On July 2, the “2010 China Melamine and Downstream Industry Development Promotion Summit†co-organized by China Chemical News and China Melamine Industry Cooperation Committee was held in Shanghai.
Beijing Yinjing Technology Co., Ltd. Tang Yin, general manager introduced the melamine production technology at the meeting, and focused on the new progress of energy-saving and capital-saving quenching melamine production technology.
According to Tang Yin introduction, the industry is accustomed to the urea production of melamine process is divided into two categories of high pressure and low pressure law. There are five kinds of original high-pressure methods that are widely used at present, and the ETEC (Allied) process is the most widely used. There are four kinds of original low-pressure methods, and the world's largest production capacity using the DSM-GPP process is 347,000 tons. In addition to mainland China, by 2009, there were 28 melamine production companies in the world and 45 units with a total capacity of 1,133,600 tons. Among them, 635,000 tons were low-pressure methods, accounting for 55.82%, and 502,600 tons were high-pressure methods, accounting for 44.18%.
At present, China's atmospheric pressure method occupies a mainstream position, the scale of the company is small, and the technology is behind, and most domestic companies lack the awareness and strength to develop new technologies. Tang Yin pointed out that the domestic average single-line design capacity is about 0.75 million tons/year, which is only 28.8% of foreign single-line production capacity; the average size of each company is 11,000 tons/year, which is only 25% of foreign companies. As a result, the melamine plant has low efficiency and poor product quality, and the overall energy consumption of the domestic industry is still in the world's downside.
Tang Yin introduced that Beijing Jingjing Technology Co., Ltd. has developed energy-saving and capital-saving gas quenching technology on the basis of its second-generation improved gas quenching technology, which reduces product investment by 50% and reduces overall energy consumption by 25%. Up to 120,000 tons / year of large scale. This technology has been recognized by the German Lurgi Company and has received extensive attention from foreign melamine giants.
