Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! The 100,000-ton-per-year PC secondary fluidized-bed + ridge-tower type tertiary continuous circulation drying system designed by Tianhua Yuan for Cangzhou Dahua New Materials Company has been successfully built and put into operation, marking the successful domestic implementation of a high-capacity drying process for flake-type polycarbonate (PC) in China. This is a successful example of Tianhua Academy’s willingness to innovate in new fields, its readiness to take on challenges, and its ability to deliver results. Tianhua Institute has a **Research Center for Drying Technology and Equipment Engineering.** The Drying Equipment Research Institute under it has been dedicated to research in drying technology and equipment for a long time, and possesses comprehensive capabilities including process design, as well as the research, development, design, manufacturing, and installation of equipment. The main drying equipment developed includes large steam-tube rotary dryers, paddle dryers, disk dryers, fluidized bed dryers, ridge dryers, flash dryers, and air-flow tube dryers. The main materials used are polypropylene, PTA, CTA, PC, sludge, catalysts, and coal powder, among others. It possesses extensive engineering and design experience, as well as manufacturing capabilities in the development and application of new drying processes and drying equipment. Tianhua Institute has established good cooperative relationships with well-known domestic polycarbonate (PC) manufacturers, and has accumulated a great deal of technical expertise in the field of polycarbonates. Tianhua Institute is responsible for the design of the continuous cyclic drying process, as well as the key equipment and control systems; this continuous cyclic drying process helps reduce the system’s energy consumption and equipment investment ； Key process equipment manufactured by Tianhua Institute, such as fluidized bed reactors and ridge towers, not only improve the quality and reliability of the equipment for customers but also help save significant amounts in equipment investment, thereby accelerating the progress of project construction. The successful implementation of this project achieved a new breakthrough in the field of large-scale flocculent polycarbonate (PC) drying process systems at Tianhua Institute, and also provided valuable experience for the design of other large-scale drying processes and equipment for new materials in the future.
