RE: compressor

We had been using either of two compressors at the site. Why would we need
another one?

I got a call from Karen today as she shopped for a compressor, but didn't
hear back.

If you got one, that's great.  If not, I have a small one I will bring to
the site to test.  It has to come home with me tho, because it is an
integral part of my remodel.

Let me know by phone or email.

Thanks,

p.s. Pete, the enforcer, will be upset, but I have been reading a lot about
vacuum water removal for oil of late and that may be the next chore for our
existing compressor.

What say you Greg R?

Sorry I have been out of touch. I've begun working (for pay) and have little
time for anything else.. Here is the task list from our meeting on Sunday.
If your name is on the list of tasks, please contact me so we can coordinate
your availability. If you are unable to complete a task assigned, let me
know.

Zan and I completed table top tests last week. We spent a total of around
8-10 hours carefully running specific tests to identify our problems. I will
send a separate email with those results. The findings from those tests are
as follows:

1. Our KOH on-site is good.
2. The reasons for the last three problem fuel batches have been found:
a) mayonnaise was caused by deficit of lye in a batch; incomplete lye =
incomplete reaction
b) incomplete reactions caused not enough methanol AND high amounts of water
in oil
3. We have confirmed the correct proportions to get good results on the
table top. This includes 7.78 as our base amount for lye; 22% methanol per
volume of oil
4. heat of reaction is not as critical as water content of oil
5. Ambient heat during the settling period after reaction is not critical.
6. water content in oil has been our CHIEF culprit since the weather cooled;
significantly less amounts of water have settled to bottom of our oil totes.
We MUST get this water out of the oil before reacting.

Here is the current plan:

1. Finish preparations this week for a test batch on Saturday
2. React a batch this Saturday. Heat and drain water from oil before-hand.
a) We're going to react 45.5 gallons of oil with 10 gallons of methanol
(this gives us 22% meth./oil)
b) we will not be doing a prewash
c) we need to ensure we are mixing methoxide slowly and thoroughly to
maximize the reaction.
3. Meet sometime to discuss attacking the water issue long-term.

(Names in parentheses are meeting attendees responsible for getting task
assigned)

Steps to prepare for this weekend:

Make new KOH solution - Tamar (Zac)
Purchase air compressor for 30 psi pump - Karen
Add mark on reactor site glass for 45.5 gallons/ 47.5 gallons (for water
injection level) - volunteer (Pete)
Check methoxide mixer capacity for 11 gallons - volunteer (Pete)
Fit reactor with valve for injecting water - Greg R. (Zac)
Finish 1st settle tote plumbing - Felix (Zac)
Finish wash/dryer plumping - Greg/Felix (Zac)
Add thermometer to reactor - Felix (Zac)
Test heating elements oil heater #2 - Zan (Zac)

- Felix indicated that he will install thermometer this Saturday.
- I tested the heating elements in both oil heaters #1 and #2. Both measured
a low resistance. Need to have Zan test voltage across them, but we are set
to heat oil in heater #1 for now.
- We need a way to measure and introduce our 5% prewash water into the
reactor. For this weekend, however, I recommend that we DONT do a prewash.
Let's let the reaction take as long as it can. We will reintroduce the
prewash after we've made some good fuel. It is not a critical step and may
be hurting us with cold ambient temperatures.
- Pete: We have pots on site and a hot plate. I checked Sunday afternoon
after you left.

Zac,
Since I have a hard time remembering things like photo-copying your notes, I
get to test my memory on items I was responsible for. Here goes:
*       I am primary for securing a small (~1 qt) pot for oil/water boiling
test
*       I am to send an e-mail out to get coop involvement to get/do:
o      Get an air compr to handle a 30 psi air pump
o      Ask Greg R to pick up thermometer from Felix and install?.. (not sure
about this one)
o      Finish valving at oil heaters inside Konex? (not sure about this one)
o      Get a 1" to 3/4" threaded fitting for water pre-wash into processor
o      Calibrate processor for a 45.5 gal line, tape it and label it
Are we saying we want all of these things done before next Sat?.. Just want
to make sure I properly request. Let me know if I mis-wrote something or
missed anything else I was responsible for.
Thanks.
