Derating

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.
