Let’s learn about the process background of biological fermentation for producing ethanol. Alcohol plays an important role in many fields, not only as an indispensable solvent and raw material in the chemical industry, but also for brewing various beverages and preparing distilled spirits. In the field of medicine, alcohol is often used for disinfection, preservation, and the production of medical reagents. In addition, alcohol can also serve as a renewable fuel and be used as a substitute for gasoline.

The raw materials for producing alcohol by biological fermentation mainly include starch, cellulose, and sugar crops. After pretreatment, these raw materials are metabolized by yeast to produce ethanol, which is then distilled and dehydrated to produce anhydrous ethanol. Finally, after denaturation treatment, fuel ethanol can be obtained. Fuel ethanol, as a renewable green energy source, can effectively alleviate the problem of oil shortage, achieve the conversion of agricultural resources and industrial energy, and reduce the emission of harmful substances in automobile exhaust, which is of great significance for protecting the ecological environment.
bioethanol production projects as a logical development of its engineering and contracting activities, using its long experience in sugar engineering as a major asset. The company has invested in the construction of biodiesel plants.
Ethanol production is one of the solutions that we has developed, where we are implementing new distillation technologies consisting of thermal coupling with multiple effects, either by integrating thermo-ejectors or by mechanical vapour recompression.
ethanol production plants
Since then, we has successfully built complete ethanol production plants using cereals, sugar beet and sugar cane, as well as cellulosic materials:
Autonomous ethanol plant and biorefineries using starch-type raw materials (maize, wheat, manioc, etc.)
By-product recovery units for starch-type biorefineries (wheat gluten, sugars, spent grains, energy, maize oil, etc.)
Distilleries using sugar raw materials (sugar, molasses, etc.)
Autonomous sugar cane ethanol plant with cogeneration
Extra Neutral Alcohol (ENA) production unit, as well as technical, pharmaceutical or spirits alcohol, etc.
Optimisation of process parameters in existing plants to improve viability, yields and cogeneration efficiency
Implementation of technologies for the production of second-generation ethanol.
offers a global approach to ethanol production, with the aim of improving the economic viability and environmental footprint of the entire plant:
CO2 scrubbing and recovery (for the soft drinks industry, dry ice production, etc.)
Vinasse concentration
Incineration of condensed molasses solubles (CMS)
Aerobic and anaerobic treatment of wastewater
Biogas production (methanisation – CNG)
handles all the facilities involved in bioethanol production, depending on the type of feedstock.
Our technology is also based on the use of an additional column to reduce the amount of wash water by increasing the amount of steam required.
