摘要：
In order to investigate the comprehensive effects of heat pump installation on energy saving and CO2 emission reduction in heat exchanger network (HEN) retrofit, a step-by-step multi-objective optimization model with combination of multiple strategies was proposed for HEN retrofit, in which the objective was to minimize the annual HEN retrofit cost and newly increased CO2 emissions. A HEN retrofit problem of a benzol-ketone dewaxing unit was taken to illustrate the effectiveness of the proposed method. The Pareto fronts that represented the trade-offs between economy and CO2 emission were presented. The location of heat pump installation in HEN was discussed. For the three retrofit strategies, the effects of economy, CO2 emission and energy saving were compared and analyzed. The proposed method would provide theoretical fundamentals for formulating schemes of energy conservation and CO2 emission control in process industries. ©All Rights Reserved
