Sulfuric acid (H2SO4) is an NSF/ANSI 61 approved chemical at a 98% concentration or less for Poly Processing’s tank systems. 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 challenge in working with sulfuric acid is that it is an aggressive oxidizer. This challenges 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.

FOG is an acronym for fats, oils and grease, particularly in the context of wastewater collection systems. FOG comes from meat fats and food scraps, cooking oil, shortening, lard, butter and margarine, gravy, and food products such as mayonnaise, salad dressings, sour cream and other foods high in fat.

Poly Processing’s standard crosslinked polyethylene tank systems can withstand process temperatures up to 100°F — but that figure can be misleading, because there are different types of temperature to consider. For example, one of our customers in Texas asked about keeping a polyethylene tank outdoors in extreme temperatures:

No matter what chemicals you’re storing, it’s important to conduct routine storage tank inspections. These inspections are vital to help keep the chemical tanks, fittings, venting and accessories in good working condition—and to avoid costly surprise failures. Even if the polyethylene tank is relatively new, a routine and careful visual inspection is recommended.

Chemical storage tanks expand and contract due to seasonal temperature variations, pressure changes from loading and unloading the contents within the tank, and vibrations from pumps during filling and discharge from the storage tank.

We’ve written several articles about the importance of protecting your chemical storage tank from aggressive chemicals. Mechanical stress can be just as significant, causing polyethylene chemical storage tanks to crack. Mechanical stress occurs when the tank’s structure is compromised after a physical impact with another object, over pressurization, improper venting, or rigid plumbing that doesn’t allow natural expansion and contraction of the tank.

Sodium hydroxide (NaOH), also known as caustic soda or lye, is a common inorganic compound that is typically used as a strong chemical base. Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting.
