The production method of furfural everybody should somewhat hear of, so affirmative also know to be able to use destilling tower in this link, is that destilling tower is in this craft basically what to item be in charge of? Be also furfural what is the practical effect of the destilling tower in making?
In a variety of means, for commonly used is finish two paces to react at the same time in boiler of a hydrolyze and generate furfural, and the activator with different basis is mixed hydrolysis equipment uses different hydrolysis technology. our country, it is with what boiler of hydrolyze of erect type intermittence uses general, mix raw material in loading hydrolysis boiler later, can undertake vapour heats directly, make thereby generated furfural tape gives hydrolysis boiler. After the steam condensation that contains furfural, can be sent primary tower distill, refrigeration arrives constant temperature when superstratum sends content of low boiling point destilling tower, eliminate returns primary tower to reclaim after content of low boiling point furfural; And lower level thick furfural sends dehydration tower and purificatory tower treatment. This shows, destilling tower uses thing of purify low boiling point.
