What is the maximum pressure at which hydrogen can be produced using pressure swing adsorption methods, both domestically and internationally?
Tianyi has lifted 50 kilograms before, at CNOOC
Can it go any higher? Because in high-pressure hydrogen recovery, reducing the pressure means increased energy consumption
I’m really at a loss with you. The pressure is always at atmospheric pressure; it only becomes high pressure when compressed. Energy is conserved, so there’s no increase in energy consumption.
Your recycled hydrogen is at high pressure; do you have to reduce it to low pressure before feeding it into the PSA? And then boost the voltage again? ? I still don’t understand what you’re saying. The more stress you have, the less energy-efficient it is, right?
It’s nothing but issues related to the upstream and downstream aspects. The main processes for hydrogen production and extraction are just those a few; there is no need to use high pressure for hydrogen recovery. The intake pressure is designed, bro.
Your thinking is too limited. It’s all about upstream and downstream processes – there are only a few options for hydrogen purification. But for example, if your entire facility operates under a hydrogen pressure of 10 MPa, then the hydrogen to be purified also has a pressure of 10 MPa. However, current hydrogen purification technologies can handle at most 6 MPa. As a result, you need to reduce the inlet pressure, and when hydrogen is fed into the facility again, you have to raise the pressure of the purified hydrogen from 6 MPa back to 10 MPa. What’s with these upstream and downstream issues? Is the intake pressure designed? Maybe you haven’t done high-pressure hydrogenation before
Hehe, I don’t want to argue with you. It’s obvious you’ve never designed a PSA system – the outlet hydrogen pressure has little impact; if you output at 5 atm, that’s the pressure after compression. The inlet and outlet pressures of the PSA system affect its hydrogen purity and recovery rate.
Is it the energy consumption issue? How much energy is consumed per lift and drop?
