Abstract
In chemical plants, Heat exchangers contribute with main fraction in
heat recovery and energy saving. Heat exchanger network design is main
optimization problem in chemical plant design and optimization. Optimal
heat exchanger network synthesis has essential impact on cost saving by
reducing total annual cost which include fixed cost and operating cost.
Optimum design contributes in environment protection by reducing hot
duties. this mean reduction in fuel combustion leading to reduction in
pollutant emission into the environment.
