The minimal total annual cost problem is illustrated with two realistic chemical systems: hydrolysis of methyl lactate and esterification of formic acid. The effect of design and operating variables on total annual cost is investigated. The optimization results suggest that a reflux policy which maintains constant distillate composition can provide nearly optimal operation. The column should be designed with an adequate number of stages so that the batch capacity improvement by further increasing the number of stages is insignificant. Vapor boilup rate should be specified to make the best use of the available operating time, and the optimal vapor boilup rate is primarily affected by the catalyst loading. The insight into the effect of process design variables on design performance is used to develop an efficient algorithm for determining simultaneously the optimal column design and operating policy. ? 2015 American Chemical Society. |
