LNG Storage And Transportation System Higher Efficiency

LNG (liquefied natural gas) temperature of -162 ℃, is a colorless, LNG Storage And Transportation System tasteless, atmospheric pressure, low temperature natural gas liquefaction form, mainly by methane and a small amount of ethane, propane, butane and other low molecular hydrocarbons and H2S, N2, H2O and other components.

As the world's oil reserves are limited, LNG Storage And Transportation System and the use of oil brought about by greater pollution, people realize that can not be too dependent on oil resources. At the same time, people found that natural gas reserves are relatively abundant, LNG Storage And Transportation System and relative to oil, natural gas is more environmentally friendly, safe and clean. In the natural gas industry, the rapid development of natural gas transport has become a new problem. There are two methods of high economic efficiency, namely: through the laying of pipes, natural gas transport in the tube; natural gas cooled to -162 ℃, get LNG form, LNG Storage And Transportation System through the LNG ship for transport.

Pipeline transport method is only applicable to the adjacent location, the limitations of large, but the resource supply is more stable. And through the form of LNG transport is relatively flexible, consumption is not large, suitable for cross-regional, trans-ocean transport, so LNG industry has been vigorously developed.

LNG has the following advantages: (1) LNG is liquid form, gas-liquid volume ratio of about 620: 1, the smaller the volume, suitable for natural gas transportation, storage,LNG Storage And Transportation System use is also more convenient. (2) LNG contains very little environmental pollution components, the main components CH4 completely burned after the product is CO2 and H2O, very beneficial to environmental protection and sustainable development. (3) LNG calorific value is relatively high, the unit volume of LNG combustion completely produce heat, suitable for fuel.

LNG in recent years, the rapid development of the world has become an irreplaceable part of the energy supply, can ease the dependence on oil energy. In China, natural gas is gradually entering people's lives, including natural gas vehicles, natural gas water heaters, as fuel, etc., the demand for natural gas is also increasing rapidly, in order to maintain the stability of natural gas supply, not only rely on pipeline imports of natural gas, LNG Storage And Transportation System The number of LNG receiving stations is also increasing rapidly, LNG industry chain has gradually become perfect, LNG technology research has become one of the hot spots in global energy research.

LNG storage tank in the construction process has many requirements: the need for normal work in low temperature environment; tank LNG evaporation volume will increase rapidly, LNG Storage And Transportation System resulting in security risks, to ensure safety; inside and outside the tank according to their characteristics, select the appropriate material; Tanks need to have good insulation, reduce wear and tear; LNG Storage And Transportation System storage tanks to be able to withstand special weather and natural environment; tank materials and workmanship must be strict checks.

LNG tank pressure and BOG on the safety of the tank has a great impact, which is the construction of the tank need to pay attention to one of the problems. The temperature is high, LNG Storage And Transportation System the temperature is high, the safety is reduced; the better the insulation, the more safe the tank; can also be To improve the tank nitrogen content of the way to reduce the BOG, increase safety.

LNG storage tank in the construction of a few points is very important: the construction of steel liner, with a large blower to the air compression, expansion of the force, hold the liner, that is, LNG Storage And Transportation System gas blowing lift lining; Ni9 steel performance, but for The welding process between the steel plates of the tank walls is demanding; the technique of laying the bottom of the tank is also extremely important. China's LNG industry is developing rapidly, in order to reduce the cost of LNG storage, LNG Storage And Transportation System but also independent research, master these technologies, and to develop and innovate, which is of great significance to China's energy development.

LNG industry in the country is in the rapid development of the occasion, China's LNG imports are also increasing year by year, while the equipment and the use of high cost, less profit. LNG Storage And Transportation System China can be on all aspects of LNG (transport, reception, storage, processing, use) to use the technology and equipment to increase research and development efforts to master the process of the core technology and heavy and difficult projects, LNG Storage And Transportation System and to be accordingly innovation, the formation of their own characteristics of domestic Equipment and domestic technology, so that you can reduce the cost from the foundation. On the other hand, the rational use of LNG resources is also very critical, should be a unified use of the plan to ensure the economy.
