Abstract
This paper describes the mathematical modeling of the physical-chemical phenomena in the coking furnace and coke drum in a steady-state delayed coking unit based in a lumped kinetic scheme and vapor-liquid equilibrium conditions. Feedstock and products composition, and molecular structure are also required.
For better understanding of the coking process and effect of the feedstock physical-chemical properties on yield and quality parameter of the products, especially the petroleum coke, molecular characterization of crude oil and heavy fraction was carried out by MALDI TOF mass spectrometry. Mathematical algorithm has been developed based on experimental data and operating conditions from an industrial delayed coking unit. A good prediction capability of the model and an accurate industrial unit representation of the industrial unit is expected. The developed model will be used for monitoring the industrial process and implementing real time optimization (RTO). Meanwhile, the acquired knowledge obtained during the model development has already improved the quality of green coke produced and the operational procedure of industrial plant.
