Abstract: Based on computer simulation and analysis, the dynamics, physical properties and reactor of the coking furnace in a refinery were discussed, and the mathematical model of the furnace was established. The distributions of temperature, pressure, flow rate, composition of gas and liquid were obtained by analyzing working conditions after verifying model in field. The results showed that the deviation between simulation results and field values was small, and the distribution trend of temperature, pressure and other parameters were consistent with the macroscopic understanding. The established mathematical model can be used to analyze the running parameters of the heating furnace in field and provide theoretical support for design, operation and optimization of the delayed coking heating furnace.

Key words: delayed coking, furnace, simulation, modeling
