retrofit of heat exchanger networks considering existing structure: a new targeting procedure
نویسندگان
چکیده
a new retrofit targeting procedure, based on pinch technology has been developed. the new procedure considers existing structure of a given network and finds the most compatible configuration with the network. to achieve this aim, the procedure uses a linear programming technique that maximize the compatibility. good compatibility between old and new networks helps to make the best use of capital in retrofit projects. the procedure has been tested by doing two case studies, in which the results compared to other established methods, and realized significant improvement.

متن کاملMultiple Modifications in Stepwise Retrofit of Heat Exchanger Networks
This work considers improving the heat recovery of an existing heat exchanger network (HEN) while minimizing the total annualized cost of the retrofit design. The focus is on stepwise approaches that generate, starting from the base case network, a candidate retrofit HEN at each step in order to sequentially retrofit the HEN topology while permitting user intervention during the resolution proc...
متن کاملArea Energy and Throughput Targeting in Debottlenecking of Heat Exchanger Networks with Decomposition Approach
For energy saving retrofit projects, its economics are usually evaluated in terms of capital investment and payback time. The capital investment is in direct relation to the total heat recovery area of the network and the payback time factor is base on both the area and the energy savings. The debottlenecking is an increased throughput, which can be profitable in economic sense. The combination...
متن کاملMINLP synthesis of heat exchanger networks considering pressure drop effects
Considerable research effort has been reported in both Pinch Technology and MINLP techniques for the synthesis of heat exchanger networks. However, most of the design procedures assume constant stream heat transfer coefficients. A problem arises because there is no guarantee that the values of the coefficients assumed during network synthesis are the same as those actually achieved in detailed ...
