the ethylene production process is one of the most important aspects of a petrochemical plant the bulk of the wordwide 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 seals with amir kabir petrochemical olfin furnaces that are located in special region of bandar imam in iran and all required information and datd for modeling are offered in this article.in this research , the effect of COT coil outlet temperature on the reator yield is gained . a simulator is developed by the use of a mathematical model , which describes the static operation of a anphtha 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 compony software. the results of mathematical model and simulation have been compared with laboratory results of olfin unit of amirkabir petrochemical.
