Extraction towers play a key role in the liquid-liquid extraction process, and in order to improve their performance, the following strategies can be adopted.

First, optimize the internals. Selecting suitable packing or sieve plate is an important measure to improve the performance of extraction column. Different types of fillers have different specific surface area and void ratio, which have a significant effect on the mass transfer efficiency.

For example, the structured packing has a high specific surface area and good fluid distribution performance, which can improve the mass transfer efficiency and reduce backmixing. For some extraction processes requiring high mass transfer efficiency, structured fillers can be selected. At the same time, regular inspection and cleaning of internal components to prevent its blockage or damage, affecting the extraction effect.

Secondly, precise control of operating parameters. Operating parameters such as temperature, flow rate and extractant dosage have important effects on the performance of the extraction column. The change of temperature will affect the solubility and mass transfer coefficient of the solute, which need to be precisely controlled according to the specific extraction system. Too fast flow rate may lead to inadequate mass transfer, and too slow flow rate will reduce production efficiency, so it is necessary to determine a better flow rate through experiments. The amount of extractant also needs to be reasonably controlled, too much extractant will increase the cost, too little may lead to incomplete extraction.

Furthermore, advanced control technology is adopted. The automatic control system is introduced to monitor the operation parameters of the extraction tower in real time, such as temperature, pressure, liquid level, etc., and automatically adjust the operation parameters according to the set target values. This can improve the stability and accuracy of operation, reduce the influence of human factors, and improve the performance of the extraction column.

In addition, the extraction agent was optimized. Selecting extractant with good performance is the key to improve the extraction effect. Research and develop new extractants to improve the selectivity and extraction ability of solutes.

At the same time, the extraction agent is recovered and recycled to reduce production cost and environmental pollution.

Finally, carry out regular maintenance and maintenance of equipment. Regular inspection of the extraction tower body, internal components, sealing devices, etc., timely detection and treatment of equipment failures and hidden dangers. Keep equipment clean to prevent dirt and impurities from affecting equipment performance. Through the optimization of internal components, precise control of operating parameters, using advanced control technology
