= 0.0126 for coke
%CO2 is the carbon dioxide concentration, percent dry basis
NR 440.24 NoteNote: It is necessary in some cases to convert measured concentration units to other units for these calculations. Use the following table for such conversions:
NR 440.24(5)(e)(e) For the purpose of reports under s. NR 440.07 (3), periods of excess emissions shall be all 3-hour periods (or the arithmetic average of 3 consecutive 1-hour periods) during which the integrated average sulfur dioxide emissions exceed the applicable standards under sub. (3).
NR 440.24(6)(6)Test methods and procedures.
NR 440.24(6)(a)(a) In conducting the performance tests required in s. NR 440.08, the owner or operator shall use as reference methods and procedures the test methods in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, or other methods and procedures as specified in this subsection, except as provided in s. NR 440.08 (2). Acceptable alternative methods and procedures are given in par. (c).
NR 440.24(6)(b)(b) The owner or operator shall determine compliance with the SO2 acid mist, and visible emission standards in subs. (4) and (5) as follows:
NR 440.24(6)(b)1.1. The emission rate (E) of acid mist or SO2 shall be computed for each run using the following equation:
E = (CQsd)/(PK)
where:
E is the emission rate of acid mist or SO2 kg/metric ton (lb/ton) of 100% H2SO4 produced
C is the concentration of acid mist or SO2, g/dscm (lb/dscf)
Qsd is the volumetric flow rate of the effluent gas, dscm/hr (dscf/hr)
P is the production rate of 100% H2SO4, metric ton/hr (ton/hr)
K is the conversion factor, 1000 g/kg (1.0 lb/lb)
NR 440.24(6)(b)2.2. Method 8 shall be used to determine the acid mist and SO2 concentrations (C’s) and the volumetric flow rate (Qsd) of the effluent gas. The moisture content may be considered to be zero. The sampling time and sample volume for each run shall be at least 60 minutes and 1.15 dscm (40.6 dscf).
NR 440.24(6)(b)3.3. Suitable methods shall be used to determine the production rate (P) of 100% H2SO4 for each run. Material balance over the production system shall be used to confirm the production rate.
NR 440.24(6)(b)4.4. Method 9 and the procedures in s. NR 440.11 shall be used to determine opacity.
NR 440.24(6)(c)(c) The owner or operator may use the following as alternatives to the reference methods and procedures specified in this subsection:
NR 440.24(6)(c)1.1. If a source processes elemental sulfur or an ore that contains elemental sulfur and uses air to supply oxygen, the following procedure may be used instead of determining the volumetric flow rate and production rate:
NR 440.24(6)(c)1.a.a. The integrated technique of Method 3 is used to determine the O2 concentration and, if required, CO2 concentration.
NR 440.24(6)(c)1.b.b. The SO2 or acid mist emission rate is calculated as described in sub. (5) (d), substituting the acid mist concentration for Cs as appropriate.
