Separation using high voltage works fast

Hello BD makers,


Tired to wait for separation of Glycerine!! try this.
Using 2.4kV for separation from biodiesel from glycerin less then 2 min. I have this HeNe Laser ballast to generate high voltage araound 2.4 kilo volt at 5mA, did some test on 200ml WVO batches mixed with METHOXIDE and blend for a minute after finished mixing immerse the cable (make sure the cables dont touch each other) in to the WVO and power on the high voltage, watch how the glycerine separation occur less then 2min. Very easy and simple.

Best regards,
Aaron

Re: Separation using high voltage works fast

is that AC od DC ?

and if DC , does it change the result by having positive or neg at the bottom of the tank instead of side by side

and where are your safety notes , we dont want some 11 year old plugging their 240 V in there du wee

Aaron,
Is this part of a scientific research project or your backyard processing?
I would be interested in reading the research paper, if available, or just the abstract.

another useful tool.

amazing

Hello ZeroEmissions,

Its DC ballast I tried at the bottom of the tank it works but slower i think because the glycerol collects at botten and is less conductive, side by side works better, BTW Its very safe to use, its only 5mA on 2400volt no harm but immerse the cables totally in the WVO so there will be no sparks (spark + methanol = bad)

Aaron

Hi Tony,

Its just backyard process, I dont have details on paper yet, There is videos going on youtube they call Electrostatic separation, I just found the videos thanks to geewizztoo.

Re: Separation using high voltage works fast

Sorry folks I have to clear this one its 0.5mA not 5mA. I didnt see the dot on the ballast.

Re: Separation using high voltage works fast

You can build very cheap and easy electrostatic electronic circuit from diodes and capacitors its called voltage multiplier direct from 240volt.
Later i post the details.

Re: Separation using high voltage works fast

DC output would be no good for this as it would cause electrode erosion and add metals to (chemically alter) the final product. AC and a pair of 306 stainless electrodes would be ideal to stop this. I'm assuming 50Hz is ok, but I'd rather go up to a high frequency to prevent electrolysis of the electrodes.

If it works with AC it would prove it's a electrostatic process, otherwise if it's DC that makes it work, it's electrolysis.

I love it. It's officially my next project/upgrade.

These videos appear to be related to separating biodiesel/water emulsions,not biodiesel from by-product.

Any relating to biodiesel process settling?

No they're not. Watch the video, it's primarily for settling glycerol from biodiesel. But the note at the bottom of the page says it can be used for breaking emulsions at the 4kV level. I fail to see how you came to that conclusion, its even wrtten in the text below the video.

BjBlaster

is that your genset inside the green doghouse ?

you must have air circulating _through_ the box or it will overheat



good dog..........

Re: Separation using high voltage works fast

I think this is a little off topic, but yes it is twin fan cooled using 2x 200mm fans and doesn't overheat. I will update the page with more pics and things at a later date.

Now on with the story... If this electrostatic method is so good, why isn't everyone doing it? Does it help in any way other than being faster? For example does it make sure complete reaction has occurred and no glycerin will drop out after it settles for a few months etc...It sounds great if it can make sure all of the reaction has completed.
