Do You Know Your Storage Tank’s Chemical Compatibility?

If you’re storing hazardous fluids such as corrosive acids, bases or aggressively oxidizing chemicals, you need to be confident that your chemical storage tank can meet your expectations for years. You can’t afford to invest in a system, only to discover a year later that your tank isn’t compatible with the chemicals you’re using. That’s a loss of product, time, and money—and it could put your people, equipment and environment at risk, as well.

Performance Under Pressure: Is Your Chemical Tank Wall Thick Enough?

If you want your polyethylene chemical storage tank to last for its full lifetime, you’ll need to make sure your tank has the right specific gravity rating. Every chemical has its own specific gravity, and it’s critically important that your tank is designed to meet the demands of the particular chemical you’re storing. Tanks that are rated too low can suffer from mechanical stress and early failure.

Polyethylene Tank Heating Systems and Insulation - Frequently Asked Questions

Maintaining the proper temperature of a chemical is often critical to safe storage. For example, sodium hydroxide at a 50% concentration will start to crystallize at or below temperatures of 60 degrees F. With polyethylene tanks, heating pads and insulation can maintain the specific temperature of the chemical you’re storing—even when your chemical tank is exposed to low air temperatures.

Explained: Sulfuric Acid Storage Requirements

Sulfuric acid is one of the most widely used chemicals in the United States. More sulfuric acid is produced every year than any other chemical. It has a multitude of industry-specific uses, such as the production of other chemicals, dyes and pigments, water treatment and fertilizers.

This heavy, corrosive chemical requires a specifically designed storage system. That’s why Poly Processing follows engineered guidelines that ensure safety and enhanced tank life.

How to Keep Your Chemicals Cool When the Heat Is On

With some chemicals, it’s critical to keep them cool because they will lose their concentration when they heat up. Sodium Hypochlorite is a prime example of that. As it heats up, it starts to lose its strength, and it begins to release gas and free radicals. Its strength can diminish dramatically with heat and UV.

So it’s important to keep the chemical as cool as possible from the moment it arrives at your facility. Other chemicals are similar—if they become too warm, they won’t perform as well as you need them to.
