Hi Evan, our refinery has energy efficiency program and we are operating at high %O2 levels around 4-5% , we are also having orifice plate flow measurement on the fuel gas line. the emissions are still within the limits of local regulations but we want to operate the heaters at low %O2 may be 2-3% , having a analyzer which means are you referring to Gas chromatograph which would give the Composition and heating value ? the GC has high maintenance and also it isn’t fast enough to give real time data which can be used to control. so hence we were looking at the other ways. the reason why we can operated at low O2 is high variability of fuel gases.
