Complete Distillation and Chemical Processing: From Crude to Pure
Distillation separates, purifies, and concentrates. This campaign covers still construction, water purification, alcohol production, essential oil extraction, and basic chemical processing.

Application
Example

Separating liquids by temperature
Water: 212°F, Ethanol: 173°F

Refining complex mixtures
Alcohol from fermented wash
Steam distillation
Steam carries volatile compounds
Extracting essential oils
Lavender oil from flowers
Reflux
Vapor condenses and returns to boiler
Increasing purity
Higher-proof alcohol
Foreshots/heads
First distillate (low BP compounds)
Discard (contains methanol)
First 1-2% of run
Hearts
Middle distillate (desired product)
Collect (pure product)
Main alcohol collection
Tails
Late distillate (high BP compounds)
Discard or redistill
Last portion, harsh flavors

Simple pot still: 1) Boiler: large copper or stainless pot with sealed lid (5-20 gallon). 2) Lyne arm: copper tube from top of lid, angled downward. 3) Condenser: coiled copper tube inside bucket of cold water. 4) Collection vessel: jar or bottle at condenser outlet. 5) Seal all joints (flour paste, Teflon tape, or silicone). 6) Heat source: controlled flame or electric element. 7) Operation: heat wash slowly, vapor rises, travels through lyne arm, condenses in coil, drips out as distillate.

Yes (most)
Dissolved particles stay in boiler

Solar still (emergency water): 1) Dig hole 2-3 feet deep, 3 feet wide. 2) Place container in center of hole. 3) Surround container with wet vegetation, contaminated water, or moist soil. 4) Cover hole with clear plastic sheet. 5) Seal edges with soil/rocks. 6) Place small stone on plastic directly over container (creates low point). 7) Sun heats ground, moisture evaporates, condenses on plastic, drips into container. 8) Output: 1-3 pints per day (survival quantity). 9) Works with saltwater, contaminated water, or even urine.

Distillation procedure: 1) Fill still with fermented wash (no more than 2/3 full). 2) Heat slowly (patience — rushing causes puking/boil-over). 3) Discard foreshots (first 100ml per 5 gallons — contains methanol). 4) Collect heads (next 10% — harsh, set aside). 5) Collect hearts (main run — smooth, clean taste). 6) Stop collecting when temperature rises above 205°F or taste becomes harsh (tails). 7) Tails can be added back to next run for redistillation. 8) NEVER drink foreshots (methanol causes blindness and death).

Steam distillation: 1) Place plant material in still (packed loosely). 2) Add water below plant material (or inject steam from separate boiler). 3) Heat to produce steam. 4) Steam passes through plant material, carrying volatile oils. 5) Steam + oil vapor travels to condenser. 6) Condensed liquid collects in separator (oil floats on water). 7) Skim or drain off essential oil. 8) Remaining water = hydrosol (floral water — useful product itself).

Reference Card
Discard foreshots always (first distillate contains methanol — it causes blindness and death). 2. Low and slow (rushing distillation causes boil-over and poor separation — patience = quality). 3. Copper is ideal (copper catalyzes sulfur removal — copper stills produce cleaner spirits). 4. Solar stills need no fuel (sun + plastic + hole = pure water from anything — essential survival skill). 5. Steam carries oil (essential oils ride steam out of plant material — no solvents needed). 6. Oil floats on water (after condensing, essential oil separates naturally — skim off the top). 7. Temperature tells the story (monitor still temperature — it reveals what's coming out at each stage). 8. Charcoal filters everything (activated charcoal removes chemicals, odors, and toxins from water and air).
