Optimal operating temperature for PSA purification of hydrogen produced by hydrocarbon steam reforming
It is mainly a problem related to saturated water vapor; at low temperatures, less saturated water is carried into the adsorbent, which prevents the adsorbents in the lowest layer from becoming saturated and thus avoids a decline in the adsorption capacity of the fillers in the upper layers. The temperature requirement during design is usually <40°C.
Our operating temperature requirement is no more than 40°C; the optimal adsorption temperature for PSA is preferably between 25°C and 30°C, with an adsorption pressure of between 2.2 and 2.4
The hydrogen extraction temperature for PSA should not be too high, as this can easily affect the adsorption efficiency. I used to have a client whose temperature was too high before going through pressure swing adsorption; as a result, the CO levels after the PSA process were not up to standard.
