What should be noted before starting up an air separation unit
Thread Content
Thank you all; I will keep in mind what everyone has discussed
This topic is too broad: Before starting the machine, make sure that the distillation tower is in a closed state. When the valve handwheel automatically releases air, be careful not to allow overpressure in either the lower or upper sections of the tower. Also pay attention to preventing the unit from vibrating, and keep an eye on temperature and stress levels to avoid damaging the pipelines. I don’t understand whether your ‘air separation’ refers to the whole process or just the distillation part. We are divided into two parts: unit groups and air separation.
Whoa, that’s a big problem! ! You can refer to the pre-startup inspection items for each individual machine and verify them one by one.
It is divided into two parts: the unit without separation and the air separation unit. 32,000 low-pressure air separation,
