Tenn. Comp. R. & Regs. 1200-03-16-.32 - AMMONIUM SULFATE MANUFACTURE
"Ammonium sulfate dryer" means a unit or vessel into which ammonium sulfate is charged for the purpose of reducing the moisture content of the product using a heated gas stream. The unit includes foundations, superstructure, material charger systems, exhaust systems, and integral control systems and instrumentation.
"Ammonium sulfate feed material streams" means the sulfuric acid feed stream to the reactor/crystallizer for synthetic and coke oven by-product ammonium sulfate manufacturing plants; and means the total or combined feed streams (the oximation ammonium sulfate stream and the rearrangement reaction ammonium sulfate stream) to the crystallizer stage, prior to any recycle streams.
"Ammonium sulfate manufacturing plant" means any plant which produces ammonium sulfate.
"Caprolactam by-product ammonium sulfate manufacturing plant" means any plant which produces ammonium sulfate as a by-product from process streams generated during caprolactam manufacture.
"Coke oven by-product ammonium sulfate manufacturing plant" means any plant which produces ammonium sulfate by reacting sulfuric acid with ammonia recovered as a byproduct from the manufacture of coke.
"Synthetic ammonium sulfate manufacturing plant" means any plant which produces ammonium sulfate by direct combination of ammonia and sulfuric acid.
On or after the date on which the performance test required to be conducted by 1200-3-16 - .01(5) is completed, no owner or operator of an ammonium sulfate dryer subject to the provisions of this rule shall cause to be discharged into the atmosphere, from any ammonium sulfate dryer, particulate matter at an emission rate exceeding 0.15 kilogram of particulate per megagram of ammonium sulfate produced (0.30 pound of particulate per ton of ammonium sulfate produced) and exhaust gases with greater than 15 percent opacity.
P = A x B x C x 0. 0808 where:
P = Ammonium sulfate production rate in megagrams per hour.
A = Sulfuric acid flow rate to the reactor/crystallizer in liters per minute averaged over the time period taken to conduct the run.
B = Acid density (a function of acid strength and temperature) in grams per cubic centimeter.
C = Percent acid strength in decimal form.
0.0808 = Physical constant for conversion of time, volume, and mass units.
P = D*E*F*(6.0x10-5)
P = Production rate of caprolactam by-product ammonium sulfate in megagrams per hour.
D = Total combined feed stream flow rate to the ammonium sulfate crystallizer before the point where any recycle streams enter the stream in liters per minute averaged over the time period taken to conduct the test run.
E = Density of the process stream solution in grams per liter.
F = Percent mass of ammonium sulfate in the process solution in decimal form. (6.0 x 10-5) = Physical constant for conversion of time and mass units.
R = E/P
