Abstract:
A process for the production of vinyl acetate in a fixed bed reactor, said process comprising the steps of:(i) providing a pipe having a bend and a flow-correction device downstream of said bend,(ii) coupling the pipe to a fixed bed reactor comprising a reactor bed,(iii) providing a nozzle which is mounted to an end of a support arm,(iv) positioning said nozzle in said pipe such that said nozzle is located downstream of said bend and downstream of said flow-correction device, and said support arm extends into said pipe in a direction substantially parallel to the direction of said pipe downstream of said bend,(v) feeding a reactant process stream comprising acetic acid, ethylene and oxygen into said reactor along said pipe,(vi) feeding a catalyst promoter fluid into said reactant process stream through said nozzle to deposit said promoter over said catalyst bed, and(vii) reacting said ethylene, acetic acid and oxygen containing gas in said reactor to produce vinyl acetate.
