Bioethanol
Refueling with alcohol
Alcohol/ethanol has been produced from a variety of biomass feedstocks for a number of years. The growth of ethanol is fueled by the desire to reduce dependence on fossil fuels and at the same time reduce carbon dioxide greenhouse gas emissions. Every industrialized nation is making an effort to utilize ethanol as a fuel.
Since the beginning of 2004 it has been possible to mix at least five per cent of bioethanol into fuel also in Germany – without having to fear negative consequences for the motors. Since 2007 the German biofuel quota act has been stipulating even a minimum addition of biofuels for petrol.
Efficient ethanol production is a prime concern.
Advanced biotechnology is applied to optimize yields in the hydrolysis and fermentation process. Following distillation, the whole stillage is separated by decanter centrifuges into wet grains and thin stillage. The thin stillage is concentrated into syrup by evaporation and this syrup is blended with the wet grains prior to thermal drying. The wet grains or the DDGS are utilized as protein enriched animal feed.
FLOTTWEG manufactures decanter centrifuges specially designed to meet the whole stillage separation requirements for the ethanol industry. These centrifuges are called FLOTTWEG DDGS DECANTERS. FLOTTWEG makes DDGS decanters in sizes that can handle feed rates associated with 5, 10, 15, and 20 MMGY of ethanol production per decanter giving the end user the largest selection available for true DDGS decanter technology.
FLOTTWEG DDGS DECANTER centrifuges have lower power utilization compared to conventional decanter designs and can save the end user 20 – 40% in operating power and 20 – 50% in lower installed horsepower.
