NOx Emissions from Cement Mfg - US Environmental Protection ...

The total capital cost is the sum of the purchased equipment
costs, direct installation costs, indirect installation costs,
and contingency costs. The purchased equipment costs (PECs) used
in this chapter for each control technology are based on cost
information provided by vendors or from data provided by existing
facilities. Table 6-2 provides a list of various cost elements
included in the capital costs. Where installation costs were not
provided by vendors, direct and indirect installation costs were
developed using the factors 45 and 33 percent, respectively, of
PEC, per guidelines in the EPA OAQPS Control Cost Manual.2 A
contingency factor of 20 percent was added to the vendor costs in
all cases to cover contingencies as listed in Table 6-2. The
capital costs of in-combustion approaches such as low NOx burner
and postcombustion approaches such as selective noncatalytic
reduction are related to the clinker production capacity of the
kiln as well as the energy requirement of the kiln per unit
amount of clinker production.
