Phthalic Anhydride Plant

Plant# 302
Capacity 22,500 TPY

Plant Description

Phoenix Equipment Corporation has this used Phthalic Anhydride plant immediately available. The process of the PA production takes place in two tubular reactors and is based on the catalytic oxidation of orthoxylene with air oxygen. Mixture of hot air and orthoxylene is continuously added in reactor, where are installed ceramic rings covered with vanadium pentoxide, which catalyzes the reaction. Crude Phthalic anhydride is thermally treated and then led to the distillation into two columns. Cold gas, from which we excluded phthalic anhydride, is leaving the separator as a waste gas. The incinerator is equipped with a metering pump, metering nozzles, fans of the primary and secondary air, and two supporting burners on fuel oil.
