低温乙烯储罐安全阀泄放量的计算

Design Calculation for Cryogenic Ethylene Storage Tank Relief Valves

为确保大型低温乙烯储罐在超压工况下的安全,设置两套定压不同的安全阀,分别排至火炬系统和大气系统。介绍低温乙烯储罐各种超压工况,确定排至火炬系统和排至大气系统的安全阀的泄放工况和泄放量。

For big cryogenic ethylene storage tank, there are two kinds of relief valves with different set pressure, which relief to flare and atm. respectively. The potential relief cases are summarized and their relief loads are detailed calculated.
