Introduction to liquefied petroleum gas:
LIQUEFIED PETRoleum Gas (LPG), one of the petroleum products, is a mixture of propane and butane, usually accompanied by a small amount of propylene and butthite. The main function: used as a raw material for petrochemicals, can also be used as fuel. LNE petroleum gas is mainly used as petrochemical raw materials, used for hydrocarbon cracking ethylene or vapor conversion synthetic gas, and can be used as industrial, civilian, and internal combustion engine fuel. Its main quality control indicators are evaporating residues and sulfur content, and sometimes control the olefin content. LNE oil gas is a kind of flammable substance. When the content of the air reaches a certain concentration range, it will explode when it encounters fire.
LNG is an oil tail gas left in the process of refining gasoline, kerosene, diesel, heavy oil and other oil products. Through a certain procedure, the oil tail gas is recycled and used to take pressure measures to turn it into liquid. Put in the pressure container, the name of liquefied gas comes from this. It is liquid in the gas cylinder. Once it flows out, it will vaporize into a combustible gas that is about 250 times the original volume, and it will easily spread. It will burn or explode when it encounters an open fire. LNE Petroleum is one of the petroleum products. English name liqufied petroleum gas, referred to as LPG. It is a colorless, volatile gas obtained by refining factory gas or natural gas (including the gas field accompanied by qi). The liquefied petroleum and gas obtained by refining plant gas is propane, acrylic, butane, butyl, and also contains a small amount of pentane, pentharne, and trace sulfurized compound impurities. The ingredients of liquefied gas obtained by natural gas are basically not olefins. 1. Shape and situation: LNE Petroleum and gas is mainly used as petrochemical raw materials, for hydrocarbon cracking ethylene or vapor transformation and synthetic gas, which can be used as industrial, civilian, and internal combustion engine fuel. Its main quality control indicators are evaporating residues and sulfur content, and sometimes control the olefin content. LNE oil gas is a kind of flammable substance. When the content of the air reaches a certain concentration range, it will explode when it encounters fire. LPG is mainly composed of propane (C3H8) and butane (C4H10). Some LPG also contain propylene (C3H6) and clutne (C3H8). LPG is generally obtained from petroleum and gas from oil and gas fields, refineries or ethylene plants. Compared with other fuels, LPG has the following unique advantages. ① less pollution. LPG is a hydrocarbon compound consisting of G3 (carbon three) and G4 (carbon four), which can be burned without dust. Applying in modern cities can greatly reduce pollution caused by coal and firewood in the past. ② High calories. The heat of the same weight LPG LPG is equivalent to twice the coal, and the liquid heat is 45 185 ～ 45 980kj/m3. ③ easy to transport. LPG is gas at normal temperature. Under a certain pressure or freezing to a certain temperature, it can be liquefied into liquid. It can be transported on land and water on land and water. ④ stable pressure. The pressure of the LPG pipeline user stove is unchanged, and the user is convenient. ⑤ The 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. The gas station can be stored with an LPG storage tank, and can be installed in the gas cylinder for users to use. Pipeline gas supply is implemented; even small bottles can be used to load butanane gas for hot pot fuels on the table, which is convenient to use. I due to the above advantages of LPG, it is widely used as industrial, commercial and civilian fuels. At the same time, its chemical composition determines that LPG is also a very useful chemical raw material, which is also widely used to produce various chemical products. 2. Machining process: LNE Petroleum gas is a by -product obtained by the refinery when crude oil catalytic cracking and thermal cracking.催化裂解气的主要成份如下(%)：氢气5-6、甲烷10、乙烷3-5、乙烯3、丙烷16rn-20、丙烯6-11、丁烷42-46、丁烯5-6, including 5-12 carbon atoms 5-12. The main ingredients of thermal fissure and qi are as follows (%): hydrogen 12, methane 5-7, ethylene 5- 7, ethylene 16-8, propane 0.5, acryline 7-8, butane 0.2, butthonne, 4-5 4-5 , 2 to 3 of hydrocarbons containing 5 carbon atoms. These hydrocarbon compounds are easy to liquefy, compressed them to 1/250-L/33, which only accounts for only 1/250-L/33, stored in high-pressure steel tanks. During the use of the liquefied gas tank valve, combustible hydrocarbon compounds Gas will enter the burner through the pipeline. After lighting, a light blue flame was formed, and a large amount of heat was generated during the combustion (about 92 100 kj/m3-121 400 kj/m3).
With the development of my country’s oil industry, many towns have begun to use liquefied petroleum gas for fuel. LPG gas is a by -product obtained by the refinery when crude oil catalysis and thermal cracking.
The main ingredients of catalytic cracking gas are as follows ( %):
hydrogen 5 ～ 6, methane 10, ethylene 3 ～ 5, ethylene 3, propylene, 16 ～ 20, acrylic, propylene, acrylic, 6 ～ 11, orbane 42 ~ 46, butylene 5 to 6, including 5 to 12 of hydrocarbons with 5 carbon atoms or above.
The main ingredients of thermal cracking qi are as follows ( %):
hydrogen 12, methane 5 ～ 7, ethylene 5 ～ 7, ethylene 16 ～ 18, propane 0.5, acrylic, 7 ～ 8, orbane 0.2, 4 ～ 5 of butyl, 2 to 3 containing hydrocarbons containing 5 carbon atoms or above. These hydrocarbon compounds are easy to liquefy, compressed them to 1/250 ～ L/33, which only accounts for only 1/250 ～ L/33, and stored in high -pressure steel tanks. During the use of the liquefied gas tank valve, combustible hydrocarbon compounds Gas will enter the burner through the pipeline. After ignition, a light blue flame was formed, and a large amount of heat was generated during the combustion (the heating value was about 92 100 kj/m3 ~ 121 400 kj/m3). It can also adjust the firepower according to needs, which is convenient and hygienic to use.
The liquefied petroleum gas is easy to use, but there are also unsafe hidden dangers. In the event of a pipeline leakage or a valve is not tight, the liquefied petroleum gas spreads to the room. When the content reaches the explosion limit (1.7%to 10%), it will explode when it encounters Mars or electric sparks. In order to remind people to discover whether the liquefied gas is leaked in time, the processing plant often mixes a small amount of sulfol or sulfein compounds with odor smells in liquefied gas. Once there is a liquefied qi leak, he smells this smell immediately. Take emergency measures
