This study carried out an exergetic analysis of a proposed ethanol production scheme in which a new process – enzymatic … conventional ethanol production plant without hydrolysis, a conventional plant combined with hydrolysis and hydrolysate … with their exergetic cost. For the conventional process, in which ethanol and surplus electricity are the major products, a …

Sugarcane is one of the most important industries of the Brazilian economy, and its main products are sugar and ethanol … analysis is used to assess an integrated sugar and ethanol plant with its cogeneration system. The plant was divided into eight …, which produce sugar and ethanol, were used in the process simulation. The analysis has shown that the sub-systems with the …

Sugarcane bagasse and trash may be used as feedstock for second generation ethanol production. Production of second … generation ethanol integrated with first generation plants processing sugarcane presents several advantages over the stand …-alone second generation ethanol production process; however, bagasse is used as fuel to supply the energy demand of the first …

warming potential (GWP) and human health indicators of sugarcane ethanol production in Brazil, in the pre-mechanization (100 …% burned), current (∼50% burned) and future (100% without burning) scenarios, were calculated. In the past, the GWP of ethanol … (DALY) was 3.16E−05DALYL−1 ethanol. The current ethanol production process has a GWP 46% smaller, while BC emissions are …

as fuels for electricity production and/or as feedstock for second generation ethanol. If electricity prices are … favorable, more lignocellulosic material may be diverted for production of steam and electricity, and vice versa when ethanol … prices are more attractive. Therefore, some flexibility to divert bagasse and trash for either second generation ethanol or …
