Tullis also worked with Edward Cohn at Harvard to develop the Cohn fractionator, now used around the world to prepare human platelets, the molecular disks associated with clotting.

A "'protein skimmer "'or "'foam fractionator "'is a device used to remove organic compounds such as food and waste particles from water.

Residual oil from the vacuum distillation unit ( sometimes including high-boiling oils from other sources within the refinery ) is pumped into the bottom of the distillation column called the main fractionator.
24.
If the CE is larger than that value, then the only option available in the optical fractionator method is to increase the counting by either using more slices or more sampling sites on the slices.
25.
Pumping the incoming residual oil into the bottom of the main fractionator, rather than directly into the furnace, preheats the residual oil by having it contact the hot vapors in the bottom of the fractionator.

27.
Part of that slurry oil is recycled back into the main fractionator above the entry point of the hot reaction product vapors so as to cool and partially condense the reaction product vapors as they enter the main fractionator.

Although the schematic flow diagram above depicts the main fractionator as having only one sidecut stripper and one fuel oil product, many FCC main fractionators have two sidecut strippers and produce a light fuel oil and a heavy fuel oil.

In that context, reflux refers to the portion of the overhead liquid product from a distillation column or fractionator that is returned to the upper part of the column as shown in the schematic diagram of a typical industrial distillation column.
