摘要: GOST标准是前苏联国家遵循的标准。以哈萨克斯坦某炼油厂重油催化裂化装置为例,按照《压力容器、安全阀技术要求》(GOST 12.2.085-2002)的要求,系统地阐述了气体介质安全阀的计算选型,并与API STD 520的计算结果进行了比较。结果表明:不论对于何种气体介质,两种标准计算得到的安全阀所需排放通道面积相差不大,选型结果也基本一致。另外,根据上述GOST标准的要求,对于易燃易爆物质和国家标准GOST 12.1.007规定的1、2类危险物质,以及低温介质,其安全阀应设置机械联锁系统

Abstract: GOST standards are the standards followed by the former Soviet Union. In this paper, a RFCC unit located in Kazakhstan is taken for an example to systematically illustrate the calculation of safety valves with gaseous media in accordance with GOST 12.2.085-2002 Pressure Vessel, Safety Valve Technical Requirements. The results are compared with those of API STD 520. It is shown that, for gaseous media, the required relief orifice areas of the safety valves calculated by the two standards differ not too much, and the selection results are basically the same. In addition, for flammable and explosive medium, hazardous substances of Class 1 and 2 specified by GOST 12.1.007 and low temperature medium, the safety valve should be equipped with mechanical interlock system
