Heat and Power Systems Design

Abstract

The selection of heat and power systems usually does not include a thorough analysis of the process heating, cooling and power requirements. In most cases, these process requirements are accepted as specifications before heat and power systems are selected and designed. In this article we describe how Process Integration using Pinch Technology can be used to understand and achieve the minimum process heating and cooling requirements and to match heat and power systems to these needs to achieve overall least cost solutions. The basic concepts of Pinch Technology are developed and explained in the context of how a heat and power scheme is selected for a brewery. A second example involving a chemical processing plant shows how the process itself may be altered to design a non-obvious, cost-effective cogeneration system.
