The heat integration concept [1] attempts to integrate the heating and cooling demands of a column within the heat network of the overall process. In case of stand-alone unit or severe restrictions on integrability of distillation column, the realization of heat pump assisted distillation seems to be one of the most promising energy saving techniques. Because of its less energy demand, the heat pump assisted distillation reduces the operating cost and occasionally can compensate the additional capital expenses of compressor. Based on the <em>COP</em> and energy costs, simple expressions are developed for preliminary economic analysis and design of heat pump assisted distillation. A design strategy is proposed for selecting the most economical distillation system based on the energy cost factor and the estimated payback time of excess capital. The strategy is demonstrated by two examples.</p></div>","PeriodicalId":100786,"journal":{"name":"Journal of Heat Recovery Systems","volume":"6 6","pages":"Pages 469-476"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0198-7593(86)90039-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75247327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, two power plants produce electricity from it. The oldest, CP I, as been on line for more than a decade; CP II recently started producing at half capacity, and CP III is scheduled to come on line soon. In this work we investigate the mass and heat reserves, the corresponding deliverability, and the expected quality of the heat delivered, in relation to CP I. We also inquire into the likely effect of the planned production of the CP II and CP III power plants on the future performance of CP I. The investigation is accomplished via numerical simulation. Our results indicate that the reserves of mass and heat in the layers that feed CP I are adequate for a thirty year economic life of the plant, that the quality of the produced heat will decline with time to about 85% of its peak value, and that the main effect of production by CP II and CP III is to enhance recharge by cool water of the zone that feeds CP I.</p></div>","PeriodicalId":100786,"journal":{"name":"Journal of Heat Recovery Systems","volume":"6 6","pages":"Pages 451-463"},"PeriodicalIF":0.0,"publicationDate":"1986-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0198-7593(86)90037-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90972646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
