Abstract
The invention discloses a kind of recovery method of alcohol, the recovery method of described alcohol is the alcohol recycle method in the production technology of cumyl peroxide, and its concrete operations is as follows：In the production technology of cumyl peroxide, DCP finished products crystallization workshop section needs to be used as solvent using alcohol, liquid phase carries out profit extract and separate after using centrifuge separation of solid and liquid, special rectifying column is delivered to after aqueous phase is preheated to carry out continuing atmospheric distillation, tower bottoms can be taken out as fuel oil, liquid of top of the tower main component is alcohol, is collected after cooling with accumulator tank.Reusable edible of the present invention, energy-saving and emission-reduction reduce cost, and alcohol effluent is reclaimed, and can repeat to recycle, while the generation of security incident can be prevented effectively from, efficiently solve the influence that containing alcohol residue is caused to environment.
Description
Technical field
The invention belongs to alcohol recycle field, and in particular to a kind of recovery method of alcohol.
Background technology
Commercial scale DCP is, using isopropylbenzene as raw material, hydrogen peroxide isopropyl to be changed into by cumene oxidation reaction
Benzene CHP, and part CHP is generated into dimethyl benzyl alcohol DMCA by reduction reaction, then DMCA and another part CHP is condensed
Reaction generation DCP, finally carries out crystal refining processing to DCP products and obtains final products.
Traditional handicraft is directly taken out after separation is stayed overnight by centrifuge using liquid phase as fuel oil, causes substantial portion of
Alcohol and product are lost in, and add production cost.
The content of the invention
Goal of the invention：In order to solve the deficiencies in the prior art, the invention provides a kind of recovery method of alcohol.
Technical scheme：A kind of recovery method of alcohol, the recovery method of described alcohol is the life of cumyl peroxide
Alcohol recycle method in production. art, its concrete operations are as follows：In the production technology of cumyl peroxide, DCP finished product knots
Brilliant workshop section is needed using alcohol as solvent, and liquid phase carries out profit extract and separate after using centrifuge separation of solid and liquid, and aqueous phase is through pre-
It is delivered to special rectifying column after heat to carry out continuing atmospheric distillation, tower bottoms can be taken out as fuel oil, liquid of top of the tower main component
For alcohol, collected after cooling with accumulator tank.
It is used as optimization：Treatment temperature is 80 DEG C, and processing time is continuous processing.
Beneficial effect：Reusable edible of the present invention, energy-saving and emission-reduction reduce cost, and alcohol effluent is reclaimed, can
Repeat to recycle, while the generation of security incident can be prevented effectively from, efficiently solve the influence that containing alcohol residue is caused to environment.
Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, so that the technology of this area
Personnel can be better understood from advantages and features of the invention, so as to make apparent boundary to protection scope of the present invention
It is fixed.Embodiment described in the invention is only a part of embodiment of the invention, rather than whole embodiments, based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Embodiment
A kind of recovery method of alcohol, the recovery method of described alcohol is in the production technology of cumyl peroxide
Alcohol recycle method, its concrete operations are as follows：In the production technology of cumyl peroxide, DCP finished products crystallization workshop section needs
Using alcohol as solvent, liquid phase carries out profit extract and separate after using centrifuge separation of solid and liquid, is delivered to after aqueous phase is preheated
Special rectifying column carries out continuing atmospheric distillation, and tower bottoms can be taken out as fuel oil, and liquid of top of the tower main component is alcohol, cooling
Collected afterwards with accumulator tank.Treatment temperature is 80 DEG C, and processing time is continuous processing.
Reusable edible of the present invention, energy-saving and emission-reduction reduce cost, and alcohol effluent is reclaimed, and can repeat again sharp
With while the generation of security incident can be prevented effectively from, efficiently solving the influence that containing alcohol residue is caused to environment.
