Caustic Soda Storage Tank Requirements

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.

Caustic soda storage tank requirements.

The product is shipped in tank trucks railcars barges and ships. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air. 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. Always add caustic soda solution to water with constant agitation.

If these elevated temperatures are required tank annealing and or naoh resistant corrosion barrier coatings should be considered to counteract potential tank damage. So here was our in depth analysis on sodium hydroxide storage requirements. It is extremely important that polyethylene tanks are not over pressurized. Caustic soda is shipped via pipelines tank trucks railcars barges and ships.

Requirements and ensure that all coating and linings. Moreover the design should be strenuous enough to contain 110 of the total system volume. A second tank discharge and a manway at the bottom of the tank for cleaning is recommended. Venting polyethylene storage tanks is one of the most commonly overlooked steps but is a.

Never add water to the caustic soda solution. The caustic soda solution is inventoried in storage tanks prior to shipment. The addition of caustic soda to liquid will cause a rise in temperature. 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.

Never start with hot or cold water. 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. Storage temperatures for caustic tanks should be beneath 100 f for polyethylene tanks and beneath 120 f for carbon steel tanks. Because tanks in caustic soda service will have a specific gravity greater than 1 0 the ul 142 code is not acceptable.

4 of 44 methods of shipping. All oxychem s caustic soda meets the test requirements specified in the food chemicals codex. Terminals are used to maintain. Home chemical storage sodium hydroxide defying a chemical that finds leaks.

Double walled tanks are best suited for this purpose. Sodium hydroxide also known caustic soda is an inorganic compound with formula naoh. Service selected will depend upon such factors as size and location of storage rate of consumption plant location freight rates.
