| titleOfInvention | A kind of method of purification of durol |
| abstract | The present invention relates to a kind of method of purification of durol, durol solution (4) enters in freezing and crystallizing device (1) and carries out freezing and crystallizing, the discharge (12) entering (11) and heat-eliminating medium of this freezing and crystallizing device heat-eliminating medium, obtain low-temperature receiver, after freezing and crystallizing, obtain the durol xln (5) containing crystalline mother solution; Be separated by crystalline mother solution with centrifugal separating device (2), obtain crystalline mother solution (7) and centrifugal rear solid phase prod (6), this solid phase prod adopts squeezing machine (3) to squeeze, and obtains durol product (8), and the crystalline mother solution squeezed out (9).The present invention gives a kind of method of purification of durol, by obtaining the durol of higher concentration, huge economic benefit and social benefit can be had. |
