Distillation column

Fractionating column

A distillation column is a tower-type vapor-liquid contacting device used for distillation, also known as a distillation tower. There are two main types: plate-type towers and packed towers. Based on the operating method, they can be further divided into continuous distillation towers and batch distillation towers. Operation pressure categories include atmospheric, pressurized, and vacuum. The basic principle of distillation involves multiple partial vaporization and condensation, utilizing the different volatility of its components (relative volatility, α) to achieve separation. Distillation can be categorized by its operating method into simple distillation, flash distillation, ordinary distillation, and special distillation, among others.

       Distillation Tower - Suitable for solvent concentration and recovery of various types
1. Alcohol Recovery System
Application Range: Recovery and concentration of solvents such as low-concentration ethanol and acetone.
2. Anhydrous Alcohol Recovery System
Recycling and concentration of solvents like isopropyl alcohol and acetic acid that form azeotropes with water.
3. DMF DMAC Recovery System
Recycling and concentration of solvents such as N,N-dimethylformamide (DMF), N,N-dimethylacetamide (DMAC), and N,N-2-methylformamide.
4. Acetic Acid Recovery System
Application Range: Suitable for esters and solvents with low water solubility.
5. Biodiesel Decolorization and Dewatering System
Unprocessed Feedstock: Biodiesel, also known as methyl ester of fatty acids, refers to a fuel produced by modifying various animal and vegetable oils or fats through transesterification reactions with低碳 alcohols like ethanol, making it suitable for use in internal combustion engines.
Processed products obtained: Light fractions + golden diesel + residue oil
6. Waste Oil De-coloring and Dreg Removal System
Raw materials to be processed: waste oil including emulsion oil, transformer oil, gear oil, hydraulic oil, and waste engine oil (black oil)
Processed products: Light oil + Golden diesel/basis oil + Residue oil
7. Self-adhesive Mixed Solvent Recovery System
MCPD methylcyclopentadiene dimer + MMT methylcyclopentadiene tricarbonyl manganese + MCP methylcyclopentadiene monomer + resin, etc., mixed solvent
The above distillation tower/distillation recovery system can achieve both batch and continuous recovery. The raw liquid processing capacity range is 0.5t/h to 500t/h.
