HMPEs dropping out of clear bio.

I take it that your "incomplete conversion" resulted in a slight failure on...

Cold weather additives

Without wishing to brown-nose here, I'm with Jamesrl. I am looking to make fuel that doesn't need cold weather additives. However, unlike James, I shall be trying to freeze/settle out the HMPEs rather than filter.

yes interesting stuff, urea, main component of, and extracted from urine? so once bio is finished we just take a leak in it and then just filter out HMPE's and drain off urea?

When to stop washing?
Published (2009-12-31 18:46:00)
If you want a clear Shake-em-up you should continue to mist wash until the water coming out is the same going in. Try making the mist finer. This will generate a better washing action with smaller water droplets. Looks like your droplets maybe a bit on the large side considering the amount of water you have used. Mind you...you could just have really soapy bio in which case you'll need plenty of water anyway. Nige

Pretty normal for elect supplier to bond earth and neutral together at your cutout.

HC II ... Generally with WBD I settle for an hour or two which I think may be longer than some people but with 5%PW I usually settle overnight. The results I've had on the last three batches were: 1) WBD, stopped well short of stoichiometric, no washing, a couple of hours settling, long final demeth, overnight bubbling = HMPE dropping out at recent ambient temps. 2) WBD, stopped well short of stoichiometric + 5%PW, settle overnight, long...

Hi my inline heater is built with these elements from mesilus just put the earth to the body of your heater or on the boss and it will work fine no tripping of your rcd

If the oil had overheated for a long time there would have been some breakdown resulting in more FFAs, which obviously isnt the case if it titrates at
3. In any case 105C is still well below frying temperature.

Depending on what you make you bio from will affect the cloud point of the bio (the point at which precipitates form). Rapeseed and sunflower tend to
give bio with a lower cloud point than soya or palm.
The usual way to check is to leave a jamjar full of bio outside at a convienient location (ideally one that can be seen from inside) so you can easily
check whether your bio is waxing or ...

Sounds like the element is down to earth. Not a good idea to get near the processor if you disconnect the earth bonding.
Have you tried checking resistance between the boss of the element and one of the terminals at a time?
Fixing an earth terminal to whatever the element screws into should not be hard, an earth tag for a large (50sq.mm or similar) armoured cable gland
may fit ...

What is the WVO like that you use as feedstock.
Is it liquid or solid at the sort of temps we are experiencing at the moment.
Can't say i've ever experienced the problems you're having.
My oil is mostly soy/rapeseed, always titrates below 3, usually 1.5-2.

Well done!!
Assuming you've now added the prewash water, you need to run your pump for about 15mins to give it a good "wash".
Then switch off the pump and settle. You should see most of the glycerol settling within 15mins, so a days a bit over the top.
You can do the mist wash thing, but most seem to think this "old hat".
Personally, I do just as you have, then bubble ...

I asked the very same question about 6 months ago. It seems that this is the way everybody does it, but be as far from your garage door as possible.

Unlucky Mark. I hope it breaks soon.
I take it that your oil is high titrating.

Worth filtering cold in this weather to pull out the HMPEs before they hit your in-car filter (unless, of course, you have a heated in-car filter!)
That said it'd be a shame to clog a 1 micron quickly with HMPEs.
TAM105 should be fine for the job, pushing through the filter rather than pulling.
