Acetone Recovery Unit For Water-based Polyurethane Industry
Distillation column is a tower-type vapor-liquid contact device for distillation, also called distillation column. There are two main types: plate tower and packed tower. According to the operation mode, it can be divided into continuous distillation column and batch distillation column. The basic principle of distillation is to partially vaporize and partially condense the liquid mixture for many times, and realize the unit operation of separation purpose by using the characteristics of different volatilities of each component. Distillation can be divided into simple distillation, flash distillation, rectification and special rectification according to its operation methods.
Distillation tower-suitable for concentration and recovery of various solvents;
1.Alcohol recovery system
Scope of application: Recovery and concentration of low-concentration solvents such as methanol, ethanol and acetone.
2.Anhydrous alcohol recovery system
Recovery and concentration of solvents that can be azeotropic with water, such as isopropanol and acetic acid.
3.DMF DMAC recovery system
Recovery and concentration of N, N-2 dimethylformamide (DMF), N, N dimethylacetamide DMAC, toluene and other solvents.
4.Acetic acid recovery system Scope of application
Suitable for esters and solvents with low solubility in water.
5.Biodiesel decolorization+deslagging system
The stock solution to be treated: biodiesel, also known as fatty acid methyl ester, refers to the use of various animal and vegetable oils as raw materials, which are modified by cross esterification with low-carbon alcohols such as methanol or ethanol to make it a fuel for internal combustion engines.
