Although no two DDBSA 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 Dodecylbenzene Sulfonic Acid? Dodecylbenzene Sulfonic Acid is a thick, light yellow to brown liquid that is soluble in water.  As an extremely versatile cleaning agent, DDBSA is commonly used to make detergents and other cleansing products such as shampoos and hair conditioners.  It is corrosive to metals and human tissue.

DDBSA is typically shipped in 26,000 gallon DOT-111 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.

Tank truck (un)loading procedures are similar to railcar applications with the trailers meeting established DOT requirements for transporting DDBSA or other commodities.  Approved DOT trailers include MC 307 or low-pressure chemical ISO containers. Trailers and ISO’s are typically bottom unloaded. An extension pipe with two valves is flanged to the top of the trailer.
