Chapter 8. Estimation of Manufacturing Costs
• It is necessary to quantify the cost of manufacture of a chemical process.
• The primary components of the cost of manufacture are raw materials, utilities, and waste treatment.
The costs associated with the day-to-day operation of a chemical plant must be estimated before the economic feasibility of a proposed process can be assessed. This chapter introduces the important factors affecting the manufacturing cost and provides methods to estimate each factor. In order to estimate the manufacturing cost, process information provided on the PFD, an estimate of the fixed capital investment, and an estimate of the number of operators required to operate the plant are all needed. ...
