What is the problem with ethanol?
The long-term effects of using ethanol fuel can be significant, and should not be taken lightly. Ethanol fuel can cause storage problems, water problems, and engine problems over time due to the corrosive nature of the fuel. It can degrade rubber and plastic parts in engines and fuel lines, leading to costly repairs.
Ethanol reacts naturally with oxygen in the air to form acidic compounds which lead to corrosion of fuel system components and engine wear. With the presence of both water and ethanol, corrosion is accelerated in all metal types. Aluminum engine and fuel system parts are very susceptible to ethanol corrosion.
Higher-ethanol blends still produce significant levels of air pollution, reduce fuel efficiency, jack up corn and other food prices, and have been treated with skepticism by some car manufacturers for the damage they do to engines. Growing corn to run our cars was a bad idea 10 years ago.
Chronic ingestion of ethanol may cause liver cirrhosis, affect the nervous system and affect the glands in humans. Ethanol may cause mutations (genetic changes). Ethanol is rapidly oxidised by the body to carbon dioxide and water, with no cumulative effect.
Ethanol: Contains significantly less energy per gallon than gasoline. Is hygroscopic, meaning it absorbs water out of the air, which means it can damage engines due to excess water content if not handled carefully.
The research, which was funded in part by the National Wildlife Federation and U.S. Department of Energy, found that ethanol is likely at least 24% more carbon-intensive than gasoline due to emissions resulting from land use changes to grow corn, along with processing and combustion.
Many cars and light trucks (a class containing minivans, SUVs and pickup trucks) are designed to be flexible-fuel vehicles using ethanol blends up to 85% (E85) in North America and Europe, and up to 100% (E100) in Brazil.
Ethanol produced from grain is viewed by many as a way to reduce energy imports, levels of carbon monoxide in the air, and surplus grain stocks. Federal and State governments helped to establish the fuel ethanol industry by providing direct payments, tax exemptions, and loan guarantees.
Ethanol can lead to malnutrition, and can exert a direct toxicological effect due to its interference with hepatic metabolism and immunological functions. A causal effect has been observed between alcohol and various cancers.
The distinction between alcohol and ethanol is pretty simple. Ethanol, or ethyl alcohol, is the only type of alcohol that you can drink without seriously harming yourself, and then only if it hasn't been denatured or doesn't contain toxic impurities.
Is Everclear ethanol alcohol?
The 190-proof variant of Everclear is 92.4% ethanol by weight and is thus produced at approximately the practical limit of distillation purity.
This is because ethanol is not an ordinary mixture, it's an azeotrope. Instead of boiling purely and separately at two different temperatures, its vapor will form a certain proportion. Steam from alcohol is 95.57 percent alcohol.
Using higher amounts of ethanol reduces fuel economy. There would have to be a large infrastructure change to provide ethanol refueling stations. Ethanol also absorbs water easily giving it a high tendency to corrode materials.
Ethanol has a higher octane number than gasoline, providing premium blending properties. Minimum octane number requirements for gasoline prevent engine knocking and ensure drivability. Lower-octane gasoline is blended with 10% ethanol to attain the standard 87 octane.
Natural gas one of the safest and cleanest fuels available. It emits less pollution than other fossil fuel sources. When natural gas is burned, it produces mostly carbon dioxide and water vapor -- the same substances emitted when humans exhale.
Some people may not like ethanol in their gasoline for a few reasons. Ethanol can potentially cause harm to certain types of engines, particularly older engines and small power equipment such as lawnmowers and chainsaws. Ethanol can attract moisture, which can lead to corrosion and other issues in fuel systems.
The Danger Of Harmful Emissions
Furthermore, burning corn ethanol in gasoline can release a known carcinogen, benzene, amongst other harmful air pollutants. These pollutants may trigger bronchitis, asthma, as well as a range of other respiratory problems.
The United States is the world's largest producer of ethanol, having produced over 15 billion gallons in 2021. Together, the United States and Brazil produce 82% of the world's ethanol.
E85 is typically cheaper per gallon than gasoline but slightly more expensive per mile. Performance. Drivers should notice no performance loss when using E85. In fact, some FFVs perform better—have more torque and horsepower—running on E85 than on regular gasoline.
In fact, nationwide availability of ethanol established back in the late 1970s was a key element in the success of flex-fuel vehicles, which now account for 85pc of all cars on the road in Brazil, and 83pc of all new light vehicle sales in 2022, data from Brazil vehicle association Anfavea says.
How do they turn corn into ethanol?
Dry-milling is a process that grinds corn into flour and ferments it into ethanol with co-products of distillers grains and carbon dioxide. Wet-mill plants primarily produce corn sweeteners, along with ethanol and several other co-products (such as corn oil and starch).
Texas is the leading consuming state of fuel ethanol in the United States.
Local carcinogenic effect of ethanol
This is explained by the fact that ethanol is a proven carcinogen and in addition, metabolite of ethanol (acetaldehyde) produced in the liver is highly carcinogenic, thus explaining both local (mouth, throat, esophageal cancers) as well as distant (skin, liver, breast) cancers.
Ales are generally around 4–5% ethanol while lagers generally contain 4.5–5.2% ethanol. Beer yeast generally cannot tolerate an environment with greater than about 10–11% ethanol (Wyeast Laboratories, 2006) and as the ethanol concentration in the environment rises the efficiency of fermentation declines.
