费托合成反应器温度稳定性控制研究

Dynamic Simulation of the Fischer Tropsch Synthesis Reactor

为了达到优化费托合成反应器温度优化控制的目的,建立了新的反应器模型。由于费托合成浆态床反应器内部反应较为复杂,温度变化较大难以控制,所以为了对费托合成反应器建立数学模型并且对生产工艺进行动态仿真,提出通过对费托合成反应装置物料流动方式的分析,结合费托合成反应的动力学、物料衡算和能量衡算,简化反应过程的次要因素,最终建立了浆态床反应器的串联全混流数学模型,并且选用序贯模块法进行求解计算。经过对反应器动态仿真的数值结果与实测值结果相近,证明了建立的数学模型能够很好地仿真工艺流程,控制过程的稳定性。

In order to optimize the temperature of Fischer Tropsch synthesis reactor,a new reactor model is built.Fischer Tropsch synthesis is complex and has huge temperature changes,so it is difficult to simulate. In order to build the dynamic simulation for the Fischer Tropsch synthesis reactor,this paper focuses on the establishment of the dynamic mathematical model for the Fischer Tropsch synthesis slurry bed reactor. Through analysis of material flow,reaction kinetics,mass balance,and energy balance,the continuous stirred tank slurry bed reactor model is established. The dynamic sequential modular method is used to solve the model. The results show that the simulation is consistent with actual production,and the model can simulate the process very well.
