A Complete Guide on Sodium Hydroxide Storage Requirements

Sodium Hydroxide in its pure form is a white-colored solid that is usually found in flakes, granules, or pellets.

Usually, it is used as a solid or 50% solution. In its liquid form, it is colorless and denser than water. Being a strong base, Sodium Hydroxide is highly corrosive and reactive in nature.

In its liquid state, it reacts vigorously with metals, such as Aluminum, Magnesium, Copper, and Zinc. It also reacts vigorously with human skin and eyes.

Exposure to Sodium Hydroxide only for a few seconds can cause permanent damage to the optic nerves.

Experts have suggested that this chemical compound often becomes slippery and corrodes the weak portions of the Sodium Hydroxide storage tank, thereby causing multiple leaks.

This means you must take necessary steps to handle the compound safely and store properly.

In this blog, we have highlighted some of the challenges that you may face while storing Sodium Hydroxide, and the measures you should take in order to store it properly.

Challenges when storing Sodium Hydroxide

Due to its corrosive and slippery nature (approximately 79 mPas at 68 degrees F), storing sodium hydroxide in industrial storage tanks is a bit tricky.

So, make sure to measure the pros and cons of your storage options. Always consider the following –

1. Temperature – Temperature is one of the crucial parameters. If a proper temperature is not maintained, the chemical will crystallize and turn solid.

This can lead to unnecessary wastage and damage to the storage tank itself. Experts opine that a minimum of 60-degree Fahrenheit must be maintained.

2. Secondary Containment – Sodium Hydroxide often leads to environmental hazards. That’s why secondary containment is an absolute necessity.

Make sure to surround the primary storage container to collect any spillage of Sodium Hydroxide.

How should Sodium Hydroxide be stored?

Here’s a step-by-step guide on how you can properly store sodium hydroxide.

Studies have revealed that sodium hydroxide should always be stored in a 1.9 specific gravity Sodium Hydroxide storage tank.

The material of the tank components must be pvc/cpvc or 316ss for piping and fittings, EPDM for gaskets, and 316ss for bolts.

The storage temperature must be below 100-degree Fahrenheit for polyethylene tanks and beneath 120-degree Fahrenheit for carbon steel tanks.

The freezing point and viscosity of Sodium Hydroxide vary with concentration. For concentrated Sodium Hydroxide, it is best to maintain an average temperature above 70-degree Fahrenheit.

This will help prevent freezing and caustic deposition. It’ll also promote fluidity.

The storage and piping system should have venting or overflow vents with diameters at least four times the inline pipe.

The tank system should have minimum piping runs to prevent freezing and solid deposition.

Secondary containment measures must be included for every Sodium Hydroxide storage tank. Moreover, the design should be strenuous enough to contain 110% of the total system volume. Double-walled tanks are best-suited for this purpose.

So, here was our in-depth analysis on Sodium Hydroxide storage requirements. We believe it’s always best to use a Sodium Hydroxide storage tank manufactured by a reputable company.
