- Bench-Scale Biopile Hydrocarbons Removal Optimization Using the Response Surface Methodology and Simultaneous Optimization Omar Gutiérrez-Benítez David J. Castro Rodríguez Víctor M. Serrano-Suárez Enmanuel Casals-Pérez Dayana Rabassa-Rabassa Roberto Núñez-Moreira Eudalys Ortiz-Guilarte María V. Iglesias-Rodríguez Ingeniería Box Biopile Behnken hydrocarbon removal simultaneous optimization Nowadays, the generation of vast volumes of oily sludges is associated with industrial operations such as production, pretreatment, processing, water separation, and storage tank maintenance. Biopiles can be more efficient than other techniques for removing hydrocarbons in sludges, but their removal efficiency depends on operating variables. The goal of this study was to determine the best operating variable ranges at the bench scale to simultaneously optimize hydrocarbons removal in a biopile prototype. This research was conducted within the framework of a Cuban project and used an experimental protocol that integrates several standardized methods and engineering procedures into a series of steps. A Box-Behnken design was implemented for three factors and two response variables: the mass of Total Petroleum Hydrocarbons (TPH) removed and the final concentration of TPH. A simultaneous optimum was obtained for an initial TPH concentration of 39 278 mg.kg-1 and contents of texturizer and moisture of 6,45 and 25,95%, respectively. The obtained variable ranges ensure a compromise solution that maximizes the mass of TPH removed and keeps the contaminant concentration under the Cuban disposal regulations. The results have been used to set up the biopiles at a pilot scale as a subsequent stage of the project. 2023 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379910004 https://www.redalyc.org/journal/643/64379910004/ https://www.redalyc.org/journal/643/64379910004/html/ https://www.redalyc.org/journal/643/64379910004/64379910004.epub https://www.redalyc.org/journal/643/64379910004/movil 10.15446/ing.investig.97848 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.2 Vol.43
