Vehicle urea protects the country's four emission standards

On July 1, in a number of voices of questioning and arguing, 18 cities including Nanjing, Qingdao and Chengdu announced the implementation of the Fourth National Standard as scheduled. Although it will take some time for the National IV policy to be fully implemented nationwide, the pacesetter has already taken the most difficult step. As long as everyone has enough courage and perseverance, it will surely be able to cross the national 4th roadblock. The password for "implementation of State IV" has already been issued. What problems are involved in the specific implementation? Due to the influence of national conditions, oil products and other factors, the main line used in the upgrading of China's National IV is SCR. In the SCR technology route, adding vehicle urea is the key to achieving the national IV emission standards. As a result, the status quo of domestic vehicle urea will determine the specific effect of the implementation and implementation of the National IV.

Car urea promotes difficult and flexible filling

July 1, 2013 was a very special moment for the commercial vehicle industry. As you can see, the trucks of the country’s third national and second-country trucks loaded with goods continuously pass through a junction marked with a traffic light. It is said that starting from July 1, traffic lights will turn red, and all the commercial vehicles that fail to meet the national standards will be able to The car will be unable to pass. Manufacturers, supporting companies, oil companies and related product manufacturers are all staring at this traffic light, hoping to take action in the first time of change, layout the market. The “Rookie” car urea in the market, which is closely linked with the National IV, has attracted many attention.

Then, is the essential vehicle urea solution for the National IV diesel vehicle convenient for drivers to add at any time? In the implementation of the National IV problem, the imperfect vehicle urea filling equipment has been listed as one of the four “hurdles” hindrance by the industry. Domestic vehicle urea solution has no perfect supply system at present, meeting the timely addition of urea solution to vehicles is still a big problem. Establishing a complete urea solution supply system to ensure the normal supply of urea solution needs to be solved.

In the recent investigation activity of the Central Media “State IV Implementing Industrial Readiness”, the reporter visited the Meifengjia Blue Plant Area. It is understood that the current vehicle urea solution products of Meifeng Jialan have 10L and 20L small packages and 1TIBC. Ton barrel packaging. For the promotion of the product, Wu Jiangtao, general manager of Sichuan Meifengjialan, said that the current promotion of domestic vehicle urea is mainly based on small packages, and some companies will use 1TIBC tons of barrels for use with filling pumps. China does not have the conditions for construction of refueling stations in the early stage. According to the mature vehicle urea promotion model in Europe, domestic refueling stations will not appear on a large scale in at least 3-5 years. "From the general introduction of Wu can understand, small packaging promotion for the current domestic vehicle urea promotion form, to meet the needs of the four diesel vehicles.

Product temperature requirements are strict with thermal storage devices

Vehicle urea is more stringent for temperature requirements and crystallizes below -11°C. This problem has aroused the attention of the majority of truck drivers. Truck drivers run around the country all year round, and extremely cold areas in the north may cause crystallization of urea, a phenomenon that plagues the trucker’s transportation schedule. Wu explained: “Small-packed urea solutions for vehicles can be stored in the room to avoid low-temperature crystallization. In automotive SCR systems, storage tanks for storing urea solutions for vehicles have a thermal insulation function, and the system is equipped with a heating device. It can prevent the product from crystallizing under low temperature environment and ensure the normal operation of the system."

Although as a vehicle urea supplier can not solve the problem of low temperature crystallization products, but some manufacturers through the addition of thermal insulation device in the urea tank to avoid the crystallization of urea solution for truck truck drivers inconvenience. In foreign countries, more tank filling equipment is used. In addition to heat preservation, it can be refilled cyclically to save on logistics and packaging costs. Sichuan Meifeng plans to sell through this method after the market matures.

In April 2013, a 600,000-ton-a-year vehicle urea solution plant independently developed and designed by Sichuan Meifeng was put into operation.

Although the road ahead is long, but vehicle urea companies have been actively exploring solutions and implementation methods, we believe that as long as the hard work, vehicle urea products can break through various obstacles, and perfectly assist the SCR after-treatment technology to eliminate the implementation of the National IV. "Stop the road."

