摘　　要：炼油装置中稳定塔的泄放工况是比较复杂且有代表性的。从12种典型工况着手,分析了各种工况下泄放量的计算。通常,自控阀失效、上游高压气体流入系统的情况为最大泄放量工况。对于再沸器由蒸汽供热而热负荷又比较大的塔系统,全厂停电也是一种较大泄放量工况。The relief condition of stabilization tower in oil refining unit is complex and typical. For the 12 kinds of typical conditions, analyzes the relief volume calculation under each condition. Generally, the condition with auto-control valve failure and upstream high-pressure gas enters into the system has the largest relief volume. To the tower system with the reboiler heated by steam and large heat load, blackout is a larger relief condition.
