Description
Technical field
The utility model relates to the refining plant system of thick terepthaloyl moietie in a kind of terepthaloyl moietie industrial production.
Background technology
Terepthaloyl moietie is a kind of important Organic Chemicals.Be mainly used in and make trevira, frostproofer, nonionogenic tenside, thanomin and explosive etc.; The maximum purposes of terepthaloyl moietie is to be used for producing polyester; Be one of two big important source material of production of polyester; The quality of its quality directly influences the production stability of polyester, even the quality of product is caused significant effects.Ultraviolet transmittance one uV value is one of important symbol of industrial terepthaloyl moietie quality product.Synthetic gas preparing ethylene glycol device is since drive, and other quality index all is in steady state, has only 220nm, the appearance of the uV of 275nm place value to fluctuate.Terepthaloyl moietie is as the raw material of trevira, because the existence of micro-content organism. can have influence on quality of fiber.So, these impurity organism are controlled at bottom line, the quality of raising terepthaloyl moietie product and the quality of trevira are played important effect.Ultraviolet ray transmissivity is an important indicator of estimating the terepthaloyl moietie quality product, and it is low influence impurity content in product of ultraviolet ray transmissivity, complete separation difficulty.The ultraviolet ray of the terepthaloyl moietie product of world-renowned petro-chemical corporation such as shell, BASF AG etc. (275 nm) transmitance is 95%.The terepthaloyl moietie product that China produces, also there is a certain distance in its ultraviolet ray transmissivity, and this will influence the market competitiveness of homemade terepthaloyl moietie.So the research that improves the terepthaloyl moietie ultraviolet ray transmissivity is the needs of industry.Through research, find out the reason that influences the terepthaloyl moietie ultraviolet ray transmissivity, improve the terepthaloyl moietie ultraviolet ray transmissivity, this improves the quality to improving the production technology of Chinese terepthaloyl moietie, strengthens the competitiveness of product in market, has great importance.
Summary of the invention
The purpose of the utility model is to provide a kind of refining plant system of thick terepthaloyl moietie that can the terepthaloyl moietie quality product.
The refining plant system of thick terepthaloyl moietie in the terepthaloyl moietie industrial production of the utility model; Comprise the terepthaloyl moietie rectifying tower, connect the tower still water cooler of terepthaloyl moietie rectifying tower outlet and the terepthaloyl moietie product groove that is connected with tower still water cooler; The terepthaloyl moietie filter vat of dress anionite-exchange resin in being provided with on the pipeline between tower still water cooler and terepthaloyl moietie product groove; The import of said terepthaloyl moietie filter vat is connected with the terepthaloyl moietie material outlet of tower still water cooler, and the outlet of said terepthaloyl moietie filter vat is connected to the import of terepthaloyl moietie product groove.
The terepthaloyl moietie filter vat of dress anionite-exchange resin can be removed two ketone impurity well in the utility model was set up in the refining system of thick terepthaloyl moietie, had improved terepthaloyl moietie quality product and ultraviolet ray transmissivity.

Embodiment
The refining plant system of thick terepthaloyl moietie in the terepthaloyl moietie industrial production of the utility model; Comprise terepthaloyl moietie rectifying tower 2, connect the tower still water cooler 3 of terepthaloyl moietie rectifying tower 2 outlets and the terepthaloyl moietie product groove 4 that is connected with tower still water cooler 3; The terepthaloyl moietie filter vat 6 of dress anionite-exchange resin in being provided with on the pipeline between tower still water cooler 3 and terepthaloyl moietie product groove 4; Wherein the import of terepthaloyl moietie filter vat 6 is connected with the terepthaloyl moietie material outlet of tower still water cooler 3, and the outlet of terepthaloyl moietie filter vat 6 is connected to the import of terepthaloyl moietie product groove 4.
The thick terepthaloyl moietie that the synthetic gas preparing ethylene glycol is produced is after three rectifying tower rectifications under vacuum, by the terepthaloyl moietie of side line extraction concentration＞99%, after the cooling of tower still water cooler; The terepthaloyl moietie hay tank of exchange resin is equipped with in entering; After the filtration, get into terepthaloyl moietie product groove, by the pump entrucking.The terepthaloyl moietie filter vat of dress anionite-exchange resin can be removed two ketone impurity well in the utility model was set up in the refining system of thick terepthaloyl moietie, had improved terepthaloyl moietie quality product and ultraviolet ray transmissivity.
