pressure, and temperature for the process streams at the following points are
required for the best results. The minimum data required are indicated by
asterisks below:
– Feed gas ahead of pretreat system
Gas chromatograph (GC) analysis* – note that even natural gas feed will have
variable composition
You especially need the moles of carbon per mole of feed*
Flow rate*
– Feed pretreat system inlet
Feed gas analysis from above
Flow rate of feed and recycle hydrogen
– Reforming furnace inlet
Composition calculated from pretreat system inlet after reactions plus process
steam flow
Flows for feed gas and steam*
