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.
