| titleOfInvention | A kind of efficient catalytic rectifying column being esterified for ethylene glycol and acetic acid |
| abstract | The invention discloses a kind of efficient catalytic rectifying columns being esterified for ethylene glycol and acetic acid: from top to bottom include three parts inside tower: top is rectifying section, middle part is catalyst reaction section, lower part is stripping section, rectifying section and stripping section are filled with tower internals, and catalyst reaction section is filled with the combination structured packing of loading catalyst.Tower top be equipped with gaseous phase outlet, tower wall top be equipped with refluxing opening, tower wall middle and upper part be equipped with excess monomer import I and its be connected with the bottom of rectifying section or tower wall middle and lower part be equipped with excess monomer import II and its be connected at the top of stripping section；The mixture intake of ethylene glycol, acetic acid, ethylene glycol acetate, glycol acetate is equipped in the middle part of tower wall, and it is connected with the lower part of catalyst reaction section, tower bottom is equipped with discharge port；Gaseous phase outlet is connected with condenser, and the outlet of condenser is connected with split-phase slot.The present invention solves the technical problem of catalytic rectifying tower catalysis and separating capacity deficiency that ethylene glycol and acetic acid are esterified. |
