Step 4: Still Operation

After you have a still, operation depends on what type of still are using.

For all stills, basic operation is to:
1. Heat the substance so that the substance produces vapor.
2. The initial vapor that comes out (Foreshots) at 64.7 °C or around there will be Methanol. Although an alcohol, in large amounts it is poisonous and can cause blindness. You should discard the appropriate amount which can be found on the internet. If you are running a pot still, you will throw out alot more than a fractionating still or compound still.
3. The next vapor that comes out when the temperature is or near 78.4 °C will be the Ethanol. However, the ethanol can be separated into 3 stages.

All contain ethanol but the heads and tails are contaminated with other substances while the heart will be nearly pure ethanol.
You can choose to have the heads and tail in your drink but will taste bad. Save them and distill it again.
If you are making biofuel, just save it all. It can be used.

When the temperature nears 100, you should stop for all you will get at that point is water.

Under the carboy paragraph you've carboy misspelled as carbon
I kept thinking that I'd read it's legal to brew for personal use, not for sale. Basically, you can't go into business.
Last time I checked, it was still legal in the US to distill up to 100 gallons per year for PERSONAL consumption which includes use as a biofuel (although you will need a very low sugar content in the solution for biofuel). You may NOT sell it NOR transport it without a license.
Hi ,<br>Can any one help me out in some calculation work its really very urgent , please help me out ..... i need to consume 1932.3kg/hr of CO2 with the help of Algae in a pond (water) for example Raceway pond , so i need to know the specific area to construct that pond and its sizing and dimension (length,etc) and the quantity of water needed and amount of algae used so that it easily consumes the mentioned amount of CO2 rate per hour..... please help me out soon you can also drop your suggestion and questions if any my email id is : sudhirmalik2011@gmail.com ....i will be waiting for your reply soon and i'll be highly thankful to you, if someone can help please do tell me its very urgent....<br><br>Thank you
use sherry yeast , it yields highest % of alcohol, if it is added to a normal sugar water base.
The problem here is one of definition. Ethanol = ethyl alcohol and methanol = methyl alcohol. Alcohol is a chemical term for a group of substances of which methanol and ethanol are both a part. Because ethanol is the alcohol that isn't poisonous to humans, it's what most people think of when they hear the world &quot;alcohol&quot;.<br />
64.7 &deg;C is the boiling point of methanol and is poisonous in rather small amounts such as 3 ml. at 10 ml causes blindness.<br/><br/>ethanol has a boiling point of 78.4 &deg;C<br/><br/>When distilling fruit mass it is recommended to boil it slowly to 80&deg;C and keep it at that<br/>If temperature was higher the distillate wouldn't contain as much flavour.<br/>If distilling that way you should throw away the head (its about 1% of distillate)<br/>(fruit distillates yeld about 15 % of mass) , keep the middle and save the tail.<br/>Then you mix tail with water (50-50)and distill it again if you want it drinkable.<br/><br/>cybercorfu plx be more comprehensive in your posts ; <br/>&quot;ethanol=alcohol methanol=toxic&quot; &lt;--not equal<br/><br/>
I'm impressed! you sound like you know what yer doin. maybe you can answer a couple of questions for me. first, whats an " auto-siphon" and where can i git one? second, can you add more sugar and yeast and re-rack it again?
Ok, well here is the thing. An auto-siphon basically allows you to siphon without creating a suction with your mouth. I would highly recommend it and can be purchased from really any home brew store. As for the add more sugar and yeast re-racking, well there it can depend. I am not real sure what you are asking, but if you mean a solution that you already fermented sugars in, aka already has an alcohol content then its a yes but only to a certain degree. Basically, certain yeast are only capable of fermenting to a certain percent then they die from alcohol as it messes with the stability of the yeast. the typical yeast does around 8-13 percent. if you get champagne yeast, it can prob do up to 18% and some mixtures (with yeast, yeast hulls, and other nutrients) can prob do up to 21 or 22%. However, i wouldn't recommend really anything above 18 cause it really isn't all that good tasting. You get alot of fusal and other weird tastes. As for figuring out how much sugar to add to how much water, I would suggest you by a hydrometer, which is a floating weight with a scale on it that measures specific gravity. the specific gravity of water is 1 and as you add more sugar, it goes beyond 1 and when it is fermented all the way, the meter should be lighter than 1. I think it was .999. There is a certain ratio of sugar to alcohol conversion and most of these hydrometers have a thing on it as well that will tell you. Hope that answered your questions.
fer anybody what cares, alcohols vaporize at specific temperatures. here they is, Acetone-134 F, Methanol-147 F, Ethyl Acetate-171 F, ETHANOL-172 F, 2-Propanol-180 F, 1-Propanol-207 F, Water-212 F, Amyl Alcohol-280 F, Furfurol-322 F. hope this helps somebody!
Not Methanol my friend but rather ethanol big diference... Boiling point <br/>78.4 &deg;C, 352 K, 173 &deg;F of ethanol=alcohol methanol=toxic<br/><a rel="nofollow" href="http://en.wikipedia.org/wiki/Methanol">http://en.wikipedia.org/wiki/Methanol</a><br/>
Got a little confused on the spelling.<br/><br/>Mash!=Mass<br/>Carboy!=Carbon<br/>Healthy!=Healthily <br/>
No, Mash is not a misspelling, you apparently don't know beverage fermentation terminology. A mash is the combination of fermentable liquids and the yeast. Same again with Carboy, a carboy is a large glass container, one of those 5 gallon jugs that hold water for water dispensers. They are commonly used in hobby fermentation, both wine and beer making.
I know, he spelt mash as mass carboy as carbon, etc
O really? Meh it must have been the auto spell checker.
Is there anything else readers of this Instructable would like? I wrote this a while ago and there is always more to be added. However, I am only interesting in investing time if there are specific things people are looking for. Merci.
This is more of a science lesson than an instructable. It would be more useful to see pictures/description of your (not you're) own still. How can I make one from material readily available from a hardware store?
You can make it from hardware store supplies. But as i said, i have not made one for it really is illegal for the purpose of what this instructable. I am considering obtaining a fuel permit to make E85. If I do, i will post pictures of what i made. But honestly, I am also kind of reluctant to post the ones I have designed for it took weeks to develop them. Many of them are a bit unusual but theoretically very effective. Additionally, there are many factors that will determine the viability of a still. material you use, length of parts, width, surface area etc. There are like atleast 15 different formulas that must be used. The information here, is really like everything you need to know except the making of a still. The images that are attached to this, is really all u need. replace the lab glassware parts for parts that serve the same purpose.
You mean like kettles and copper pipe? I agree.
Aww, what a pity such a low score despite all the work. Very well, I will include a plan to make your own still from common hardware store goods. Look for it in the following days.
one of the bold things at the top wasn't bold like the others and in the 2nd to last paragraph it says "are dificult to make and require years" years of what?
