Linnhoff method

NettetThe pinch method consists of two steps. In the first step the maximum energy recovery in the system should be calculated which in turn reduces the external energy needed to a minimum level. Consider the process streams and it temperatures in table 1. Figure 3 shows the process streams and the temperature intervals for the plant. Nettet1. jun. 2008 · The core elements of this method are the calculation of energy and cost targets for the process, which inform the minimum energy consumption and the minimum cost of the HEN required to reach this minimum, and a systematic methodology for the design of a HEN that actually meets those targets is based on the use of simplified …

NettetPinch technology or pinch analysis is a method used to target energy in chemical process by calculating thermodynamically feasible target. It was developed by teams led by Professor Bodo Linnhoff at University of Manchester (UK) in 1980’s. als In France, Jean-Paul Gourlia also contributed to popularize this approach with several reference papers.

One also can estimate the heat exchange area required'. In late 1977, Ph.D. student Bodo Linnhoff under the supervision of Dr John Flower at the University of Leeds showed the existence in many processes of a heat integration bottleneck, ‘the pinch’, w…
