Abstract

Due to the separation of light and heavy phases in the distillation towers of the petrochemical industries, some hydrocarbons have been burned in the flare. Combustion of these gases produces toxic and dangerous gases by the flare and vent into the environment. In the stripping tower of Jam Petrochemical LLDPE Unit, a large number of hydrocarbons is released from the top of the tower. In this study, by providing a suitable solution, toxic and dangerous gases can be prevented from entering the atmosphere, and also the energy of fossil fuels and their compounds can be used from an economic point of view. Therefore, the combined cycle has been used to produce power and water vapor useful for the unit itself. To enable power and steam production, the output results of the unit, as well as the combined cycle, have been simulated using ASPEN-PLUS software. The results showed that the use of the combined cycle produces 29.9 MW of power and also 3500 kg / h of steam. From this amount of power generated, all the required electricity related to the compressor of the linear light polyethylene unit can be supplied, and also the generated steam can cover the steam related to the steamer area and prevent the entry of toxic and dangerous gases into the environment.
