Abstract

Abstract: This paper introduces the structure and working principles of dryer in PTA plant. It analyses the causes for the failure such as material deposit, dew point corrosion and deformation of steam inlet and hydrophobic 'R' pipe during drying process. Meanwhile, combining with process conditions, the paper expounds the parameter adjustment and equipment structure characteristics and presents specific solutions. This ensures the long-term stable operation of the dryers and provides useful experience for the overhaul of dryers in similar units.

Key words: PTA, dryer, material deposit, corrosion, distortion, countermeasures
