Plants for producing ethyl benzene/styrene
Special features
Production of ethyl benzene by means of liquid phase alkylation of benzene at the zeolith catalyst
Production of styrene by means of catalytic dehydrogenation of ethyl benzene with water vapor and under vacuum in 2 adiabatic radial reactors with external intermediate superheating
Less stringent requirements as to quality of input materials
High product purity
