Vegetable Oil SVO WVO waste cooking oil as biofuel

David,
What was the temperature when you were dewatering?

My oil will pass a HPT no matter how hot I make it with no bubbles at all.

Making the WVO cool is what can make suspended water form when none was present before, see this chart: WVO Dissolved water and % saturation versus temperature Now that I compared 5 different water in oil measuring methods, I find the HPT is bad and will quit using it, since high FFA WVO can contain 1700 PPM (by sandy brae) and still pass the HPT with no bubbles. Plus the new cap. water meter I am using is much easier than a HPT, and gives quantitative numbers that don't rely upon your lighting, eyesight, type of pan, temp of pan, etc..

David,
What was the temperature when you were dewatering?

I don't bother measuring other than by feel but as a guess I'd say around 40-50oC.

The last couple of nights I put some oil into dry and didn't heat it at all. Nights here have been under 7oC and the days about 15 due to cloudy/ wet weather. Humidity would have to be very high due to everything being wet or recently soaked.

I have left the oil overnight and when i have come out in the morning, it warm due to the heat transfer from the pump and is also perfectly dry. I don't know if this takes 4 hours, 6 or more, but the oil is dry and that's all I'm worried about.
The pump is only small so costs me probably .50C a night to run.
This makes me enough fuel for 2 full tanks and at current prices would cost about $250 to buy dieso here.

Your work with the Meter is very interesting Sun and I have been following it although not really had the time to fully digest it. I'm planning on setting myself up with a device like this when I have the time to play around more.

I suspect your work with the meter was why Dana the Disease was trying so hard to shoot you down as he couldn't stand to see the one thing he held onto so dearly( and rammed down everyone's throats at every opportunity ) the HPT, to be proven faulty even though he kind of admitted then did a back flip on that every so often. At least that's what I think he did, with him it was hard to know what he was actually talking about.

I'll have to set myself up with one of these meters and test how effective my drying machine is. I might be horrified but at the end of the day, I have been doing what i have been doing for 3 years with this setup now and never had a problem so I can at least be content my final product isn't all bad.

So David, as I understand it, there are three possible explanations. I really need to see your setup to determine what is happening. The good news is that you should be able to verify the mechanism at play with the humidity sensor Sunwizard is using once you get it built.

Are you spraying the oil into the air? What is the oil pressure on the output of the pump's output?
