Distillation. The heavy duty gas turbine is not sensitive to the distillation characteristics of the fuel per se. Extremely volatile fuels such as naphthas require the use of a start-up fuel (light distillate) due to the low temperature at which they vaporize, giving the possibility of combustible vapors in the fuel lines. Very high end-point fuels, approximately 1000(Degree)F (538(Degree)C), can have excessive traces of vanadium which have distilled over. For this reason pure distillate usually would have a maximum end point specification. (This is also prevented by setting a maximum vanadium level.)
Distillation and Evap Area 1. Mechanical is about 98% complete. Complete small bore piping where needed. 2. Electrical is behind Mechanical installing instruments and wiring.
Distillation. As referenced in this booklet, distillation is a technique used to purify water by removal of inorganic contaminants such as salts through heating solution and condensing the steam. The resultant distilled water has a reduced concentration. Distillation is not effective in removing pesticides and volatile organic contaminants such as chloroform and benzene. EXPOSURE: Contact with an agent through inhalation, ingestion, or touching. For example, exposure to radon is primarily through inhalation; exposure to lead is primarily through ingestion. FILTRATION: Purification of water by removing un-dissolved solids or sediment passing the water through a filter or sieve. Filtration does not remove dissolved salts or organic contaminants. LEVEL: Another term for concentration; also, the amount of a substance in a given volume of air, liquid or solid. LITER: Metric unit of volume equivalent to 1.057 quarts of liquid. One gallon is equivalent to about 4 liters. MILLIGRAM: A unit of weight. There are 1,000 milligrams in one gram and about 28 grams in one ounce.
Distillation. ASSUMPTIONS: - Strips the ethanol from the beer and concentrates to 188 proof. - Production: 199+ proof fuel grade ethanol vapor - Assume emissions are 100% VOM, no PM/PM10 NEEDED INFORMATION: - Is there a scrubber for distillation process? Where is the exhaust routed (i.e., process scrubber, boiler (co-gen), T.O., other?) - What is the uncontrolled VOM emissions rate and VOM control efficiency for the scrubber?

Distillation. The fermented wash, then, would be taken to Distillation House. The distillation unit mainly consists of Wash Boiling Column containing stripping plates and Rectification Column containing about 50 stripping plates. Before feeding to the boiling column the fermented wash would be passed through beer heater and heat exchangers where the final temperature rises to about 850 C to 900 C. Fermented wash would be fed to the wash boiling column from its top and open steam would be introduced from its bottom. While the wash trickles from the top, alcohol vapours get recovered along with rising steam. The alcohol vapours, analyzed from this wash boiling column, containing 40% to 45% of v/v of alcohol would then be fed to rectification column at its bottom. Here, in this column, alcohol rectification from 45% to 95% would take place. The product i.e. 95% alcohol would be drawn from the top of rectification column where temperature would be about 780C, which is boiling point of rectified spirit. Thereafter, the alcohol would be cooled and stored in daily receiving tanks. Condensers and refluxes would be provided to each column for proper concentration and condensation. About one beer heater and one condenser are provided for the boiling column, whereas two condensers and one bear heater are provided to the rectification column. The daily product manufactured would be transferred to spirit storage warehouse.
