Brief introduction of light hydrocarbon gas Section 1: Raw material source of light hydrocarbon gas 1. C4-C 10 liquid hydrocarbon mixture, a by-product associated with oil and gas field exploitation. Its names vary from place to place, including light oil, light oil, light naphtha and light gasoline. This part of the oil is generally sold by the third production company of the production unit or a diversified company. 2. The associated by-product obtained from the wet natural gas purification plant mainly consists of C5-C8 liquid hydrocarbon mixture, which is called condensate oil. Third, the by-product "topping oil" produced by petrochemical plants is a liquid hydrocarbon mixture mainly composed of pentane. Yangzi Petrochemical, Guangzhou Petrochemical, Maoming Petrochemical and other petrochemical enterprises all have supplies. C5 produced by refinery is a liquid hydrocarbon mixture with pentane as the main component. China's liquid light hydrocarbon reserves are equivalent to the output of liquefied petroleum gas (LPG). As a primary energy to replace secondary energy such as liquefied petroleum gas, diesel oil and electric power, it has important strategic and practical significance for optimizing China's energy structure, improving energy utilization efficiency, and being a beneficial supplement to the uneconomical market of natural gas input and output. Section II: How to make light hydrocarbon gas The gasification equipment developed by light hydrocarbon company takes petroleum, chemical by-products, liquid light hydrocarbon C5 and liquefied petroleum gas residue as raw materials (impurities need to be removed). Without adding any additives, a certain amount of air is added to the light hydrocarbon gas generator at normal temperature and low working pressure, which is mixed to make light hydrocarbon gas meeting national standards and then transported to residents through pipelines. Section III The raw materials actually supplied by the light hydrocarbon gas raw material distribution company are: 1, Bohai Oilfield, Donghai Oilfield, Nanhai Oilfield, Daqing Oilfield, Jilin Oilfield, Liaohe Oilfield, Jidong Oilfield, Dagang Oilfield, Huabei Oilfield, Karamay Oilfield, Tuha Oilfield, Tarim Oilfield, Qinghai Oilfield, Yumen Oilfield, Changqing Oilfield, Shengli Oilfield, Jiangsu Oilfield and Jiangsu Oilfield. Zhongyuan Oilfield, Nanyang Oilfield, Dianqiangui Oilfield, Tiandong Oilfield 2, Guangzhou Petrochemical, Maoming Petrochemical, Jiujiang Petrochemical, Zhenhai Petrochemical, Yangzi Petrochemical, Dagang Petrochemical, Beihai Petrochemical, Lanzhou Petrochemical and Jingmen Petrochemical. Section IV: The application scope of light hydrocarbon gas can be used as the gas source of public utilities users such as cooking, heating, bathing, hotels, restaurants, staff canteens, catering industry, etc. It can also be used as a gas source for small industries such as glass products, medicine, food, textiles and building materials. Section 5: Advantages of light hydrocarbon gas 1. Safe and reliable, this light hydrocarbon gas avoids the long natural gas, coke oven gas and pipe network, and is vulnerable to irresistible threats of natural disasters and restrictions of road excavation. It solves the defects of high pressure, easy leakage, easy poisoning and easy explosion of natural gas, coke oven gas, water gas and liquefied gas. The transmission and distribution pressure of natural gas is 3.2 kg per square centimeter, the transmission and distribution pressure of gas is 3-4 kg per square centimeter, and the pressure of liquefied gas tank is 4-5 kg per square centimeter. The operating pressure before this gas stove is only 0.023 kg per square centimeter, which is ten times lower than that of liquefied gas. Low air pressure is very important for safety. Under the condition of low pressure, the following four safety guarantees are developed and installed: 1, and an indoor tempering device is installed. Once a fire breaks out in a room for any reason, as long as the snake skin tube is burned, the pressure of the fire will definitely exceed 0.5 kg per square centimeter. As long as it reaches 0. 15-0.3 kg per square centimeter, the indoor gas will be automatically turned off, and it will not cooperate with the fire extinguishing or increase the fire. 2. The gas outlet of the gas supply station is also equipped with tempering device, so the fire will not enter the pipe network and gas supply station. 3. In case of irresistible natural disasters, the station building management personnel can immediately close the gas supply valve and gas-making power supply to ensure the safety of users. 4. There is also a safety measure for gas equipment, and the gas supply station can know the gas leakage in advance. Once the user or the leaking gas supply station of the gas pipeline network can get the alarm first, the equipment of the gas production station will start to stop working. 