WEBINAR: Designing Liquid-Liquid Extraction Columns

In most chemical engineering curriculums, distillation and liquid-liquid extraction (LLE) do not receive equal billing. Yet, this powerful separations technology is in place across the CPI, pharmaceutical and oil/gas industries. Discover how to design an LLE column with industry experts Don Glatz and Brendan Cross as they discuss specific examples and separations challenges.
Presenters:
Don Glatz, Extraction Technology Manager
Brendan Cross, Senior Process Engineer
Moderated by:
Mauricio Villegas, Business Development Manager

awesome webinar!

[@Zuberzito]

Thank you very much for this amazing presentation. I will suggest it to my chemical engineering undergraduate students immediately. Please, keep posting videos like this! Regards from Brazil!

@20:50 explanation on when to use metal or plastic as your internal. Ie packing.

say i have a petroleum sludge oil.. required to recover oil by solvent extraction .. should i use Batch or centrifugal or tray! or what!

[@malleswararaoanupoju2357]

Sir good morning. I am.malleswara rao from vizag, a.p. India. Iam working in solvent recovery system since 10 years. I have a problem Sir. I don't separate methylene di chloride from hexane. Feed analysis is 70%MDC+30%Hexane. So please tell me Sir.

Great webinar guys! Maybe a small question regarding the interface location in packed column. Is the location decided by the bottom valve or by the phase flow-ratio's? Thanks a lot, Stef

[@publiccalendar9105]

Interface control is by the heavy phase outlet (bottom) valve. Interface location (top or bottom) is determined by how you start up the column. First you fill the column with one phase or the other. That sets the continuous phase. Once the column is full of the selected phase, then the other phase is added and it automatically becomes the disperse phase with the interface then set (by the bottom control valve) in the opposite end of the column from where the disperse phase is added.

@@publiccalendar9105 So startup is very important as well as a level instrument? I cant fill up the column with continuous phase for lets say 75% and then startup with the dispersed phase. Afterwards changing the interface with the bottom valve?
