  • How do you dry/clean your BIO

    After you get to the end of the reaction how do you guys dry your bio - looking to see what everyone else is doing.

    Currently i bubble dry for a few days until the meth smell stops, then water wash twice then dry for a day.

    Whats everyone else doing ?

    While I have only started making large batches I have based my "procedure" on what I have learned from a few members I have met and lots of reaading here.

    I started to bubble out the Methanol then stupidly left the bubbler in while adding water to the first wash. NONO.
    so I'll be doing some similar to you in bubble for a day to get rid of the Methanol.

    Gentle Mist wash for the first wash as this seems to be the the safest first wash.
    bubble wash with water for the next wash and drain, then wash again with bubble for another day. drain then bubble dry for 24 hours.

      I do a two stage reaction, and throw in 1% water at the end, drain after a day, then bubble wash for a couple of days until no metho smell, drain off again. Then store in 44gal drums for 6 months to age. I used to water wash, but im getting i better results doing it this way.

        Funny when I started out using fat to make bio I only bubble washed with no water at all Used to think adding water just didnt seem right.
        I now do 2 stage no titration with 5-7% in processor wash with 150L/min pump with all the glyc added back in approx 32L send to cone tank settle remove glyc and do aggressive water wash using 20-60L water do soap titration and if around 30-50ppm will dry for 4-6 hrs in midday sun using nozzle fan spray and aggressive air bubble, works great can do 160L bio with 20-60L water and quantified low soap. Store in 44gal drums on their sides with 10-15 degree back slope about 4-6 weeks then tap off using only gravity feed beautiful crystal clear single malt whiskey.

          SO Gilfish, if you add all the glycerol back in then add 7% water by volume (is that volume of the BIO or BIO plus GLyc ?)

          Presumably pump mix for a while, (1/2 hour ?)

          Drain Glycerol - is this stuff OK to use as the prewash for the next batches ? or is it dead and buried at ths stage ?

            MIchael,i have found that the more methanol i extract the moire aggresive my washes can be.

            My lat couple i have had the garden host on flat out with a a very aggresive spray setting - no emulsion and i added this with the bubble still going flatout

              Re: How do you dry/clean your BIO

              Hi craig I have not found the volumes of glyc or 5-7% water to be very critical.
              I do a gly pretreat on 160-165L of oil this is mainly to remove water.Then this will require 30-32L methanol in two stages that will be a near full processor for me, I add 5-7%hot water of oil volume(160L) as post wash.
              The glycerol is as much as i can fit in remember the second stage meth/glys is still in and add back the glys i used for for the pretreat it is a lot thicker as most of the meth has gone I only need to pump for 5-10mins as my pump turns over the entire volume approx every 90secons. I save the first stage glys 28L as a pretreat for water removal on the next batch as my oil has free water in it.
              I think the best benefit for me is the second stage catalyst calculation done from % conversion I dont save much catalyst say 5-10% but the resulting soap after postwash are very small not enough to cause an emulsion. I am going out on a limb here and assume that it is because you get much closer to the ester end of the conversion being nearly 100% and that the soap scale is exponential like the richter, a small change has a massive effect.

                I'm probably the laziest bio maker here. I simply bubble for 7 days and store for a month or so befor using. Works a treat and saves water and my time. :-)

                    I am with Mav and Cade,, Water is such a massive overkill, mess, work and waste of the precious stuff... I do a little more than Mav by distilling the methanol from the bio before bubbling for a day... Always check it after wards for soaps and drum to store or for immediate use if needed...

                    My 80 has done 100,000kms on this and loves it....

                    I shudder everytime I remember all the Bio I made in the early days washing with water, I Bubbled, I sprayed, I sprayed and bubbled, I added heat I took it away FFS Don't even bother with GL just do as mav does chuck a bubbler under it and leave it for a week....

                        Re: How do you dry/clean your BIO

                        I hear you guys and agree with you, when I started out, for 2 years or so all I did was bubble air through the bio, would read how people were putting hundreds of litres water through and getting wet bio I could not see the sense in it.
                        Then I started doing quantitive soap titrations and realized my bio was still contaminated only small amounts , I never suffered white snot or any related breakdowns just 2 filters blocked but I believed I could do better.
                        Just recently since using the no-titration or 2 stage % conversion I consistently get soaps right after the reaction down at levels of 200ppm which requires only one or two 20L washes for a 160l batch of bio and it wont emulsify no matter how hard I try , also the bio clears overnight to perfect clarity. I spray dry it on a hot day to make sure of no water & if I start early morning I can have 160L usable bio with < 30ppm of soap no mono or di glycerides and no glycerol .
                        Water washing for me is quicker ,cleaner & less troubles than it has ever been, but each to their own I know you have been there and done that, just that weeks is too long for me and I am not in a position to have tank farms otherwise I would probably do it your way.

                        Kind regards andy

                          I am confused??? if you add water to Bio and do a shakem test and the water is clear why do you have to water wash your Bio?

                          I just settle for a few days (190lt) then bubble air wash for a few days till the meth smell goes then settle for a couple more days

                            Yes Matt, that's how both batches of fuel were washed, mine and KP's.

                            Murf, you use air to wash, thus no "drying" process required post wash. Those who water wash do so and then have to dry the bio, often done by bubbling air through the bio.

                            The one and only advantage I have experienced from water washing is that I can have fuel ready for the car in a minimun of 3 days, with air wash it takes a minimum of 7 days. I also find water washing very labour intensive (not to mention resource intensive), where as air wash is set and forget.
