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 12):
A method for preparing bisphenol A comprising steps of:\n crystallizing bisphenol A through a first crystallizer in a bisphenol A concentration stream comprising a reaction product that phenol and acetone are reacted and discharging the adduct of crystallized bisphenol A and phenol; separating the adduct of crystallized bisphenol A and phenol in said first crystallizer from the mother liquor through a first solid-liquid separator and discharging it; introducing a phenol stream into the adduct of crystallized bisphenol A and phenol discharged from said first solid-liquid separator through a phenol introduction port and discharging a mixed stream of the phenol with said adduct of crystallized bisphenol A and phenol; heating said phenol stream through a first heat exchanger before introducing the phenol stream through said phenol introduction port; melting the adduct of crystallized bisphenol A and phenol in the mixed stream flowing out from said phenol introduction port through a second heat exchanger to discharge a molten stream; and introducing said discharged molten stream to recrystallize bisphenol A through a second crystallizer.
