A broader assessment of the sustainability of ethanol must account for those … issues, as well as economic and social aspects. Sugarcane-derived ethanol produced in Brazil has been considered one of the …

evaluated in the initial screening process. This work uses the cases of corn and sugarcane ethanol to draw some comparisons on … and second generation technologies in the same site processing corn or sugarcane for ethanol. …

This paper examines the possibilities of breaking into the cellulosic ethanol market in south Louisiana via strategic …

This study carried out an exergetic analysis of a proposed ethanol production scheme in which a new process – enzymatic … hydrolysis of sugarcane bagasse – is integrated into the conventional process. Seven cases were evaluated, among them a … conventional ethanol production plant without hydrolysis, a conventional plant combined with hydrolysis and hydrolysate …

Sugarcane is one of the most important industries of the Brazilian economy, and its main products are sugar and ethanol …. Most of the industrial plants produce both products in an integrated process, in which the sugarcane bagasse is a by … analysis is used to assess an integrated sugar and ethanol plant with its cogeneration system. The plant was divided into eight …

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 … autonomous distillery processing sugarcane were assessed through simulation using Aspen Plus. Second generation ethanol …

Sugarcane trash and bagasse, lignocellulosic materials obtained during sugarcane harvesting and processing, may be used … 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 …

One of the key issues that must be addressed in the biofuel production based on sugarcane industry is the energy … feedstock for second generation ethanol production. A significant fraction of the energy consumption in bioethanol production … concentration and, consequently, produce wine of low (around 8.5°GL) ethanol content that must be distilled in order to meet product …

Ethanol is produced in large scale from sugarcane in Brazil by fermentation of sugars and distillation. This is … of these alternative fermentation processes in ethanol production, energy consumption and electricity surplus produced in … ethanol production increases between 3.3% and 4.8% and a reduction in steam consumption happens of up to 36%.
