This paper presents an analytical model for on-chip heat dissipation in VLSI design. A chip and its test configuration also are developed to verify modeling results. The model and chip are representative of general IC packages. Our research shows that circuit location on a chip determines its default offset temperature and heat transport properties, which must be considered for accurate predict...

This paper addresses the internal heat integration to the pressure-swing distillation process used in the separation of binary azeotrope mixture. A general procedure is suggested and illustrated through the separation of an binary mixture, which forms pressure-sensitive minimum-boiling azeotropes. Comparisons are made between the conventional and the internally heat integration processes. It is...

The synthesis problems of non‒isothermal water networks have received considerable attention throughout academia and industry over the last two decades because of the importance of simultaneously minimising water and energy consumption [1]. Most papers have addressed this issue only by considering heat integration between hot and cold water streams. In this study, the scope of heat integration ...

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

Process integration consists of numerous techniques that allow engineers to evaluate entire processes or sites, rather than focus on individual unit operations. It includes hierarchical design methods, knowledge-based systems, numerical and graphical techniques, and pinch analysis (1, 2). In the area of energy effi ciency, pinch methods dominate. Indeed, the terms pinch analysis and process int...

This paper presents a new approach for the simultaneous synthesis and optimization of heat integrated water networks. A new superstructure for heat exchanger network (HEN) synthesis is proposed. The procedure is based onmixed integer non-linearmathematical programming (MINLP). Four relevant examples are presented to illustrate various aspects of the proposed approach. © 2008 Elsevier Ltd.

Industrial sectors are improving their energy efficiency and increasing share of renewables for heating cooling demands by using lower emission technologies. One specific approach to help achieve these targets is the integration heat pumps (HPs) in industrial processes. However, due temporal variation requirements non-continuous processes, HP challenging. In this paper, a structured method desi...

−Dividing wall columns, capable of reducing the energy required for the separation of ternary mixtures, were explored for the energy-efficient integration of debutanization and deisobutanization. A new practical approach to the design and optimization of dividing wall columns was used to optimize dividing wall columns. A conventional dividing wall column and a multi-effect prefractionator arran...
