These images show a flowsheet and stream summary of a reactor from a chlorobenzene plant. This reactor is a washer that functions to rid the system of hydrochloric acid using a caustic stream that contains a solution of sodium hydroxide. This reactor creates sodium chloride and water, with water being released into a waste stream, and sodium chloride being released through a crude stream that also contains various reactants and products from earlier in the process, such as benzene, chlorine, chlorobenzene, P-dichlorobenzene, and unreacted sodium hydroxide solution. The stream summary displays specific values associated with the composition and thermodynamics of the input and output streams of this reactor.
