Some distillation tower overhead coolers are equipped with non-condensable gas lines while others do not; why is that?

Some distillation column overhead coolers have non-condensable gas lines, while others do not! What are the standards for air-cooled non-condensable gas lines? Please give me some advice!
“Some distillation column overhead coolers have non-condensable gas lines, while others do not! What are the standards for air-cooled non-condensable gas lines? Please give me some advice! ” Answer: Some distillation column tops are cooled with air and contain non-condensable gases, while others do not! The standard for air-cooled non-condensable gas lines is whether there is non-condensable gas present! It is determined by the raw materials and the top pressure of the tower: that’s all.
There are two understandings: first, if the system contains no non-condensable components, then there is no need for the discharge of non-condensable gases; second, the amount of non-condensable gases is low, so they can be carried out of the tower along with the light components~~
