Regarding the design of the extraction tower.
Thread Content
The product in the heavy phase during the production process contains about 5% of this component; it has a very high viscosity, and the heavy phase is highly corrosive. Now, I want to extract those 5% of products from the heavy phase. Please help me come up with some ideas on how to solve this. If it has economic value, I’ll pay for it.
Physical and chemical data for the various components of the heavy phase should be provided to encourage collective brainstorming.
First, select the extractant and determine the heavy phase and the light phase. Second, determine which phase is the continuous phase. Third, select the appropriate filler type based on the physical properties of the material. Finally, the appropriate residence time is determined based on the extraction efficiency, thereby calculating the yield.
The key is to choose the extractant, as it determines the efficiency of extraction； Then there are the extraction equipment; today’s extraction towers are no longer simple static devices – rotary disk extraction towers and pulse towers can improve extraction efficiency
The extractant is the most important factor; for continuous systems, appropriate packing should be selected, and ceramic packing with sieve plates is recommended
Select an appropriate extractant; it is best to combine it with 5% by weight in order to alter its physicochemical properties. If the viscosity can be reduced after extraction, pressure distillation can be considered, allowing the material to be directly sent to the next processing step and thus addressing the issue of corrosion of the pumps caused by the material
If a rotary extractor is to be used, it is necessary to select an appropriate extractant, determine the solvent ratio, control the rotation speed of the rotor, and adjust the phase interface.

It’s too general; it would be better to tell people what the heavy phase is, what the viscosity is, what the product is, and what the production capacity is. Only then can everyone provide reasonable suggestions, such as which extractant to use, whether to employ a rotary extractor tower, a vibrating extractor tower, or a mixed sedimentation tank.
The selected extractant should be heavier than the light phase corresponding to the heavy phase you mentioned, so as to facilitate extraction; then determine the solvent ratio
