LNG Storage And Transportation System Rapid Development
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 to bring 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, 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, LNG Storage And Transportation System natural gas transport in the tube; natural gas cooled to -162 ℃, LNG in the form of transport through the LNG ship.
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, LNG Storage And Transportation System so LNG industry has been vigorously developed.
LNG has the following advantages: (1) LNG is in liquid form, gas-liquid volume ratio of about 620: 1, the smaller the volume, suitable for natural gas transportation, LNG Storage And Transportation System storage, 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, LNG Storage And Transportation System the rapid development of the world has become an irreplaceable part of the energy supply, can ease the dependence on oil and 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, LNG Storage And Transportation System in order to maintain the stability of natural gas supply, not only rely on pipeline imports of natural gas, 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.
In the case of a transport ship, LNG Storage And Transportation System diesel fuel and other fuel oil is its main fuel. However, diesel contains a variety of impurities, after burning some pollutants, but also some of the ship's own equipment will produce corrosion, plug and other damage, so some parts of the ship need to be replaced frequently, which increases the maintenance costs of the ship. LNG Storage And Transportation System For LNG carriers, their LNG content is sufficient, and then carry too much diesel will be superfluous. LNG marine BOG (gas generated by LNG evaporation) is mixed with oil for fuel, which not only solves the problem of burning pollutants, LNG Storage And Transportation System but also solves the problem of BOG treatment. LNG as a carrier fuel has the following advantages: (1) to save LNG ship fuel. (2) sulfide, nitrides and other pollutants generated, emissions will be greatly reduced.
China's LNG ship construction technology still need to improve, although the Jiangsu and Zhejiang area of the shipyard can be made in accordance with the standard small LNG ship, LNG Storage And Transportation System but China's LNG shipbuilding technology is still relatively backward, the core technology is a foreign patent, resulting in high cost, low efficiency The If you want to change this situation, or the need for core technical mastery and innovation.
