Re: [siteplan] Fuel quality

Zac,

I was reading more about the 3/27 test on-line last night and the verdict was that washed fuel needed to be DRY, otherwise water may settle out.  This makes me think we should consider testing reacted fuel before the 5% wash is added, so there is no excess water to "cloud" the results.  

This is a learning experience like all the rest....

Thanks,

Felix

We need to run all the tests that we can for every batch and be rigorous about dealing with the results. It was my decision to wash and dry the "failed" fuel, because I wanted to see what happened to it through that process. We will test it again carefully after drying and determine whether it needs to be re-reacted, which is probably what will happen.

I feel fuel quality comes up once and a while, but then gets swept under the run b/c raw production takes presedence and coop memebers are willing to buy it regardless. I honestly don't feel we are churning out anything bad, but I do feel we need tighter quality control. These kinds of things are never a problem until its too late!! 
Lets get this back at the forefront of our planning/discussions!

Friends,

Thanks to all for some great work party accomplishments on Saturday.

I know we are working hard to get the reactors back on line, but I would 
like to discuss fuel quality. While we are at this pause in production, 
we need to re-examine the fuel quality issue. Zac has been testing our 
fuel with the 3/27 test and from what I have heard, none has passed. 
This test is reported to be a good quick indicator of biodiesel purity: 
no unreacted glycerindes.

I would like to suggest that we buy a sample of SeQuential from Blue Sky 
and test it just for fun.

I think it would be prudent for someone to be working in the back ground 
to refine our processing (using 1 liter batches) to get the chemistry 
right so we pass the test every time. 

These suggestions may be way out of whack if we have tested and are sure 
we are passing the ASTM quality test. Perhaps we need to pony up the 
cash to just go ahead and do that test after we get back on-line and are 
satisfied we are back to our standard production, then correlate the 
results with the ASTM grade stuff.

Thoughts from anyone?

Felix
