gas decarburization-PSA production technology
Thread Content
This post was last edited by VinDin on 2010-12-9 at 11:58. The processes are becoming increasingly confusing these days, so I turn to the experts for help: 1. What are the impurity gases involved in PSA adsorption during the hydrogen production stage? What else is there besides N2? 2. The regeneration process and normal operation should proceed simultaneously; only different PSA purification tanks are used. What are the main components of the gas in the desorbed gas? What is the difference between the gas going to the degasifier converter and the gas going to the flare? 3. I lost track of the flow path of the gas after passing through the converter; where does the gas go after being processed by the converter?
1 There is carbon monoxide, carbon dioxide, methane. 2 Carbon monoxide, carbon dioxide, methane, hydrogen – there’s no difference. 3 It goes into the intermediate converter
1. CO, CO2, methane, etc. 2. The regeneration process and normal operation take place in different towers; no purification tank is used, and the impure gases in the adsorption bed are removed by reducing pressure. Analyzing the main gas in the air, which is CO2, along with small amounts of hydrogen ； The gas going to the degasifier is clean product gas, while the gas sent to the flare is usually desorbed gas. The content of active ingredients varies. 3. The gas coming out of the ammonia synthesis or methanol synthesis towers is generally recovered for use as useful gas before being sent to the fuel pipeline network to power boilers.
