Heat exchanger network (HEN) is an effective method to recover the heat energy used in process plants. However, the energy integration causes to the interactions among process units and some cases there are variation in target temperature may cause the process more difficult to maintain the target temperature. Therefore, in order to achieve maximum energy recovery and to track target temperature at changing desirable values, the resilient heat exchangers that can tolerate the varied target temperatures are indeed necessary. This research, the resilient heat exchanger network design procedure provided by Wongsri (1990) is extended cover the design resilient network in case target temperature variation. We presents procedure for design control structure of heat exchanger network using heuristic approach such as Pinch Design, Match Patterns, Disturbance Directedness, Bypass Setting, Split Ratio and Selector Switch Setting to solve 3 heat exchanger network problems. It has been shown that our procedure is able to maintain target temperatures at specified values. Furthermore, our design does not violate maximum energy recovery. The heat exchanger network with control structures are programmed using HYSYS for control structure performance tests.

An effective method to recover the energy from production process plants is heat exchanger network (HEN). However, the energy integration can cause interactions to the other units in process and variation input temperature because environment or product specification that cause the problem to maintain the target temperature and achieve maximum energy recovery. This research, the resilient heat exchanger network design method to dispose of disturbance provide by Wongsri (1990) is modified in case input temperature and flow rate variation. This procedure is presented for design control structure of heat exchanger network using heuristic approach such as match patterns, pinch design, disturbance propagation, bypass setting and selector switch setting to solve 3 examples for heat exchanger network problems. The heat exchanger network with control structures are programmed by simulation in HYSYS for evaluation performance of control structure.

Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing. house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 25 (thesis year 1980) a total of 10,308 theses titles from 27 Canadian and 214 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 25 reports theses submitted in 1980, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Design and Operation of heat Exchangers and Their Networks presents a comprehensive and detailed analysis on the thermal design methods for the most common types of heat exchangers, with a focus on their networks, simulation procedures for their operations, and measurement of their thermal performances. The book addresses the fundamental theories and principles of heat transfer performance of heat exchangers and their applications and then applies them to the use of modern computing technology. Topics discussed include cell methods for condensers and evaporators, dispersion models for heat exchangers, experimental methods for the evaluation of heat exchanger performance, and thermal calculation algorithms for multi-stream heat exchangers and heat exchanger networks. Includes MATLAB codes to illustrate how the technologies and methods discussed can be easily applied and developed. Analyses a range of different models, applications, and case studies in order to reveal more advanced solutions for industrial applications. Maintains a strong focus on the fundamental theories and principles of the heat transfer performance of heat exchangers and their applications for complex flow arrangement.
