Improved phthalic anhydride process |
| abstract |
Disclosed is an improved process for the production of phthalic anhydride wherein the spent catalyst is removed from the oxidation reactor tubes more effectively by vacuuming from the top and using a vacuum hose having a tip with an increased impact strength and with a maximum hardness. As a result, the new catalyst loading can be made more uniform and the process may be operated with improved stability at higher organics loadings in the reactor feed. Process stability may be further improved by varying the outlet temperature of the phthalic anhydride precondenser over time. |
