How To Flush A Biodiesel Dry Wash Exchange Resin Tower Using Methanol

[lalo1989cm]

is glycerin a byproduct of this?

[graydonblair]

@lalo1989cm You'll get some glycerin out of it when you flush the tower. This is because the resin does absorb some glycerin as it cleanses the Biodiesel.

[lalo1989cm]

@graydonblair Is it the same glycerin they use in medicine and food, though?

[graydonblair]

@lalo1989cm No. Very much crude glycerin comes from Biodiesel

[lalo1989cm]

@graydonblair you mean the type of glycerin they use on medicine and food comes from biodiesel?

I dont get it, was he making dark choclate or syrup

Leon is quite helpful and a wonderful very competent engineer .

[circusboy90210]

please explain the benefits of this process on top of using a centrifuge , and what glycerin will do to your injectors etc.. if not removed . people seem to think that svo is safe for their vehicle.

The process shown is just showing how to clean dry wash media. When enough finished Biodiesel is run through dry wash media, it begins to get plugged with soaps and glycerin. In order for the media to work again, it needs to be flushed with methanol to remove the contaminants.

Alpha Laval centrifuges can remove glycerin from Biodiesel, but not the Dieselcraft Style or the WVO Designs style. Their purpose is to remove particulate matter; they're simply acting like filters.

@UtahBiodiesel

Also, the centrifuge is used on the oil before it's made into Biodiesel. It can be used on the finished Biodiesel, but it's only filtering any particulates and won't remove any soap or glycerin. The dry wash media remove residual soap & glycerin from reacted Biodiesel; which is what this tower has been used for.

The video is just showing how to clean one out once it's exhausted.

@UtahBiodiesel what is the technical difference in the styles of centrifuges?? would it be the break point at which the fluid levels seperate because of their mass?? is the most essential thing then the width of the lip on the centrifuge?? or lateral depth of the bowl or both?

[UtahBiodiesel]

@circusboy90210

You know, I'm not really sure. But I do know that in the Alfa Laval ones they actually have spinning disks. I think there's a lot of science that goes into the really spendy units though. The WVO Design ones are pretty basic. I'd give a call to WVO Designs & visit with Leon. He's an engineer & the one who designed the one I carry.

Sorry, not a lot of help on it.

so i only have to buy one bag of thermax i wont have to buy another bag?

[graydonblair]

@russianstarwelder The thermax can be regenerated several times before it completely wears out. So eventually you'll have to replace the thermax, but you can usually flush quite a few times before it's completely worn out.

[UtahBiodiesel]

Yep. They do a great job.

[Drywash08]

These guys are awesome!

[UtahBiodiesel]

No, only when the resin quits removing the soap effectively during each wash. The methanol can be reused for more reactions to make bio.

Details on this are in the link on the right in the description.

do you have to run this flush after each time your dry a batch? what happens to the methanol? do you throw it out?
