Overcapacity problem of acetic acid is expected to ease

From now until 2015, as an important downstream product of acetic acid, China's production capacity of vinyl acetate, acetate and PTA (pure terephthalic acid) will also expand steadily, which will help ease the current domestic excess acetic acid production capacity situation. However, the industry predicts that the overall industry recovery may be in the next two or three years, the recent overcapacity, lack of operating rate is still a problem facing the acetic acid industry. This is the news that the reporter received from the China International Acetate and Derivatives Market and Technical Conference held recently.

According to Cui Rongying, a consultant of UK Tycoon Global Chemicals, the growth of downstream demand will be to ease excess capacity and boost the main driving force of the acetic acid market. According to 2011 data, acetate, vinyl acetate, and PTA accounted for the top three levels of acetic acid consumption, accounting for 24%, 23%, and 17% respectively; in 2012, the incremental consumption of acetic acid by these three downstream products will be 290,000 tons, 70,000 tons and 130,000 tons, other downstream demand has not seen any significant changes. In the next three years, the production capacity of these three products will increase significantly.

Specifically, according to TEKYO, the production capacity of ethyl acetate will increase from about 2.5 million tons in 2012 to about 3.4 million tons in 2015. However, due to the excess capacity of ethyl acetate, the operating rate will increase. Maintained at the 50% level, therefore, ethyl acetate production may increase from 1.25 million tons in 2012 to 1.75 million tons in 2015; while sec-butyl acetate production capacity grows rapidly in the last two years, the demand for acetic acid in 2012 is expected to At 180,000 tons, it will reach 285,000 tons in 2013.

In terms of vinyl acetate, its capacity is still increasing and it is expected to increase from the current 2 million tons to nearly 3.5 million tons in 2015. Cui Rongying pointed out that the increased production capacity of vinyl acetate is mainly the production capacity of acetylene, which is distributed in Ningxia and Inner Mongolia. These production capacities mainly support the production of downstream polyvinyl alcohol, so the increase in the volume of goods is far less than the increase in actual production capacity.

PTA has achieved rapid development in China in recent years. According to Zhou Xiangjin, vice president and secretary-general of the China PTA Industry Association, China's PTA production in 2011 was 17.57 million tons, the import volume was 6.527 million tons, and the self-sufficiency rate was 73%. Under the stimulation of the demand gap, China's PTA production capacity will further expand in the next few years. “At present, the domestic PTA plant is 24.01 million tons/year, and it is expected that in 2012, it will increase production capacity by 12 million tons, which will increase acetic acid consumption by about 540,000 tons. At the same time, there are a large number of PTA plants under construction and planning. It is estimated that The actual capacity in the first half of the year exceeded 40 million tons, said Zhou Xiangjin.

“Because of the current fierce competition in the acetic acid industry, some small-scale installations will be eliminated. At the same time, the growth rate of new production capacity of acetic acid will also be reduced under such circumstances. Together, it will also help the acetic acid industry environment. Gradually get better," said Cui Rongying.
