Reactor modelling and simulation of bubble column for slurry phase hydrocracking of vacuum reside. |
| 초록 |
Slurry-phase hydrocracking recently has gained great interest in heavy oil upgrading because of the remarkable feed flexibility with high conversions, a simple design and an easy operation with nearly isothermal condition. To design a more efficient reactor with optimum reaction conditions, this study proposed one-dimensional dynamic model for a slurry bubble column reactor (SBCR). An axial dispersion model and a gas holdup correlation derived from cold-bed experiment were used to present the hydrodynamics of SBCR. The kinetic models for hydrocracking and hydrotreating were developed from slurry hydrocracking experiment at a CSTR. The proposed model considered the calculation of Henry constants for the volatile components through a state equation and the variation in superficial gas velocity regarding the Gas−Liquid mass transfer. The model was validated with experimental data from a bench scale unit for a wide range of operating conditions. Finally, a parametric sensitivity study was elaborated to analyze the effects of the superficial gas velocity, temperature, and LHSV. |
