The principium and the mechanism of drying process of rotating steam tube dryer in pure terephthalic acid (PTA) industry were studied by taking example of a domestic-based sample project with production capacity of 1 million t/a PTA. Based on the analysis of the design and operating data of exiting industrial PTA plants, an approach to optimizing the key design parameters of the dryer, such as diameter, length, overall heat transfer coefficient (OHTC), resident time, was proposed and a systemic method of process design of PTA dryer was established. The result of the design was optimized and demonstrated by the experiment, and will be applied in the sample projects.
