Dewatering in a blend

Postby Bones » Wed Nov 10, 2010 5:59 pm

I have a good supplier of rapeseed oil who takes care as he knows what I use it for, his oil which on most occasions has the same qualities as new oil.

Most of the time I can just filter it without any dewatering/drying, it passes the HPT without issue and in it goes, that said theres always one or two cubies which fail and are put to one side.

My 205 litre drying barrel has a leak so out of use at the moment,

The oil is lightly water contaminated as it's stood for six months without separating, is it possible to use this as is in say a 50/50 blend with diesel?

TIA,

If it doesn't pass the HPT, I don't burn it. Its easy enough to get it dewatered to passing with 0 bubbles, so why not do it? Then blend.

Hello Sun,

yes, would normally de-water but as mentioned in my post the barrel has a leak, needs welding at this point I think.

It was just a thought after reading part of your water testing thread.

Is there some reason you just can't get another barrel?

Possible, yes....advisable, no. Blending with diesel does not solve water contamination problems.

My line of thought was the ppm would be greatly reduced by adding 50/50 diesel, I must admit i wasn't too keen on the idea.

>David,

I'll post a few pics when I get a chance, there maybe another solution to the leaks apart from welding.

Btw, are you the same chap from Oz with the Chevy pumps?

let it sit a few more days, out of sunlight, and siphon off the top, then retesting that sample. perhaps you can get a bit of it off the top of each cubie thats dry enough to pass for now. or try quik N' dri.

Mix with diesel then chill below 50°F 10°C. Most of the water will settle out with the sludge that falls to the bottom.

Cheers David, I always enjoyed reading your posts.

Three cubies that have now been standing for several months, water separating out on one or two.
