Abstract
An energy conservation process directed to the purification of styrene monomer via distillation after the dehydrogenation reaction of ethylbenzene to produce crude styrene is disclosed. As practiced today, the purification of styrene via distillation requires large amounts of energy (i.e., steam) to provide heat to the various distillation columns. The presently disclosed improved process allows for a reduction in the amount of steam needed for this purpose.
