(110e) Liquid Extraction Processes & Equipment

What is the best way to remove C₆, C₇ and C₈ compounds from a feed stream containing C₆, C₇ and C₈compounds?  How do you take a lubricating oil and remove certain compounds and improve its viscosity index (so that its viscosity does not change excessively with the oil’s temperature)?  What is propane deasphalting?  The answers to all of these questions in “liquid extraction processes.”

What technology was supported and funded by the actor Kevin Costner to help clean up the large 2010 Gulf of Mexico oil spill?  What are Karr reciprocating plate columns, Oldshue-Rushton contactors and Podbielniak centrifuges?  What the heck is a Graesser Raining Bucket?  The answer to all of these questions is “liquid extraction equipment.”

Imagine heavy and light fluids flowing vertically past each other with only a very small density difference.  Imagine rotating equipment that works better without rotating.  Liquid extraction is different – very different.  Do you know of any experts?  The authors are looking for one.
