fireproof insulation blanket for lng cryogenic storage

Cryogenic Insulation blanket

The insulation blanket is developed based on our research,

this product can adequately consider user's actual site

application needs. In order to satisfy requirements from

different mediums and different structures of cryogenic

vessels are composited, cut and finally stitched together.

What's more, the composite insulation materials will be

pre-perforated according to the vessel's structure, and in the

meantime some supplementary are also provided.

All these measures contribute to rapid placement of multilayer

insulation on tanks and guarantee the insulation performance.

Q: 1 cubic meters of natural gas is equal to how much MBTU: 1MBtu (mmbtu) = CF (1000 cubic feet) is 28.3 m3 (M3)Example 1: U.S. natural gas vehicle gas price of $8.04 /MBtu, equivalent to RMB

Q: What is the density of liquefied petroleum gas: Therefore, the density of natural gas used in practice is uncertain, which is related to the temperature, pressure and composition of natural gas. Under normal circumstances, the density range is 0.55 - 0.90kg / m3.

Q: What are the by-products of natural gas: The chemical composition and physical and chemical properties of natural gas vary from place to place, the main component is methane, but also contains a small amount of ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc.. No hydrogen sulfide when the colorless and odorless flammable and explosive gases, density of 0.6 ~ 0.8g/cm3, lighter than air.

Q: How to do gas pipe leakage: 1 easy to leak place: hose, interface, gas meter, plug valve, ball valve.2 when the suspect a gas leak, the leak using the following method: one of the optional soap, washing powder, detergent three, and water to form a liquid soap onto the hose, gas appliances, gas meter, plug valves, ball valves, especially at the interface, the bubble bulging part is the leakage point. The eyes, ears, hands touch, smell with the leak. (Note: do not use open flame leak.)

Q: What is the difference between a gas producer and a cold gas?: Its advantages are:1) the system is simple, less investment, only about 60% of the same scale cold gas station2) can make full use of the sensible heat. The temperature of 450-550 DEG C Jehol tar up from the furnace gas temperature, it is good for high temperature heating furnace, steam can also tar directly with hot gas to the furnace combustion, can significantly increase the total calorific value of gas. So hot gas calorific value than cold bituminous coal the gas is 15% higher.3) has the advantages of simple equipment, convenient operation. Hot gas stations generally use only rough cyclone dust, do not need washing gas purification equipment, such as vertical washing tower, electric detarrer, also do not need equipment for gas pressure, make the management more convenient.4 light pollution. Because the gas does not need to wash, so there is no waste gas produced by the washing wastewater containing phenol, so you do not have to carry out water treatment, little harm to the environment5) low production cost, less staff

Q: What is the density of natural gas: 1 density and relative densityUnder 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 0.62.2 ignition temperatureThe ignition temperature of methane is 540.3 combustion temperatureThe theoretical combustion temperature of methane is 1970.The theoretical combustion temperature of natural gas can reach 2030.

Q: What are the advantages of natural gas as a source of energy compared with coal: Characteristic：Natural gas is one of the more safe gas, it does not contain carbon monoxide, but also lighter than air, once the leak, will immediately spread upward, not easy to accumulate the formation of explosive gas, high security.The use of natural gas as an energy source, can reduce the amount of coal and oil, thus greatly improve the problem of environmental pollution; natural gas as a clean energy, can reduce sulfur dioxide and dust emissions of nearly 100%, a 60% reduction in carbon dioxide emissions and NOx emissions by 50%, and helps to reduce the formation of acid rain, relieve the greenhouse effect and fundamentally improve the quality of the environment.

Q: The gas in the gas tank is used up. What's wrong with the water?: Oh ~ upstairs to say another reason. I know there's an explanation, the gas tank is used in high density gas compression, the compression of a substance needed to prevent gas in high density compression due to the expansion of the explosion of molecular collision friction, when the gas is exhausted, the substance is left in the bottle, hot and cold temperature and other factors after sublimation into liquid.

Q: Civil gas tank fire, the best way to fight fire?: How to do the gas tank fire in the face of a gas tank at home, should call the police as soon as possible, and timely evacuation of the crowd. If the gas tank heating time is short, the gas tank valve should be closed immediately, and promptly cut off the power supply, if the heating time is longer, do not immediately close the valve or the use of cold water poured out, lest cause explosion. To wait for firefighters arrived in a safe place, after the first uniform cooling of the gas tank, and then fire. The fire gas tank can not be poured to the ground, because the cylinder is burning on the ground, no matter whether the outlet is equipped with a pressure reducing valve, the explosion does not occur. While lying in the cylinder through the gas bottle out of a 250 expansion 300 times, produce high temperature combustion, resulting in cylinder explosion. Accidentally knocked down the cylinder, it should be erected in time.
