Mechanical Vapor Recompression Energy-Saving Distillation Technology

Main Advantages and Characteristics:

1.Wide Temperature Difference Range: Applicable to distillation systems with a temperature difference within 50°C between the top and bottom of the column.

2.Significant Energy Saving: The heat exchange is carried out between the heat exchanger and the top steam of the tower. The resulting clean water vapor is compressed by the compressor and then returned to the bottom of the tower for use, thereby saving a significant amount of steam consumption and achieving remarkable energy-saving effects.Saves 50-80% steam consumption compared to traditional distillation for methanol, ethanol, and ammonia purification.

3.High Safety Performance: Uses indirect heat exchange to prevent light components or corrosive gases from entering the compressor.

4.Good System Stability: Equipped with an intelligent control system for real-time parameter adjustment. Keep the distillation process in the best condition all the time. Enhances the flexibility of production, enabling it to adapt to various production conditions, strengthens the stability of the system, reducing the decline in product quality and the occurrence of production accidents caused by operational fluctuations.
