New Patent Ap/Method II

I had reported on a new patent application yesterday, but with all the blogs/information flying around, I wanted to take a closer look today.  Figure two is labeled Whole Stillage "Mechanical Separation".
"FIG. 2 is a partially schematic flow chart illustrating the recovery of oil from a syrup formed by evaporating the thin stillage;"*

"FIG. 11 is a schematic flow chart illustrating a technique and system for washing whole stillage to maximize oil recovery."*  From the GERS web site:  "The Method II process washes the whole stillage in a series of additional centrifuges upstream of the normal centrifugation stage of the ethanol plant."

These figures are all from a 50mmgy plant. 

Here are all 11 Full size Diagrams

Here is the Application with much more Detail (has *quotes above)

What I can see here is the total corn oil value produced goes $102/hr to $426.45/hr - with a much smaller % increase in energy usage.  Total product value shoots up over three times.  Of course the capital outlay would be more initially.   Here is a more detailed explanation of Method II from the GERS web site:

"The Method II process washes the whole stillage in a series of additional centrifuges upstream of the normal centrifugation stage of the ethanol plant. This causes the oil concentration in the centrate flow noted above to increase, which in turn increases the amount of oil extracted by the Method I process. Method I can extract up to about 3 gallons for every 100 gallons of ethanol produced. Method II can add another 3.5 gallons of corn oil for every 100 gallons of ethanol produced. We have other additional methods in development to increase these yields further."

"In addition, Calgren has agreed to install GreenShift’s first Method II Corn Oil Extraction System to extract corn oil from Calgren’s whole stillage. With Method I (thin stillage extraction) and Method II (whole stillage extraction). GreenShift stated that corn oil yields that could be as high as 1.33 pounds per bushel and having at least one advanced technology as described in the final rule for the expanded RFS2 published by the U.S. Environmental Protection Agency on December 21, 2010."  Remember Here

My SkunK kingdom for a positive update from Calgren by anyone!  OK, how about the back 40?  Would you believe two chemical hand warmers and I'll shovel your driveway?  lol
