ABSTRACT:
A reformer optimization system including the injection of non-reactive gas into hydrogen recycle gas for increasing hydrogen flow through a recycle compressor. Non-reactive gas is injected into hydrogen-rich gas fed to the compressor at least as early as the hydrogen-rich gas enters the compressor. The quantity of hydrogen is monitored, and the quantity of non-reactive gas injected is controlled in response to the hydrogen quantity. By maintaining a substantially constant molecular weight of the hydrogen gas, hydrogen content thereof is increased. The non-reactive gas is preferably at least one of a group comprising nitrogen, ethane and propane.
