Cleaning Schedule Optimization of Heat Exchanger Networks Using Particle Swarm Optimization
Oil refinery is one of industries that require huge energy consumption. The today technology advance requires energy saving. Heat integration is a method used to minimize the energy comsumption though the implementation of Heat Exchanger Network (HEN). CPT is one of types of Heat Exchanger Network (HEN) that functions to recover the heat in the flow of product or waste. HEN comprises a number o...
متن کاملSynthesis of Heat Exchanger Network Subject to Fouling and Ageing with the Cleaning Schedule Optimized
In order to reduce extra capital and energy cost caused by fouling and ageing, this paper presents a new methodology for synthesizing heat exchanger network (HEN) with the cleaning schedule optimized. Two cleaning methods with different cleaning efficiency are used to remove fouling and ageing, so the cleaning mode has to be selected along with an optimal cleaning schedule. The process is imple...
متن کاملHeat Exchanger Fouling and Cleaning: Fundamentals and Applications
ESDU International of London, UK has recently published a ‘User Guide’ [1] on fouling in heat exchange systems using seawater as the coolant. Developed over a period of eighteen months in close collaboration with a team of oil refiners, heat transfer equipment and services suppliers and universities, with valuable input from the power industry, the User Guide is a practical guide to the current...
متن کاملAn Minlp Formulation for Scheduling the Cleaning of Heat Exchanger Networks Subject to Fouling and Ageing
Fouling is an age-old problem in many process industries. It is responsible for large energy and throughput losses, resulting in financial penalties and negative environmental impact. One effective mitigation strategy is the regular cleaning of fouled heat transfer devices. Optimization tools can be used to schedule the timing of cleaning actions in order to minimize the cost of fouling and imp...
متن کاملModel based approach to synthesize spare-supported cleaning schedules for existing heat exchanger networks
Almost every modern chemical process is equipped with a heat-exchanger network (HEN) for optimal energy recovery. However, as time goes on after startup, fouling on the heat-transfer surface in an industrial environment is unavoidable. If the heat exchangers in an operating plant are not cleaned regularly, the targeted thermal efficiency of HEN can only be sustained for a short period of time. ...
