Of these intellectual achievements, new product development is a major highlight. Chlorination titanium dioxide production technology is the world's advanced titanium dioxide production technology, with a high degree of automation, large scale, less waste, high product quality and special advantages, but for a long time, China has only a few small and medium-scale production of titanium dioxide plant, Single species, low product quality, and serious pollution, some of the high-grade titanium dioxide produced by chlorination are all dependent on imports. To this end, Jinzhou Titanium Dioxide Factory invited foreign experts to conduct technical diagnostics for the 15,000-ton chlorination project that was completed in 1996 but has not been put into operation. The diagnosis of foreign experts pointed out that the current process equipment is suitable, and it is not inferior to other foreign equipment. As long as it breaks through technical barriers, it can fully satisfy production. According to the opinions of experts on local adjustment of equipment, Jinzhou Titanium Dioxide Factory also cooperated with the former CAS Institute of Chemical Industry and Technology, and developed a new type of oxidation furnace using the patented technology of the Institute. After five years of hard work, the entire process has been opened to realize batch production. produce. The breakthrough of this project not only broke the situation in which all of China’s high-grade titanium dioxide relied on imports, but it also ended the history of chlorinated titanium dioxide in China.
The results of some major device transformations have also attracted attention. Henan Zhongyuan Dahua Group Co., Ltd. has an annual production capacity of 300,000 tons of synthetic ammonia and 520,000 tons of urea. However, during the production process, they found that the methane content at the outlet of the secondary reformer in this unit was high. The original design was 0.9%. Actually, it was 1.3% or even as high as 1.7%. This not only affects the operating system load but also becomes a system. Hidden dangers of safe and stable operation. In addition, the design of the urea stripping process of the unit is 65%, which is actually only 57%. The carbon dioxide conversion rate of the urea synthesis tower is low, which causes problems such as increased load on subsequent recovery systems, increased steam consumption, and high ammonia consumption. Although the company's technical staff also conducted technical research, but because some of the technical parameters require high precision and difficulty, the effect is not ideal. To this end, the Group has hired experts from Germany, Italy and Canada to provide technical guidance. After the experts arrived at the company, they proposed to transform the air distributor of the second stage furnace and use the space of the lower part of the urea synthesis tower 16 meters, an increase of 7 blocks. In the high-efficiency tray, the original 10 trays were changed to high-efficiency trays. After the implementation of the plan, not only the methane content at the outlet of the secondary oven reached the design value, but also the carbon dioxide conversion rate of the urea plant was increased. 58% increase to 62%~63%. Calculated by increasing the carbon dioxide conversion rate by 4%, the net saving of medium-pressure steam is about 6 tons/hour, and the subsequent recovery system's load and ammonia loss are reduced, and a long-term problem has been solved. technical challenge. After the above transformation and solution to the bottleneck of synthetic ammonia plants, the production capacity of urea after technological transformation has increased from 520,000 tons/year to 580 tons/year, with an annual new production value of 72 million yuan and a profit of 2348 million yuan.
In the interview, the reporter learned that these participating projects are representative projects for the introduction of intellectual achievements, and they are selected from a large number of intellectual achievements. The actual number is more than the number of exhibitors. Take Liaoning Province as an example. Although there were only a few hundred achievements in Liaoning's participation in the show, during the "Tenth Five-Year Plan" period, they had introduced as many as 1,688 petrochemical, metallurgical and mechanical intelligence projects, including even the national "863" key projects.
China's petrochemical industry has achieved fruitful intelligence
The 2006 China International Talent Exchange Conference and High-tech Exhibition was held in Shenyang recently. The exhibition focused on high-tech exchanges of international talent attracted at the same time nearly 700 institutions, 84 expert organizations, and more than 20 provinces, autonomous regions, and municipalities in more than 30 countries, including Russia, the United States, Canada, and Australia. At the exhibition, more than 1,500 intellectual innovation achievements were exhibited, including more than 300 petrochemical achievements.
