RSD Capacity is defined in terms of throughput of ultra-pure hydrogen at one atmosphere from a feed gas of commercially pure hydrogen at 250 PSIG, e.g., an RSD-100 will deliver 100 SCFH under these conditions. The relationship between pressure and throughput, however, is not linear.
The following block can be used to calculate the size of a purifier required to deliver specific flows at various pressure combinations.
The following rules apply:
The Feed Pressure must be greater than the Product Pressure.
The Feed Pressure must not exceed 270 PSIG.
To derate purifiers for extraction of hydrogen from highly crude streams (e.g., dissociated ammonia), consult the factory.
