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}

It involves the recovery of waste heat to pre-heat spray dryer inlet air. It is estimated that the adoption of this technology within the UK will lead to energy savings worth £1.5M/year by 1990.&lt;/p&gt;&lt;p&gt;The project at BIP demonstrates the use of a heat pipe exchanger to recover the heat from a boiler exhaust in order to pre-heat the inlet air. Other projects in the package are at Clayton Aniline Ltd and ABM chemicals Ltd. In these the heat is recovered from the spray dyrer exhaust using a run-around coil and a glass tube heat exchanger respectively.&lt;/p&gt;&lt;p&gt;The performance of the system at BIP was independently monitored by the Harwell Laboratory, and this report details the performance of the exchanger and the resulting energy and cost savings at the spray dryer.&lt;/p&gt;&lt;p&gt;The total cost of the installation was £22,000, of which £5500 was funded by the Energy Efficiency Office. The heat recovery system has resulted in a 27% reduction in the specific energy consumption of the spray dryer. For BIP in 1983, this was worth £11,300/year giving a simple payback period of 1.9 years.&lt;/p&gt;&lt;p&gt;The savings associated with this type of heat recovery system are dependent upon a number of factors including: &lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;span&gt;1.&lt;/span&gt;&lt;span&gt;&lt;p&gt;(i) The quantity of available flue gas—at the maximum flue gas flow-rate, the savings to BIP would be worth £14,500/year, giving a project payback of 1.5 years;&lt;/p&gt;&lt;/span&gt;&lt;/li&gt;&lt;li&gt;&lt;span&gt;2.&lt;/span&gt;&lt;span&gt;&lt;p&gt;(ii) The frequency of operation of the spray dryer—BIP operated their dryer for 3677 h in 1983. Assuming a notional 6000 h, the savings, at maximum flue gas availability would be worth £22,000 with a payback of one year;&lt;/p&gt;&lt;/span&gt;&lt;/li&gt;&lt;li&gt;&lt;span&gt;3.&lt;/span&gt;&lt;span&gt;&lt;p&gt;(iii) The mode of operation—BIP installed the exchanger in a co-current flow mode. In the more efficient counter-current orientation, savings worth £31,000 could have been achieved giving a payback period of just eight months. BIP installed the exchanger in a cocurrent mode because of the simplicity of installation.&lt;/p&gt;&lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;A number of operational factors associated with the heat exchanger have been identified in the course of this project: &lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;span&gt;1.&lt;/span&gt;&lt;span&gt;&lt;p&gt;(i) It is essential to ensure that the heat pipe heat exchanger cannot be subjected to temperatures in excess of the design limit. During the course of this project this led to tube fracture which has necessitated the replacement of the exchanger unit:&lt;/p&gt;&lt;/span&gt;&lt;/li&gt;&lt;li&gt;&lt;span&gt;2.&lt;/span&gt;&lt;span&gt;&lt;p&gt;(ii) To enable good efficiency to be maintained, it is essential that provision be made to allow for routine cleaning of the heat exchanger.&lt;/p&gt;&lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;In addition, to maximise the cost savings, dryer operation should be as efficient as possible.
