Air separation project, water-cooled tower, anti-freezing
Thread Content
When the air separation plant in the north is shut down for an extended period during winter, are anti-freezing measures necessary at the air outlet at the top of the water cooling tower?
Yes. A anti-freezing and anti-condensation plan should be developed based on your company’s actual regulations, environmental conditions, equipment characteristics, and maintenance inspection results, in order to implement the necessary anti-freezing and anti-condensation measures.
Just drain the water when parking.
There are concerns that some low points may not be cleaned thoroughly; one option is to use the residual pressure air from the air-cooled tower to blow into the water-cooled tower while the system is stopped, which can ensure that the pipelines are properly cleaned of water.
