DESIGN OF CENTRIFUGAL COMPRESSOR IMPELLER FOR OPTIMAL EFFICIENCY

A new methodology is proposed to use comprehensive up-to-date commercial software tools for Heat Exchanger Network (HEN) reliability modelling and optimisation. The idea behind this proposal that apply the combination of specific HEN optimisation packages has several advantages over commonly used approach. There a variety features need be taken into account choose right tool. design significant impact on issues should considered. are many related - robustness, type welding, increment maximum mechanical resistance, manufacturing costs, reduction lost opportunity costs caused by exchanger outages, troubleshooting heating problems operators etc. Fouling analysed as it maintenance issues. Up 30 % decrease can achieved annually applying advanced results determining heat failure causes. These analyses include investigation causes, prediction future probabilities failures, cleaning planning scheduling calculation maintainability. Keywords: exchangers, optimisation, network, oil refinery, recovery systems.
