Linnhoff method
In 1971, Ed Hohmann stated in his PhD that 'one can compute the least amount of hot and cold utilities required for a process without knowing the heat exchanger network that could accomplish it. 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… Nettet@misc{etde_5560546, title = {The pinch design method for heat exchanger networks} author = {Linnhoff, B, and Hindmarsh, E} abstractNote = {A novel method is presented for the design of heat exchanger networks.

Nettet13. apr. 2024 · Process integration based on Pinch methods began in the 1970s, and the inclusion of heat pumps within the analysis was first presented by Linnhoff and Townsend in 1983 [ 10 ]. In 1993, Linhoff and Townsend brought these Pinch analysis methods together in the first iteration of the Total Site Heat Integration concept [ 11 ]. Nettet1. jan. 1979 · Abstract. Over the past ten years or so, various systematic methods have been described in the literature for the preliminary design of heat exchanger networks. These methods have bee applied to simplified example problems but there is little evidence of applications in industry. Hopefully this paper will show the reason for this …
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.
