NR 440.55(5) (5) Test methods and procedures.

NR 440.55(5)(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 s. NR 440.08 (2).

NR 440.55(5)(b) (b) The owner or operator shall determine compliance with the particulate matter standards in sub. (3) as follows:

NR 440.55(5)(b)1. 1. The emission rate (E) of particulate matter shall be computed for each run using the following equation:

where:

E is the emission rate of particulate matter, kg/Mg (lb/ton) of ammonium sulfate produced

cs is the concentration of particulate matter, g/dscm (g/dscf)

Qsd is the volumetric flow rate of effluent gas, dscm/hr (dscf/hr)

P is the production rate of ammonium sulfate, Mg/hr (ton/hr)

K is the conversion factor, 1000 g/kg (453.6 g/lb)

NR 440.55(5)(b)2. 2. Method 5 shall be used to determine the particulate matter concentration

and volumetric flow rate (Qsd) of the effluent gas. The sampling time and sample volume for each run shall be at least 60 minutes and 1.50 dscm (53 dscf).

NR 440.55(5)(b)3. 3. Direct measurement using product weigh scales, or the results of computations using a material balance, shall be used to determine the rate (P) of the ammonium sulfate production. If production rate is determined by material balance, the following equations shall be used:

NR 440.55(5)(b)3.a. a. For synthetic and coke oven by-product ammonium sulfate plants:

P = ABCK¢

where:

A is the sulfuric acid flow rate to the reactor/crystallizer averaged over the time period taken to conduct the run, liter/min

B is the acid density (a function of acid strength and temperature), g/cc

C is the acid strength, decimal fraction

K¢ is the conversion factor, 0.0808 (Mg-min-cc)/(g-hr-liter) [0.0891 (ton- min-cc)/(g-hr-liter)]

NR 440.55(5)(b)3.b. b. For caprolactam by-product ammonium sulfate plants:

P = DEFK²

where:

D is the total combined feed stream flow rate to the ammonium crystallizer before the point where any recycle streams enter the stream averaged over the time period taken to conduct the test run, liter/min

E is the density of the process stream solution, g/liter

F is the percent mass of ammonium sulfate in the process solution, decimal fraction

K² is the conversion factor, 6.0 ×10-5 (Mg-min)/(g-hr) [6.614 × 10-5 (ton-min)/g-hr)]

NR 440.55(5)(b)4. 4. Method 9 and the procedures in s. NR 440.11 shall be used to determine the opacity.
