Pipeline natural gas will not cause gas poisoning?
Liquefied petroleum gas (LPG) is a by-product of refinery catalytic cracking and thermal cracking.The main components of the catalytic cracking gas are as follows: (5) hydrogen, methane, ethane, ethylene, ethylene oxide, ethylene oxide, ethylene oxide, ethylene oxide, 10 ~ 6, ethylene, ethane, ethylene, propylene, ethylene glycol, ethylene glycol, ethylene oxide, ethylene oxide, ethylene, gas and water, the main components of the gas are as follows: (42) to hydrogen, methane, ethane, ethylene, ethylene oxide, ethylene oxide, ethylene, ethylene oxide, ethylene and propylene, the methane is from 5 to 5, ethane to ethylene, ethylene, ethylene oxide, ethylene and propylene, which is from 3 to 3, propane to propylene by ~ ~ ~ (s), propylene from 16 to 20, propylene from 6 to 11, butane from ~ (c) to ~ 46, butene from ~ (5) to about 6.The main components of the thermal cracking gas are as follows: (7): hydrogen, methane, 5 ~ ~ (s), ethane ~ ~ ~ ~ 7, ethylene, ethylene glycol, ethylene oxide, propylene glycol, propylene oxide, propylene glycol, propylene glycol, ethylene glycol, 5 to 18, propane, propylene, propylene glycol, propylene glycol, propylene glycol, 7 to 8, butane, butene, 4 to 5, containing more than 5 carbon atoms of hydrocarbons from 2 to ~ 0.2 ~ (3) ~ ~ ~ ~ ~ ~ ~ ~ (12). These hydrocarbons are easily liquefied, they are compressed to only the original volume of 1/250 ~ l/33, stored in the high pressure resistant steel tank, the valve open gas tank when used in flammable hydrocarbons gas goes through a pipe into the burner. After the formation of a light blue flame, combustion process produces a lot of heat (calorific value is about 92100 kJ/m3 ~ 121400 kJ/m3).The calorific value of the three gases: liquefied gas is the highest, followed by natural gas, city gas is lower. The use of these three kinds of gas stove is not the same, can not be directly used interchangeably.
2 because the gas source is different, there are different names: the dry distillation of coal and gas called coke oven gas; coal (or coke) in the case of incomplete combustion gas; if the carbon and water vapor in high temperature, can get water gas; there are quite a lot of combustible gas discharged from blast furnace in the name of blast furnace gas. Producer gas and blast furnace gas are mainly carbon monoxide; coke oven gas is rich in hydrogen, methane, and carbon monoxide.
First talk about the concept:1 natural gas refers to the 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). Don't a gas content of methane can be as high as 99.8%. 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.
