  Organic Chemicals
   
 

The organic chemical industry in China began to take its shape in the middle and late 1950s, largely with the alcohol produced by fermentation of grain and the acetylene produced from raw coal via calcium carbide as the basic starting point and mainly for the development of their derivant products. It has come through the stages of the initial petrochemical industry with refinery gas and black oil as raw materials, the large-scale petrochemical industry with light oil and light diesel as raw materials and the rapid development of organic raw material industry, etc.

In the past 20 years, the development of petrochemical industry dominated by ethylene has greatly accelerated the progress of the basic organic chemicals industry in China, with a number of production plants with advanced technologies and certain economic capacities constructed and put into production, such as oxo-process butanol/octanol plants, cumin-process carbolic acid/acetone plants, o-xylene oxidation-process PA plants, ethylene-process vinyl acetate plants, high-pressure-process melamine plants and MEK plants,dimethyl ether, SEC butyl acetate plants and ethylene alcohol plants , etc., which make the organic chemicals of China reach a new level. At present, the development of organic chemical industry in China has entered a stage of structural adjustment with quality improvement, costs reduction, varieties increasing and technical renovation as the main subjects from the stage of solely meeting the market demand.
 


Starting from the 1970s, ECEC has been involved in the construction of organic chemical plants for 40 years, and has been mainly engaged in the engineering and construction of the organic chemical production plants for basic organic chemical raw materials, such as MEK, melamine, methanol, formaldehyde and citric acid, as well as for alcohol/total solvent production from grain processing, etc. ECEC has successively undertaken the engineering and construction of nearly 30 basic organic chemical plants, such as 12kt/a Melamine Plant of Henan Zhongyuan Dahua Co., Ltd., 3000t/a Melamine Plant of Iran, Wuhu Feiying 80Kt/a Formaldehyde Plant, 300kt/a Methanol Plant of Zhongyuan Gas & Chemical Industry Co., Ltd., Suzhou Anli 5000t/a ACR Resin Plant, 25kt/a MEK Plant of Fushun No.2 Petrochemical Works and 30kt/a MEK Plant of Xinjiang Tianli High and New-technology Co., Ltd., 100kt/a Dimethyl Ether Plant of Hebei Zhongjie Petrochemical Group Co., Ltd., 20kt/a SEC butyl Acetate Plant of Yueyang Huake Chemical Co., Ltd and 400kt/a MEK Plant of Shangdong Dongming Lishu Chemical Co., Ltd. etc., while the building of MEK plants in China are monopolized by ECEC.

In addition to the extensive cooperation with relevant research institutes in China, ECEC always maintains very close relationships with the licensors from western countries.

Sample projects:

12kt/a Melamine Plant, Henan Zhongyuan Dahua Co., Ltd.
End user: Henan Zhongyuan Dahua Co., Ltd.
Plant capacity: 12kt/a
Source of technology: License from Eurotechnica, Italy
Process route: The 70% urea solution produced by the urea plant is used as raw material, which is concentrated first and then reacts under high-pressure without the existence of any catalyst to produce melamine, which goes through the procedures such as pressure reduction and separation, purification, crystallization, drying, etc. to get the high-quality melamine product. The by-product ammonium carbonate/carbomate solution is recycled to the urea plant as raw material for urea production.
Year built: 1998~2000.

30kt/a MEK Plant, Xinjiang Tianli High & New-technology Co., Ltd. (on turn-key basis)
End user: Xinjiang Tianli High & New-technology Co., Ltd.
Plant capacity: 30kt/a MEK and 28kt/a MTBE
Process route: Mixed C4 is used as raw material, the isobutene in which first reacts with methanol to produce MTBE (an important gasoline additive). Then n-butene is extracted out from the mixed C4 obtained after the treatment by an extractive rectification process. The n-butene reacts with water in a hydration reaction under high pressure to produce secondary butyl alcohol. The secondary butyl alcohol is dehydrogenated to produce MEK, from the rectification of which qualified MEK product (a high-quality solvent with wide applications) is produced.
Year built: 2000-2002

100kt/a Dimethyl Ether Plant of Hebei Zhongjie Petrochemical Group Co., Ltd.

End user: Hebei Zhongjie Petrochemical Group Co., Ltd.
Plant capacity:100kt/a dimethyl ether
Source of Technology: methyl alcohol to dimethyl ether technology supplied by Dalian Institute of Chemical Physics
Process route: as feed stock, methyl alcohol is gasified under pressure and dehydrated under gas phase in the reactor to obtain dimethyl ether, qualified dimethyl ether product is obtained after rectification (a kind of aerosol spray agent, Freon refrigerant alternative, appropriate peak shving gas of urban pipeline gas , mixed gas of liquefied petroleum gas, and ideal fuel of diesel engine).
Year built: 2006-2007

20kt/a SEC Butyl Acetate Plant of Yueyang Huake Chemical Co., Ltd
End user: Yueyang Huake Chemical Co., Ltd.
Plant capacity:20kt/a SEC butyl acetate
Source of Technology: technology of butene - acetic acid for synthesis of SEC butyl acetate provided by Research Institute of Petrochemical Technology
Process route: taking mixed C4 and acetic acid as feed stocks, SEC butyl acetate is directly synthesized by means of addition reaction of n-butene in mixed C4 with glacial acetic acid under the action of acidic catalyst, qualified SEC butyl acetate(a kind of high class and widely used solvent ) is obtained after rectification
Year built: 2008-2009

40kt/a MEK Plant of Shangdong Dongming Lishu Chemical Co., Ltd.
End user: Shangdong Dongming Lishu Chemical Co., Ltd.
Plant capacity:40kt/a MEK
Process route: using mixed C4 as feed stock, n-butene is extracted out from mixed C4 obtained after the treatment by an extractive rectification process. The n-butene reacts with water in a hydration reaction under high pressure to produce secondary butyl alcohol. The secondary butyl alcohol is dehydrogenated to produce MEK, from the rectification of which qualified MEK product is produced.
Year built: 2012-2013
