According to the national industrial policy, the needs of regional economic development and the allocation of its own technical force, the company adheres to Scientific Outlook on Development and has made outstanding achievements in the process of independent innovation and taking the road of new industrialization. The company has studied and demonstrated many times and formulated a series of practical scientific and technological innovation development plans. In just a few years, in the scientific and technological innovation activities, * * * has implemented more than ten R&D projects, such as autonomous region scientific and technological projects, torch plan projects and national tenth five-year plan scientific and technological key projects, and completed a number of high-tech equipment test and development research projects, which has continuously exerted the company's production capacity and effectively promoted the industrialization process. From 200/kloc-0 to 2008, a total of scientific research funds were invested.
Based on the strategic development direction of three-dimensional development and comprehensive utilization of Lop Nur Salt Lake, the company took the key project of the 11th Five-Year National Science and Technology Support Plan "Research on Key Technologies of Comprehensive Development and Utilization of Lop Nur Salt Lake Resources" as an opportunity, and took a "two-pronged, hand in hand" approach to carry out a number of project demonstrations and experiments in view of the urgent problems of comprehensive utilization and high-value development of raw material resources in the development of Lop Nur Salt Lake resources. On this basis, accelerate the industrial test project of potassium sulfate magnesium fertilizer, strive for a breakthrough in technology and economy (product cost performance) in a short time, and lay the foundation for building Lop Nur Salt Lake into the largest potassium sulfate production base and comprehensive utilization industrialization base in China.
Third, the project construction
1 20,000-ton industrial pilot plant
In September 2002, the company began to build a 20,000-ton/year industrial pilot plant project, which was put into trial operation in July 2003 and reached production in June 2003 at 5438+ 10. The successful development of this project indicates that Luobo potash fertilizer "Lop Nur brand potassium sulfate product" has begun to enter the global potash market.
2, 2 expansion 3 technical transformation project
From June 5438, 2003 to February, 2003, in order to tap the potential of existing devices and improve the existing technology, the company plans to build a 2- expansion -3 technical transformation project.
A newly developed mixed decomposition crystallizer was adopted in the transformation, which improved the product granularity and reduced the chlorine content. At the same time, it provides the basis and parameters for the design of crystallizer in 6.5438+200,000 tons project. After the technical transformation is completed, the production cost of the product is obviously reduced.
3, 4 and 8 technical transformation projects
The project started in September 2004 and the transformation has been completed. After the completion of the project, the pilot plant has reached the production scale of 654.38+10,000 tons/year.
The pilot plant of 20,000 tons/year potassium sulfate industry is an important project approved by the State Economic and Trade Commission and the Economic and Trade Commission of the Autonomous Region and included in the national technological innovation project and the key project plan of the autonomous region in 2002. It is also an important project in the investment plan of the 6,543,8+200,000 tons/year potash fertilizer project in Lop Nur base. The construction of industrial pilot plant is of great significance for obtaining a complete set of design basis and parameters for the construction of 6.5438+200,000 tons/year potassium sulfate project, simulating the whole process of production, marketing and management, and cultivating the company's production, sales and management teams.
465,438+200,000 tons of potash fertilizer project
On April 25th, 2006, the project of potassium sulfate with an annual output of 6.5438+200,000 tons was officially started in Lop Nur, Xinjiang. It consists of seven main projects, including brine mining and transportation, salt field mining and transportation, processing plant, external water supply, thermal power station, Hami railway special line and storage, and other supporting projects, such as Hami office base and Hongliujing secondary water supply project. With a total investment of 4.8 billion yuan, this project is listed as one of the key construction projects in the 11th Five-Year Plan and the newly started 12 key projects in the western region in 2006. After more than two years of construction, the project has produced excellent potassium sulfate products in 2008. Together with the previous industrial test device of 6,543,800 tons, the annual production capacity is 6,543,800 tons. The second phase of the project will increase the potash fertilizer production capacity by 6.5438+0.7 million tons/year, and it is planned to form an overall potash fertilizer production capacity of 3 million tons/year around 2065.438+02.
After the 65.438+0.2 million tons of potassium sulfate project is completed and put into operation, the annual output value of the company will exceed 3 billion yuan, the profit will exceed 65.438+0.3 billion yuan, and more than 65.438+0.500 people can be directly employed. After the completion of the project, it will play an important role in implementing the strategy of transforming superior resources in the autonomous region, promoting the process of new industrialization, promoting the economic development of Xinjiang and stabilizing the frontier; It is of positive significance to serve "agriculture, countryside and farmers", adjust the structure of agricultural products, promote the development of China's agriculture to high value, and implement the important task of the central government to build a new socialist countryside; It plays an important role in alleviating the contradiction between supply and demand of potash fertilizer in China, improving the self-sufficiency rate of potash fertilizer in China and reducing the risk of international trade.
