A Mathematical Model for the Tubular Reactor in a Light Hydrocarbon Pyrolysis Furnace and Its Application |
| |
Abstract: | A kinetic model for cracking and coking reactions of light hydrocarbon feed stocks is developed. The feed stocks consist of nearly 120 individual hydrocarbons up to C_(10)'s. In the model, the hydrocarbons in the reaction system are lumped into 48 components for the sake of simplicity, and 49 stoichiometric reaction equations are established. By combining the material balance computations for each component, the heat balance of reaction tube, and the fluid flow of reaction mixture, a mathematical model of the tubular reactor is set up. It has been used to check and predict the operating conditions of the pyrolysis furnace of Daqing Ethylene Complex. The computed results satisfactorily conform with those of pilot experiments and industrial operation. |
