The one-million-ton PTA/CTA unit is one of the 16 key technological projects for China's “Eleventh Five-Year Plan†major technical equipment. The successful development of its key equipment dryer is of great significance for the realization of large-scale domestic production of PTA/CTA equipment. The maximum capacity of the two million-ton PTA/CTA plant dryers was 136 tons/hour and 138 tons/hour respectively. The specifications were 4.2 meters in diameter, 32 meters in length, 3.8 meters in diameter and 27.5 meters in length, and the weight was 390 respectively. Tonnes and 285 tons are the largest in the country.
In November 2009, two million-tonnage PTA/CTA dryers developed by Jinxi Chemicals were officially driven by Chongqing Pengwei Petrochemical. The equipment was operating smoothly at 100% full load, and the quality of the discharged materials met the requirements of the users. . Experts believe that domestic large-scale dryers fill the gaps in the domestic market, not only improving the innovation capability of China's petrochemical equipment manufacturing industry, but also reducing the purchase cost of half of dryer equipment for petrochemical enterprises and shortening the procurement cycle by half.
On June 22nd, two domestically produced million-tonne grade PTA (pure terephthalic acid)/CTA (coarse terephthalic acid)/CTA (jointly developed, designed and manufactured by CNAC Liming Jinxi Chemical Machinery (Group) Co., Ltd. and China Textile Industry Design Institute, etc.) The terephthalic acid) steam rotary dryer successfully passed the appraisal by the China National Machinery Industry Federation's first localized (set) major equipment scientific and technological achievement expert.
