摘　　要：探讨了冷箱分离工艺管道的流速分别与管径、压力降的关系,分享了实际项目现场的冷箱工艺管道设计案例,分析了含氢组分气体和易燃易爆液体流速的选择,介绍了气液两相流流速和管径的设计校核方法,为冷箱工艺管道流速和管径优化设计奠定了一定的基础。This paper discusses the relationship of flow rate with pipe diameter and pressure drop in the process pipeline of cold box separately,and then shares the practical project case on the site design of cold box process pipeline.This paper also analyses the choice of flow rates of gases containing hydrogen gas and flammable and explosive liquids,and introduces the design verification method of flow rate and pipe diameter of gas-liquid two-phase flow,so as to lay a foundation for the optimization design of flow rate in cold box process pipeline.
