The loading and unloading of acetic acid requires that safety and productivity are prioritized for the protection of operators and the efficiency of the facility.

What is Acetic Acid? Acetic acid, also known as ethylic, vinegar, or glacial acid is a clear, colorless, organic liquid with a pungent odor similar to household vinegar.  At concentrations of 95 percent, it is commonly used as an intermediate and solvent in the production of chemicals such as vinyl acetate for the production of plastics; cellulose acetate used in the production of films and textiles; and volatile organic esters such as ethyl and butyl acetates used in solvents.

In the United States, acetic acid is a “tight-fill” (closed-loop) loading operation and is loaded or unloaded into rail cars via chemical hoses or 316 stainless steel loading arms. Acetic acid, if not handled properly can cause serious injuries, and personal protective equipment (PPE) for operators is required. Additionally, because operators are on top of the vehicles during the loading process, excellent fall prevention is essential to ensure operator safety without compromising throughput.

Acetic acid is typically shipped in 10,000 gallon DOT-103 insulated or non-insulated tank cars with safety valves.  The rails cars themselves are ~ 9′ outside diameter with an overall length of ~45’ to 50′, with a 6’ x 6’ center opening or off-set crash box openings.
