To reduce the pollution caused by automobile exhaust to the atmosphere, our country will be fully implemented IV emission standards. With the date of implementation of China IV standards gradually approaching, urea traditional chemical products are expected to breathe new vitality. In fact, in Europe, in 2006 it has begun to implement this policy. European diesel exhaust treatment fluid called Adblue. In the United States, beginning in 2010, with the implementation of standards EPA2010, also increased the overall automotive urea solution application implementation efforts in the United States, diesel exhaust treatment liquid called DEF (Diesel Exhaust Fluid). The main representatives BlueDEF like. However, in China, for the production of diesel exhaust treatment fluid is still an emerging industry. Currently the largest amount of foreign European market, sales of urea during the 2006 European network has been formed, there are two forms of retail outlets and pumping urea. Currently gas stations in the whole of Europe can buy car urea. In 2010 its market demand has reached 3 million tons. Domestic demand: China's 12th Five-Year Plan requires nitrogen oxide emissions by 10%. 2011 to 2015, the state has promulgated the fourth, fifth stage vehicle fuel national standards, and heavy-duty diesel vehicles using SCR technology stock, Adblue is an essential accessory products. China is the world's second largest auto market, where heavy truck fleet of over 2300 vehicles. Thus, the vehicle has a large market scale urea. According to the China Association of Automobile Manufacturers, responsible person, the next few years, automotive urea market will experience a development and growth process. Truck assume annual sales of 70 million units, per country, four standard annual consumption of heavy trucks 2 tons of urea car, then car market increased demand for urea will be explosive. If in the future the full implementation of China IV diesel standard, in theory, the annual consumption of automotive urea will reach 10 million to 15 million tons. Customers buy cars that are nothing to worry about the financial burden with the urea solution would, because the use of vehicle fuel consumption by 5 percent, fuel costs savings to buy car fully meet the needs of the urea solution. Save money at the same time, enhance the power, but also energy-saving and environmental protection, threefold.
