空分装置高压蒸汽管道在设计中的常见问题分析及改进措施

Analysis of Common Problems in Design of High-Pressure Steam Pipeline of Air Separation Unit and Improvement Measures

空分装置中的高压蒸汽管道具有温度和压力高、流速快、危险系数大的特点,与装置的安全运行密切相关。以35000m^3/h(标态)空分装置为例,分析了高压蒸汽管道在选材、布置、疏水、吹扫等设计方面存在的常见问题,并提出相应的改进措施。

The high-pressure steam pipeline in the air separation unit has the characteristics of high temperature and pressure,fast flow rate and large danger coefficient,which is closely related to the safe operation of the unit.Taking 35000 m^3/h(standard state)air separation unit as an example,the common problems of high-pressure steam pipeline in material selection,layout,drainage,purge,etc.are analyzed,and corresponding improvement measures are proposed.
