摘要： 在现有原油常减压装置基础上进行了扩容改造,为了验证扩容后的常减压装置能否满足工艺要求,
需要对流程进行调整。基于蒸馏原理,对常减压蒸馏塔建立包含质量平衡、相平衡、摩尔分数归一化和能量平衡等
方程构成的MESH 模型,在Pro/II平台上进行流程模拟,获得各塔侧线产品的温度和压力等关键参数,并与现场工
艺要求进行对比。流程模拟结果与现场工艺要求吻合良好,说明模型可靠,流程满足工艺要求。各蒸馏塔温度和气

Abstract: New flow was need to be rearranged in order to satisfy the requirement of technology due to the reconstruction of atmosphere-vacuum distillation equipment for enlarging working ability in the present condition. Based on the fundamental of distillation, MESH model including equations of mass balance, phase equilibrium, mole fraction summations and heat balance for atmosphere-vacuum distillation column was established. The key parameter such as temperature and pressure of product was obtained through solution of the model on Pro/II platform. The comparison of simulation results with requirement of spot technology was analyzed. Good agreement between the results of simulation and requirement of spot technology approves that the model is valid and the rearrangement of flow satisfies the requirement of technology. The profiles of temperature and rate of vapor and liquid versus tray number reflect the influence of feeds, products, and cooling cycle in the middle of columns on process of distillation very well.
