Description
Ethanol is obtained by the fermentation of sugarcane juice and intermediary products from the sugar manufacturing process.
Uses
• Fuel: used in internal combustion engines and as an additive for gasoline.
• Solvent: in many industrial segments, mainly paints and varnishes;
• Raw material: for the production of ethyl acetate, glycols, acetaldehyde, diethyl ether, neutral ethanol, quaternary ammonium, among others;
• Natural disinfectant: in the formulation of cleaning products;
• Fermentation process: used as substratum in the production of vinegars and acetic acid, due to its extremely low levels of fermentation inhibition.
Benefits
• High solubility in water and organic solvents;
• Clean and renewable source of energy.
Storage
• Large volumes: in carbon steel tanks with protection against atmospheric and other electrical discharges (grounded) and with special fire protection valves. The tanks should be protected by containment basins with capacity to receive the tank contents;
• Small volumes: in lined carbon steel, iron or stainless steel containers, at a safe distance from heat sources, with ventilation, with explosion-proof electrical installations and grounding systems.
Shelf-life
Up to 24 months.
Supply
• In bulk: Tank-trucks approved by Copersucar.
