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

Watch in high quality!

This video details the steps required to clean a typical Biodiesel Dry Wash Resin Tower that utilizes Ion Exchange Resin such as Purolite, Amberlite, or Thermax Ion Exchange Resin.

When Ion Exchange Resin is used to dry wash Biodiesel, occasionally it is required to flush and clean the resin beds. This video details the proper way to do this procedure.

Steps Required:
Flush the resin bed 5 times with Methanol
Test for soap and methanol purity
When done, drain methanol and allow to dry
Re-initiate resin (load Ion Exchange Resin Bed properly) and place back into service

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.

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?

@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.

[UtahBiodiesel]

Yep. They do a great job.

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

[graydonblair]

@lalo1989cm No. Very much crude glycerin comes from Biodiesel

[lalo1989cm]

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

[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]

is glycerin a byproduct of this?

[pray4theGay]

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

[circusboy90210]

Leon is quite helpful and a wonderful very competent engineer .
