Estimate the cost of operating labor (C_OL), the cost of utilities (C_UT), and the cost of manufacturing (COM_d) for the ethylene oxide process given in Project B.6 of Appendix B. You must do Problem 7.26 in order to estimate COM_d.

Problem 7.26

Determine the bare module, total module, and grassroots cost of the following:

B.6 ETHYLENE OXIDE PRODUCTION, UNIT 700 Ethylene oxide is a chemical used to make ethylene glycol (the primary ingredient in antifreeze). It is also used to make polyethylene oxide, and both the low-molecular-weight and high-molecular-weight polymers have many applications including as detergent additives. Because ethylene oxide is so reactive, it has many other uses as a reactant. However, because of its reactivity, danger of explosion, and toxicity, it is rarely shipped outside the manufacturing facility but instead is often pumped directly to a nearby consumer.
