On September 20th, the world’s largest CTA/PTA steam rotary dryer with an annual capacity of 4 million tons was successfully shipped to Nanjing and will be ready for delivery. The large-scale drying unit from research and development, design to manufacturing, all by China Chemical Tianhua Chemical Machinery and Automation Research and Design Institute independently completed, to fill the gaps in key equipment in the field of domestic large-scale devices to the world advanced level, the petrochemical industry to dry equipment Purchasing costs are reduced by 50%.

According to Xiao Shimeng, dean of Tianhua University, in the past, only a few developed countries were able to produce large-scale dryers, which was not only expensive, but also had problems such as short service life, poor steam condensate discharge, and so on. After the localization of large-scale dryers, the cost of industrial production has been greatly reduced. This set of independent production by Tianhuayuan consists of two large drying units with a diameter of 4.2 meters, two diameters of 4.5 meters, and a diameter of 4.8 meters. It has a large processing capacity, good sealing performance, high thermal efficiency, stable and reliable operation, and long service life. With such excellent performance as long products, the products not only radiate the domestic market, but also go to the world and are exported to countries such as Belgium, the United States, and Spain. As of August this year, the large-scale drying units produced by China Chemical Tianhua Institute have achieved a total output value of 1 billion yuan, saving the country 100 million U.S. dollars in foreign exchange.
It is understood that the drying process accounts for 20% to 25% of the total energy consumption of the process industry. The development and application of advanced, high-efficiency, energy-saving drying processes and equipment is of great significance to the process industry.
