With the continued rapid growth of our country’s economy, domestic The demand for polyurethane has reached more than 15%. The main raw materials of polyurethane, MDI, TDI, and polyether, are in huge demand. The price has also risen with the increase in international oil prices. This huge business opportunity has promoted the global polyurethane market. The new round of investment boom by raw material manufacturers in China has also accelerated the speed of domestic enterprises to build and expand large-scale raw material projects.
1. ;font-weight:bold;font-size:19px”>Production situation of isocyanate in China
China Apparent consumption of MDI in 2003 The production volume is 320,000 tons, of which 100,000 tons are produced by domestic devices and 220,000 tons are imported. The apparent consumption in 2004 was 436,000 tons, including 153,000 tons of pure MDI and 283,000 tons of polymerized MDI, with a growth rate of 36.3%. In 2005, the apparent consumption of MDI was approximately 510,000 tons, including 180,000 tons of pure MDI and 330,000 tons of polymerized MDI, with a growth rate of 17%. In 2006, the apparent consumption was approximately 630,000 tons, an increase of 22%, of which 129,000 tons of imported pure MDI, 285,000 tons of polymerized MDI, and 267,000 tons of domestic production (including the total output of Yantai Wanhua, Ningbo Wanhua and Shanghai Lianheng) were , exporting about 50,000 tons. It is estimated that my country’s MDI demand will reach 1.2 million tons in 2010, with an average annual growth rate of nearly 20% from 2005 to 2010.
my countryThe current annual production capacity of MDI is 1.14 million tons, and the production capacity will reach 2.45 million tons by 2012; the current annual production capacity of TDI is 350,000 tons, and the production capacity will reach 1.05 million tons by 2012. By then, my country will have the largest MDI and TDI production capacity in the world蕞One of the largest countries. Special mention needs to be made of Yantai Wanhua Polyurethane Co., Ltd. and Ningbo Wanhua Polyurethane Co., Ltd., whose annual MDI production capacity will exceed 1 million tons by 2012, which will undoubtedly improve the core international competitiveness of my country’s PU industry and ensure Its stable development will play a decisive role.
my countryIn 2003, TDI output was 44,000 tons, imports were 256,000 tons, and apparent consumption was 300,000 tons. The apparent consumption in 2004 was 328,000 tons, with a growth rate of approximately 9%. Apparent consumption was 345,000 tons in 2005 and 373,000 tons in 2006. Due to the irrational surge in domestic TDI prices from 2004 to 2006, the operating rate of the soft foam industry was very low, resulting in slower growth in domestic TDI consumption.
Aiming at my country’s isocyanate Due to the huge demand and supply gap, major international isocyanate companies and Chinese companies are building and expanding isocyanate production plants. Yantai Wanhua has an MDI production capacity of 200,000 tons/year at its headquarters in Yantai. The MDI integration project in Yantai Bajiao Port New Industrial Zone started in March 2011, and the first phase plans to add 600,000 tons/year. MDI, in addition to building 300,000 tons of TDI, will reach capacity in 2014; Wanhua Ningbo MDI plant was put into operation in March 2006, and was expanded to 300,000 tons in 2008. In 2010, another 300,000 tons of MDI plant was built. An additional 600,000 tons/year of MDI production capacity will be added, and Wanhua’s total MDI production capacity in Yantai and Ningbo will reach 1.8 million tons/year. In Caojing, Shanghai, Shanghai Lianheng Isocyanate Co., Ltd., a joint venture established by BASF, Huntsman and my country’s Huayi Group, has been put into production. 240,000 tons/year MDI and 160,000 tons/year TDI. Gansu Juyin Company successfully developed its own TDI technology in 2005, and its TDI output reached 50,000 tons/year by the end of 2006. Jinzhou and Shandong each built new 50,000 tons/year TDI devices. Liaoning Northern Jinhua Polyurethane Co., Ltd. has started a TDI production project since 2007. The first phase of the 50,000 tons/year production device has been completed and put into operation. The second phase of the 100,000 tons/year production device started construction in 2011. In addition, the MDI project is also Brewing. The 100,000 tons/year TDI project of Fujian Petrochemical Group’s Southeast Electrochemical Relocation Project is under design and is expected to be completed in 2013. Bayer’s wholly-owned 350,000 tons/year MDI plant in Caojing, Shanghai was completed in October 2008. It plans to expand to 500,000 tons/year. It will also build a new 500,000 tons/year MDI plant to continue to expand its MDI production capacity in Shanghai. Expanded to 1 million tons/year, its Shanghai 250,000 tons/year TDI device has recently been completed and put into operation. In addition, the production capacity of Bayer’s Shanghai HDI factory will be expanded from 30,000 tons/year to 80,000 tons/year, and a 30,000 tons/year IPDI device will be built. BASF’s 400,000 tons/year MDI project in Chongqing was approved in 2010 and is expected to be completed in 2014. my country’s isocyanate production capacity in the past ten years is shown in Table 1-12. my countryisocyanates will be self-sufficient and have a surplus. .
my country’s Ministry of Industry and Information Technology issued the “Isocyanate (MDI/TDI) Industry Access Conditions” on December 10, 2009, requiring the starting size of a single set of new MDI devicesMustreach300,000 tons/year and above. The starting size of a single set of new TDI equipmentmustreach150,000 tons/year and above, except for renovation or expansion projects. This facilitates resource integration.
2. my country Production status of polyether polyols
Domestic polyether polyol production was 450,000 tons in 2003, 640,000 tons in 2004, 750,000 tons in 2005, and approximately 850,000 tons. The corresponding demand was 785,000 tons in 2004, 889,000 tons in 2005, and about 1 million tons in 2006. In 2009, the polyether production capacity was 1.6 million tons, and the production capacity reached 1.03 million tons.
Our country is currently gathering There are more than 30 ether polyol production companies, and more than 10 companies have 10,000-ton production equipment. Most of them are equipment and technologies introduced from Japan, Italy, etc. in the 1980s. By 2003, the production capacity of my country’s major polyether polyol factories reached 780,000 tons. In 2005, with the expansion of Gaoqiao Petrochemical Plant No. 3 to 200,000 tons/year, the Guangdong Huizhou plant jointly built by CNOOC and Shell reached 135,000 tons/year. / year device, my country’s polyether polyol production capacity has reached more than 1.2 million tons / year in 2006, with an output of approximately 800,000 tons and a consumption of approximately 986,000 tons. By 2011, polyether polyol production capacity is estimated to reach 2.6 million tons/year, while domestic market consumption will reach 1.5 million tons. The newly built polyether polyol plants in recent years include the 150,000 tons/year plant built by Qingdao Xinyutian in Guangdong, and the 100,000 tons/year plant of Nanjing Gimpo Kumho Chemical Co., Ltd. jointly built by Jiangsu Zhongshan Chemical Co., Ltd. and South Korea’s Kumho. , Bayer is building a 250,000 tons/year device in Shanghai, Suzhou Sinochem International Polyurethane Co., Ltd. (100,000 tons), and Shandong Blue Star Dongda Chemical Co., Ltd. (100,000 tons).
