Theoretical and experimental analysis of venting-induced processes in reacting and non-reacting two-phase systems

Top venting of initially saturated methanol and water and of a reacting methanol/acetic anhydride mixture has been carried out in a semi-technical scale test facility. Measured variables were the pressure in the reactor and the catchtank and mass flow rate and quality in the vent line. The experimental results compare satisfactorily with predictions obtained by using an in-house modified version of the safire code
