HCL corrosion protection
Thread Content
There is a large amount of HCL gas in the chlorination workshop; how should corrosion protection be addressed for the electrical equipment and instruments on site? Please, everyone, share your opinions!
It should start with choosing the right material
I believe that installing additional ventilation equipment in the workshop to keep the HCL level in the air below a certain threshold brings direct benefits to both the workers and the equipment. For example: installing ventilation ducts on the roof, or adding axial flow fans, and so on.
Since the instruments need to be checked frequently, the simplest solution is to cover them with plastic film； For electrical appliances used on-site, a corrosion-resistant coating should be applied, one with anti-static properties. I work with vinyl resin, and I know that using vinyl resin is a viable option; it can withstand temperatures of up to 100 degrees Celsius, whether the appliance is dry or wet ； It is also appropriate to have some weakly alkaline solutions on site to absorb HCl gas, such as sodium carbonate, sodium bicarbonate, and so on.
I can only ensure good ventilation; I really haven’t thought of anything specific yet.
It must also be important to keep it dry!
Stop leaks as much as possible to reduce HCL emissions.
