Abstract:
The present invention relates to an apparatus and a method for preparing bisphenol A, and provides an apparatus and a method for preparing bisphenol A that can increase the energy efficiency of the entire process by utilizing an internal heat source.

Claim (Index 1):
An apparatus for preparing bisphenol A comprising:\n a first crystallizer to which a bisphenol A concentration stream containing a reaction product that phenol and acetone are reacted is introduced to crystallize bisphenol A and to discharge an adduct of crystallized bisphenol A and phenol; a first solid-liquid separator in which the adduct of crystallized bisphenol A and phenol in said first crystallizer is introduced thereto, and separated from a mother liquid and discharged; a phenol introduction port in which a phenol stream is introduced into the adduct of crystallized bisphenol A and phenol discharged from said first solid-liquid separator to discharge the mixed stream of phenol with said adduct of crystallized bisphenol A and phenol; a first heat exchanger in which said phenol stream is heated before said phenol stream is introduced; a second heat exchanger in which the adduct of crystallized bisphenol A and phenol in the mixed stream flowing out to said phenol introduction port is melted to discharge the molten stream; and a second crystallizer to which the molten stream discharged from said second heat exchanger is introduced to recrystallize bisphenol A and to discharge the adduct of crystallized bisphenol A and phenol.
