Study of Technological Process of Fermentation of Molasses Vinasse in Biogas Plants

The volume of ethanol production waste—molasses waste in Ukraine—reaches up to 4 million m3 per year. It is not easy dispose and polluting the environment. Currently, development an effective technology for using molasses biogas plants obtain energy gas—biogas—is urgent problem. purpose our work determine rational loading bard into methane tank a quasi-continuous mode maximum biogas. To achieve this goal, following experimental studies were carried out: mono-fermentation combined fermentation cattle manure on laboratory plant periodic mode; basis obtained studies, special simulation model output during substrates was established amount added determined. under system when adding 10.5% 1.462 l/(h kg DOM); 26.1% manure, it 3.594 DOM). In order increase yield biogas, advisable add 30% substrate based which allows discounted payback period be reduced 1.2 years.
