    Re: washing with heat

    You are right. He's not a chemist and a substantial amount of what he says is wrong. I stopped reading his posts years ago.

  5. Re: My Ambient/ Room temperature Biodiesel Production

    Any calcium or magnesium salts of the fatty acids would be, as you have correctly noted, insoluble, and so they'd mostly drop out with the glycerol phase (they do have residual solubility in the...

    Re: FFA good or bad?

    I asked this question myself when I first considered using WVO. Most FFAs have a pKa around 4.5 apparently, which makes them about as acidic as vinegar (which makes sense as FFAs would all be...

    Re: Is this the best heat exchanger ever?

    Thanks for the tip. At $371 AUD they certainly arent cheap, not to mention all the buggerising around with fitting them. I think I'll proceed with the other setup for now....

    Is this the best heat exchanger ever?

    I haven't yet got my fuel heating system set up the way I want it, as I'm still waiting on some motorised ball valves to arrive. In the meantime, yesterday I was talking to my mechanic about it, and...
  9. Re: My Ambient/ Room temperature Biodiesel Production

    How much do you want to bet?

    If you knew any chemistry at all, you'd understand that the whole point of my method is that the vast excess of base swamps any residual FFA acidity. As you have no...

    Re: How do I plumb in a heat exchanger?

    I think I just found a really good heat exchanger that will blow anything else out of the water.

    This is off an M-series X5. It's used to heat the dino for more fuel efficiency. It's an...

    Re: WVO Upflow Design ok?

    Had a good chat with the guy in the filter place in Welshpool this week. Seemed to know his stuff. I was buying replacement elements for my Delphi filter. He told me they were 10 Ám which was...

    Re: washing with heat

    Luckily for you I am a Chemist, unlike anyone else on this forum.

    Just heating the brew to remove the MeOH won't work - it will probably form an azeotrope (most alcohols do), but in any case the...

    Re: How do I plumb in a heat exchanger?

    No those sizes should be OK, particularly taking into account the viscosity reduction the extra heat will supply. This will be upstream of the other HE. The thing I like about it is that's nice and...

    Re: How do I plumb in a heat exchanger?

    It's for VO, because the first one (on the car when I got it), is for hot water. So the oil never gets hotter than 55 degrees, which is kind of OK, but it's a bit smokey when driving around town. I...

    Re: How do I plumb in a heat exchanger?

    Gotcha! I've finally worked the plumbing out - I didn't realise the heater loop as a completely different circuit from the coolant circuit - and in fact that's what the current HE is running off....

    Re: How do I plumb in a heat exchanger?

    Yes that's what I like about them too. And the oil is already coming in at 55 degrees, which is running fine in the car, I just want to reduce the thermal inertia of the system by fitting it upstream...

    Re: How do I plumb in a heat exchanger?

    The Frantz is a necessary part of my setup. Although it is (apparently) prone to cavitation it pulls out very fine particles and is much more use than an inline filter (every one I have seen has...

    How do I plumb in a heat exchanger?

    Following on from the other thread, my SVO is running well in my 1HDT motor, but because the HE was installed by the previous owner for showers, it's not the right unit, or in the right place for...

    Re: Pre Heating WVO before injector pump

    Change of plan - I've decided I'm going to install a second HE, before the CAV filter. What's the story with the plumbing? The coolant ports on the Helton unit are smaller than the other heater hoses...
  23. Re: My Ambient/ Room temperature Biodiesel Production

    FYI the other advantage of my method is that because of the very high catalyst concentration, a stirrer is not required. An el cheapo pool pump from EBay (set to recirculate) provides sufficient...
  24. Re: My Ambient/ Room temperature Biodiesel Production

    Did you? You didn't mention that above - you were talking about 23-47 degrees.

    So now all the threads on this site that talk about heaters can be removed and...
  25. Re: My Ambient/ Room temperature Biodiesel Production

    FYI my method can be used in the middle of winter with the temp at 8 degrees. The biggest problem I have is with the recirculating pump that does the mixing - at that temp it struggles with the...
