Many industrial chemical applications use mixers to create products, keep chemicals in suspension, treat wastewater, or dilute the chemical. Polyethylene tanks are well equipped to handle that type of process, as most chemicals can be safely combined.

On January 9,2014, a chemical spill fouled the water supply for thousands of West Virginians. "Crude MCHM," 4-methylcyclohexane methanol used in washing coal and removing impurities, leaked from a facility into the Elk River near Charleston, WV. In addition to the leak at the chemical storage facility, the organization has since been cited for unsafe storage conditions at a second chemical storage site. The company had subsequently filed for bankruptcy.

Most chemicals emit vapors during storage, but certain substances present unique challenges that demand specialized solutions. Chemicals such as hydrochloric acid, acetic acid, and hydrofluoric acid generate particularly corrosive vapors that cannot be safely released into the environment. These aggressive fumes pose serious risks to storage infrastructure, surrounding equipment, and personnel safety.

The chemical storage tank industry presents unique workplace challenges, as workers frequently access elevated equipment and fittings on the domes of storage tanks. According to the World Health Organization, falls rank as the second leading cause of unintentional injury death worldwide. For chemical storage facilities, implementing robust fall prevention measures is absolutely critical.

When operating chemical storage facilities, there might come a time when you need to repurpose a tank to store a different chemical. This transition requires careful planning and should not be done without performing due diligence. Any time you repurpose a chemical tank for a different stored chemical, it requires critical considerations for safety, chemical compatibility, and regulatory compliance. In almost all cases, we recommend purchasing a new tank for the chemical you want to store, because every tank is engineered specifically for the particular chemical you originally intend to store. Under certain scenarios, it may be possible to repurpose a chemical storage tank. Here's an introductory overview of a few critical considerations that would need to be addressed when evaluating tank repurposing.

Secondary containment is an important safeguard that helps plant operators mitigate the costly risks of chemical spills. Many companies are realizing the business advantages of switching from open-top tanks and concrete basins to a fully enclosed double-wall containment system. When our customers are weighing their options, they usually have several questions about double-wall containment. Here are some of the most common questions and answers about double-wall containment systems.

Properly treating wastewater is an important, but often misunderstood process. If wastewater isn’t treated correctly, it can be extremely harmful to our environment, including the people and animals that live in it. There are several different elements involved in treating wastewater, including physical treatment that removes particles and debris. However, the chemical treatment of wastewater is especially important.

Sulfuric acid (H2SO4) is an NSF/ANSI 60 approved chemical at a 98% concentration or less. Poly Processing’s tank systems are NSF/ANSI/CAN 61 approved to store Sulfuric acid at 98% concentration or less. Sulfuric acid is a highly corrosive mineral acid that challenges traditional storage options. This pungent, colorless to slightly yellow viscous liquid is occasionally dyed dark brown during production to alert people to its hazards. The biggest challenges in working with sulfuric acid are that it is an aggressive oxidizer and it is very heavy. These challenges threaten the strength and design of many storage tanks. Poly Processing’s tanks and fittings can be combined specifically to store sulfuric acid and reduce the risks. Let’s take a closer look at what sulfuric acid is, how it’s used, and how you can overcome its corrosive challenge with the right storage tanks.
