how do you get rid of waste water and glycerin?

how much of these waste products is generated?

did you factor in cost to heat oil up to 120 degrees to process for .65cents gal?

 

my oil is from restaurants here-free. normally my oil has Little or no water, but when it does, i boil it off on a electric range [ have a wind turbine so power cost isn't an issue]. as for the glycerin produced, for 20Gal of fuel made you get 3Gal of glycerin[or,40 Gal makes 6Gal of glycerin].once the glycerin is drained off i boil it in a contraption i made to reclaim most of my alcohol-then reuse later.then the leftover glycerin is used as fertilizer. as for heating the oil, as long as the oil is liquid at room temp you don't need to. the heating mostly is to speed up the reaction.

and for the post waayyy back there about gelling. in my first post i schould have been more clear. I've been experimenting with this for awhile and have found that if i remove more glycerin then normal[ at least a gal] anti gel seems to blend\work better, and have somewhat reliable results to about 5-15deg. but, to be safe i do start to blend around 32. until i have this perfected.

 

Im probably brewing up another batch this weekend. I lost the entire batch last time when the mist wash tank overfilled past the drain elbow (I still have no idea how) and drained all the bio onto the lawn.
How much alcohol do you reclaim? Ever tried doing a vacuum tank boil-off to get the water out of the oil? Im debating on if its worth getting a pump for this.

 

i have one question are any of you guys running the 80-100% in any northern cold and what are you doing about gelling both in your truck and while its being made

 

I did try the vacuum tank. it did work, but took forever with any real amount of water. however, it will remove dissolved water well-but still slow.

it's been fairly cold lately here,-5 on up. i am currently running a 50/50 mix. hasn't gelled with this mix.[ running to home depot right now to knock on wood- all of it ] i have blended less dino with the same temps with results ranging from gelled, to just ok, to good. but i feel that i am sloowly getting closer to 100% with each experiment. my lowest foolproof batch can currently go to the freezing mark

 

It would seem this takes some time & significant energy, not to mention a process that is still a work in progress. I have not seen any posts as to possilbe long term negative effects, either.
Obviously gelling in the cold would leave you immobile.
Is it worth it all?

 

I've run up to straight B99 in my truck with no ill effects and no loss in mileage or power. this was pump purchased bio, not homemade. Usually I run about 20-50% bio.

Methanol is the expensive part of making your own bio.

 

you have to think of it as a Hobie, with your ultimate goal of being self sufficient. by all means, don't let it scare you away from it. it is really quite simple one you get the hang of it

 

odd question.....is there some kind of federal tax deduction for making/using bio? just seems like there would considering all the energy tax deductions stuff out there. obviously, i just finished my taxes.

 

Just the other way around , if you make your own you need to keep track of what you burn on the road , and pay the tax in a timely manner .
The marketeers get a $1.00 discount as a blender .
The altenitives are not part of the power insiders so they do not get deals / paybacks / payoffs , ripoffs , I'll stop now .

 

my understanding is that you can make up to 400 gallons per quarter for your own use without having to do any tax stuff...

 

Isn't that wine & beer ?
I've read a bunch of government & other stuff trying to find out about the blenders credit [ for marketers only ] , and do not remember the make your own batch , 400 gal. issue , but the memory is not to be counted on .

 

great thread guys, anyone BUY their oil as opposed to getting it from a restaurant?

 

I think that if you go to Costco / Sams Club , it costs more that a gal. diesel , so recycle and save .
unless you could get a deal from a farmer / co-op , and get raw oil , not sure what that price would be , but then theres recycle again , save cost .

 

I have a been running B100 in my truck since September 2006. I have probably ran around 350 gallons of fuel with some 200 of those gallons being straight B100. I have 2006 Mega Cab, I think it uses the Common rail system.
No problems yet. But after reading this thread I might mix a little more #2 in with my bio to prevent the polymerization problem describe below.
