The calculated results from the mathematical simulation of an industrial ethane pyrolysis process carried out at the Ethylene-Polyethylene Works in Sumgait under the average constant thermal stress of radiant coil were compared with the results calculated for the same process but using the suggested method of zoned fuel gas supply. The derived mathematical description of the industrial feedback process is given. The optimum thermal stress values calculated from the mathematical model for each zone were used to calculate the optimum fuel gas supplies to each zone, providing the maximum yields of the target products. The results of the comparison of the suggested method of conducting the process with that accepted in industry are evidence of the advantages of the fuel gas supply by the coil zones. This essentially saves fuel gas and provides a higher yield of the target products and results in a higher profit for the company. An expression is given to calculate the optimum fuel gas supply to each zone, even under variable reactor inlet conditions (loading and inlet temperature), which allows for the effective control of the process.
