Research on safety Relief of Methanol-acetic Anhydride System Under Various Process Conditions

Safety relief is one of the most cost-effective technical measures for reducing risks of a reaction system under a runaway condition. Therefore, in order to investigate the design of a relief port, research on a 38.6wt% methanol-acetic anhydride system was carried out by using a high-performance adi...

Description
Summary:Safety relief is one of the most cost-effective technical measures for reducing risks of a reaction system under a runaway condition. Therefore, in order to investigate the design of a relief port, research on a 38.6wt% methanol-acetic anhydride system was carried out by using a high-performance adiabatic calorimeter PHI-TEC II, and effects of different volumes of reactors and different masses of reacting substances therein on the area of the relief port were analyzed. Results indicate that the reactor volume has minor effects on the relief area, and an increased mass of reacting substances requires an increased relief area. At the same time, effects of different relieving pressures on the relief area were investigated, and it was concluded that a lower relieving pressure should be set in the design process.
