MORALES-ZAMORA, Marlén et al. Investor studies for the production of furfural-ethanol and boards from bagasse of sugar cane. Rev. ion [online]. 2021, vol.34, n.2, pp.17-29.  Epub 27-Jul-2021. ISSN 0120-100X.  https://doi.org/10.18273/revion.v34n2-2021002.

Nowadays, take advantage of facilities in the industry to modify, reanimation or revamping their productions is necessary for the reduction of investment costs and the increase of the availability of the plants. In this sense, the investigation aims to carry out a prior investor study in a sugar complex with installed derivatives plants, for the joint production of furfural, ethanol, and boards from bagasse, considering the revamp of the industrial facility. For this, it starts from modifications and results obtained by Mesa [1], in the bagasse fractionation stage towards getting glucose, xylose, and furfural and the use of residues in the board plant for Morales-Zamora [2]. Economic pre-feasibility studies are carried out for the plants separately along with the integration and revamp proposal. In the integrated analysis, a factorial design is proposed 24 considering the influence of the variables: sugarcane flow, ethanol flow, reliability and prices, for an optimistic scenario of prices and capacities. The economic results are favored for increases in the flow of ethanol, with a lower flow of cane, considering the reliability with the reconversion and with increases in the price of sugar. The reconversion towards obtaining sugar, electricity, furfural, boards and ethanol will be able to rescue installed plants and equipment, which would have an impact on minimizing investments, as well as a prospective development of adaptation of the sugar industry towards the concept of biorefinery.
