China's key casting large drying equipment "China Core"

"National Drying Technology and Equipment Engineering Technology Research Center" is based on Tianhua Chemical Machinery and Automation Research and Design Institute. Since it was formally approved by the Ministry of Science and Technology in November last year, the task of engineering technology development has been fully carried out. Relying on the large-scale drying technology and equipment localization research and development achieved gratifying results: the steel industry coke oven coal moisture control device and the petrochemical industry million tons grade PTA (pure terephthalic acid) drying technology and equipment to achieve the current international advanced technology of the same kind Level.

After the successful use of the PTA dryer developed by the National Drying Technology Center at the 325,000 tpa/year PTA plant of Luoyang branch of Sinopec (600028), they continued to explore CTA/PTA (coarse terephthalic acid/pure terephthalic acid). Drying theory and industrial tests verify and perfect the CTA/PTA drying mathematical model and master the key technology of CTA/PTA drying process and equipment design. In 2007, they took delivery of the 600,000-ton/year PTA CTA/PTA dryer of Jialong Chemical Fiber Corporation.

In February 2008, the center also contracted a Sinopec (600028) Yizheng chemical fiber 1 million tons/year PTA project CTA/PTA dryer development contract. Yizheng Chemical Fiber's 1 million tons/year PTA project adopts the process technology of China's independent intellectual property rights, and the supporting CTA/PTA dryer is also the largest steam tube rotary dryer independently developed by China. The dryer will be delivered in March 2009. installation.
