gangway for bulk loading sulfuric acid

SafeFack GX Retractalok SAS gangwayLocated in Magnolia, Arkansas, this chemical facility is a supplier of bromine chemicals, sulfuric acid, and other chemicals. With multiple loading platforms located throughout the facility, this new GX SAS gangway replaced a failing and unsafe gangway from another company. With power assist raising and lowering, this SafeRack GX series gangway is unlike any other, so much so it was awarded product of the year by Occupational Health & Safety magazine. The revolutionary technology assists the operator in lifting the gangway almost effortlessly with instant positive locking, which enhances operator safety while on top of the vehicle. Powder-coating all the surfaces of the safety cage and gangway resist wear and spills while bulk loading the sulfuric acid.

The customer is very satisfied with SafeRacks products and services and will be upgrading nearly all the loading terminals throughout the facility.

Sulfuric acid is typically a close dome (tight fill) loading process into tank trucks via Teflon-lined chemical hoses, braided SST flex hoses, or 3″ stainless steel loading arms with PTFE seals. At deluded concentrations of 93% and above, sulfuric acid can be splash loaded using a carbon steel loading arm.

Depending on the concentration, optional vapor recovery is used in conjunction with a splash plate, vapor cone, or inflatable hatch seal.
Sulfuric Acid Transport

Sulfuric Acid is typically transported in insulated or non-insulated tank cars

Usually in 7,000 gallon DOT 103AW or 13,640 gallon DOT 111A100W2 depending on concentration, that meets the DOT specification for the transportation of sulfuric acid and other like commodities. The rails cars themselves are ~ 9′ outside diameter with an overall length of ~33’ to 41′, with a 7’-4” x 6’  center or off-set crash boxes.  

For safety reasons, pump unloading is the preferred method over dry compressed air unloading for tank cars and trucks. This puts the unloading hose or arm under suction so that any leak can be stopped promptly without the need for venting the tank car or truck of padding pressure.

DOT MC-310, MC-311 & MC-312 tank trailers are used to transport sulfuric acid over roads and highways with a capacity up to 20 to 23 tons (2600 to 3000 gallons)

Tank truck (un)loading procedures are similar to railcar applications with the trailers meeting established DOT requirements for hauling sulfuric acid.  Bottom unloading is also the preferred method for unloading sulfuric acid tank trucks utilizing a 2” or 3” chemical hose or gravity drop bottom unloading arm with a quick release coupler or dry disconnect fitting and break-away.
