PURPOSE: A method for improving reaction yield and waste heat recovery in a styrene monomer manufacturing process is provided to increase lowers the pressure of a reactor and increases pressure of an azeotropic evaporator by installing additional a compression pump. CONSTITUTION: In a method for improving reaction yield and waste heat recovery in a styrene monomer manufacturing process, an apparatus for manufacturing a styrene monomer comprises a dehydrogenation reactor, heat exchanger, azeotropic evaporator, a separating tank, a distilling column, and a compression pump of the rear side of the separating tank, wherein an additional compression pump is installed between the rear side of the heat exchanger and the front side of the azeotropic evaporator. |
