【Abstract】 By analyizing the energy utilization of the simple fractionator, it was pointed out that, the energy consumption, as the driving force of separation processes, depends mainly on the reflux ratio and the temp. drop across the whole towcr. The fractionator can be dcvided into three parts, namely, conversion, utilization and recovery of energy. After the optimization of the three parts respectively and the final integrated coordination of energy values at the linking points, an optimizing program for the simple fractionator was worked out. Practices showed that, the reflux ratio obtained was different from that ob- tained by traditional optimization, and the annual cost was reduced by 50%. The program is available for the development of integrated energy optimization of partial sys- tems.更多还原
