Q:What are the uses of natural gas?

Natural gas is stored in underground porous rock, the main component of methane, the proportion of 0.65, lighter than air, with colorless, tasteless, non-toxic characteristics. Natural gas companies are in accordance with the provisions of the government to add odor agent (four thiophene), in order to sniff the user identification.If the concentration of natural gas in the air in the range of 5% to 15%, in case of open flame can occur, the concentration range is the explosion limit of natural gas. The explosion in a short time to produce high pressure, high temperature, its destructive power and risk are great. 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:Natural gas toxic how should pay attention to

First of all, you need to know the difference between gas and natural gas.The main component of natural gas is methane and hydrogen, colorless, tasteless, high calorific value, full combustion, no impurities. Liquefied petroleum gas is the main component of four carbon below the hydrocarbon, colorless, tasteless, calorific value lower than natural gas, there are certain impurities. For a long time the use of liquefied petroleum gas kitchen cooking utensils, cooking stoves appear to have a layer of oil, which is liquefied petroleum gas combustion emitted by some of the organic matter. Coal gas is mainly produced by coking gas, it is the main component of carbon monoxide, but also contains a small amount of hydrogen, such as methane, although it is colorless, tasteless, then, why the toxic gas?

Q:How much is a natural gas in 2014?

Is the answer as long as the answer to a word, if it is, it can only use 'expensive' to describe the word.

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.

Q:The working principle of the gas refrigerator?

The gas fuel used in the gas refrigerator can be natural gas, artificial gas, liquefied petroleum gas, and the likeThe refrigeration temperature is adjusted by adjusting the intake quantity automatically.The biggest advantage of the gas refrigerator is not to use electricity, especially for the occasions where there is no electricity. And because it's notMechanical movement and friction of parts, so no noise. But it uses a refrigerant - ammonia, toxic, and easy to useBurning,

Q:How many kinds of natural gasWhat are their uses

The distribution of natural gas in petroleum geology, usually referred to as oil and gas fields. It is composed mainly of hydrocarbons and contains non hydrocarbon gases. The broad sense of natural gas refers to all the natural gas generated in the earth's crust, including oil field gas, gas field gas, mud volcanic gas, coal support and bio gas generation. According to the phase state of natural gas in the underground, it can be divided into free, dissolved, adsorbed and solid state. Only the free form of natural gas can be formed by accumulation of natural gas.

Q:How to do natural gas leakage

If you find a gas leak, to keep calm, take the right solution to avoid the explosion. First of all, the gas valve should be closed immediately, blocking the gas source; and quickly open the doors and windows ventilation, action should be kept in mind, so as not to cause the explosion caused by heavy metal impact. Can not be anxious panic, if accidentally hit the metal objects indoors, may also produce sparks and explosion

Q:Is steel filled with gas or natural gas?

Natural gas is from gas containing methane and other alkanes by gas, according to the content of methane in natural gas and other hydrocarbon, natural gas will be divided into two types: one is called methane containing dry gas (dry gas), usually containing methane 80 ~ 99% (in volume). The other is in addition to containing methane, but also contains more ethane, propane, butane gas, known as wet natural gas (moisture), or multi oil natural gas.

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:Natural gas can not be renewable

The benefits of renewable energy: 1. The development and utilization of renewable energy is the basic requirement for the implementation of Scientific Outlook on Development, the construction of a resource-saving society and the realization of sustainable development. Adequate, safe and clean energy supply is the basic guarantee for economic development and social progress. China has a large population, low per capita energy consumption, large energy demand growth, energy supply and economic development is very prominent contradictions. To solve the energy problem of our country fundamentally, continue to meet the needs of economic and social development, protect the environment and achieve sustainable development, in addition to vigorously improve energy efficiency, accelerate the development and utilization of renewable energy is an important strategic choice, but also to implement the basic requirements of Scientific Outlook on Development, to build a resource-saving society.
