摘要:
A system for producing phenol and bisphenol A comprising: a first production unit for producing phenol comprising a decomposition reaction unit and a purification unit; a second production unit for producing bisphenol A comprising a reaction unit and a concentration unit; and a removal unit for removing methanol and acetone during the production of phenol and bisphenol A. The removal unit includes a removal column comprising an overhead purge part, a bottom recirculation part and a supply part. The supply part comprises a purification unit discharge part to supply methanol, acetone, and water discharged from the purification unit to the removal column and a concentration unit discharge part to supply phenol, acetone, and water discharged from the concentration unit to the removal column, and is provided to the midsection of the removal column.
