Abstract: A non-transitory, processor readable medium stores instructions that, when executed by a processor, causes the processor to receive (1) an indication of a feed gas flow rate measured between a feed gas source and an internal combustion engine (ICE) and (2) an indication of an oxygen enriched air flow rate measured between an air separation unit (ASU) and the ICE. A measured equivalence ratio is determined based on a feed gas composition, the feed gas flow rate, and the oxygen enriched air flow rate. The instructions further cause the processor to generate at least one of a first signal to cause a change in revolution speed of the ICE, a second signal to cause a first flow control device to modify the feed gas flow rate, or a third signal to cause a second flow control device to modify the oxygen enriched air flow rate.
