Applicable scope
This equipment is suitable for pharmaceutical, food, light industry, chemical industry (1) separation of liquid mixture, only the mixture of the boiling point of the ingredients have a greater difference in order to achieve a more effective separation; (2) Determination of pure compounds boiling point ; (3) purification, by distillation with a small amount of impurities in the material to improve its purity; (4) recovery solvent, or part of the solvent to evaporate to concentrate solution.

 

Equipment composition
The equipment is intermittent and continuous two forms, mainly by the tower kettle, tower, condenser, balance tank, cooler, flowmeter and other components.

 

Main feature
1. Continuous with preheater, can be continuous production, in line with the needs of mass production.
2. The equipment and materials are part of the contact with stainless steel, with good corrosion resistance, and energy saving, environmental protection, Yang's production costs and improve efficiency advantages.
3. The tower is made of removable U-type, easy to heat the outer wall and the inner wall of the distillation tank.


Specific application

 

Alcohol solvent recovery
1. Scope: low concentration of methanol, ethanol, propylene unit of the same solvent recovery, enrichment.
2. Process characteristics: continuous recovery process, the recovery rate is greater than 95%, the bottom of the waste liquid containing low, stable product concentration, distillation operation costs low, investment province.
3. Processing capacity: daily processing 1T-200T.

 

Anhydrous alcohol recovery
1. Scope: isopropyl alcohol, acetic acid and other water can produce azeotropic solvent.
2. Process characteristics: intermittent or continuous extraction process, the recovery of high purity products, low water content, high yield, waste discharge rate is low, energy consumption, extraction agent recycling, consumption less, operating costs low.
3. Processing capacity: daily processing 1T-100T.

 

DMF DMAC recovery
1. Scope: for N, N-2 methyl formate (DMF), N, N dimethyl ethyl phthalamide DMAC, toluene and other solvent recovery
2. Process characteristics: continuous negative pressure distillation process, the recovery of high concentration of finished products, stable quality, low content of waste liquid. Negative pressure operation consumption steam province, the recovery rate is high, the benefit is remarkable.
3. Dispose of: daily processing 1T-50T.

 

Acetic acid recovery
1. Scope: Suitable for esters and low solubility of water with the solvent
2. Process characteristics: continuous production process, the finished product quality and stable waste discharge rate is low, consumption of gas, high recovery rate of distillation, up to 95% or more, recycling and installation, wide application.
3. Disposal amount: 1T-1100T daily.
