摘要
本文应用CAESAR II对某润滑油加氢异构化装置预分馏塔抽真空系统进行管道应力分析,结果表明,由于蒸汽喷射器为不锈钢材质且操作温度较高,后冷器入口管嘴法兰压力等级低而受力较大等因素,抽真空系统管道柔性设计具有一定的研究价值。
Using CAESAR II,the pipe stress analysis of the vacuum system of pre-fractionation is taken.The steam ejector is made of stainless steel and has a high operating temperature.The inlet nozzle of the rear cooler has a large force and its flange pressure rating is low.The results show that the flexible design of the pipeline in the vacuum system has some research value.
