What You Need to Know About Tank Blanketing Systems

For many industries and facilities, oxygen is bad news for some chemicals stored in tank systems. Often, when the storage material comes in contact with oxygen, the substance oxidizes and degrades, or it can dry out. In any scenario, coming into contact with oxygen means you’ve lost product — which translates to less revenue and costs of replacement.

Tank blanketing helps prevent contact with oxygen, and Poly Processing is your partner for protecting your stored materials.

Keep Moisture Out of Your Chemical Storage Tanks

Bulk stored chemicals can become contaminated from two major sources: debris and moisture. As the product is emptied from the chemical storage tank, dirty air and moisture can be drawn into the tank. Temperature fluctuations can also cause the tank to expand and contract, so that it “breathes” contaminants in and out.

Maintaining chemical purity is essential in many industrial chemical applications, such as computer chip manufacturing, food processing, clean in place, and pharmaceutical manufacturing. Contaminated chemicals can become less effective, and more hazardous to your storage equipment. 

To prevent contamination, Poly Processing often recommends installing special accessories. Tank vent dryers and desiccant filters may be your best choice for keeping moisture out of the chemical storage tank.

Tank vent dryers can be especially valuable if you’re storing sulfuric acid. Because concentrated sulfuric acid is hygroscopic, any moisture entering the tank will be quickly absorbed into the chemical. If your supply of sulfuric acid isn’t frequently replenished, the top layer of acid will become more diluted, and more corrosive. As the contents continue to sit in the tank, the top layer of weak acid will corrode a ring around the inner tank wall.

What's the Best Tank Heating Controller for Temperature-Sensitive Chemicals?

Maintaining the proper temperature of a chemical is often critical to safe storage. For example, sodium hydroxide at a 50 percent concentration will start to crystallize at or below temperatures of 60 degrees. For polyethylene chemical storage 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.

What You Don’t Know About Flexible Connectors and Isolation Valves Could Hurt You

One of the most important design considerations of any chemical storage tank system is the use of flexible connectors and isolation valves. When paired correctly, these accessories will not only help ensure your storage tank’s longevity, they can also protect the tank from hinge points that cause dangerous leaks.

Which Tank Mixing System Is Right for Your Chemical Tank?

Many industrial chemical applications involve mixing to create a different product, keep chemicals in suspension, for wastewater treatment purposes, or to dilute the chemical. Polyethylene tanks are well-equipped to handle that type of process, as most chemicals being mixed can be safely combined. There are two basic types of mixing systems that our tanks use—mechanical mixers and pumps.

The Simplest, Safest Way to Measure Chemical Tank Levels

Reliably knowing the level of the liquid in your chemical storage tank is critical to maintaining your operations without interruption. Not only is the level an indicator for ordering more chemical, but certain chemicals have to be stored at a specific level to maintain their properties or operational requirements.


A level gauge monitors the liquid level of the chemical you’re storing in your polyethylene tank. There are several types of gauges, including clear tube level gauges and ultrasonic level gauges. While Poly Processing can provide a variety of level indicators, we almost always recommend our reverse float gauge.

Can I Use Handrails with a Polyethylene Tank?

Various types of chemical storage systems have handrails along the top of the tank, but Poly Processing tanks don’t. Polyethylene tanks can’t support handrails, and the tanks shouldn’t be walked on. The domed surface can be very slippery, and the plastic can become brittle over time and possibly crack under a person’s weight. So how do you safely inspect manways, check gauges, and service level sensors or mixers?
