Computer simulation of an industrial ethane-cracking furnace operation

Abstract

A computer simulation strategy is presented that is focused on the application of modeling programs for the simulation of multistage chemical technology processes with a large number of equipment units, including reactors, is suggested for chemical transformation processes in reactors. The submitted strategy allows for the modeling of homogeneous and heterogeneous processes in reactors of any complexity on the basis of experimental data processing. The simulation of reactor processes has been performed with the use of the CHEMCAD program for the ethane thermal cracking. The main products of Steam Cracking Olefin production technology are the ethylene and propylene [1],[2]. In Eastern Europe mainly virgin naphtha, gas oil and hydrocarbon gases C3-C4, liquefied petroleum gasesare used as feedstocks. Depending on the type of the feed different type of furnaces geometry can be built into the unit serve as plug-flow reactors for thermal cracking of larger hydrocarbon molecules. There is a special furnace in the unit that cracks the recycled ethane.
