Distillation: equipment and process

DEGONG is a manufacturer and supplier of distillation equipment and beer brewing equipment. Distillation is the process of separating the components of a liquid mixture by alternating evaporation and condensation. Distillation can result in substantially complete separation, resulting in almost pure components, or it can result in partial separation, resulting in higher concentrations of components in a particular combination. Distillation takes advantage of the volatility changes in the components of the mixture.

Distillation equipment specifications

The distillation process including the following stages is used to recover alcohol:

  • Intermittent or continuous distillation vessels process alcohol.

  • By using conductive heat transfer, the heating jacket heats the alcohol.

  • Vacuum can be applied to the container to lower the boiling temperature of alcohol.

  • Alcohol changes from liquid to vapor when it reaches its boiling point.

  • The clean alcohol vapor passes through a condenser with a condensing and subcooling section. The alcohol returns to a liquid state in the condenser, where it is cooled to room temperature.

  • Impurities are not transferred through the vapor phase and remain in the discharge port to be released.

Distillation design and technology

Distillation is an important stage or "unit operation" in many industrial processes because it is one of the most reliable and cost-effective chemical separation methods. DEGONG is a distillation supplier of distillation systems, suitable for various industries, including:

  • Petrochemical

  • General chemical production

  • Renewable fuel

  • food processing

  • Pharmaceutical

  • agriculture

  • mining

Distillation is a heat and mass separation technology. Although there are many ways to separate compounds, in many cases, distillation has proven to be the most reliable and cost-effective solution.

Single-stage and multi-stage separation processes

Before getting into the mechanics and design issues of the distillation process, it is important to understand the general difference between single-stage and multi-stage separation methods.

Evaporation, or the more specialized but less common "flashing", is a single separation stage. By heating and boiling the solution, a volatile component can be eliminated. The more volatile components in the solution are evaporated and eliminated from the equation.

In the separation process, multi-effect evaporation uses multi-phase evaporation. The sequential process design in multi-effect evaporation limits the procedure. The distillation equipment service uses the same multi-stage method in the counter-current stage to make the process more efficient and waste-free.
