I found this while looking for Calgren permit activity in the Golden State. No luck with that yet - but this is interesting material put out by the California Air Resources Board (ARB) two months ago:
See Here
"ARB staff’s estimate of the carbon intensity (CI) of corn oil biodiesel is based on information made available by Greenshift Inc.—a company that has commercialized a corn oil extraction process. Although Greenshift’s is not the only available extraction process, more information is publicly available on its process than is available on alternative systems."
"Under the Greenshift process, corn oil is removed from the DGS process stream through a combination of washing and centrifuging. The extracted corn oil is shipped to a biodiesel production plant where it is converted to fatty acid methylester (FAME) biodiesel using a transesterification process—the same process that is used to produce biodiesel from soy oil and other oil- and fat-based feedstocks."
"The equipment used to extract corn oil at corn ethanol plants consumes both thermal and electrical energy. This additional energy consumptions is more than offset, however, by energy savings realized during the DGS drying process. Energy is saved because the removal of corn oil both reduces the mass of the DGS entering the dryers, and improves the efficiency with which that DGS transfers heat. Based on information from Greenshift, ARB staff estimates that the production of corn oil at an ethanol plant reduces the net energy consumption of that plant by about nine percent.'

PS A government agency gives kudos to GreenShift for its comparitive openess. That's news. ;~) Remember the US EPA used GreenShift throughout its RFS2 and also RFS2 HERE. (Last two links are big downloads)
Although Greenshift’s is not the only available extraction process, it's the only legal, patented, most efficient, highest yielding one.

ReplyDeleteThe other systems are disputed as illegal infringing systems. GreenShift is litigating their providers and users in court for patent infringement.
He's baaack-
ReplyDeleteAnother bulky big block gobbled up under cover of form t after close. Bidding up 57,500 @ .1643 pushed the ask to .2.
You guys see the 35,100
GreenShift needs a court victory to remove the confusion from the industry as to who's COES they need to use. They should all know there is only 1 process and it's patented by GreenShift and they must license with them. They should not be confused or enticed by ICM or Poet thinking they won't need to pay the royalty. As COES tech is very important to the corn ethanol industry we need a decision on the infringement issue and they need it soon because the demand for the COES is really picking up, producers need to know what to choose and what's legal.
ReplyDeleteThe confusion must be eliminated.
The date is November 4
ReplyDeleteI doubt they were aware of the Markman results at the time.
Definitely were not aware of other process rejected patents.
It is a preliminary draft. Maybe revised edition will make corrections.