2. Economical natural gas and coke oven gas are only used in large and medium-sized cities in China. Due to the limitation of geography, resources and financial resources, most cities and counties have not used natural gas and coke oven gas. Because natural gas and coke oven gas are far away from the city, coupled with the long transmission and distribution network, the urban road excavation scale is large, coupled with coke oven gas, natural gas management is complex and the investment is large. Light hydrocarbon gas has less investment, less land occupation, no damage to urban construction, and can save gas cost 10%- 15%, thus benefiting users. 3. It is convenient and sanitary. The gas-making raw material of this technology adopts petroleum by-product C5, also called light hydrocarbon, or naphtha, petroleum ether, light oil, etc. Through scientific research, scientific gas-making equipment and devices are applied to civil life and industry. Light hydrocarbons are non-toxic, tasteless, smokeless and pollution-free, and have good combustibility and high calorific value. It is a convenient, hygienic, environment-friendly and energy-saving gas, which can effectively utilize renewable energy, turn waste into treasure and benefit mankind. It is embodied in: 1, which solves the inconvenience of people's lives and reduces the labor intensity in people's lives. 2. The problem of government-led environmental pollution control has been solved. 3. Compared with liquefied gas, it avoids the danger of high gas pressure and easy explosion after aging, and light hydrocarbon gas provides life and property safety for residents. 4. Compared with coal users, the coal piles and mounds in front of the door have been cleaned up. Beautify people's indoor and outdoor living environment. 5. The gasification rate in operation is 100%, and the gas price is lower than that of liquefied gas, which reduces the economic burden of residents and does not require government subsidies. 4. Environmental protection and energy saving The raw material of this gas is a by-product of gasoline, so it can replace the old tradition of burning coal, saving time and labor, saving resources, protecting the balance of the natural environment and benefiting future generations, which is of great significance. 5. Advanced technology is embodied in the following aspects: scientific rigor, non-toxic, tasteless, multi-purpose, time-saving and labor-saving, inexpensive, convenient and flexible, safe and environmentally friendly, and the technology has reached the domestic leading level. Section VI: Application and development prospect of light hydrocarbon gas At present, natural gas, liquefied petroleum gas and diesel oil are the main clean fuels used in China and even some developed countries in the world. Natural gas and liquefied petroleum gas are very valuable chemical raw materials with high added value after deep processing. Because there is no good alternative energy, they can only be burned as ordinary fuels. In today's increasingly tight world energy supply, burning it as ordinary fuel is a waste of limited resources. Therefore, the State Council proposed that "implementing the policy of paying equal attention to development and saving, improving the energy structure and layout, relying on scientific and technological progress, and developing alternative gas sources according to local conditions, so as to improve the level of urban modernization, develop the economy, reduce environmental pollution and improve urban quality, which will be the primary task of government departments at all levels in the future. Using light hydrocarbon gas as alternative fuel can solve the shortage of oil resources in China, alleviate the contradiction between oil supply and demand, accelerate the adjustment of energy structure in China, promote the optimization of energy structure and strengthen the comprehensive utilization of resources, which is an effective measure for sustainable economic and social development. With the rapid development of China's economic construction and the acceleration of the construction of small towns and new countryside, the demand for clean energy will increase day by day, which also provides a broad market for the application of light hydrocarbon gas, which contains huge business opportunities and is the most valuable new energy project in 2 1 century. After exploration and practice, a company in China successfully applied C4-C 10, a by-product of oil and gas field exploitation, to gas fields. Replacing diesel as secondary energy and using natural gas and liquefied gas with higher value can change and optimize China's energy structure, which not only has higher economic and environmental benefits, but also has far-reaching energy strategic significance. Therefore, it is certain that the application of light hydrocarbon gas has huge market space and good development prospects in China.
