Getting off-topic a bit...

Any concerns about consistently drinking distilled water? I've heard it
can leach minerals from the body. A friend of mine uses a water
distiller so I'd like to know more.

Search the archives. It's in there.  Short version is: If you get your

As far as their claim of 90% distillation on 2 passes, well, I'll 
believe that when I see it.

Brewhaus says their only modifications are elimination of the chlorine 
release valve, and installation of a lower power heating element.  What 
they're describing is just the lower power version of the standard water 
distiller.  I have a feeling they didn't even change the thermal cutout 
to a lower temperature version.  They talk it up like there are all 
kinds of mods to it, but it looks like a standard water distiller to me.

My feeling is to give it a try and see what happens.  Operate it 
-=*OUTDOORS*=-, have a fire extinguisher handy, do the maths so you know 
what to expect, and give it a shot.

If it doesn't work then you'll only be out the ~$129 for the distiller, 
and if it doesn't burn up then you'll have a nice little water distiller.

I have one of these little distillers, and I use it every day for 
distilling water.  It's the only way I can make the lousy, chloramine 
laden St. Petersburg tap water fit to drink.

 Water distillation is mainly concerned with evaporation and then condensation water vapor evaporated, where as alcohol still need to selectively seperate low volatile etanol using heat ,as well as can condense selectively the ethanol and hence need 
column.Thus water distiller can be mainly smalltank type ,less condensation problem ,where as ethanol still is column.Hence tey need to be diffrent in design , eventhouh they all envolve similar process as you outlined. We here do like the design for small scale equipment for sustainable biofuel process 
developments.using air as coolant and then recover the energy for drying can be possible ,but yet taht type of noval distillation units need to evolved .You can try one taht can save the huge energy cost of ethanol as one need 5 Kg of steam for every 1 l of ethanol.

Re: [Biofuel] ethanol distillation

2005-11-23 Thread Ken Riznyk
Don't think so. The purpose of distilling alcohol is
usually to separate it from water. The boiling point
of alcohol is close to that of water so the
temperature of the vessel and cooling column is
critical. When water is distilled it is usually
separated from salts and other contaminants. The
temperature is not critical for that process.

 My question is about registering with the Federal gov't for legal
 distillation for fuel alcohol.  If the individual goes through all
 the proper paper procedures and obtains the distillation permit, what
 can one expect from the gov't after this?



 The only paperwork that is required for an Application and Permit For
Alcohol Fuel Producer (form 5110.74).  At present this form is not on
ATF's/TTB website for download.  Just a phone call to the national center
and they will put some in the mail to you.  I have never heard of anyone
having been turned down nor have I ever heard of anyone having a government
official show up to verify the permit.  There is not much to expect from the
government after the permit process.  You do need to file a report at the
end of the year stating how much alcohol you have produced.  I would guess
that they bounce this information against what number that you file for tax
credits.



 Are you only allowed to produce x amount of ethanol per year for
personal use?



 A small producers permit allows 50,000 proof gallons a year.  Personal or
otherwise.



 Will the individual be expected to pay highway taxes on their own alcohol
 produced?



 There are no highway taxes on ethanol.  Just tax credits.



 Does the gov't perform routine inspections on a person's personal still?



 I have never heard of a single inspection on a small producers permit.



 Also, what would make a good denaturant?



 Some acceptable denaturants are: gasoline, kerosene, deodorized kerosene,
rubber hydrocarbon solvent, methyl isobutyl and mixed isomers of
nitropropane.



 Final question to members-how does straight ethanol perform in fuel

 Great !  You can go to GM, Dodge and Ford and buy it off the showroom

Re: [biofuel] Ethanol distillation

2004-02-14 Thread [EMAIL PROTECTED]

Hi,

I was just wondering how much ethanol I could hope to product in one year
with a small still. I am hoping to get started this spring and I would
like to be able to product about 450 gallons of ethanol over the summer.
Using news paper as a feed stock, would this be a realistic goal?

Also, I have been looking around the web for more information about making
ethanol. I found a site for making hooch, but I think that fuel
ethanol is the same thing. From what I have read on that site you can make
ethanol from pure sugar in as little as 5 days, but need special yeast (or
yeast with other stuff added to feed the yeast). Would this be a good
choice for making fuel ethanol?

Thanks,
Al

Andy Thomson

Out of that list, I'd probably say pervaporation through an 
appropriate membrane
would be the most elegant, the most benign, and probably the cheapest 
to operate,
though maybe not the cheapest in capital equipment. For garage cookery
(i.e., developing nations), the molecular sieve is very reasonable, 
especially if you
could regenerate the sieve in a solar concentrator. 
Extractive/azeoptropic distillation
would be the hardest and nastiest, but maybe the cheapest.
