Cryogenic gas tanks

The Liquid Dispensing Tank. As opposed to high-pressure tanks filled with a highly compressed gas, cryogenic gas tanks hold the liquid form of a gas and are insulated to maintain the cryogenic temperatures necessary to maintain the gas in its liquid state.

Monitoring the purge gas from cold boxes and double walled insulated cryogenic storage tanks. 

An external regulator must be attached to a gas dispensing tank (just as you would to a high compression tank) to control the gas (tank) pressure to the desired (outflow) pressure. Liquid cryogenic tanks follow the same CGA (Compressed... 

For larger volumes of LPG storage, some organisations use cryogenic storage tanks which are constructed in a similar manner to tanks for the storage of LNG Giquefied natural gas). ... 

Large institutional and commercial refrigerators, freezers, and cold storage areas, including cryogenic equipment and gas tanks, are insulated with polystyrene or polyurethane foams. Polystyrene foam is popular where cost and moisture resistance are important polyurethane is used for spray application. Polystyrene foam is also used in load-bearing sandwich panels for low-temperature applications. 

Three-dimensional glass fiber, as shown as 5 of Figure 52, can be used for batch and continuous processes (23, 24). This foamed composite is proposed for use in cryogenic insulation, such as liquid natural-gas tank insulation. However, its manufacturing process seems to be very complex and production costs would be high. 

Neon is not explosive or flammable. Hazards related to neon include use of cryogenic neon-gas tanks, emission of eye-damaging light from lasers, or escape of mercury, cadmium, or lead from luminous tubes. The manufacture of neon-type advertising signs are of special concern because such signs are often produced by small business artisans who may have limited knowledge or resources to deal with hazardous material, such as mercury and lead, which have been documented to contaminate these workplaces. 

The N2 used for well stimulation is transported to the well as a liquid in a cryogenic transport tank. The tank that contains the N2 is kept at a temperature of —196 °C and a pressure of 30 kPa. The liquid N2 is pumped with a cryogenic positive displacement pump into a heat exchanger where it is transformed from a liquid into a gas by raising the temperature (Figure 3). The dry gas is pumped into the liquid or slurry treatment line downstream from the liquid pumpers. At this point, the N2 is commingled with the treating fluid and creates a foam that is pumped downhole. 

Cargo tanks are large-capacity cryogenic storage tanks either mounted on a truck body or forming a semitrailer body. The maximum capacity of these units is 11,300 U.S. gal although the most common size used to ship liquefied industrial gas products over the road is 7000 U.S. gal [2]. The truck has a high pressure liquid transfer pump on board which can fill a... 

Cryogenic fuel tanks are essential components for space transportation systems. Materials for cryogenic fuel tanks must safely carry pressure, external structural loads, resist leakage, and operate over an extremely wide temperature range. Aramids exhibit a wide range in service temperature and are therefore candidates for such applications. A wide variety of skin and core materials have been tested for helium gas permeability. It turned out that Nomex is superior in comparison to Kevlar . A low level of permeability could be achieved, which meets the requirements. 

Gas Cylinders and Cryogenic Liquid Tanks Discusses the hazards of gas cylinders and cryogenic liquid tanks, and safety measures to take when handling or working with these containers. 

For the transport over very large distances, e.g. intercontinental shipping, in addition to the superinsulation of the vessel, a so-called nitrogen shield that cools the insulation by means of liquid nitrogen reduces the heat penetration into the cryogenic gas of tank trucks for He and H2 As a rule, trucks for road...
