The vast market to be upgraded Methionine, also known as methionine, is an important amino acid species. In 2007, China imported more than 91,200 tons of methionine in various specifications, accounting for 51% of the total imports of amino acids. The import amount reached US$207 million, accounting for 47.5% of the total imports of amino acids. Domestic methionine products, nearly 84% for the feed industry, 12% for the pharmaceutical industry, 4% for the spice industry. According to the feed additive industry development plan, by 2010 China's mixed feed production capacity will reach about 150 million tons / year, only this one needs 70,000 tons / year of methionine supply.
In recent years, despite the rapid development of the methionine industry in China, the annual production capacity is still less than 10,000 tons. There are only five or six production companies, and no one is above 10,000 tons. There are generally small scale, low output, and backward technologies. The problem of single species, high-end products is almost blank. With the rapid development of chemical industry, pharmaceutical industry and feed industry, and the continuous expansion of new uses of methionine, the downstream industry has constantly put forward new requirements for the chemical and physical properties of methionine.
In January 2006, the China Blue Star Group Corporation completed the settlement of the French company Adisseo with a purchase price of 400 million euros. The company is the second largest methionine producer in the world and the only company in the world that can produce both solid and liquid methionine products. It is reported that Bluestar will use this acquisition to reform the domestic methionine project, introduce a new device for liquid methionine technology, and form a production capacity of 150,000 tons per year in China. Industry experts believe that this move will effectively promote the upgrading of China's methionine industry.
It is imminent to strengthen technological innovation Methionine production uses chemical synthesis, and Evonik is the only company that can produce three major amino acid products at the same time. At present, the preparation process is backward and the equipment technology is obsolete, which has become a key factor affecting the development of the methionine industry in China. How to intensify scientific and technological research and reduce the gap with developed countries as soon as possible is an important issue facing companies and scientific researchers in the industry.
Our country began to study the chemical synthesis of methionine technology since the 1950s and succeeded. In 1959, the first production unit for synthetic methionine was built. At present, the national production capacity of methionine is about 1,000 tons, and the annual output is about 700 tons. The methionine produced is mainly used in medicine. Due to the lack of advanced and mature technologies, domestic production of methionine for feed has not been realized so far.
The main raw materials for the production of methionine are propylene, hydrogen sulfide, and hydrogen cyanide, a 30,000-tonne/year methionine device, approximately 13,500 tons of propylene per year, 36,600 tons of sodium cyanide, and 9,400 tons of sulfur per year. hydrogen. China's existing propylene production capacity is 1.5 million to 1.6 million tons/year, and sodium cyanide is 90,000 tons/year or more. Hydrogen sulfide production is also very large. It can be said that China's large-scale petrochemical enterprises basically all have raw material resources, and the conditions for the large-scale development of the methionine industry are maturing.
Experts pointed out that although China has been able to produce superior grade methionine, the overall preparation process and equipment technology are lagging behind; some high-quality, high value-added products still need a lot of imports, and there is a big gap between product competitiveness and foreign companies. In addition, environmental pollution and safety production issues are also important factors that restrict the development of the industry. From the perspective of technological innovation, in addition to focusing on solving these problems, the prospects for nano-sized methionine are promising, and should also serve as the main direction for the upgrading of domestic methionine products.
Three-pronged approach to promote sustainable development Experts believe that the general idea of ​​the development of China's methionine industry should be to establish a safe, clean, efficient, sustainable development of the security system, to achieve a high degree of industry concentration, give full play to the scale of competitive advantage. Specific practices include the following three points:
The first is to accelerate the scale. Methionine production enterprises should form a scale advantage as soon as possible, according to the characteristics of resources and market distribution and the degree of industrial linkages, take the strong combination of strengths, mergers, shares, etc., to form cross-regional, cross-ownership, cross-industry, or even multinational operations for the integration of large-scale production and sales Or large group companies to optimize resource allocation, increase industrial concentration, and enhance competitiveness in the international market. The success of Bluestar Group's head office in the acquisition of the French company Antis Group is a good example.
Second, we must accelerate the pace of technological transformation of enterprises and promote industrial upgrading. Methionine production enterprises must actively adopt new technologies, new processes, and new methods to reduce raw material consumption, develop and produce new products with high added value, strengthen joint research and development among enterprises, form scientific and technological achievements, promote industrial upgrading, and improve product quality. , grades and added value to improve the competitiveness of China's methionine industry in domestic and foreign markets.
Third, we must strengthen ecological construction and environmental protection and implement clean production. It is necessary to further improve corporate social responsibility, vigorously develop and promote methionine clean production technology, strengthen ecological construction and environmental protection; corporate technological transformation efforts toward the closed loop system should also be a strategic choice for the sustainable development of China's methionine industry.
Methionine Industry Achieves Leapfrogging Development
In recent years, the domestic methionine market is in good shape and prices have been rising. As the price of raw materials increases and downstream demand increases, there is still room for further rise in methionine prices. According to the forecast of experts, the annual demand for methionine in the world in the next 10 years is expected to increase to 1.1 million tons, which is double that in 2007, and the demand in the domestic market will also grow rapidly. For China's methionine industry with obvious raw material advantages, it is now facing a rare opportunity for development.
