What is hydrous ethanol?
Hydrous ethanol, popularly called alcohol, is a biofuel sold at gas stations and used in vehicles, fueling thousands of cars every day. The production process of hydrous and anhydrous ethanol can be carried out in different ways, with different raw materials. In Brazil, the main source is sugarcane.
Do cars in Brazil run on pure ethanol?
Most automobiles in Brazil run either on hydrous alcohol (E100) or on gasohol (E25 blend), as the mixture of 25% anhydrous ethanol with gasoline is mandatory in the entire country. Since 2003, dual-fuel ethanol flex vehicles that run on any proportion of hydrous ethanol and gasoline have been gaining popularity.
How much ethanol does Brazil use?
Brazil’s total 2019 ethanol production is estimated at 34.45 billion liters, an increase of four percent compared to the revised figure for 2018. Total domestic demand for ethanol (fuel and other uses) for calendar year 2019 is estimated at 33.93 billion liters.
How does Brazil transport ethanol?
In Brazil, around 90% of ethanol is transported by road, and the remaining 10% is transferred by pipelines or railroad, used as “return freight”. Up to now pipelines are not exclusive for ethanol. From the total 7,100 km of pipelines for liquid fuels in the country, around 900 km are used to transfer ethanol.
What is the difference between anhydrous and hydrous ethanol?
The difference lies in its water content. The water content of anhydrous ethanol is approximately 0.5%, compared to 5% for hydrous ethanol. Anhydrous ethanol is used as an additive in gasoline, whereas hydrous ethanol is used in its pure form, in vehicles that have been duly adapted for this fuel.
Is anhydrous ethanol denatured?
Ethanol, anhydrous (85%): This product is 95% (190 proof) ethanol and has not been denatured. It is designated as Molecular Biology grade.
What percentage of Brazil cars run on ethanol?
Brazil today is home to the world’s largest fleet of cars that use ethanol derived from sugarcane as an alternative fuel to fossil fuel based petroleum. Twenty-seven million cars, 73% of the total, can use a mix of ethanol and gasoline.
What cars can use 100% ethanol?
Pure ethanol – 100% ethanol or E100 – could theoretically be used to power cars, but generally isn’t, for numerous reasons:
- Ethanol is bad for cold-starting, because it doesn’t burn as quickly as gasoline.
- There are no passenger cars designed to take E100 (but some racing cars are) so it could damage your car engine.
What crop does Brazil use to produce ethanol?
sugarcane
Unlike the United States, the vast majority of Brazilian ethanol is made from sugarcane. The country has roughly 350 sugarcane ethanol plants, largely concentrated along the coast. In 2019, the country produced 37.38 billion liters of ethanol, 96 percent of which came from sugarcane.
How has ethanol been useful to the Brazilians?
It enabled Brazil to gradually augment its production and blend. With a mandatory blending of 27 per cent ethanol with gasoline, in 2019 alone Brazil saved about 0.5 million barrels per day of gasoline with a savings of $13 billion in imports.
How is anhydrous ethanol made?
Production of anhydrous ethanol in large scale has been made by extractive distillation using conventional solvents like ethylene-glycol. In the present paper, extractive distillation process is studied to obtain pure ethanol using ethylene-glycol and tetraethylene-glycol as solvents.
What kind of ethanol is used in Brazil?
In Brazil, ethanol is available in gas stations in two different fuels types: the hydrous ethanol and the anhydrous ethanol. The hydrous ethanol (94% ethanol, 6% water) is used directly in E100 vehicles and also in flex fuel vehicles.
What kind of fuel is hydrous ethanol used for?
The hydrous ethanol (94% ethanol, 6% water) is used directly in E100 vehicles and also in flex fuel vehicles. The anhydrous ethanol is blended with gasoline to make the E (20–27) fuel domestically known as C gasoline, with the blending content defined by the government depending on the ethanol availability and market conditions.
When did Volkswagen start using ethanol in Brazil?
In March 2003 Volkswagen launched in the Brazilian market the Gol 1.6 Total Flex, the first commercial flexible fuel vehicle capable of running on any blend of gasoline and ethanol.
What kind of gas does a Brazilian car run on?
The Brazilian car manufacturing industry developed flexible-fuel vehicles that can run on any proportion of gasoline ( E20-E25 blend) and hydrous ethanol ( E100 ).
