Why is the prospect of small nitrogen fertilizer difficult to predict the domestic nitrogen fertilizer companies generally have such a number of development models: First, several years since 1973, China has successively introduced 31 sets of large-scale nitrogen fertilizer production equipment from developed countries, raw material route has residual oil or stone Three kinds of brain oil, natural gas and coal are commonly known as oil heads, gas heads and coal heads. The second is the model of Shandong Hualu Hengsheng Chemical Co., Ltd. This is a local small nitrogen fertilizer company that is equipped with domestically produced large-scale nitrogen fertilizer plants. The reporter once interviewed the company in January 2005. At that time, the new unit of Hualu Hengsheng was just put into operation for one month. It is in good condition, with a capacity of 300,000 tons of synthetic ammonia and 600,000 tons of urea, and it can also produce 200,000 tons of methanol. . The third is the medium-sized nitrogenous fertilizer companies constructed by provinces, municipalities, and autonomous regions after the 1960s. The capacity of synthetic ammonia is usually between 130,000 tons and 180,000 tons. There are 53 such enterprises across the country. The fourth is the combination of several small chemical fertilizer plants of the same year to form nitrogen fertilizer enterprises with large nitrogen production capacity, such as Shandong Luxi Chemical Group and Jiangsu Linggu Chemical Group. Among them, Luxi Chemical Group acquired seven small nitrogenous fertilizer companies within a few tens of kilometers in the area of ​​Liaocheng, Shandong, through acquisitions and mergers. The annual output of urea reached 1.04 million tons, and the production of phosphate fertilizer reached 900,000 tons, which has reached a large scale. Nitrogen business performance. Fifth, the nitrogen fertilizer companies joined the Shanxi Jinmei Coal Group, which has the largest output of anthracite in China, thus ensuring the special supply of chemical coal and completely breaking through the constraints of coal. At present, five Sino-nitrogen companies, including the former Shijiazhuang Fertilizer Plant and Shandong Mingshui Dahua Group, have joined the Jinmei Group. Sixthly, the expansion of small nitrogenous fertilizer enterprises into a medium-nitrogen model will enable the production capacity of synthetic ammonia to reach an approximate size of 180,000 tons or even larger, and will form a certain degree of competitiveness, such as Henan Xinlianxin Chemical Group. The last group is currently the largest and most unpredictable group – more than 400 small nitrogen fertilizer companies with low production capacity, high energy consumption, and a single variety.
At present, the first six models of nitrogen fertilizer companies have formed their own competitive advantages. After several big heads of nitrogen have been changed to coal heads, the route of raw materials has not been a problem. As long as the supply of natural gas and coal is normal, the development of these large nitrogen and medium nitrogen will not cause serious problems. However, the situation of these 400 small nitrogen fertilizer companies is worrying.
The status quo of more than 400 small nitrogenous fertilizer companies is mainly reflected in the fact that the company survives on its own, the raw materials mainly depend on coal, and the product types are relatively single. The main products are urea and ammonium bicarbonate. Another few chemical products such as methanol are produced, which are competitive and resistant. The risk capability is not high, and even some companies’ anti-risk capability has fallen to the vicinity of the safety line. Once the prices of coal, electricity, and transportation continue to rise, they have encountered the impact of adverse weather such as droughts and floods on agriculture, or encountered safe production, With regard to environmental protection and other issues, companies are very likely to be unsustainable.
According to Liu Jincheng, president of Hebei Zhengyuan Chemical Industry Group, the total output of synthetic ammonia in the country was more than 40 million tons in 2006. According to a production capacity of 200,000 tons, 200 companies can achieve this output. He said that the market is so big that competition will be unprecedentedly fierce. Li Andong, deputy general manager of Shandong Qingdao Hengyuan Chemical Co., Ltd., also believes that China's fertilizer market is open to the outside world, and small nitrogen fertilizer companies are facing the double squeeze of domestic large and medium-sized nitrogen fertilizer companies and multinational companies, and their fierce market competition will be inevitable. In addition, the information of farmers will become more and more informed. Whoever has high quality chemical fertilizers, low prices, and good service, farmers will not buy them because they lived there for many years and they continue to surround you with their feelings. Fertilizer transfer. When this day comes, hundreds of small, competitive nitrogen fertilizer companies will have a hard time surviving.
Technological innovation is the only way out Small nitrogen fertilizer is a unique agricultural enterprise developed on the Chinese mainland. In the mid-1950s, Shanghai Chemical Research Institute and other units began designing small nitrogen fertilizer plants. In 1958, the first small nitrogen fertilizer plant in China was opened by Dalian Chemical Industry Company. When China's small nitrogenous fertilizer industry peaked, there were more than 2,000 companies. There are basically small-scale fertilizer plants in counties with grain production. However, until the mid-1980s, more than 2,000 small nitrogenous fertilizer companies produced almost all of the single ammonium bicarbonate. Although ammonium bicarbonate is a unique product of China, it also has its own advantages, such as low price and easy absorption by the soil. However, compared with the development trend of the nitrogen fertilizer industry in the world, it is still not as favourable to agriculture as urea with high nitrogen content. Urea quickly became a good fertilizer for agricultural production.
In 1986, at the time, the Ministry of Chemical Industry took the opportunity to carry out the technical reform pilot project for the conversion of ammonium carbonate to ammonium nitrate in Huixian Fertilizer Plant in Henan Province, in Shaoshan County in Shandong Province, and in Dushan Fertilizer Plant in Zoucheng County in Shandong Province and in Pingdu County in Shandong Province. In 1987, the Small Nitrogen Fertilizer Branch was established, followed by the establishment of a technical committee. From then on, the small nitrogenous fertilizer had a leader in professional technology. It can be said that the conversion of small-scale nitrogen fertilizer to ammonium bicarbonate in 20 years ago was a milestone measure.
According to Kong Xianglin, deputy director of the China Nitrogen Fertilizer Industry Association, not only ammonium bicarbonate has been changed to urea, but small nitrogen fertilizers have also undergone technological transformation in many areas and have achieved remarkable results. The first was the technical reform in 1973. The nation's synthetic ammonia capacity increased by more than 1.4 million tons, equivalent to 26.3% of the country's capacity for synthetic ammonia at that time. Since 1978, the small nitrogenous fertilizer industry has carried out technological transformation centering on energy conservation. At that time, large nitrogen plants with an annual production capacity of 300,000 tons of synthetic ammonia were introduced one after another to threaten small nitrogen enterprises in the market competition, but at the same time, they also inspired the small nitrogen fertilizer industry. One of the characteristics of imported 31 sets of large-scale nitrogen fertilizer plants is low energy consumption, and the general high energy consumption of small nitrogen fertilizers is the gap. Through this phase of technological transformation, the energy consumption of the small nitrogen fertilizer industry in the country has dropped by 35.8%, which has played an important role in changing the backwardness of small nitrogen fertilizer companies. Since 1989, small nitrogen fertilizers have undergone energy-saving technological transformations to improve the overall level of the plant, further digested and absorbed the design ideas for the introduction of large-scale ammonia plants, and further transformed small synthetic ammonia production plants based on the design philosophy of thermal energy systems engineering. In this way, the national energy consumption of small synthetic ammonia dropped by 36.9%, and the output increased by 16.1%. From the mid-1990s onwards, small nitrogen fertilizers continued to be technologically optimized with optimized processes, optimized equipment, and optimized control. At this time, the small nitrogen fertilizer process was more advanced and the equipment gradually became medium-sized. The production of small nitrogen fertilizers It has been raised to a new level.
Recently, a manager of a small nitrogen fertilizer company told reporters that because of the small size of small nitrogen fertilizers, we only have the courage to try. The technical transformation of large nitrogen and nitrogen is required to be submitted for approval. Small nitrogen fertilizers do not have these troubles. Problems are found when the problems are discovered. Technical committees everywhere support them and they do it. Many technical problems are solved in this way.
The development of small nitrogen fertilizers is a history of continuous technological innovation. There were more than 2,000 small nitrogenous fertilizer companies in the current year, and now there are only more than 400. Although there are market factors, it is an indisputable fact that people are eliminated due to their inferior skills.
