NR 440.26(7)(b)1.1. The emission rate (E) of PM shall be computed for each run using the following equation: where:
E is the emission rate of PM, kg/Mg (lb/ton) of coke burn-off
cs is the concentration of PM, g/dscm (gr/dscf)
Qsd is the volumetric flow rate of exhaust gas, dscm/hr (dscf/hr)
Rc is the coke burn-off rate, Mg/hr (ton/hr) coke
K is a conversion factor, 1,000 g/kg (7000 gr/lb)
NR 440.26(7)(b)2.2. Method 5B or 5F shall be used to determine particulate matter emissions and associated moisture content from affected facilities without wet FGD systems; only Method 5B shall be used after wet FGD systems. The sampling time for each run shall be at least 60 minutes and the sampling time for each run shall be at least 0.015 dscm/min (0.53 dscf/min) except that shorter sampling times may be approved by the department when process variables or other factors preclude sampling for at least 60 minutes. NR 440.26(7)(b)3.3. The coke burn-off rate (Rc) shall be computed for each run using the following equation: where:
Rc is the coke burn-off rate, Mg/hr (ton/hr)
Qr is the volumetric flow rate of exhaust gas from catalyst regenerator before entering the emission control system, dscm/min (dscf/min)
Qa is the volumetric flow rate of air to FCCU regenerator, as determined from the fluid catalytic cracking unit control room instrumentation, dscm/min (dscf/min)
%CO2 is the carbon dioxide concentration, percent by volume (dry basis)
%CO is the carbon monoxide concentration, percent by volume (dry basis)
%O2 is the oxygen concentration, percent by volume (dry basis)
K1 is the material balance and conversion factor, 2.982 x 10-4 (Mg-min)/hr-dscm-%) [9.31 x 10-6 (ton-min)/(hr-dscf-%)]
K2 is the material balance and conversion factor, 2.088 x 10-3 (Mg-min)/(hr-dscm-%) [6.52 x 10-5 (ton-min)/(hr-dscf-%)]
K3 is the material balance and conversion factor, 9.94 x 10-5 (Mg-min)/(hr-dscm-%) [3.1 x 10-6 (ton-min)/(hr-dscf-%)]
NR 440.26(7)(b)3.b.b. The emission correction factor, integrated sampling and analysis procedure of Method 3B of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), shall be used to determine CO2, CO and O2 concentrations. NR 440.26(7)(c)(c) If auxiliary liquid or solid fossil fuels are burned in an incinerator-waste heat boiler, the owner or operator shall determine the emission rate of PM permitted in sub. (3) (b) as follows: NR 440.26(7)(c)1.1. The allowable emission rate (Es) of PM shall be computed for each run using the following equation: where:
