Is a pressure setting of 0.23 MPa at the end of PSA sequential operation a bit low?
Thread Content
The hydrogen content in the purified gas produced by our plant is 40 percent; increasing the adsorption time has little effect. Could it be that the amount of gas released during the process is too high?
How much has the adsorption time increased now? By increasing the adsorption time, does the purity remain unchanged?
Our forward bias of 0.18 is not low at all!
Increasing the adsorption time can only increase the hydrogen yield, right?
Increasing the adsorption time helps to obtain the maximum amount of hydrogen; reducing the adsorption time, on the other hand, contributes to improving the purity of the hydrogen. If the desorption time is too long, it is necessary to prevent impurity components from lowering the quality of the hydrogen in the desorbed gas. We set the forward pressure at 0.23

It’s not a problem with the raw materials; it’s an PSA issue – the adsorption time isn’t sufficient to determine the hydrogen content in the gas to be analyzed
0.23 is not low; what is the purity of hydrogen in the raw materials used by the poster, and what is the hydrogen content in the exhaust gas as designed?
Is the hydrogen content in the raw materials too high? The lowest pressure set at 0.23 Mpa is already not low enough.
