I have an extract tower facility to extract triethyl phosphate with toluene solvent, in a ceramic packing tower type, at a temperature of 20 C, 1 Bar,

How is a simple method to calculate the performance of the extract tower? I want to increase the extract yield so that the raffinate is purer. Is there any need for other facilities?

 

Cocurent type, feed 6 m3/h, solvent 10 m3/h, raffinate about 3 m3/h.

 

Thanks for your attention

 

Note: i don t know the number of stage but I guess it is 3 stages.

Hi,

Difficult to support with so little information. No data about the partition coefficient of your system.

A good start is to increase the solvent flowrate and observe the quality. At the same time observe the hydraulic of the column. this could be the bottleneck, flooding.

Good luck
