Title: | Process model and economic analysis of ethanol production from sugar beet raw juice as part of the cleaner production concept | Authors: | Vučurović, Damjan Dodić, Siniša Popov, Stevan Dodić, Jelena Grahovac (Ranković), Jovana |
Issue Date: | 1-Jan-2012 | Journal: | Bioresource Technology | Abstract: | The batch fermentation process of sugar beet processing intermediates by free yeast cells is the most widely used method in the Autonomous Province of Vojvodina for producing ethanol as fuel. In this study a process and cost model was developed for producing ethanol from raw juice. The model can be used to calculate capital investment costs, unit production costs and operating costs for a plant producing 44. million. l of 99.6% pure ethanol annually. In the sensitivity analysis the influence of sugar beet and yeast price, as well as the influence of recycled biomass on process economics, ethanol production costs and project feasibility was examined. The results of this study clearly demonstrate that the raw material costs have a significant influence on the expenses for producing ethanol. Also, the optimal percentage of recycled biomass turned out to be in the range from 50% to 70%. © 2011 Elsevier Ltd. | URI: | https://open.uns.ac.rs/handle/123456789/16136 | ISSN: | 09608524 | DOI: | 10.1016/j.biortech.2011.10.085 |
