Abstract�� Considering the characteristics of 2,6ditertbutylpcresol(BHT),using CY metal structure packing,revamped sieve tray towers in the 2,6ditertbutylpcresol distillation system.After revamping,the concentration 2,6ditertbutylpcresol of product995(mass fraction),the crystallization point687,The designed production was approachable.

Keywords�� ditertbutylpcresol structure packing distillation technical revamping
