Caustic Soda Storage Tank Design

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.

Caustic soda storage tank design.

A second tank discharge and a manway at the bottom of the tank for cleaning is recommended. Service selected will depend upon such factors as size and location of storage rate of consumption plant location freight rates etc. Liquid caustic soda is corrosive. 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.

The water should be lukewarm 80 100 f 27 38 c. Looking for a caustic tank solution. Most caustic soda tanks offered by plastic storage tank distributors are made from polyethylene. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air.

Home chemical storage sodium hydroxide defying a chemical that finds leaks. Storage temperatures for caustic tanks should be beneath 100 f for polyethylene tanks and beneath 120 f for carbon steel tanks. Never add water to the caustic soda solution. Always add caustic soda solution to water with constant agitation.

Choose design tanks for your next tank project. If these elevated temperatures are required tank annealing and or naoh resistant corrosion barrier coatings should be considered to counteract potential tank damage. That is not the best choice if you are storing caustic tanks are storing concentrations of 50 or higher. Due to the dynamic nature of chemical storage and chemical processes it is important.

Terminals are used to maintain. Never start with hot or cold water. The nature of the service environment including the temperature and concentration will largely determine which materials are most appropriate. The addition of caustic soda to liquid will cause a rise in temperature.

If you look at an impartial chemical compatibility guide you will find that polyprolypene is a much better choice for caustic tanks. Currently caustic soda is stored in fiberglass stainless steel carbon steel low carbon steel lined steel and plastic materials. 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. 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.
