Product description

Parameters

After years of collaborative research with the Department of Chemical Engineering at Tsinghua University, our company has developed a new technology for honeycomb (FG) series structured packing extraction towers, which has been successfully applied in liquid-liquid extraction processes such as furfural refining, propane deasphalting, and extraction and dephenolization of phenolic wastewater. Practice has shown that the high-efficiency extraction tower has the advantages of large processing capacity, low pressure drop, high mass transfer efficiency, and easy processing, manufacturing, and maintenance.

1) Filler characteristics:

1. By using FG type fillers to transform traditional rotary and packed extraction towers, the production capacity can be increased by more than 50%. When designing a new device, under the same processing capacity, the tower diameter can be reduced, equipment investment can be reduced, and the floor area can be reduced.

2. The porosity is large and can reach over 96%, with strong anti clogging performance.

3. The specific load of the tower is about 1.5 times that of traditional extraction towers.

4. High mass transfer efficiency ensures high extraction efficiency when the specific load of the tower is high.

5. Long service life, easy to maintain and reuse.

6. The smooth surface of FG type fillers can achieve enhanced clarification and separation, and reduce phase entrainment.

2) Filler classification:

Type I - light plate (used for coalescence settlement section);

Type II - circular pore (FG - Ⅱ - K) or tongue shaped pore (FG - Ⅱ - S) (used for mass transfer in extraction);

Type III - Support redistribution packing (used for support redistribution)

Static Mixer

The mixing process of a static mixer is carried out by a series of mixing units of different specifications installed in a hollow pipeline. Due to the role of the mixing unit, the fluid rotates left and right at times, constantly changing the flow direction, not only pushing the central liquid flow towards the periphery, but also pushing the surrounding fluid towards the center, resulting in a good radial mixing effect. At the same time, the rotation of the fluid itself also occurs at the interface of adjacent components. This perfect radial circulation mixing effect significantly reduces the temperature gradient, velocity, and mass gradient of the fluid on the pipeline cross-section, promoting the "cutting", "displacement", "rotation", "overlap" and other movements of immiscible fluids in the pipeline, thereby achieving good mixing effect.
