面向过程控制的两段提升管重油催化裂解动态建模
Process control oriented dynamic modeling for two-stage-riser catalytic pyrolysis of heavy oil
摘要
Abstract
The two-stage-riser catalytic pyrolysis technology of heavy oil for maximizing propylene, features the possibility of feedstock diversification, high-yield of propylene and high-value gasoline, which enables a bright future for the related industrial applications. Modeling, nonlinear analysis, and control are important aspects for achieving high mass/energy conversion and therefore improving the competitiveness of the TMP technology. This work concentrates on the dynamic modeling for process control purpose. First, mass and energy balance models for the first riser, the second riser, the stripper, the combustor, and the dense region of the regenerator are established and connected by the spent and regenerated catalyst flow among them, forming an integrated dynamic model of the TMP process. It showed that numerical simulation of the main process variables to perturbations in potential manipulated variables not only validates the effectiveness of the set model but also presents strong interactions among two risers and the regenerator system. In total, the built model is well-suited to be adopted as a reference model for subsequent nonlinear analysis and model-based advanced control investigation.关键词
