What is LNG

Natural gas consists mainly of methane (usually at least 90%), but may also include ethane, propane and heavier hydrocarbons. The 'pipeline' of natural gas may also include traces of nitrogen, oxygen, carbon dioxide, sulphur compounds and water. Oxygen, carbon dioxide, sulphur compounds and water are all removed in a pre-treatment process. 

The liquefaction process compresses, cools, condenses and reduces the pressure and temperature at which the methane (the main component of natural gas) is liquefied. The entire process can be adjusted to produce the purest possible LNG. 

Storage and regasification of LNG cylinders

LNG receiving stations contribute to the LNG value chain by storing LNG and supplying natural gas to end users. This typically includes pipelines, LNG cylinders, compressors, evaporators, pumps and other components. LNG from LNG carriers is transported to storage tanks via discharge pipelines. The stored LNG is transported to the vaporiser process via pumps in the LNG Cylinder. The vapourisation process is used to deliver the natural gas to the end user. 

Recirculation, depressurisation and unloading are all steps in the LNG unloading process. To prevent the pipeline from heating up before the LNG is unloaded, the unloading pipeline must be kept cold. During the recirculation phase, a small amount of LNG from the LNG Cylinder is continuously circulated through the pipeline to keep it cool. During the depressurisation process, the pipeline pressure is reduced to the amount required to transport the LNG from the carrier to the storage tanks. After the unloading phase, the process enters the first stage of recirculation. 

During the unloading and storage of the LNG Cylinder, the vapour from the LNG evaporates continuously due to the heat absorbed in the LNG Cylinder and cryogenic pipelines. This vapour is called evaporated gas (BOG). This can cause physical damage to LNG facilities due to the 600-fold increase in volume. When BOG is over-processed, more energy is used. Therefore, effective BOG management is needed to save energy. For LNG reception facilities, recondensation and direct compression are popular BOG treatment processes. Using a BOG compressor, BOG from the LNG cylinder is compressed to approximately 10 bar and mixed with enough outgoing LNG to produce a liquid mixture, which is then pumped into a condenser. The liquid mix is compressed to provide pressure and evaporated by brine in a high-pressure (HP) pump. If the rate of LNG indicated in the request is not sufficient to condense it all, the BOG will not condense in the condenser. The HP compressor compresses the remaining BOG in the condenser to pipeline pressure and immediately delivers it to the pipeline where it is mixed with the natural gas (Park et al., 2010). As HP compressors use a lot of energy, it is desirable to reduce the operation of the HP compressor. 

LNG Cylinder cooling

No amount of insulation, no matter how effective, can keep LNG cold on its own. LNG is stored as a "boiling refrigerant", which means that it is a very cold liquid at its boiling point under storage pressure. The temperature of a stored LNG Cylinder is comparable to that of boiling water, but 470°F [243°C] lower. The temperature of boiling water (212°F [100°C]) does not change with increasing heat because it is cooled by evaporation (steam generation). Similarly, if constant pressure is maintained, the LNG will keep its temperature near constant. This is known as "automatic cooling". As long as the steam (vaporisation of LNG vapour in the LNG cylinder) is allowed to leave the teapot, the temperature will remain constant (in the tank). 

If the steam is not removed, the pressure and temperature inside the vessel will increase. Even at 100 psig [6.7 barg], the temperature of the LNG will be approximately -200°F [-129°C]. 

Automotive Fuel LNG Cylinders 

The Automotive LNG Cylinder is a vacuum super-insulated cryogenic container that allows liquid natural gas to be stored at low temperatures for long periods of time and in small quantities. 

Putting safety first. Only LNG Cylinders that pass the tests listed in the codes and standards are manufactured.

Extremely long service life Utilising acquired expertise and know-how to manufacture cryogenic LNG cylinders for industrial applications. 

Excellent insulation 90% insulation technology, does not bend even after 5 days of full charge 

A simple repair structure 

Plan for easy replacement of components in the event of a problem. 

Customised production to customer specifications With our superior approach to LNG Cylinder design and manufacture, we can respond quickly to demand, regardless of vehicle type or volume. 

As we have seen, LNG Cylinders work in extremely low temperature ranges or in low temperature processes. It is important and mandatory that to operate in the cryogenic region, materials and processes must be able to withstand the cryogenic effect. This makes the LNG Cylinder also considered as one of the main components and important equipment for LNG storage systems. 

LNG cryogenic storage tanks

The LNG cryogenic storage tank is a vertical or horizontal double-layer vacuum-insulated storage tank for storing liquid oxygen, nitrogen, argon, carbon dioxide and other media, the main function is to fill and store cryogenic liquids. The tank consists of a carbon steel or stainless steel shell and a pressure vessel placed in it. The jacket is insulated with multiple layers of windings to maintain a high vacuum.

 The Cylinder is a high performance vacuum insulated vessel for the storage and transport of cryogenic liquid oxygen, nitrogen, argon, carbon dioxide, liquefied natural gas or nitrous oxide. They can be used for the road transport of cryogenic liquids or for on-site storage and supply. Long storage times and a wide range of applications
