Processes and Packings that Are Used in (Styrenemonomer/ Ethtylbenzene) Packed Distillation Columns

World war period witenessed a boom in styrene demand due to its application in the manufacture of synthetic rubber. This led to a dramatic increase in styrene capacity. Since then demand and capacity have grown continuously. There is various Technologies for Styrene monomer production. ABB-lummus/Uop, Epi Europa and Shaw stone&Webster badger Technologies are samples of them. These Technologies used of Ethylbenzene dehydrogenation method. Ethylbenzene hydroperoxidation is other Technology. Present investigation discusses first type (Ethylbenzene dehydrogenation methods). Then various packing types used in Styrene monomer/Ethylbenzene separation, is discussed. Today, more than 70% of the world capacity for styrene monomer distillation have been equipped by Mellapak structured packings. Maxpak, Sulzer BX and Intalox structured packing are in the next grades.
