Three different products of bagasse, namely, pellets, electricity, and ethanol, are considered. Large-scale testing of this process indicated that EB degradation of cellulose in wood chips would enhance the digestion rate for the production of paper or viscose. 2008). Such studies have been reported in literature for some sugar producing countries (Furlan et al., 2012, Ensinas et al., 2013). The use of ANN modelling in chemical processes has increased because of its simplicity in solving complex problems. SCB is composed of approximately 50% cellulose, 25% hemicellulose and 25% lignin (Huang et al. Jiri George Drobny, in Ionizing Radiation and Polymers, 2013. Bagasse is being used as a fuel source for sugar mills; when burned in quantity, it produces sufficient heat energy to supply all the needs of a typical sugar mill with energy to spare. Bagasse is 50% water and dry bagasse mass composition is considered to be 39% cellulose, 37% hemicellulose, 21% lignin and 3% ash. Table 17.2 summarizes the main bands observed in the FTIR spectrum of sugarcane bagasse cellulose with the corresponding functional groups and molecules. Utilization of sugarcane bagasse, therefore, poses a sustainability challenge with food, energy and water nexus. The Aspen Plus simulator was used to evaluate physicochemical properties (mixture boiling point, densities and heat capacities), as well as the heats of reaction. D. Varshney, ... Yogendra Shastri, in Computer Aided Chemical Engineering, 2018. Bagasse is burned as fuel in the sugarcane mill or used as a source of cellulose for manufacturing animal feeds. Across the industry, you will commonly find Bagasse takeaway containers, bagasse plates and bagasse … Sugarcane bagasse is a vegetal biomass that has much potential for use because of its structural elements: cellulose, hemicellulose and lignin. Simultaneously, the global warming potential (GWP) and water footprint for the same products are calculated to understand the environmental trade-offs. Kinetic constants were taken from Lavarack et al. The simulated process includes the enzymatic hydrolysis of sugarcane bagasse pretreated with liquid hot water, and the analyzed parameters were the solid consistency in the hydrolysis and pretreatment reactors and the hydrolysis reaction time. (2002) and our previous work (Lopez-Arenas et al., 2010): Cacid = 5%, Q = 0.0536 m3/min, V = 2 m3, T = 190°C (at a pressure of 12 atm), ϕ = 0.42. After oven dry ash was sieve in the mechanical shivers to separate unburned particles from ash. In ethanol production from sugarcane juice, sugarcane bagasse is used as fuel for the boiler, to meet the steam and electric energy demand of the process. For the economic scenario considered in this study, using bagasse to increase ethanol production yielded higher ethanol production costs compared to using bagasse for electric energy production, showing that further improvements in the process are still necessary. Source: Mulinari et al. By continuing you agree to the use of cookies. Currently, a large amount of bagasse is burnt as a low-grade fuel for energy recovery, and only a limited quantity has been used to make pulps, board materials, and composites. 2005). (2002). Different researchers have recorded different chemical compositions for bagasse and some are listed in Table 17.1. Originally used as a biofuel, the value of this material for the packaging industry has since been well explored. Copyright © 2020 Elsevier B.V. or its licensors or contributors. The SBS-g-MA contained 1.7% of MA and 30% of styrene. Yurany Camacho Ardila, ... Maria Regina Wolf Maciel, in Computer Aided Chemical Engineering, 2012. This process allows the use of heat to produce steam, as well as obtaining a gaseous fuel from the direct burning of biomass. Thus, cellulose and hemicellulose become more available for subsequent processes like chemical or enzymatic hydrolysis leading to improved fermentation procedure, for example, in the production of 2° generation ethanol. Bagasse is the waste from sugar cane plants left over after the sugar has been extracted. Black Friday Sale! It is currently being used … Bagasse is readily available as a waste product with a high sugar content and has potential as an environmentally friendly alternative to corn as a source of the biofuel ethanol (ethyl alcohol). Bagasse is now widely being used across the catering industry as a substitution for disposables made from wood, pulp, fibre, petrochemicals and plastics. The Gibbs free energy minimization method was used to predict the composition of the produced gas. Sugarcane bagasse is a highly promising source of biomass in the Indian context for the establishment of a bio-based economy. The main objective of this paper is to study the influence of operating temperature, the ratio biomass to gasification agent on hydrogen yield and the ratio CO/H2 of the effluent gas. The model predicts syngas composition, heating values and conversion efficiency in good agreement with published experimental data. Table 17.2. This article was most recently revised and updated by, https://www.britannica.com/technology/bagasse. Bagasse is commonly used as a filler for paper or fibreboard. The reactor design basis was taken according the proposal of Aden et al. Jaiver Efren Jaimes Figueroa, ... Maria Regina Wolf Maciel, in Computer Aided Chemical Engineering, 2012. Sugar cane bagasse ash passing from 300 micron was used in this experiment work. In modern use, the word is limited to the by-product of the sugarcane mill. Bagasse, also called megass, fibre remaining after the extraction of the sugar-bearing juice from sugarcane.
