Linnhoff method

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. NettetAbstract. A thermodynamically orientated method is presented for the synthesis of heat exchanger networks. With this method, the problem is solved in two stages. In the first stage, preliminary networks are generated which give maximum heat recovery.

Nettet25. jun. 2024 · A common methodology is to replace or swap customers between sub-tours taking capacity constraints into account. Popular improvement methods can be found in Lin (1965) and Or (1976). Metaheuristics can be thought of as top-level strategies which guide local improvement operators to find a global solution. Nettet2. des. 2024 · The characteristic of this model is that it changes the matching mode of heat exchangers by setting the number of nodes on streams to quantify the positions of heat exchangers. The proposed nodes-based model has more flexibility in generating and eliminating the heat exchangers and strong ductility in exploring the solution domain.
