Acetic Acid Industry: The Production Of Acetic Acid Has Become The Trend Of Methanol - Acetic Acid,

As domestic Methanol France continued new installations and expansion

, 2010 Methanol production capacity will reach 3.2 million tons / year, as operating rates by 90% of the total, the output will reach 2.88 million tons.

Investment adviser in Chemical industry Industry researchers often Yi Chi pointed out that industrial production in the four production Acetic acid Technologies and methods, they are: alcohol laws, ethylene, low-pressure methanol method, UOP / Chiyoda. In China, with the UOP / Chiyoda production of the device has not yet put into production, the production of acetic acid process routes are mainly alcohol law, ethylene and methanol method.

Alcohol law which is the earliest use of acetic acid production process, for production in 1953, after several decades of domestic enterprises through production practices and technology, in energy saving, waste management, etc. have made a big down improve the current virtually all domestic small devices produced using this method. However, due to manufacture one tonne of acetic acid required for each of about 0.9 tons of ethanol consumption, while the market production of ethanol from the fermentation of grain prices reached 5,000 yuan / ton, the production of acetic acid with ethanol profit margins smaller, has now been phased out.

Production process using ethylene vinyl acetate mainly as raw material, each ton of ethylene acetate consumes a large amount of about 0.5 tons, while the market price of ethylene basically 9,000 yuan / ton, making use of ethylene the cost price of acetic acid production reached 5,000 yuan / ton. If prices fall, acetic acid, then the business is essentially no room for profit.

The method used to produce methanol, then have a certain advantage. Methanol carbonylation synthesis technology is more advanced, this approach to coal as raw material, and the present of methanol has a lot of excess capacity in the state, raw material costs will not be high, but yields are relatively higher.

Chang Yi Chi that using alcohol to produce acetic acid method and the cost of vinyl acetate with the market price is basically little difference, can not get larger profits with the UOP / Chiyoda cost of production of acetic acid is relatively low, But now my device when not in operation, the scale of construction is also very small. Therefore, since low-cost reasons, the production of acetic acid with methanol, acetic acid has become a trend in the development of enterprises.

In addition, China also has low-pressure Methanol process completely independent intellectual property rights, to build a relatively large scale of production facilities, coupled with the current international Oil And food shortages, low-voltage devices methanol method obvious advantages. The ethylene plant as acetic acid and alcohol laws and the high cost of small issues, will face the risk of shutting down or changing products.

Investment adviser published in "China's acetic acid industry 2010-2015 Investment Analysis and Prediction of the report" shows that since the 90s of the 20th century, Shanghai Wujing Chemical, Sichuan to introduce the Yangtze Acetyl Chemicals BP technology the construction of a Low Pressure Methanol Synthesis of acetic acid plant in Jiangsu SOPO (600,746, stock it) Group uses the technology developed internally developed a set of low-pressure methanol synthesis of acetic acid plant. Currently Methanol Acetic Acid, 5 sets of law has been put into operation, under construction device 4-5 sets of fewer than 10 sets of the proposed device. Law in 2005, low pressure methanol acetic acid production capacity and output of total capacity and output account for more than 60%.
