Abstract:
The production of biofuels from grain have been strongly criticized during the last years by some correct and many incorrect arguments. The ACS/Jäckering–MDM (modified dry milling) – process has been developed to avoid as far as possible these arguments (even if incorrect) and fulfilling the following criteria: • The energy balance is positive (1:3.5). • The CO2 –reduction of the biofuel produced is larger than 80% (according to newest Directive 2009/28/EC. • All components of the raw material (wheat) going into the plant are utilized and leaving the plant as biofuel and high value co-products. Therefore no waste or waste water is produced. • All gaseous emissions are well below standard EC-requirements. • The plant operation is economic in a wide range of feedstock costs. • The income from food and fodder products is higher than the income from bioalcohol.. In order to fulfill the before mentioned requirement 8 innovative steps are applied. The steps themselves are not new and some have been in successfully operation in other industries for more than 2 decades, however the combination as such bioalcohols is new. In the paper the innovative steps will be discussed in details based on a standard production line of 200’000 l/day EtOH (50’000 t/year EtOH) and multiples of 2 to 6 lines.
