Rectification tower is the current mechanism of chemical industry, its importance cans be imagined, when the rectification tower of different form is undertaking solution is handled differring, the means that its use also is distinguishing. tower of double extractive rectify, it can realize the depart of a variety of complex solution, specific be how accomplish?
If here has ester of armour of a kind of acetic acid, methanol, alcohol, benzene, water,wait for the mixture solution of material, our requirement is to use tower of double extractive rectify its all sorts of composition get effective depart, how should be done? The method that adopt is what put mixed liquor into rectification tower a side is medium bottom, and cat head stabilizes control fall in certain limits, the water in mixing solution through heating so can be evaporated, thereby the mixed liquor of the ester of acetic acid armour of tall purity, methanol, alcohol and benzene. At this moment the temperature of another side cat head of tower of double extractive rectify also should get controlling, get prep above with this 99% methanol solution; Pour out of the mixed liquor that contains extractive agent to pass further processing even from tower boiler, through second birth tower its depart receives solution of 48% above alcohol; The solution that remain reachs the two side of rectification tower through ceaseless loop.
