fireproof material thermal insulation for lng cryogenic storage

Flame-retardant cryogenic insulation paper(compatibility with oxygen) :

The flame-retardant cryogenic insulation paper is made of super-thin glass wool, which is produced in all -electrical kiln with blaze technology, by a peculiar manufactory process. The insulation paper is often composited with aluminum foil as a thermal insulation material for using in the vacuum jackets of storage and transportation vessels for cryogenic liquids(Liquid Hydrogen liquid oxygen, LNG, liquid Helium, liquid Nitrogen and liquid Argon).Its advantage are flame-retardant at open fire and with the best thermal insulation characteristic(lower thermal conductivity, higher contact thermal resistance),low outgassing rate, light weight, high uniformity and wide range of the application temperature:-269°C-800°C

Q:Liquefied petroleum gas, artificial gas, the calorific value of natural gas: The gas from coal or coke and other solid material, through carbonization or vaporization was prepared, its main components are carbon monoxide, methane and hydrogen. Therefore, toxic gas, air to form explosive mixtures, use should be paid attention.Natural gas general refers to buried in the earth's natural gas formation. But usually called natural gas only refers to a flammable gas rich in hydrocarbon storage in deeper strata, and natural gas and oil symbiosis is often called the oil gas. Natural gas from organic substances into the hundreds of millions of years ago. Here, the main component is methane, formed according to different geological conditions in addition, still containing different amounts of ethane, propane, butane, pentane, hexane and other low carbon alkane and carbon dioxide, nitrogen, hydrogen sulfide and other non hydrocarbons; some gas also contains helium. Natural gas is an important energy source, widely used city gas and industrial fuel; in 70s the world energy consumption, natural gas accounted for about 18% ~ 19%. of natural gas is an important chemical raw material.The calorific value of gas per cubic meter is 8000 kcal to 8500 kcal

Q:Natural gas can be extracted from the use of it?: 3 LNG plant can be divided into basic load type, peak type two. Liquefaction process to APCI (American air liquefaction company) process based. (propane precooling mixed refrigerant liquefaction process)4 China's natural gas accounted for only 2.6% of total energy consumption, by 2010, this ratio is expected to reach 7% - 8%5 China's LNG plant: the end of 1990s, the East China Sea early development and utilization of natural gas in Shanghai to build a daily processing of natural gas accident peak of 100 thousand cubic meters. In 2001, the Zhongyuan Petroleum Exploration Bureau to build the first production of liquefied natural gas units, daily processing capacity of 150 thousand cubic meters. 2002 Xinjiang Guanghui group began to build a processing capacity of 1 million 500 thousand cubic meters of LNG plant, storage tank design capacity of 30 thousand cubic meters. .

Q:Where is the source of natural gas in China: According to the state of natural gas reserves, it can be divided into three types: structural natural gas, water soluble natural gas and coal gas. The structure of natural gas can be divided into crude oil produced by the wet natural gas, and does not contain liquid components of dry natural gas.

Q:How to prevent the explosion of natural gas at home: Natural gas is mainly used for power generation, using natural gas as fuel for gas turbine power plant waste emission levels significantly lower than the coal-fired power plants and fuel, and high power generation efficiency, low construction cost, high construction speed; in addition, the gas turbine start stop speed, load capacity, water consumption, covers an area of province.Natural gas can be used as chemical raw materials. A product with natural gas as raw material of synthetic ammonia, methanol, carbon black and other nearly 20 varieties, the main chemical products two times or three times after processing include formaldehyde, acetic acid, more than two of methyl carbonate and other 50 varieties. Using natural gas as raw material the chemical production equipment investment, low energy consumption, less area, less staff, good environmental protection, low operating costs.Natural gas is widely used in civil and commercial gas stoves, water heaters, heating and cooling, but also for paper, metallurgy, quarrying, ceramics, glass and other industries, can also be used for waste incineration and dehydration treatment

Q:Explain the cause of the expansion of the volume of natural gas after decompression: The molecular distance from the temperature pressure and other relevant natural gas pressure after the pressure becomes smaller and the distance between the molecules become larger and larger number of particles did not change the size of the big

Q:Is there a pressure relief valve can not switch off the gas pipeline: In order to make the gas stove to burn the gas completely, the size of the air inlet on the stove head should be adjusted. Gas is the main component of propane and butane, usually if there is enough oxygen, the flame is blue. At the beginning of the use of propane content, with the extension of the use of time, the content of propane decreased, the content of Ding increased

Q:How much is a cubic gas? Thanks for: The main component of natural gas is methane, a cubic meter of natural gas at 1 standard atmospheric pressure, about 0.72kg/ cubic meters.

Q:Just for the gas, would like to ask you, how to distinguish between gas cooker and gas stove? There is a connection with the burner tube is what material the safety?: The second is PVC rubber hose. The two ends with a metal connector, a rubber composite reinforcement and no reinforcement composite wire wire two categories, to buy a PVC rubber hose reinforcing wire, good safety, length can be arbitrarily selected no length limit. Buy steel wire explosion-proof PVC rubber hose.

Q:Why should the city's natural gas?: It is an important safety measure to ensure the safety of people's lives and property, to detect and prevent accidents.

Q:Compare the advantages and disadvantages of the two kinds of fuel, honeycomb briquette and coal gas according to the experience of life, and give out the advantages of using the three kinds of gas: (2) to reduce pollution, protect the environment, reduce labor intensity, reduce housework; (3) economic benefits; (4) is conducive to the development of diversified products. Lighter gas. Compared with the air, coke oven gas is lighter, if there is a leak of gas in the room, the upper part of the gas content of space than the lower part of the content is high, therefore, once the gas leak, should immediately open the doors and windows of the wind blowing.
