If liquefied petroleum gas is one of the petroleum products. English name liqufied petroleum gas, referred to as LPG. A colorless, volatile gas. The liquefied petroleum and gas obtained by the refining plant is propane, acrylic, butane, butthite, and also contains a small amount of pentane, pentharne and trace sulfur. The ingredients of liquefied gas are basically not olefins.
1. Stocks and conditions: LNA petroleum gas is mainly used as petrochemical raw materials, for hydrocarbon cracking ethylene or vapor transformation, synthetic gas It can be used as industrial, civilian, and internal combustion engine fuels. Its main quality control indicators are evaporating residues and sulfur content, etc., and sometimes control the olefin content. LNICO is a kind of flammable substance. When the content of the air reaches a certain concentration range, encounter The bright fire is the explosion.
The LPG is mainly composed of propane (C3H8), butane (C4H10). Compared with other fuels in the oil gas gas gas gas gas gas gas gas and gas gas, it has the following unique advantages.
① less pollution .lpg is composed of G3 (carbon three) and G4 (carbon 4) The hydrocarbon compounds can be burned all, no dust. Applying in modern cities can greatly reduce pollution caused by coal and firewood in the past.
The heat of LPG is equivalent to twice the coal, and the liquid heat is 45 185 ~ 45 980kj/m3.
③ easy to transport .lpg under normal temperature and constant gas, under a certain pressure or at a certain pressure, or at a certain pressure, or at a certain pressure, or at a certain pressure, or at a certain pressure, or at a certain pressure, or at a certain pressure, or at a certain pressure, or at a certain pressure Frozen to a certain temperature can be liquefied into liquid. You can use train (or car) tank cars, LPG ships to transport on land and water.
④ Pressure stable .lpg pipeline user stove’s stove is unchanged, users use Convenient.
⑤ Storage equipment is simple and the supply method is flexible. Compared with the production, storage and supply of urban gas, the storage equipment of LPG is relatively simple. For users in the gas cylinder, you can also implement pipeline gas supply through gas distribution stations and supply networks; even small bottles can be used with small bottle gas, used as hot pot fuels on the table, easy to use.
Because LPG has the above advantages, it is widely used as industry, commercial and civil fuel. At the same time, its chemical composition determines that LPG is also a very useful chemical raw material, so it is also widely used to produce various chemical products.
2. Processing process: Ip oil gas is obtained when the refinery is catalyzed and thermal cracking A by-product. The main ingredients of catalytic cracking gas are as follows (%): hydrogen 5-6, methane 10, ethylene 3-5, ethylene 3, alkane 16-20, acrylic 6-11, butane 42-46, butthonne 5-5- 6, hydrocarbons containing 5 carbon atoms 5-12. The main ingredients of thermal cracking qi are as follows (%): hydrogen 12, methane 5-7, ethylene 5-7, ethylene 16-8, propane 0.5, acrylic 7, 7 -8, orbane 0.2, butyl 4-5, hydrocarbons containing 5 carbon atoms 2 ~ 3. These hydrocarbons are easy to liquefy, compressing them to 1/250-L/33, which only occupy the original volume of 1/250-L/33 , Stored in a high -pressure steel tank, unscrewed the valve of the liquefied gas tank during use, and the combustible hydrocarbon compound gas will enter the burner through the pipeline. After lighting, it will form a light blue flame. The heating value is about 92 100 kj/m3-121 400 kj/m3).
3. The purpose of liquefied gas With the development of the petrochemical industry, liquefied petroleum gas is used as a chemical industry as a chemical industry Basic ingredients and new fuels have become more and more valued by people. In terms of chemical production, liquefied petroleum gas has been separated from ethylene, acrylic, butyl, and clarne. Production of products such as medicine, explosives, dyes, etc. with liquefied petroleum gas as fuel. Due to its high heat value, smoke -free, carbon -free residue, it has been widely used in people’s life fields. In addition, liquefied petroleum gas is still used for Cut the metal, used for baking of agricultural products and baking industrial kiln.
. For non -ferrous metal smelting There is no pollution, and the liquefied petroleum gas has these conditions. After the liquefied petroleum gas is heated and gasified, it can easily introduce the smelting furnace to combust. The copper smelting process of Bolong refining furnace replaces the original gas combustion technology, reduces the harm of impurities such as sulfur and phosphorus, and improves the quality of copper. Various industrial kiln and heating furnaces have always been mainly coal -burning, which not only causes waste of energy, but also the discharged smoke is also seriously polluted by the environment. To this end, the relevant state departments proposed that China’s energy sources in the future are: Optimizing the energy structure to optimize the energy structure , Establish a world -class clean, safe, and efficient energy supply system, and establish a promotion mechanism for energy technology development. In order to meet the requirements of this task, many industrial kiln and heating furnaces are used to use liquefied petroleum gas fuel, such as liquefied petroleum and gas. Come to burn porcelain tiles; use liquefied petroleum gas baking and rolled sheets, etc., which not only reduces the pollution of air, but also greatly improves the quality of the product.
. N According to the announcement of China’s urban environment in 2000, of the 338 cities monitored, 63.5%of cities that exceed the national atmospheric quality secondary standards, of which 112 are more than three levels. In this way, China’s air pollution has been transformed from industrial waste, cigarette gas -type gas to optical smoke type, and automobile emissions in large cities have become one of the main sources of pollution of atmosphere. At present, about 70%of the sources of urban air pollution come from the automotive exhaust emissions of the automobile. In order to solve this problem, since the end of the 20th century, major and medium cities in China have successively built automotive gas stations to replace gasoline for car fuel with liquefied petroleum gas. Another major development direction of liquefied petroleum and gas use.
. Residents ‘life combustion The residents’ living liquefied petroleum gas mainly has two ways of pipeline transportation and bottle supply. Transportation: Pipeline transportation methods are mainly concentrated in large and medium cities. The residents’ homes are used. At present, many cities have realized this form of supply .2, installation supply: The bottle supply is to distribute liquefied petroleum gas from a sealing steel cylinder to the storage station to various households, as the source of gas supply for family cookers, as the source of gas supply for family cookers It originated in the early 1960s. It was first used in the refinery and several industrial cities. It has developed in rural areas and rural areas. For some, some townships have an average of more than 2. In this shows that the scope of the use of liquefied petroleum and gas is getting wider and wider, the amount of use is getting larger and larger, and the development is faster. The publicity and learning of petroleum and gas knowledge to ensure the safe use of liquefied petroleum and gas is very necessary and urgent.
. The related knowledge of liquefied petroleum gas n With the development of China’s oil industry Many cities and towns have begun to use liquefied petroleum gas for fuel. It liquefied petroleum and gas is easy to use, but there are also unsafe hidden dangers. In case the pipeline leakage or valve is not tight, the liquefied petroleum gas spreads to the room. When reaching the explosion limit (1.7%to 10%), an explosion will occur when encountering Mars or electric sparks. In order to remind people to find out whether the liquefied gas is leaked in time, a small amount of sulfurnol or sulfurnol or sulfur or odor is often mixed with liquefied gas. Sulfin etherial compounds. Once there is a liquefied qi leak, it will smell this smell immediately. Emergency measures.
