China's first million-ton PTA dryer was successfully developed

China's first million-ton PTA dryer was successfully developed in Jinxi Chemical Machinery Group, ending the long-term dependence on imports of key petrochemical equipment in China and filling the gap in major domestic equipment manufacturing.

The one million-ton PTA dryer is one of the key research projects of China's “Eleventh Five-Year Plan”. PTA is a raw material for the production of polyester film, fiber and packaging resin, while polyester fiber and packaging resin are important raw materials for the apparel, food and beverage packaging industries. In recent years, domestic PTA production has been unable to keep up with market demand. The million-ton PTA dryer is an important device for large-scale production of PTA. In the past, it relied on foreign imports, and the price of each set of equipment was as high as 100 million yuan. At present, the price of this dryer independently developed by China is only half of that of imported equipment, and the production and delivery time can be shortened by half compared with similar foreign companies.
