Mathematical model for the ethane pyrolysis process in coil tubular furnace is proposed. The reacting system is described by the mechanism that includes the 63 chemical reactions and 19 species. It is also considered the changes of pressure, temperature, flow velocity and heat absorption by endothermic reactions. To solve the resulting system of equations, it is used the spline-integration method with implicit scheme. The simulations were performed for the operating conditions of industrial furnace. The numerical simulations for these conditions had shown the good agreement with experimental data. The computational results correctly are predicted the physical-chemical phenomena, observed in furnace and the developed model can be used for its design.