High cost of car urea requires weighing long-term advantages and disadvantages

National IV implemented a powerful shock to the truck market. Due to the increase in costs, the National Fourth Truck increased by about RMB 30,000 to RMB 30,000, which made many consumers unwilling to accept it at the moment. The distributors in the four countries in the country were caught in the embarrassing situation of “nothing in the country to buy and the country could not sell”. In the upgrade cost of the National Fourth Truck, vehicle urea also occupies a place.

The increased cost of car urea solution to the owner is also a concern in the industry. How to look at the cost increase caused by vehicle urea, Wu said, “The annual cost of using domestic urea solution for vehicles is not too low. And the country does not currently have a special subsidy for vehicle urea, so this is for the majority of users. It is not a small cost expenditure.” According to Luo Xuefeng, deputy general manager and chief engineer of Sichuan Meifeng Fertilizer Branch, according to the impact of the product on vehicle performance and fuel consumption, “We have not conducted systematic tests on this aspect. According to the data, despite the increase in vehicle costs caused by urea solutions for vehicles, in the long term, the fuel injection of the National IV engine will be more complete, and the comprehensive fuel consumption of vehicles will be reduced. Fuel consumption will be reduced, and cost pressures will be eased or offset.”

From a macro perspective, upgrading the country's four emission standards is a major event concerning human development. The majority of diesel vehicle users need to establish a correct attitude and rationally view the issue of increasing product costs and increasing prices. The most important thing is to require car companies and supporting companies to work together to minimize the price pressure of end-users, and balance the environmental protection and the benefits of a satisfactory result for consumers.

The quality of products strictly controls the market to be perfected

According to the relevant person in charge of Sichuan Meifeng, the current domestic vehicle urea production technology threshold is not high, and it is easy to cause uneven quality of domestic vehicle urea products. With regard to the standards for car urea, foreign standards have been formulated relatively early. In the early domestic period, only two local governments in Beijing and Shenzhen have set relevant standards. The national standard for car urea in China is the diesel fuel that was just implemented on July 1, 2013. Engine Nitrogen Oxide Reductant - Aqueous Urea Solution (AUS32).

How to implement the relevant national policy standards, improve the car urea access threshold, and then improve product quality is the urgent problem to be solved in the current car urea market.

According to Wu Jiangtao, general manager of Sichuan Meifeng Jialan, “Meifengjialan is a wholly-owned subsidiary of Sichuan Meifeng Chemical Co., Ltd., while Sichuan Meifeng is a holding company of Sinopec and is currently the top ten chemical fertilizers in China. One of the production and distribution enterprises, the agricultural urea production capacity reached 1.95 million tons, and the vehicle urea solution was researched and developed since 2008, and Meifengjia Blue was finally established, so the raw material supply and cost of Meifengjia Blue in the automotive urea solution products The aspect has a natural advantage, and the cost of finished products can be achieved at the lowest domestic level."

Wu Meitao, General Manager of Sichuan Meifeng Jialan

Strictly controlling the quality of products is a very important task that requires the supervision and restriction of the relevant departments of the country. It is understood that Meifengjia Blue invests more than 600,000 construction quality inspection centers, and equipped with infrared spectrometers, density monitors to control and quality the entire vehicle urea production process, and strictly guarantee the use of Meifengjialan vehicles. Urea products can meet the relevant domestic standards. Wu Zhe also stated that the advantage of Ume Plus blue car urea solution lies in the implementation of the most advanced international standards. The production process and quality inspection standards are very strict.

The use of urea for vehicles currently on the market has yet to be further promoted. “Before the implementation of the National IV Standard, the market has already seen ways to avoid tail gas emissions without adding urea. Such behavior has been strictly prohibited in foreign countries.” Wu said "We are actively communicating with relevant environmental protection agencies and regulatory authorities and hope that this emerging market will be strictly regulated."
