Modeling and Simulation for Olefin Production in Amir Kabir Petrochemical

Abstract — The Ethylene production process is one of the most important aspects of a petrochemical plant. The bulk of the worldwide annual commercial production of Ethylene is based on thermal cracking of petroleum hydrocarbons with steam. This process is commonly called Steam cracking process. This article deals with Amir Kabir Petrochemical Olefin Furnaces that are located in special region of Bandar Imam in Iran and all required information and data for modeling are offered in this article. In this research, the effect of COT (Coil outlet temperature) on the reactor yield is gained. A simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking furnace. The model is used to predict the steady state profile of Ethylene and Propylene products yield. To study even more, the thermal cracking is simulated with Linde company software. The results of mathematical model and simulation have been compared with laboratory results of Olefin unit of Amir Kabir Petrochemical.
