The installation site must have good ventilation conditions or ventilation and ventilation devices, and can safely discharge liquid and gas. The installation site must be provided with safety exits and safety signs around. There must be sufficient water sources near the installation site, the site must be equipped with fire-fighting equipment, there must be no inflammable and explosive materials around, and the site must be kept clean. It is easy to set up walls or fences in the storage, vaporization, filling, and use of liquid oxygen. Open fire is strictly prohibited around the storage, vaporization, filling, and use of liquid oxygen, and all sources of ignition are eliminated, and there are obvious fire prohibition signs.

2. Safe use of liquid oxygen storage tanks

• The filling rate of the container shall not be greater than 0.95, and overfilling is strictly prohibited.
• Before the container is put into use, it should be checked whether various valves, instruments an,d safety devices are complete, effective, sensitive and reliable in accordance with the provisions of the "Stationary Pressure Vessel Safety Technology Supervision Regulations" to ensure safe use.
• The pressure gauge used must be an oil-free pressure gauge. The material of safetthe y valve and explosion-proof device should be stainless steel, copper or aluminum, and must be degreasing and degreasing.
• Before using the container, vaporizer a,nd piping system, oil-free dry air or nitrogen should be used to remove moisture or moisture.
• The gas outlet temperature of the cryogenic liquid vaporizer should not be lower than -20 degrees.
• When the container is filled for the first time, it should be filled slowly at first (the valve should be opened slowly), and then gradually accelerated to reduce the thermal shock damage to the container and the evaporation of liquid.
• When the valves, instruments, pipeline connection joints, etc. on the equipment are frozen, it is strictly forbidden to use a hammer to beat or heat with an open flame.
• The liquid oxygen in the liquid oxygen container should be regularly analyzed for acetylene content, at least once a month, and the acetylene content should not exceed 0.1×10ˉ6, otherwise liquid oxygen should be discharged. The determination method of acetylene content is determined according to "colorimetric method" chemical analysis or chromatography.

Cryogenic tanks are an essential part for many industries, as they are a key element to store certain gases crucial for diverse processes. In light of such importance, we take a look at the different possibilities in the current cryogenic tanks market and provide 4 key questions to answer before acquiring a cryogenic container.

Use and utility of cryogenic tanks

Cryogenic tanks are a type of industrial storage tank ideal for situations where large quantities of gas need to be stored in liquid form.

They are the right solution to store substances such as Liquid Oxygen, Liquid Nitrogen, Argon, C02, LNG, LPG, Liquid Hydrogen, etc, all of which must be stored at very low temperatures in order to maintain their properties. Thus, it&#;s common to hear of a cryogenic oxygen tank, a LNG cryogenic tank, and so forth.

As more and more industries require the gases mentioned above, demand for cryogenic tanks keeps growing and is projected to grow at a higher rate than 5% CAGR between and . 

The main characteristics of an adequate cryogenic storage tank include:

• They&#;re versatile, provide an optimal internal distribution and thus optimize resources. They allow for the installation of a centralised network for the optimal distribution of the different cryogenic gases used, so that there is no gas return to the plant
• Improved loading process through the use of vaporisers, so that the liquid gas passes directly from the production plant to the user, avoiding sudden movements and improving stability and safety.
• Higher purity than other storage systems, as the gas remains isolated in a hermetically sealed tank so that the possibility of contamination with any external agents is minimized.
• Because they&#;re hermetically sealed, they remain stable and thus are safer than other storage alternatives. Also, as the cylinder transfer within the facilities is avoided, unnecessary risks aren&#;t taken.

Types of cryogenic tanks

The structure for cryogenic tanks is made of three parts:

• An inner vessel made of stainless steel and designed to withstand very low temperatures.
• An outer vessel made of carbon steel. In order to guarantee cryogenic temperatures and safety, these two vessels are insulated from each other by a combination of materials that provide such insulation.
• In addition to these two containers, a cryogenic storage tank is also equipped with a pressure regulation system, which is specifically designed to ensure that the cryogenic tank always operates at a constant pressure. At the same time, this pressure is set with the user&#;s needs in mind.

While cryogenic tanks have this basic structure in common, it&#;s possible to distinguish between two types of cryogenic container: 

• Flat-bottom cryogenic tanks, such as the flat-bottomed tanks Cryospain has recently installed in the USA.
• Large vacuum-insulated cryogenic pressure vessels, such as the new vacuum insulated vessels Cryospain has generated in collaboration with IDESA, which allow for large-scale cryogenic storage.

How to choose a cryogenic container?

Depending on the substance to be stored

When choosing cryogenic tanks, companies must consider what substances they need to store, and communicate it to the tanks manufacturer. 

Different substances will require a different tank shape and design, so that it perfectly adapts to the cryogenic liquid it will need to store. 

Some common substances that require a cryogenic container include: 

• LIN (liquid nitrogen) 
• LOX (Liquid Oxygen) 
• LAR (Liquid Argon) 
• CO2 (Carbon Dioxide) 
• LNG (Liquefied Natural Gas)
• LHe (Liquid Helium)
• LH2 (Liquid Hydrogen)
• LPG ( Liquefied Petroleum Gas) 
• Liquid Ethylene

Depending on the size

Different companies will be in need of different tank sizes, depending on their substance demand and use, among other factors. At Cryospain we are specialized in tanks for large quantities >500 m3

Depending on the material

Stainless steel and carbon steel are the main two materials for building cryogenic tanks. At the same time, different insulating materials can be used: from cellular glass, to rockwool and expanded perlite. Thus, each project must be studied separately, in order to ensure the right materials are used. 

Other considerations

Other criteria to pick the right cryogenic tanks can include: 

• The need to comply with national and/or international regulations.
• The geographical location where the tanks will be installed. For instance, seismic criteria must be considered. The difficulty to access the are might also present a challenge, like it did when Cryospain built a flat-bottom cryogenic tank in Santa Cruz, Bolivia.
