不同掺炼比的常减压装置模拟研究

采用Petro-Sim软件对常减压装置进行模拟,分析现有设备能否满足不同的俄罗斯原油掺炼比,并为不同工况下装置的操作条件调整提供指导。为防止减压塔塔顶负荷过高,实际生产时减压炉炉管未投用注汽,增加了油品在炉管内的停留时间,可能会导致油品的大量裂解和结焦。通过减压炉模拟结果建立油品结焦曲线,从而可直观判断油品结焦倾向,判定安全操作区域,指导装置生产。

Simulation Study of Atmospheric-vacuum Distillation Unit with Different Crude Oil Blending Ratios

Petro-Sim software was adopted to simulate atmospheric-vacuum distillation unit so as to analyze whether the existing equipment can meet different blending ratios and to provide the guidance for adjusting the device's operating conditions under different working conditions.To prevent high load at the vacuum tower o-verhead,the vacuum furnace tube didn't implement steam injection in the actual production,and increasing the residence time of the oil in the furnace tube may lead to a large number of oil cracking and coking.Having the results of simulating vacuum furnace based to create coking curves can visually determine oil coking tend-ency and determine safe operating area as well as guide the production.
