Sodium hydroxide also known as caustic soda and lye is a highly caustic compound and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns.
Caustic soda storage tank design.
Choose design tanks for your next tank project.
Service selected will depend upon such factors as size and location of storage rate of consumption plant location freight rates etc.
That is not the best choice if you are storing caustic tanks are storing concentrations of 50 or higher.
Because tanks in caustic soda service will have a specific gravity greater than 1 0 the ul 142 code is not acceptable.
A second tank discharge and a manway at the bottom of the tank for cleaning is recommended.
If these elevated temperatures are required tank annealing and or naoh resistant corrosion barrier coatings should be considered to counteract potential tank damage.
Home chemical storage sodium hydroxide defying a chemical that finds leaks.
For 50 caustic storage a design specific gravity of 1 6 is recommended because caustic soda is difficult to pump when the temperature gets to 60f storage tanks must be heated or kept in a warm room.
Tank inlet should be above the highest anticipated tank level with an inlet dip pipe which extends below the lowest anticipated tank level to prevent splashing of the caustic soda solution.
Terminals are used to maintain.
Most caustic soda tanks offered by plastic storage tank distributors are made from polyethylene.
Substances able to be stored may include caustic soda or sodium hydroxide.
Looking for a caustic tank solution.
Also known as caustic soda or liquid lye sodium hydroxide is used to adjust ph in water and wastewater treatment and in the manufacture of chemicals rayon cellophane pulp and paper aluminum detergents soaps and a wide range of other products.
Always add caustic soda solution to water with constant agitation.
Storage temperatures for caustic tanks should be beneath 100 f for polyethylene tanks and beneath 120 f for carbon steel tanks.
The water should be lukewarm 80 100 f 27 38 c.
Currently caustic soda is stored in fiberglass stainless steel carbon steel low carbon steel lined steel and plastic materials.
Never start with hot or cold water.
If you look at an impartial chemical compatibility guide you will find that polyprolypene is a much better choice for caustic tanks.
The addition of caustic soda to liquid will cause a rise in temperature.
It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air.
Our in house design and engineering teams work with you and our resin suppliers to ensure you have a properly designed caustic tank.
Caustic soda is shipped via pipelines tank trucks railcars barges and ships.
Liquid caustic soda is corrosive.
