“…In several studies on this subject, significant amount of revenues have been attributed to the refined glycerin. However, since this is not the state of the market currently, no revenues from glycerin commercialization have been projected in the present case study (Apostolakou et al, 2009).…”

The present work is about the techno-economic evaluation of a biodiesel industrial unit that exclusively use recycled edible oils as feedstock, for two alternative production technologies. Nowadays, many biodiesel production units use a mixture of virgin vegetable oils and waste cooking oils. The examined unit will use only waste cooking oil as raw material. Thus, two different methods for biodiesel production are assessed on a financial basis for different biodiesel prices. The investigated methods are the alkaline transesterification (a very common biodiesel production method) and the supercritical transesterification (a method with non sensitivity in moisture and free fatty acids and thus not requiring a pre-treatment stage). According to the financial evaluation, the acceptance of the project for each technology is strongly affected by biodiesel's price. The results showed that the alkaline transesterification based project is accepted for the whole examined prices' range while for supercritical transesterification, the project is accepted for biodiesel prices of about 0.75-0.85 €/L.

“…The boiling temperature of triolein was specified to be 548.3 • C [34] rather than 846 • C available in ASPEN plus since previous studies have established that the boiling point temperature for triolein present in the ASPEN plus database is overestimated [34].…”

Abstract:In response to existing global focus on improved biodiesel production methods via highly efficient catalyst-free high temperature and high pressure technologies, this study considered the comparative study of catalyst-free technologies for biodiesel production as an important research area. In this study, therefore, catalyst-free integrated subcritical lipid hydrolysis and supercritical esterification and catalyst-free one step supercritical transesterification processes for biodiesel production have been evaluated via undertaking straight forward comparative energetic and environmental assessments. Energetic comparisons were undertaken after heat integration was performed since energy reduction has favourable effects on the environmental performance of chemical processes. The study confirmed that both processes are capable of producing biodiesel of high purity with catalyst-free integrated subcritical lipid hydrolysis and supercritical esterification characterised by a greater energy cost than catalyst-free one step supercritical transesterification processes for an equivalent biodiesel productivity potential. It was demonstrated that a one-step supercritical transesterification for biodiesel production presents an energetically more favourable catalyst-free biodiesel production pathway compared to the integrated subcritical lipid hydrolysis and supercritical esterification biodiesel production process. The one-step supercritical transesterification for biodiesel production was also shown to present an improved environmental performance compared to the integrated subcritical lipid hydrolysis and supercritical esterification biodiesel production process. This is because of the higher potential environment impact calculated for the integrated subcritical lipid hydrolysis and supercritical esterification compared to the potential environment impact calculated for the supercritical transesterification process, when all material and energy flows are considered. Finally the major contributors to the environmental outcomes of both processes were also clearly elucidated.

Abstract:In this research, a new cultivar of Camelina "Soheil" seed oil (CSO) was investigated as a novel feedstock for biodiesel production. Maximum oil content of CSO seed was about 29%. Physical and chemical characteristics of CSO were investigated. The biodiesel production process was optimized by using the response surface methodology (RSM) reaction parameters, including molar ratio (methanol to oil), reaction time, and concentration of catalyst are studied. The result showed that the conversion of biodiesel was 98.91% under the optimized conditions of 10.18:1 molar ratio and 1.15 wt % concentration of catalyst for a reaction time of 7.33 min. By investigating the properties of the fuel, it turned out that biodiesel from new cultivar of CSO oil complied with the limits prescribed in the ASTM D6751 standards, and that this seed oil could be introduced as a new feedstock for biodiesel production. Also, the performance and emission of a diesel engine were investigated with CSO biodiesel. All of the engine experiments were performed under the constant speed of 2100 rpm at loads of 0%, 25%, 50%, 75%, and 100%. Results indicated that by using the biodiesel-diesel blends, the brake power, and the CO 2 and NOx emissions increased, while the SFC and CO and UHC emissions decreased.
