Process simulation for a tubular coking heater

Based on the mathematical models proposed in literatures for both inside an d outside of the furnace tubes by using both the static and dynamic experim ental data, a simulation software for steady-state processes which can pred ict the combustion in chamber, the radiation of flue gases and its turbulen t flow as well as the coking reaction, equilibrium evaporation and two-phas e flow and heat transfer of residual oils in tubes is developed. Then, the distribution of process parameters along the tubes, such as residual oil re sidence time, thermal conversion fraction and coking rate in tubes, etc can be obtained.
