Although no two Chlorosulfonic Acid (un)loading solutions will be identical, the product itself determines much of the critical design criteria that will ensure that optimum safety and productivity can work together in harmony. 

What is Chlorosulfonic Acid? Chlorosulfonic Acid is a colorless to slightly cloudy fuming liquid with a strong odor that’s used in the production of detergents, dyes, pesticides, pharmaceuticals and resins.

In the United States, Chlorosulfonic Acid is a “tight-fill” (closed-loop) (un)loading operation and is loaded into rail cars via chemical hoses, 316 stainless steel or 3” PTFE lined loading arms. Chlorosulfonic Acid  if not handled properly can cause serious injuries and Personal Protective Equipment (PPE) is required. Additionally, because operators are on top of the vehicles during the loading process, robust, well-designed fall prevention is essential to ensure increased throughput, without compromising operator safety.

Chlorosulfonic acid is typically shipped in 10,000 gallon DOT-103 rubber lined, 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.
