A TECHNO-ECONOMIC ANALYSIS OF BIODIESEL PRODUCTION FROM MICROALGAE
Environmental Engineering and Management Journal › Vol. 12 › Nr. 8 AbstractThe preliminary assessment of a cost-effective flow-sheet for the production of biodiesel from microalgae lipid fraction wascarried out. The study was based on approximated cost-estimation methods integrated with the simulation software Aspen Plus®.Several scenarios were investigated to compare costs regarding the main steps of the biodiesel production process. Ranges ofinput variables from downstream literature and experimental data were used to simulate the sections that define concret...

FROM SEEDS TO BIODIESEL: EXTRACTION, ESTERIFICATION, TRANSESTERIFICATION AND BLENDING OF Jatropha curcas OIL
Environmental Engineering and Management Journal › Vol. 14 › Nr. 12 Abstract
The aim of this research was to find the optimal method of extracting oil from jatropha seeds and to discovery a technically
viable process in which high quality biodiesel can be produced. To begin with, the oil extraction yield obtained with solvent
extraction was 34%, using n-hexane in 2 hours. Then, the properties and fatty acid composition of jatropha oil were investigated.
We must emphasize that jatropha oil contains about 11% of free fatty acids (FFA), which is far beyond the ... Autori: Carmen María Fernández ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26909
TREATMENT OF BIODIESEL WASTEWATER BY SOLVENT EXTRACTION: EVALUATION OF KINETIC AND THERMODYNAMIC DATA
Environmental Engineering and Management Journal › Vol. 17 › Nr. 11 Transesterification is one of the main biodiesel production method that produces huge amount of wastewater due to the high organic substance content (COD =300000-400000 mg/L, oil and grease= 17000-25000 mg/L). Although there are several treatment methods, flotation is the current conventional treatment method for oil and grease (O&G) before the biological treatment. In this study solvent extraction method was developed for pre-refining of biodiesel wastewaters. For the solvent extraction met...
