Product Description

Diesel Exhaust Gas Treatment Fluid

Diesel exhaust gas treatment fluid (DEF) is mainly used for carrying SCR catalytic reduction system, the National IV and National V trucks and passenger diesel engines.The car with urea solution is used as a waste material cut diesel vehicles, the ingredients are of high purity water solution containing 32.5% urea, reduction by selective catalysis, the emission of nitrogen oxide (NOX) reduction of nitrogen and water, to reduce air pollution. It is a very environmentally friendly automobile exhaust gas treatment product. Products meet the national standards, as well as the European Union standards and international quality certification.

DEF is stored in a tank on board the vehicle, and injected into the exhaust stream by a metering system. The injection rate depends on the specific after-treatment system, but is typically 2-6% of diesel consumption volume. This low dosing rate ensures long fluid refill intervals and minimises the tank's size (and subsequent obtrusion into vehicle packaging space). An electronic control unit adjusts the addition of fluid in accordance with such parameters as engine operating temperature and speed.

Working Principles
Diesel engines can be run with a lean burn air-to-fuel ratio (overstoichiometric ratio), to ensure the full combustion of soot and to prevent them exhausting unburnt fuel. The excess of air necessarily leads to generation of nitrogen oxides (NOx), which are harmful pollutants, from the nitrogen in the air. Selective catalytic reduction is used to reduce the amount of NOx released into the atmosphere. Diesel exhaust fluid (DEF) from a separate tank is injected into the exhaust pipeline, where the aqueous urea vaporizes and decomposes to form ammonia and carbon dioxide. Within the SCR catalyst, the NOx are catalytically reduced by the ammonia (NH3) into water (H2O) and nitrogen (N2), which are both harmless; and these are then released through the exhaust.

DEF is a 32.5% solution of urea, (NH2)2CO. When it is injected into the hot exhaust gas stream, the water evaporates and the urea thermally decomposes to form ammonia and isocyanic acid.
The overall reduction of NOx by urea is:
2 (NH2)2CO + 4 NO + O2 → 4 N2 + 4 H2O + 2 CO2 and
2 (NH2)2CO + 3 NO2 → 2 1⁄2 N2 + 4 H2O + 2 CO2

Company profile:
Mingshuo Environmental Technology Group Co., Ltd. was founded in 2004. The company is located at No.8 West Ring Road, Yeyuan Street, Linqu County, Weifang City, Shandong Province. The registered capital is 88 million yuan, covering an area of more than 100 mu. Mingshuo is positioned in the R&D, manufacturing and sales of high-end environmental protection complete sets of equipment, and is also a project system integration and operation service provider.
The company's products are generally divided into two series: desulfurizer, desulfurization equipment and biogas equipment. Desulfurizer and desulfurization equipment are mainly used for the treatment of sulfur-containing gas in users such as biogas, natural gas, oil associated gas, shale gas, chemical fertilizer, coking, steel mills, petroleum refining and pharmaceutical industry; The biogas equipment is mainly used for the treatment of livestock manure, kitchen waste, organic waste, straw, sewage and other organic wastes, so as to realize high-value utilization and turn waste into wealth. Organic wastes are treated by biogas equipment to become three biogas, namely biogas, biogas residue and biogas slurry. Biogas can not only be used for power generation, heating, supplying households, but also for purifying natural gas. The biogas slurry can be used as organic fertilizer.

Company qualification:
The company has passed the 'Trinity' management system certification of quality, environment, occupational health and safety, and has the professional construction qualification of environmental protection engineering, the construction safety production license, and the D1 and D2 pressure vessel qualification. Obtained 28 patents for inventions and utility models, and participated in the formulation of national standards for biogas desulfurization equipment. It is a high-tech enterprise in Shandong Province, Weifang Desulfurization and Denitrification Engineering Laboratory and Weifang Biogas Equipment Engineering Technology Research Center. It has the right to import independently, and has won the titles of "China Green Products", "Excellent Products of China Renewable Energy and Energy-saving Products Technology Expo" and "China Famous Brand".

Sales market:
With reliable quality and excellent service, "Mingshuo" brand equipment sells well all over the country, and is exported to Asia, Africa, America, Europe and Oceania, and exported to more than 20 countries and regions such as Malaysia, Japan, Uzbekistan, Indonesia, Iran, Thailand and Maldives.

Partners:
The Group has long-term cooperation with Sinopec, PetroChina, COFCO, CSIC, China Nengjian, Beijing Drainage Group, Yingfeng Environment, Huadian Group, Weichai Group, etc. It is a member unit of China Biogas Society, a member unit of china association of rural energy industry, China Biogas Research Institute, Process Research Institute of Chinese Academy of Sciences, Planning and Design Institute of Ministry of Agriculture, Tsinghua University, Shandong Chemical Planning and Design Institute, Agricultural University, Qingdao University of Science and Technology and other research institutes, and a cooperative unit with German national biogas expert Joe.

Company development philosophy:
Environmental protection is the theme of development in the 21st century, and the treatment of organic waste and air pollution is very important. It is our unremitting pursuit to optimize and upgrade the quality of environmental protection equipment, ensure the long-term safe operation of environmental protection projects, make Mingshuo products spread all over the world, make resources circulate infinitely, create a cleaner world and create the greatest value for the society. With the concept of "cherishing the limited, creating the unlimited", we will build an international leading system service provider for environmental protection and new energy industry.
