Ethanol Vs Dry-Mill

The product cost per unit under absorption costing is $15.00 and under variable costing are 10.60.

The purpose of this assessment was to characterize the pre-blended GPS (Grain Processing Corporation) alcohol, a mixture of 190/200 proof SDA-3A alcohols, produced from corn feedstocks (yellow No. 2 dent. corns) through enzymatic, fermentation, and distillation methods. For this purpose, the chemical and physical properties as show in the Certificate of Analysis (CoA) of the SDA-3AU were considered and their effects were investigated. This was performed by comparing the typical and acceptable limits of the weight percentage of total alcohol and methanol in the SDA-3AU against the current

Ethanol (CH3CH2OH) is a clear, colorless liquid. It is also known as ethyl alcohol, EtOH, and grain alcohol. Ethanol is widely produced by processing grains such as corn or starch and sugar crops. The grain is first milled, then fermented with yeast and different enzymes to turn the grain 's starches into alcohol(EPA). A distillation process then increases the ethanol concentrations, basically the same process a whiskey maker would use to make whiskey. Of course, law mandates that a denaturant is added, making the liquid unsafe for drinking. In the process, waste grain is produced and sold as farm animal feed. Bioethanol, can be made from many types of trees and grasses, but the procedure is much harder. The chemical formula of ethanol is the same whether it is made from starch and sugar-based feedstocks, such as corn grain (widely used in United States), sugar cane (Brazil), or from cellulosic feedstocks (such as wood chips or crop residues).

Alcohol fermentation results in the breakdown of complex sugars into simple ones. Stewart says that by wetting the grain, malting, begins “germination and prompts enzymes inside the grain to break down starch into sugar…” (Stewart, 31). Then it is just a matter of adding yeast to the malt to get the alcohol; however the barley mixture can be mixed with other grains to speed up the process. The result can be beer, whisky, or malt extracts; which oftentimes depends on the alcoholic product in mind.

Using manufacturing cost of $148.12 the product would have to sell for at least $207.

Generally ethanol is an alcohol found in alcoholic drinks. At 100% concentration, it is pure and a colourless liquid with a strong odour (due to weak Van der Wall forces :D. Ethanol is produced by the fermentation of carbohydrates in yeast cells and is used frequently as a solvent.

In the United States of America, corn ethanol is the main raw material we use to move our vehicles to accomplish our daily goals. Obviously, corn ethanol is presenting ethanol by corn. The biomass in the ethanol adds fermentation, a system that breaks down any chemicals or other substance in any liquid. Additionally, it is added distillation, the action of purifying the process of heating and cooling. This is how corn ethanol is made.

Ethyl Alcohol or Ethanol is the ingredient found in beer, and wine that causes drunkenness. Alcohol is formed when

Ethanol fuel is typically just made from plant biomass by pretreatment, fermentation, and distillation, which is very much the same way that beer and liquors are produced.

Ethanol (ethyl alcohol, grain alcohol) is a clear, colorless liquid with a characteristic, agreeable odor. In dilute aqueous solution, it has a somewhat sweet flavor, but in more concentrated solutions it has a burning taste. Ethanol, CH3CH2OH, is an alcohol, a group of chemical compounds whose molecules contain a hydroxyl group, –OH, bonded to a carbon atom. The word alcohol derives from Arabic al-kuhul, which denotes a fine powder of antimony used as an eye makeup. Alcohol originally referred to any fine powder, but medieval alchemists later applied the term to the refined products of distillation, and this led to the current usage. Ethanol melts at –114.1°C, boils at 78.5°C, and has a density of 0.789 g/mL at 20°C. Its low freezing point has made it useful as the fluid in thermometers for temperatures below 40°C, the freezing point of mercury, and for other low-temperature purposes, such as for antifreeze in automobile

Alcoholic beverages are the only consumable products in the U.S. that do not have nutrition labels. Consumers are being kept in the dark about serving size, alcoholic content, calories, carbohydrates, fats, protein, cholesterol and other nutrition information. Alcohol, specifically ethyl alcohol or ethanol, is produced by fermenting the starch or sugar in various fruits and grains. Alcoholic beverages produced by fermentation and distillation include beer that is usually about 4 to 6 % alcohol, wine that is usually 7 to 15% alcohol, and hard liquor which is about 45% alcohol.

Ethanol is industrially manufactured in two ways: the wet mill process and the dry mill process.

Biodiesels are one way new energy sources are developed. Biodiesel refers to a vegetable oil - or animal fat-based diesel fuel consisting of long-chain alkyl esters. Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, animal fat with an alcohol producing fatty acid esters).

Dry-mill, the more common and standardized of the two processes, utilizes the four basic processes of ethanol production, “clean corn is ground and mixed with water to form a mash… enzymes are added to convert starch to sugar… yeast is added to ferment… then distilled and dehydrated to create fuel-grade 99-percent ethanol” (Shapouri 2). The Wet-mill process commonly referred to as a “biorefinery” process approaches ethanol from a more atomic level. In Wet-mill ethanol production “grain must be separated into is components including starch, fiber, gluten, and germ” (Shapouri 2). Nevertheless Wet-mill production still uses the three processes above to create ethanol, the difference between Wet and Dry-mill is the quality of their byproduct. Through Dry-milling you avoid the complexity of multiply biochemical disseminations, which save energy and money through lower skill labor and lower tooling costs. However Wet-mill production makes more efficient use of mass and higher quality byproducts that will have greater market value. In the end the net cost of either method is variable, yet on the average the cost to produce a gallon of ethanol is less for Dry-milling than for Wet, yet when you consider the sale of extra byproducts this figure is reversed (SEE Table 2).

The feedstock of biomass which has different properties are different from many alternative energy sources. Thus, biomass can be converted to energy through many processes depending on kinds of materials used. There are some common biomass conversion processes:
