Based upon the following data for the reactors, compressors/expanders, and distillation columns of a plant to produce 1,500 metric ton/day of methanol with an operating factor of 0.95 , estimate by using Method 1 (order-of-magnitude estimate) the total capital investment. The two methanol reactors are of the shell-and-tube type. The plant will be constructed outdoors and is a major addition to existing facilities. Use a CE cost index of 600 .
