Is it okay to not install a breather valve on a caustic soda storage tank? ?
Thread Content
Excuse me, gentlemen. For liquid caustic soda storage tanks, is it acceptable to omit the breather valve and simply make a vent hole on the top of the tank instead? ? Is this in compliance with the specifications?
Yes, in the caustic soda and PVC plants we build, no breather valves are installed on the liquid caustic soda storage tanks

It depends on the intended use of the alkali solution. If there are requirements regarding oxygen content, it’s best not to make any openings directly
Personally, I believe that when stringent requirements are placed on the specifications of liquid caustic soda, it’s best not to make any openings, as this can affect its purity
The caustic soda solution used by our company for metallurgical and petrochemical caustic washing, as well as for light aromatic hydrocarbon caustic washing, has a concentration of 15%. At the top of the caustic soda tank, there is a vent bend pipe
It’s better not to make any holes directly; otherwise, moisture from the air will enter the tank and affect the quality.
We use 30% caustic soda, and we’ve installed vent holes on the tank top; there are no problems at all. It mainly depends on the specific application and process requirements.
