waterproof and fireproof 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:What is the composition of natural gas ah? How to do it?
Natural gas refers to natural gas all exist in nature, including all kinds of natural gas of atmosphere, hydrosphere, lithosphere and formation (including oil gas, gas, mud volcano gas and coalbed gas and bio gas generation etc.). The definition of "natural gas", which has been used for a long time, is a narrow definition from the point of view of energy. In petroleum geology, commonly referred to as oil and gas fields. It is composed mainly of hydrocarbons and contains non hydrocarbon gases.
Q:The gas in the gas tank is used up. What's wrong with the water?
1 is the winter weather is cold, gas liquefaction occurs, when the temperature slightly increased, the liquid gas can also burn.
Q:What is the proportion of natural gas?
The main component of alkane gas, including methane, majority, and small amounts of ethane, propane and butane, in addition there are hydrogen sulfide, carbon dioxide and nitrogen and water vapor and a small amount of carbon monoxide and trace rare gases, such as helium and argon. Natural gas before sending to the end user, in order to help leak detection, but also with mercaptan, four thiophene, etc. to add odor to the gas.Natural gas is not soluble in water, the density is 0.7174kg/Nm3, the relative density (water) is 0.45 (liquefied) ignition temperature (c) is 650, explosion limit (V%) is 5-15. Under standard conditions, methane to butane exists in a gaseous state and pentane is a liquid. Methane is the shortest and lightest hydrocarbon molecule.The organic sulfide and hydrogen sulfide (H S) is a common impurity in most cases the use of natural gas must be removed in advance. Natural gas containing sulfur impurities is described in English as "sour (acid)".
Q:Is the gas in the house toxic?
Gas poisoning is carbon monoxide poisoning, is due to the high concentration of carbon monoxide gas inhalation of the human body and lead to poisoning, hypoxia caused by severe damage to the nervous system. Carbon monoxide inhalation of gas, combined with hemoglobin in the blood, the formation of carbon monoxide hemoglobin, so that the blood loss of oxygen carrying capacity, and can increase tissue hypoxia.
Q:How can I get the gas cooker?
The first to open the gas tank, the right hand is the direction of their own twist, and then turn on the gas stove can be it, very simple
Q:How much gas to burn 1 tons of steam
Of course, the quality of the combustion engine is also the most important, good energy saving gas, boiler quality is the main factor of gas steam boiler 1 tons per ton of steam consumption;Per cubic meter of natural gas calorific value of 9000 kcal;Boiler thermal efficiency 0.91;It can be concluded that the boiler heat transfer index is 0.91x9000=8190,By 600000/8190=73.000,In other words, in theory, every ton of water vapor, need to consume about 70-75 square gas
Q:What is the density of natural gas
Under normal temperature and atmospheric pressure, the density of methane is 0.7174kg/m3, the relative density is 0.5548.The density of natural gas is generally 0.75 kg/m3 ~ 0.8kg/m3, the relative density is generally from 0.58 to 0.62.The density of natural gas is related to the temperature, pressure and the composition of natural gas. Under normal circumstances, the density of the natural gas varies from 0.55 to 0.90kg / m3.The relative density of natural gas is the ratio of the density of natural gas to the density of air under the standard state (0, 101.325kPa)
Q:Gas tank valve must not be closed every time
Furthermore, the kitchen switch is not reliable, and some have quality problems
Q:Is natural gas solid?If so, under what conditions will become solid?
Combustible ice combustion equationCH4 8H2O+2O2=CO2+10H2O(reaction conditions for "light") [edit this paragraph] combustible ice found as early as 1778, the British chemist Pudesiteli began to study the gas generated by gas hydrate temperature and pressure. In 1934, people found the ice like solid blockage in oil and gas pipelines and processing equipment, which is not ice, which is now known as combustible ice. In 1965, Soviet scientists predicted that the gas hydrate may exist in the surface layer of the bottom of the ocean, and then finally found a large number of combustible ice on the Arctic seabed. In 1970s, the United States Geological drilling workers in the ocean, found a look like ordinary ice things, when it was pulled from the sea, the "ice" soon became a sparkling water, and those bubbles but accidentally lit, the gas bubble is methane. According to the study, these white ash, like dry ice, is a solid mixture of natural gas and water under high pressure and low temperature. The results of the present study show that it exists only in the submarine or the frozen soil zone. The appearance of pure natural gas hydrate is white, like ice and snow, it can be ignited directly like solid alcohol. Therefore, it is popularly known as combustible ice". [edit this paragraph] combustible ice causes combustible ice is gas molecules (alkanes) were water molecules in the crystal formation at the bottom of the sea temperature and under pressure. There are three basic conditions for the formation of combustible ice: temperature, pressure and raw materials. First of all, combustible ice can be generated above 0 degrees Celsius, but more than 20 degrees will decompose
Q:How to distinguish the use of natural gas and gas
Natural gas is generally composed of methane gas, mainly the production of specialized gas fields, such as coal, gas and oil is a brother, gas is their immediate boss
