| titleOfInvention | Dibasic acid methyl ester production system |
| abstract | The utility model discloses a dibasic acid methyl ester production system, include: the esterification kettle is used for reacting dibasic acid and methanol to generate dibasic acid methyl ester, the outer wall of the esterification kettle is provided with a heating jacket, the top of the esterification kettle is provided with a gas discharge port, and the bottom of the esterification kettle is provided with a product outlet; the rotating bed is used for separating the methanol/water mixture discharged from the esterification kettle and recovering to obtain methanol and water; a condenser for liquefying part of the separated methanol; a methanol receiving tank for receiving liquefied methanol and partially returning the liquefied methanol to the rotating bed; and the blower is used for returning the gaseous methanol part obtained by separation and recovery of the rotating bed to the esterification kettle. The utility model discloses production system passes through the revolving bed separation with excessive methyl alcohol/water mixture to directly return the methyl alcohol of gaseous state and esterify the cauldron, for returning the cauldron of esterifying after with the methyl alcohol condensation and reduced the energy consumption, improved the methyl alcohol utilization ratio, reduced manufacturing cost. |
