Tank barges

Chlorine is stored and transported as a Hquefied gas in cylinders of 45.4-kg or 68-kg capacity that are under pressure and equipped with fusible-plug rehef devices. Quantities in the range of 15 to 90 t are transported in tank cars having special angle valves on the manhole cover on top of the vessel. Tank barges of the open-hopper type having several cylindrical uninsulated pressure vessels are used for amounts ranging from 600 to 1200 t. Road tankers are used for capacities of 15 to 20 t. 

ASTM D 4057-95 contains procedures for sampling bulk oil in tanks, barges, etc.

Removal of phosphohpids is desirable because crude oil stored for extended periods is apt to deposit sludge in the bottoms of storage tanks, barges, or rail tank cars (21). Phospholipids (1-3%) represent the bulk of the fat-soluble materials in most crude vegetable oils and are particularly troublesome with soy oil. Soybean oil is the major commercial source of lecithin. 

U.S. Inland Waterways. The present system of more than 25,000 miles of inland waterways (excluding the Great Lakes) is being plied by approximately 4,000 tugs and tow boats, 2,600 tank barges, and 14,000 dry cargo barges. The consistent depth of 40% of these waterways is under nine feet, 25% are nine to twelve feet, and 35% are over twelve feet. 

Many chemical plants are located on our great inland waterways to take advantage of low river transportation costs. Specially designed tank barges ply these rivers with bulk chemicals such as acids, ammonia, chlorine, caustic soda, carbon tetrachloride, acrylonitrile, cyclohexane, urea, turpentine, salt cake, methanol, phenol, styrene, benzene, propane, alcohol, glycol, and many others. 

New barges have already been placed in service for molten sulfur. Barges will ply the waters from Pittsburgh to the Gulf. Improved tank barges will be built for practically every chemical moving in volume lots. 

Propylene, CjH (propene), has a boiling point of -53°F. The flammable range of propylene is 2 to 11%. The vapor density is 1.46, which is heavier than air. The four-digit UN identification number is 1077. The NFPA 704 designation is health 1, flammability 4, and reactivity 1. It is not toxic, but can be an asphyxiant gas by displacing the oxygen in the air. It is usually shipped as a pressurized liquid in cylinders, tank cars, and tank barges. The structure for propylene is shown in the Alkene section of this chapter. 

Ethylene is stored in a cool, well-ventilated area isolated from oxygen, chlorine, and flammable and oxidizing substances. It is protected against lightning, statical electricity, heat, and physical damage. It is shipped in steel pressure cylinders and tank barges. 

JMI owns and operates a construction and repair facility for inland waterway vessels on the banks of the Tennessee River near Calvert City, Kentucky. On May 11, 2007, Specs was hired to work at JMI s JamesBuilt facility, which focuses largely on constructing deck and tank barges, towboats, and dry-docks for the river-shipping industry. JamesBuilt, LLC is a subsidiary of JMI, and the two share the same Human Resources Department. (For convenience, JMI and JamesBuilt are hereinafter collectively referred to as JMI.)... 

Tank Barge Leaks 1,200 Barrels of MTBE [Golob s Oil Pollution Bulletin, 1995)... 

On April 6, 1995, about 1,200 barrels of methyl tert butyl ether (MTBE) leaked from a hole in a cargo tank of the 280-ft tank barge STCO 510 into the Gulf Intracoastal Waterway (ICW) near Cypremort, Louisiana. The crew of the tugboat Aurora, which was pushing the...

Among other gases shipped in SMbstantial quantities by tank barge are inhibited 1,3-butadiene, anhydrous dimethyiamine, anhydrous ammonia liquefied hydrogen, methyl chloride, and vinyl chloride. 

Chlorine is stored and shipped as a liquefied gas under pressure in steel cylinders, ton containers, cargo tanks, tank cars, and tank barges. All containers are equipped with one or more pressure relief devices, except as noted below. Chlorine containers must comply with the authorized DOT or TC requirements. Containers in transportation must be suitably labeled and placarded as required by regulations. 

Methyl chloride is authorized for shipment in cylinders, insulated single-unit tank cars, and TMU tanks and tank cars. It is also shipped in tank barges. Methyl chloride is also authorized for shipment in portable tanks and cargo tanks. 

Under the appropriate regulations, anhydrous ammonia is transported as a liquefied compressed gas in cylinders, insulated and uninsulated tank cars (and multi-unit tank car tanks), barges, and tankers. It is stored in bulk in large-capacity containers installed...
