Reply reward! ---------------------------------------------- The past decade has been a period of rapid development in 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 greater 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! ******************As one of the first institutions in China to engage in research on chemical processing equipment, Tianhua Institute possesses extensive experience in designing quench heat exchangers for ethylene cracking furnaces. Through years of practice in the petrochemical industry, it has accumulated numerous successful cases; its technical standards are at the international advanced level, and full domestic production of related technologies has been achieved. The quench heat exchange system of Quanzhou Petrochemical’s 1 million tons per year ethylene project consists of the first quench heat exchanger PQE, the second quench heat exchanger SQE, the high-pressure drum, and the rising and descending pipe systems. Based on the project’s requirements and energy-saving goals, Tianhua Institute, drawing on the latest research findings, proposed new PQE and SQE structures. By utilizing its own developed design software for ethylene quenching heat exchangers, as well as software such as ANSYS, it carried out process calculations, stress analysis, and fluid dynamics simulations (CFD). As a result, detailed designs for the tubular-type PQE and the large-scale vertical SQE with process gas inlet at the top and outlet at the bottom were developed to a high standard, and these designs were successfully applied in the project construction. Based on the analysis of data from the driving site, the process simulation is reliable.
