Will gas be poisoned like gas?Gas poisoning due to the cause of carbon monoxide
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 6The main components of pyrolysis gas are as follows (%): 12, 5 ~ 7 hydrogen methane and ethane 5 ~ 7, 16 ~ 18, 0.5 ethylene propylene, propane, butane, 7 ~ 8, 4 ~ 0.2 - 5, with 5 or more carbon atoms from 2 to 3 of these hydrocarbons are easily liquefied hydrocarbons, will 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 light light blue flame, combustion process produces a large amount of heat (calorific value is about 92100 kJ/ m3 ~ 121400 kJ/m3)).The calorific value of the three gases: liquefied natural gas is the highest, followed by natural gas, city gas is low. The use of these three gases, such as the stove is not the same, can not be used directly
3 liquefied petroleum gas (LPG) is a by-product of oil refinery catalytic cracking and thermal crackingThe 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
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). A gas methane content can be as high as 99.8%. the other one is in addition to containing methane, gas containing more ethane, propane, butane, called wet gas (moisture), oil or natural gas.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 and blast furnace gas. Gas is mainly carbon monoxide; coke oven gas is rich in hydrogen, methane, and carbon monoxide; water gas is carbon monoxide and hydrogen.
