Hi everyone,
For those of you who are working on your process control for ethanol/methanol
or biodiesel production, I was wondering about something.
I hate to send anything to the land fill or scrap yard that I might be able to
use later and I'm sure you feel the same way. This philosophy
A temperature controller that would not upset because
of lightning or other power line disturbance and would
not lose its settings with power supply failure may
prove superior especially if less expensive.
Thus a bimetal strip may prove best in the long run.
I am in favor of data logging and

Nice discussion re most aspects.
Since CH4 may be 50 times more effective than CO2 as a
greenhouse gas it seems termite management might be
useful.

Thanks for the reply.
I have a couple of follow-up questions:
First, Is accuracy of your temperature set points (or other I/O) a critical
issue for controlling a process? Because, a PID or Smith compensator control
can give you far better control of your process than a bi-metallic

has a half-life in the atmoshpere of only a few years, (it oxidises to CO2)

termites? I can't even imagine what it means.

Hello John.
Keep in mind that you are addressing two different problems of the SVO.
Number one is the viscosity which is quite easily reduced by adding ordinary
diesel engine fuel. Number two is the boiling point which will not be
seriously affected if you add a liquid with a lower boiling range.

reliable as simple physical systems. As for the delta

Kirk,
Well, again, I don't think your logic is off base -- especially when it comes
to redundancy in control systems.
There are ways to approach each of the situations you described in your reply.
I worked as a control engineer for a few years and wrote computer logic

Right on!
I knew that I couldn't possibly be the first person to think of this. I just
didn't know where to look.
I will definitely keep you informed of any progress.
Thanks.

Hi folks,
I hear from more and more people who are mixing SVO into their B100
up to 50% and saying they have no problems with it.
When they've done half a million miles or so and still had no
problems, and a wide variety of diesels have done the same, then we
can believe them.

That is immaterial. Those emissions are essentially steady state.
Anthropogenic emissions are above and beyond natural emissions. The

Mark,
I think Ken and Bob did a good job addressing your response. So, I need not add
to it.
Even if Ken and Bob are wrong and global warming is junk science, you're
missing the point.
Most people associate Kyoto with global warming. However, you can't address
global warming without also

You are both correct for the most part, but, I would like to point out a few
things that you may want to consider, that make me disagree with parts of
