Simulation and optimization Distillation Tower in Phases 2 and 3 of South Pars

Distillation process is the commonest process for separating material and on the other hand it is the most expensive unit in terms of energy consumption. This process has a significant proportion of energy in the industry. Thus, according to the uncontrolled increase in consuming energy as well as global energy prices, the attempts to find ways to save energy in the distillation process is of very importance. This study investigates energy recovery for condenser of the stabilization tower (South Pars Phases 2 and 3) by using thermal integration.The tower condenser is originally air conditioner that consumes 3 megawatts electrical power for the overhead vapor condensation to the temperature of 55 ° C Per hour. The cost of the production of this amount of energy is considerable. Based on the thermal integration, the amount of feeding energy due to its low temperature is suitable for condensing and even one can improve the condensing temperature to 25 ° C. In this paper, by replacing heat exchanger with current air conditioner and by using food as condensation factor, excellent results were obtained. In case of using the integration, 3942 GJ electric power will be saved annually, the current air conditioner will be remove from the process and a good profit will obtained for this operating Unit through reducing the cost of electricity supply of condenser.
