Measures to improve the hydrogen recovery rate in dry gas hydrogen production via pressure swing adsorption PSA
Thread Content
In dry gas hydrogen production using pressure swing adsorption (PSA), the current operating procedure is 8-2-4, with 2 adsorption units and 4 pressure reduction units. If the procedure is changed to 8-1-4, will the processing load of the PSA increase and will the hydrogen recovery rate rise?
The yield of 8-1-4 is higher than that of 8-2-4, while the operational stability of 8-2-4 is better.
The processing capacity of 8-2-4 is high, and valve jamming can occur during single-tower adsorption, which is quite dangerous
