Control of Volatile Organic Compounds Emissions from Manufacturing

condenser sizes are not necessarily linear. Therefore, we assumed that
the costs varied exponentially with the ratio of the emission factors
between the costs at 3.09 kg/Mg and 0.2 kg/Mg. The exponents were
calculated using the following equation:
(15) exp =
where: AC1 = the relevant annualized costs associated with ER1
AC2 = the relevant annualized costs associated with ER2
ER1 = 3.09 kg VOC/Mg product
ERE = 0.2 kg VOC/Mg product
The annualized costs were grouped as follows: (a) capital related
(maintenance, taxes, insurance, administration, and capital recovery
charge, (b) labor, (c) pumping electricity and make-up coolant, and (d)
refrigeration coolant. Table F-7 summarizes the costs and resulting
exponents.
Using the exponents from Table F-7 and the costs from Table F-6,
the following cost-effectiveness equation was developed:
where: (23,870 - 8,170) 0.3 = Incremental maintenance,
taxes, insurance, etc.
