more chinese oil with water and gloopy fully converted to bio

[alifreddy]

got some thick gloopy oil from Chinese bought it without checking as I had a good result from last batch I had from another takeaway.

Filtered 60 litres through a 400 micron bucket filter drained off about 5 litres of water from bottom after heating. added 10 litres of glycerol with a bit of bio tied up in it made this gloopy creamy thick gunge that my processor couldn't pump so drained it off

waited till it changed to runny oil titrated at 2 and got a good result 10 litres of glyc and bright clear bio

Its good I can use even the worst types of oil for bio now

Let us know how you get on with it, I'm processing some thick cream from a Chinese place at the moment but I'm finding the bio it makes is clouding even though it's only getting down to 8C or so.

It also seems to form skins when sat, and foams a bit when aggressively pumped - however no soap to speak of on the soap test.

Runs in the car OK.

 I sometimes use oil from chinese so bad that it glues itself to the heater element and then the heater burns out and needs replacing. 
After experimenting I found that if I put the oil into a settling tank and put in 20 litres of glyc and then leave it for a couple of days I then drain off about 30 litres of brown sludge. It then processes as normal wvo.

[Tony]

Yeah I've had the same, nasty gunk on the element.  I've also done the glyc in with the worst of it for a few days, like you say it works a treat

[alifreddy]

got some more oil very black rapeseed from another Chinese. titrated at 6 before glyc washing heating and now gonna add 10litres of glyc to 50 litres of oil

[alifreddy]

I got the black oil to change to biodiesel. have some other black oil I tried using but the bio was still black it splits with water and only a small drop out on 27/3 test.

will try reprocessing with glycerol or what would u suggest

[willbuild]

if you processed for over a hour and it did't pass the 27\3 test then drain of the Glyn and add catalyst= to the fall out with 1 or 2 litres of meths and mix for at least an hour then re test. if no pass run another 30 Min's, then test again.
once you get a pass put back the glyc and do your 5 or 7 % water wash.
By removing the glyc it makes it easier for the last bit of oil to convert to bio.
you should find that once it passes it colour will get lighter

[alifreddy]

the fall out is about 1ml how much catalyst is that

[Jamesrl]

the fall out is about 1ml how much catalyst is that

The 1ml of drop out means 33% of the batch has not converted if you did a 3/27, 10% if you did a 10/90.

With that info you can work out how much lye/meth you need.

[alifreddy]

[willbuild]

looks like a 10/90 test, so 10%

you really shouldn't have to guess : (

[alifreddy]

that's a small Pyrex flask its a 27/3 test u were wrong. got it to change to a lighter colour added another 10 litres of glycerol and drained a little under 10 litres of black liquid then it changed to light after heating for a bit will test it tomorrow

[julianf]

that's a small Pyrex flask its a 27/3 test u were wrong.

Really, what's your game?

You posted the photo.  What was anyone meant to say?  Were they meant to guess what the photo was?  What it was showing? 

Why not just make it easy for people to help you?  Why couldnt you have told people what the photo was of, or even, when you asked this -

the fall out is about 1ml how much catalyst is that

...just have told people what they needed to know.  Are you just really lazy, or do you not understand??

[alifreddy]

I stated earlier " have some other black oil I tried using but the bio was still black it splits with water and only a small drop out on 27/3 test.


why are u getting upset
