Exampled with the dryer used in home produced PTA plantant with the capacity of one million ton annually, the working principle and drying mechanism of rotary steam tube dryer was studied, and the design of PTA dryer, calibrated parameters and practi-cal experiment data were comprehensively analyzed. Based on these works, the process design method for rotary steam tube dryer was summarized, and the methods for calculating the key parameters, such as resident time and total heat transfer coefficient, were presen-ted. The design result had been applied in the engineering practice of the sample project.
