PSA operation cycle

Thread Content

Hello everyone, what is the typical “adsorption cycle” duration for the PSA unit in your facility, in seconds?
Reply #22011-03-23
The number of towers varies, resulting in different processing loads and thus different adsorption cycles. The adsorption time can be adjusted according to the product quality; under conditions where the product quality permits, it should be extended as much as possible to improve the hydrogen yield.

We use the 10-2-4 process at Huaxi Institute. As you mentioned, increasing the adsorption time will likely lead to a decrease in hydrogen purity
