    : nitrogen fertilizer, methanol industry how to transform and upgrade? From the product chain selection point of view, synthetic ammonia can co-produce natural gas, oil, hydrogen, glycol, can also produce urea ammonium nitrate solution and high-end fine chemicals; Methanol can produce polyoxyethers, olefins, aromatics and other high-end fine chemicals. At the 6th General Meeting of China Nitrogen Fertilizer Industry Association held on March 26, Gu Zongqin, Chairman of the Nitrogen Fertilizer Association and President of the Petroleum and Chemical Industry Planning Institute, proposed the key direction of nitrogen fertilizer and methanol transformation products, which attracted the attention of the participants.
    Gu Zongqin has interpreted these key directions in detail. He said that domestic natural gas supply and demand contradictions intensified, synthetic ammonia co-production of natural gas can be used as the direction of the transformation of nitrogen fertilizer industry. Nitrogen fertilizer plants using clean coal gasification technology can produce natural gas by appropriately retrofitting and expanding the scale of gasification devices and air-splitting devices, adjusting or adding transformation devices and purification devices, and side-by-side methaneization devices in ammonia synthesis processes. Synthetic ammonia transformation co-production of natural gas, with a short process, by-product steam volume of the advantages. "The core technology is methane, and we should focus on the methane process, catalyst and supporting equipment of major domestic technology developers," he stressed. As long as the price of natural gas exceeds 3.5 yuan per cubic meter, there is money to be made.
    synthetic ammonia co-production oil investment is not large, there are two main technical solutions, one is synthesizer funding synthesis, oil processing, production of diesel, gasoline, LPG, etc., Chinese science and technology synthetic oil, miner, Shanghai Yashen technology and other related technologies; Second, synthesizer gas by methanol synthesis, methanol gasoline, production of gasoline, LPG and so on, the Chinese Academy of Sciences Shanxi CoalIfication Institute, ExxonMobil, Topsoe and other relevant technologies. According to the relevant agencies forecast that the current low oil prices are only temporary, synthetic ammonia oil is still worth trying.
    for the synthetic ammonia production of hydrogen, at present, Fujian enterprises have begun to implement, the future direction of development is as a refinery, ceramic park and other supporting.
    synthetic ammonia production glycol device transformation is relatively large, the investment is very high. At present, high chemistry / Japan's Ministry of Space, Pujing - East China Science and Technology, wuhua - Huashuo - BMW, Henan coalification / structure, etc. have related technology.
    synthetic ammonia production urea ammonium nitrate solution abroad in the 1970s has developed related technology, China is still in its infancy, only Fujian Yong'an, Xinjiang Xinhua and a few other enterprises small production, there are a small number of imports each year. At present, China has 18 nitrogen fertilizer enterprises not only produce ammonium nitrate, but also produce urea, the development of urea ammonium nitrate solution has an innate advantage, can be directly linked in the process.
    methanol olefins are now a lot of domestic enterprises in doing. Last year, the consumption of methanol in the country reached 8.58 million tons, accounting for 18.3% of the total consumption of methanol. In the methanol aromatics, Hua electricity has achieved 10,000 tons / year of industrialization test success, technology from Tsinghua University.
    Gu Zongqin pointed out that in methanol co-production of high-end fine products, can pay attention to hethylamide / hetamine, styrene, α-MMA and so on.
