Hydrochloric Acid Storage Requirements

Hydrochloric acid (HCl), also known as muriatic acid, is toxic and highly corrosive. The chemical is used in many different applications, including chloride production, refining ore and producing metals like tantalum and tin. 


Because HCl is such a powerful acid, it is often used for neutralizing basic solutions. It also requires careful handling and an engineered storage system that is designed specifically for hydrochloric acid.

 The Right Storage System for Hydrochloric Acid

Poly Processing offers a complete chemical storage system for every industry that uses hydrochloric acid. Because correct storage methods are critical, we offer several storage tank configurations to best meet your specific needs. 

It's important to ensure that your chemical storage solution meets the correct set of standards for your specific application. Poly Processing is committed to the highest standards and we are the only company with a complete chemical tank system certified to NSF/ANSI 61 standards. NSF/ANSI 61 relates to water treatment as well as the stringent requirements that control equipment used in water products and potable water.

Because HCl is highly corrosive, we recommend specific tank safeguards. In the event of a chemical spill, secondary containment is critical for preventing damage to equipment and protecting your employees. Our
SAFE-Tank® system is a double-wall tank that completely contains a spill if the primary tank becomes compromised. This tank-within-a-tank design is ideal for containing hydrochloric acid in the event of a chemical spill.

Tank Fittings for HCl

The tank isn’t your only concern in storing hydrochloric acid. Metal tank fittings are susceptible to corrosion as well, and leaks can form at joint fittings. Our slope-bottom IMFO® tank features an integrated outlet that provides full drainage without exposure to metal fittings. The unique sloped bottom minimizes the hazards associated with maintaining a traditional vertical tank—especially one that stores HCl.

Scrubbing Hydrochloric Acid Fumes


Your chemical storage system isn’t complete without a chemical fume scrubber to prevent fumes from venting into the atmosphere. Hydrochloric acid produces toxic fumes that can corrode equipment and cause long-term bodily harm. Improper scrubbing creates a false sense of security and puts your people in jeopardy. 

Poly Processing offers manual and automated scrubbers for hydrochloric acid tanks. Automated scrubbers continually monitor the pH of the scrubbing media and automatically change out the media when the pH becomes too low or too high.

It’s very important to properly size your fume scrubbers, based on the size of the tank. We’ve seen companies design their own scrubbing system, and it often backfires. We can help you determine your scrubber requirements. Contact Poly Processing to design your tank system and fume scrubbers.
