It’s all good, misunderstandings happen!
We’re all here to try to help each other and share knowledge.
And you’re right, this is not a process that I would recommend to anyone if they were not doing colder ethanol already.
This adjustment could make their existing system more efficient, but it’s not going to be one that I would recommend a friend install if they are building a new extraction system.
Note: I’m not a patent attorney. Unsolicited advice is worth what you paid for it.
With Delta owning that patent, and Delta being owned by a VC fund, I would not recommend anyone make money off something that infringes their IP. With that said, don’t sell sprayballs or nozzles on centrifuges and you are probably fine.
Then again, if you’re big enough to be targeted by them on a patent suit, you’ve probably got the ability to access enough debt that you can leverage into a much better system than a chilled ethanol spray system, and you’re not looking in the area of their IP anyways.
