Liquefied compressed gases cargo tanks

Nitrous oxide is contained and transported in its liquid phase in high-pressure gas cylinders or in liquid cylinders. It is transported as a liquefied compressed gas under high pressure in cylinders and at lower pressures and reduced temperatures in refrigerated cargo tanks and insulated portable tanks. Nitrous oxide is stored in a foam-insulated tank accompanied by a refrigeration unit, which is similar to the tank used for carbon dioxide. 

In commerce, hydrogen sulfide is transported as a flammable liquefied compressed gas. It is transported and stored under its own vapor pressure in authorized cylinders, tank cars, and cargo tanks (tank trucks). It is used in research, in metals refining, and in the production of a number of basic and specialty chemicals. 

Anhydrous hydrogen chloride is shipped as a compressed liquefied gas under its own vapor pressure in cylinders and in tube trailers. It is also shipped as a refrigerated liquid in insulated tank cars and cargo tanks.
