The urea solution for vehicles is an aqueous solution with a urea concentration of 31.8%-33.2%, which is in a transparent state. The raw materials for production are urea crystals and ultrapure water, which can be obtained by repurifying industrial urea. At present, the vehicle urea solution generally consists of 32.5% high purity urea and 67.5% deionized water. The SCR technology route is a commonly used automobile exhaust gas after-treatment technology. It optimizes the fuel injection and combustion process to control the generation of particles in the machine as much as possible. In the after-treatment process, the reducing agent urea solution is used to select nitrogen oxides. Catalytic reduction, the nitrogen oxides in the exhaust gas become non-polluting nitrogen and water, reducing NOx emissions, thus meeting the regulations related to heavy diesel vehicle emissions. China is one of the world's largest auto producers. In 2018, China's auto production and sales were 27.809 million units and 28.081 million units respectively, of which the production and sales volume of heavy-duty diesel vehicles accounted for about 18%. Heavy-duty diesel vehicles are the main source of pollutants emitted by motor vehicles. Therefore, the existence of a large number of heavy-duty diesel vehicles will inevitably pose a long-lasting threat to environmental pollution. However, heavy-duty diesel vehicles cannot be completely replaced in the short term. Therefore, in the face of the “Limited emission limits and measurement methods for heavy-duty diesel vehicles (China’s sixth phase)†to be implemented from July 1, 2019, in order to meet the standard requirements for vehicle emissions, the market demand for automotive urea will increase rapidly. According to the research report on market market monitoring and future development prospects of China's automotive urea industry in 2019-2023, the demand for global automotive urea was 41.09 million tons, of which 9.16 million tons were China. The global share is 22.3%. In addition, the United States, Japan, Europe and other countries and regions have a large number of cars, and the popularity of SCR technology routes is high, which is also the main demand market for global automotive urea. In the Chinese market, the demand for automotive urea is mainly concentrated in East China, South China, Northeast China and other regions with high automobile production and sales volume, and the demand ratio is 68%. Due to the large demand space for vehicle urea and the low barriers to entry in the automotive urea industry, the number of enterprises conducting research on automotive urea products has increased in recent years, and the production capacity and production technology of the industry have increased significantly. The gap in the enterprise has gradually narrowed. At present, the main manufacturers in China's automotive urea industry include Sichuan Meifeng Jialan Environmental Protection Technology Co., Ltd., Jiangsu Kelansu Automotive Environmental Protection Technology Co., Ltd., and Yitong Environmental Protection Technology (Putian) Co., Ltd. In 2018, China's automotive urea industry capacity was 8.6 million tons. Since vehicle urea has a certain sales radius, the enterprises in the industry mainly concentrate on competition in a certain region, mostly regional brands. The market concentration of China's automotive urea industry is not high. The aggravation of smog has made our government pay more and more attention to environmental protection. The intensive introduction of vehicle emission standards has brought great pressure on exhaust gas detection for major car owners, especially the upcoming National Sixth Standard. New think industry analysts believe that vehicle urea is a common product of diesel exhaust gas treatment system, and the implementation of the national six standard will certainly promote the substantial increase in demand for automotive urea.
