HIGH INTRINSIC VISCOSITY COLUMN REACTOR FOR POLYETHYLENE TEREPHTHALATE |
摘要 |
Disclosed are counter-current reaction columns with improved pressure drop and temperature profiling. Such improvements result in a higher IV prepolymer. The improvements over prior art designs include reducing the length to diameter ratio of the cylindrical section of the column while maintaining the same active volume, and / or including an external heat exchanger. Further, inert gas flowrate and prepolymer residence time is increased. |
