According to 1997 statistics to build gas station company in Henan, China's automobile production was 1.578 million. Predicting the end of 2000, China's auto output reached 2.7 million. With the continuous improvement of people's living liquefied gas, cars in every household may gradually become a reality. Beijing existing car for 1.338 million. January to October 1998 statistics liquefied natural gas storage tanks, a net increase of 140,000 cars on Beijing, which reached 130,000 purchase. Increase the number of cars is not difficult to understand the results from urban air pollution. Some automobile emissions account for the total number of the city's pollution of air pollution more than 60%, many people believe that Beijing's air pollution comes mainly from vehicle exhaust emissions. Therefore, the city gas is a great market. City gas vehicles mainly useful as fuel gas, which has compressed natural gas vehicles (CNGV), liquefied natural gas vehicle (LNGV). The main fuel is natural gas, its composition is methane. There liquefied petroleum gas as fuel cars (LPGV), mainly LPG is a mixture of propane and butane. From foreign sources, all three cars LPGV gas accounted for 82%, 17% natural gas vehicles, methanol as fuel cars accounted for 1%. Other markets to develop LPG butane separated and can be used as a portable butane lighter gas furnace as fuel. Because Freon and CFCs can cause ozone depletion, caused concern. Therefore, refrigeration systems, particularly for household refrigerators and freezers have increased the use of isobutane (2-methylpropane), instead of the use of freon as a refrigerant. Also isobutane also add in sprays, instead of CFCs. Compared with developed countries the gas station, gas station consulting, China's LPG consumption level is still low, improving the rapid growth of China's economy and people's quality of life of urban and rural, need more high-energy. LPG consumption center will expand Guangdong Province to the Yangtze River Delta, Yangtze River region, the Bohai Bay and the Southwest, LPG consumption in these areas will also be spread from urban to rural areas. Although the implementation of the national natural gas project, have an impact on the market of liquefied petroleum gas, natural gas, but the main target is the replacement of existing gas pipeline users, with LPG in chemical raw materials, automotive fuel, gas cutting fuel and refrigerant, aerosol sprays development and application of other industries, and liquefied petroleum gas in the next period of time, there is still a good market.