Three magic weapons that cannot be ignored While focusing on technological innovation, small nitrogen fertilizer companies must not ignore the three links of fertilizer and chemical fertilizers, production of formulated fertilizers, and improvement of agrochemical services.
In the past half a century, small nitrogen fertilizer companies have gradually expanded their business scope while implementing technical reforms. They have also taken the road of fattening and improved their economic and market competitiveness. Li Fengkun, general manager of the Qingdao Alkali Tianzhu Fertilizers Branch, told reporters that he summed up three rules for the survival of small nitrogen fertilizers: First, there must be economies of scale. After several technical reforms, Tianzhu Fertilizer's ammonia production capacity has increased from 30,000 tons at the time of construction to 60,000 tons and 80,000 tons. Up to now, it has reached 180,000 tons, basically reaching the level of nitrogen. The second is to pay attention to the adjustment of product structure. To put it plainly, it is to choose the right time to start the chemical production equipment and form a complementary state of fertilizer. In 2000, Tianzhu Fertilizer launched a large-grain urea plant with a capacity of 160,000 tons. This is the second large-particle urea plant in China after Hainan Fudao Chemical Fertilizer, making Tianzhu Fertilizer's urea competitiveness greatly increased. In addition, Tianzhu Fertilizer has also been launched into a number of promising chemical products such as formaldehyde, liquid carbon dioxide, hydrogen peroxide, and glycerin while it is producing methanol. Recently, Tianzhu Fertilizer has built a set of 40,000 tons/year capacity stearic acid device. This device adopts high-pressure continuous hydrolysis, followed by evaporation, vacuum distillation, decolorization and other processes, and is currently the most advanced technology in the country. Stearic acid production equipment, raw materials using Malaysia's palm oil and the factory surplus of hydrogen can be described as two birds with one stone. The third is to pay close attention to energy conservation and consumption reduction. The China Nitrogen Fertilizer Industry Association has clear specific measures and measures.
The reporter introduced Tianzhu Fertilizer Branch's experience because the 40-year-old small nitrogenous fertilizer company has similar characteristics to more than 400 brilliance enterprises. This small nitrogenous fertilizer company, among its operating income of last year, The output value created by chemical products has accounted for half of the annual output value of the company's 340 million yuan. Other economic indicators also rank among the top in the same-scale enterprises in the country.
In 1995, the former Ministry of Chemical Industry commended 100 advanced enterprises in agrochemical services and promoted agrochemical services in the fertilizer industry. This enabled farmers to realize that scientific and rational fertilization can effectively protect the soil environment and increase unit production. Recently, the reporter learned from interviewing small nitrogen fertilizer companies such as Hebei Tianbao Chemical Co., Ltd. and Shandong Yucheng Zhongnong Runtian Chemical Co., Ltd. that they had cooperated with the local agricultural authorities for several years of soil fertilization. Matching surveys have enabled local farmers to basically understand the soil properties of cultivated land and the amount of fertilizer used, which in turn has increased local food production and farmers' income. Shandong Yucheng Zhongnong Runtian Chemical Co., Ltd. developed a fertilizer synergist that was added to urea pellets in proportion before the material processing process. After more than 170 farmers in Lucheng City and 1,313 mu of corn, the project lasted for two years. The test, the average increase of 19.2% per mu. This technology passed the appraisal of the Ministry of Agriculture in April 2001 and the product certificate of the National Agricultural Technology Extension Service Center on August 2, 2002. At the same time, this small nitrogenous fertilizer company also received the trust of the majority of farmers, and the urea produced was welcomed by farmers. Small nitrogen fertilizer is a native agricultural enterprise, has strong feelings with farmers, has a more comprehensive understanding of the local natural conditions and soil structure, door-to-door agrochemical service is an effective way for small nitrogen fertilizer enterprises to serve the majority of farmers. First, it is also a magic weapon for the survival and development of enterprises.
Small nitrogen fertilizer is a unique type of industry in China. It has been tenacious to survive and develop in China's soil and environment for half a century. The majority of farmers will not easily stay away from small nitrogen fertilizers. However, small nitrogen fertilizers do meet new challenges and are at a new developmental point. Where to go, can not but cause the industry's thinking; how to develop, but also to see their own choice of small nitrogen fertilizer.
