Note:
The requirements of subdivisions (c) through (g) of this section apply to process vents on hazardous waste recycling units previously exempt under section 371.1(g)(3)(i) of this Title. Other exemptions under sections 371.1(e) and 373-3.1(a) of this Title are not affected by these requirements.
As used in this section, all terms shall have the meaning given them in section 373-2.27(b) of this Part, the ECL and Parts 370 through 374 of this Title.
HT = K × (summation (i=1 to n)(C i × Hi))
where:
HT = Net heating value of the sample, MJ/scm; where the net enthalpy per mole of offgas is based on combustion at 25°C and 760 mm Hg, but the standard temperature for determining the volume corresponding to 1 mol is 20°C;
K = Constant, 1.74 ×- 10-7 (1/ppm) (g mol/scm) (MJ/kcal) where standard temperature for (g mol/scm) is 20°C;
Ci = Concentration of sample component i in ppm on a wet basis, as measured for organics by Reference Method 18 in 40 CFR part 60 (see section 370.1[e] of this Title) and measured for hydrogen and carbon monoxide by ASTM D 1946-82 (incorporated by reference as specified in section 370.1[e] of this Title); and
Hi = Net heat of combustion of sample component i, kcal/g mol at 25°C and 760 mm Hg. The heats of combustion may be determined using ASTM D 2382-83 (incorporated by reference as specified in section 370.1[e] of this Title) if published values are not available or cannot be calculated.
Log10(Vmax) = (HT + 28.8)/31.7
where:
HT = The net heating value as determined in subparagraph (ii) of this paragraph.
28.8 = Constant.
31.7 = Constant.
Vmax = 8.706 + 0.7084 (HT)
where:
8.706 = Constant.
0.7084 = Constant.
HT = The net heating value as determined in subparagraph (ii) of this paragraph.
Eh = Q2sd × (summation {i=1 to n}(C1MWi)) × (0.0416) × (10-6)
where:
Eh = Total organic mass flow rate, kg/h;
Q2sd = Volumetric flow rate of gases entering or exiting control device, as determined by Method 2, dscm/h;
n = Number of organic compounds in the vent gas;
Ci = Organic concentration in ppm, dry basis, of compound i in the vent gas, as determined by Method 18;
MWi = Molecular weight of organic compound i in the vent gas, kg/kg-mol;
0.0416 = Conversion factor for molar volume, kg-mol/m3 (@ 293 K and 760 mm Hg);
10-6 = Conversion from ppm, ppm-1.
Eh = (Q)(C)(MW)(0.0416)(10-6)
where:
Eh = Total organic mass flow rate, kg/h;
Q = Volumetric flow rate of gases entering or exiting control device as determined by Method 2, dscm/h;
C = Organic concentration in ppm, dry basis, as determined by Method 25A;
MW = Molecular weight of propane, 44;
0.0416 = Conversion factor for molar volume, kg mol/m3 (at 293 K and 760 mm Hg);
10-6 = Conversion from ppm.
EA = (Eh)(H)
where:
EA = Total organic mass emission rate, kg/y;
Eh = Total organic mass flow rate for the process vent, kg/h;
H = Total annual hours of operations for the affected unit, h.
