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
