摘要/Abstract

摘要： 基于异丁烯提纯反应精馏的特点，设计了塔顶蒸汽压缩式的热泵节能流程。利用Aspen Plus软件对全流程进行模拟，并提出了针对部分冷凝流程的热泵精馏模拟策略。从火用分析和技术经济的角度，全面对其进行能耗和经济性分析评价。案例研究结果表明：采用热泵节能技术的反应精馏过程，当压缩比为1.6时，能耗及总费用最低；且与常规反应精馏过程相比，采用热泵节能技术后单位产品能耗降低约87.5%，热力学效率提高32.7百分点，年操作费用下降64.4%，热泵投资回收期为1.5年。

Abstract: Based on the characteristics of isobutylene purification reaction distillation, a steam compression heat pump energy saving process was designed. In this work, the whole isobutylene purification reaction distillation process simulated by Aspen Plus, and the simulation strategy of heat pump distillation for partial condensation process was proposed. From the point of view of exergy analysis and technical economy, energy consumption and economical efficiency were evaluated comprehensively. A case study showed that the reaction distillation process using heat pump energy saving technology was compared with the conventional process. When the compression ratio was 1.6, the energy consumption per unit product decreased by 87.5%, effective energy efficiency increased by 32.7%, annual operating cost decreased by 64.4%, project investment payback period was 1.5 years.

Key words: heat pump, reactive distillation, simulation, energy analysis, economic analysis
