基于高温热裂解β-蒎烯生产月桂烯工艺,建立反应核心装置-裂解反应器的动力学模型,并基于g PROMS建模平台,利用不同工况的工业运行数据对模型动力学参数进行估计,进而构建β-蒎烯热裂解反应过程模型。模型验证结果表明,模型对月桂烯产品浓度具有较好的预测性能。同时,模拟分析了进料流量、操作压力和反应温度等参数对月桂烯产品浓度的影响,较佳的工艺条件是蒎烯进料流量为210 L/h,操作压力为0.09 bar,反应温度为510℃,为生产操作条件的优化、负荷的调整以及过程安全平稳生产的运行提供重要参考。
Based on the high temperature pyrolysis of β-pinene for the production of myrcene, a kinetic model of the pyrolysis reactor was established. Based on the g PROMS modeling platform, the kinetic parameters of the model were estimated by using industrial operating data under different working conditions. And then build β-pinene pyrolysis reaction process model. The model validation results show that the model has good predictive performance for myrcene product concentration. Simultaneously, the influence of feed flow rate, operating pressure and reaction temperature on the concentration of myrcene was simulated and analyzed. The optimum conditions were the feed flow of pinene 210 L / h, operating pressure 0.09 bar, reaction temperature 510 ℃, for the optimization of production and operation conditions, the load adjustment and the safe operation of the process to provide an important reference for the operation.
