2005年世界精对苯二甲酸(PTA)产能为3 343万t,产量为3 179万t;2013年产能增至8 590万t,产量也增至6 872万t;2005~2013年世界PTA产能和产量年均增长率分别为7.45%和6.64%。2005~2013年世界PTA产能增长情况见表1。从表1可以看到,近8年来,世界PTA产能增速很快,这其中又以亚洲为主导,亚洲又以中国为导向,截至2013年底,国内PTA总产能达到3 530万t,亚洲产能达到6 000万t以上,中国的PTA产能占据亚洲产能的59%,世界产能的41%。中国在PTA界的“大佬”地位不可撼动。未来几年,
The world production of refined terephthalic acid (PTA) in 2005 was 343.4 million tons with a production volume of 31.97 million tons; its production capacity increased to 89.9 million tons in 2013 and its output also increased to 68.72 million tons; from 2005 to 2013, the world’s PTA The average annual growth rate of production capacity and output were 7.45% and 6.64% respectively. The growth of world PTA capacity in 2005 ~ 2013 is shown in Table 1. As can be seen from Table 1, in the past eight years, the world PTA production capacity growth rate is very fast, which again led by Asia, Asia and China-oriented, as of the end of 2013, the domestic PTA total production capacity reached 35.3 million t, Asia production capacity Reaching over 60 million tons. China’s PTA capacity occupies 59% of the production capacity in Asia and 41% of the world’s production capacity. China’s PTA community “big brother ” status can not be shaken. The next few years,
