Available in PDF, EPUB and Kindle. Book excerpt: The dwindling resources of fossil fuels coupled with the steady increase in energy consumption have spurred research interest in alternative and renewable energy sources. Biodiesel is one of the most promising alternatives for fossil fuels. It can be made from various renewable sources, including recycled oil, and can be utilized in lieu of petroleum-based diesel. To foster market competitiveness for biodiesel, it is necessary to develop cost-effective and technically sound processing schemes, to identify related key design criteria, and optimize performance. The overall goal of this work was to design and optimize biodiesel (Fatty Acid Methyl Ester "FAME") production from vegetable oil. To achieve this goal, several interconnected research activities were undertaken. First, a base-case flow sheet was developed for the process. The performance of this flow sheet along with the key design and operating criteria were identified by conducting computer-aided simulation using ASPEN Plus. Various scenarios were simulated to provide sufficient understanding and insights. Also, different thermodynamic databases were used for different sections of the process to account for the various characteristics of the streams throughout the process. Next, mass and energy integration studies were performed to reduce the consumption of material and energy utilities, improve environmental impact, and enhance profitability. Finally, capital cost estimation was carried out using the ICARUS Process Evaluator computer-aided tools linked to the results of the ASPEN simulation. The operating cost of the process was estimated using the key information on process operation such as raw materials, utilities, and labor. A profitability analysis was carried out by examining the ROI (Return of Investment) and PP (Payback Period). It was determined that the single most important economic factor is the cost of soybean oil, which accounted for more than 90% of the total annualized cost. Consequently, a sensitivity analysis was performed to examine the effect of soybean oil cost on profitability. It was determined that both ROI and PP quickly deteriorate as the cost of soybean oil increases.

This book was released on 2018-01-17 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project Report from the year 2017 in the subject Engineering - Industrial Engineering and Management, , language: English, abstract: The conventional approach of biodiesel production is transesterification, using oil and alcohol in the presence of a catalyst with glycerol as a by-product of the reaction. Product quality is dependent on the type and amount of catalyst, type of oil feedstock, alcohol-to-oil ratio, etc. In terms of the best process, currently the alkali catalyzed process is the most profitable while the enzymatic based one is even more promising due to the lower consumption of energy and water; however it requires that the enzyme cost is reduced. The reason that biodiesel is not utilized widely around the world is due to the high cost of raw materials. To overcome this, one can use lower quality oils, such as Waste Cooking Oil (WCO). A lot of research has been carried out on the production of biodiesel from fresh vegetable and animal oil sources but the use of Waste Cooking Oil, such as palm oil, etc. has not been well documented. Then the aim of this current project is to analyze and optimize the conditions for biodiesel production from Waste Cooking Oil, by investigating interaction effects among process variables (temperature, oil-to-methanol molar ratio and catalyst loading) using SPC and other tools. Thus this project focuses on making biodiesel processes better and more efficient.

Available in PDF, EPUB and Kindle. Book excerpt: Although the compression ignition (C.I.) engine, invented by Rudolf Diesel, was originally intended to work with pure vegetable oils as fuel, more than a century ago, it was adapted to be used with a fuel of fossil origin, obtained from oil. Therefore, there would be no technical difficulties in returning to the primitive design of using biofuels of renewable origin, such as vegetable oils. The main drawback is found in the one billion C.I. engines which are currently in use, which would have to undergo a modification in the injection system in order to adapt them to the higher viscosity of vegetable oils in comparison to that of fossil fuels. Thus, the gradual incorporation of biofuels as substitutes of fossil fuels is mandatory.

This book was released on 2013-06-10 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: A significant source of uncertainty in biodiesel production is the variability of feed composition since the percentage and type of triglycerides varies considerably across different raw materials. Also, due to the complexity of both transesterification and saponification kinetics, first-principles models of biodiesel production typically have built-in errors (structural and parametric uncertainty) which give rise to the need for obtaining relevant data through experimental design in modeling for optimization. A run-to-run optimization strategy which integrates tendency models with Bayesian active learning is proposed. Parameter distributions in a probabilistic model of process performance are re-estimated using data from experiments designed for maximizing information and performance. Results obtained highlight that Bayesian optimal design of experiments using a probabilistic tendency model is effective in achieving the maximum ester content and yield in biodiesel production even though significant uncertainty in feed composition and modeling errors are present.

Available in PDF, EPUB and Kindle. Book excerpt: Resource-efficient technologies are essential for economically viable biodiesel production. This work focuses on conversion of microalgal lipids and vegetable oils into fatty acid alkyl esters or biodiesel. Transesterification of waste cooking oil (WCO) and extractive-transesterification of wet microalgal biomass were investigated using microwave and ultrasound irradiations through several process parametric evaluation studies to elucidate the effects of different alcohols and catalyst types (homogeneous and heterogeneous), reaction time, and reaction temperatures. First, a brief overview of process steps involved in microalgal biodiesel production and associated energy consumption and research needs were discussed. Next, energy analysis of microalgal biocrude production via extractive-transesterification under microwave and ultrasound irradiations (individually) was performed. Then, the synergistic effect of microwave and ultrasound irradiations on extractivetransesterification of microalgal lipids was evaluated through a process optimization study using response surface methodology to determine the best process conditions. For this study, a maximum biocrude conversion of 51.2% was obtained when 20 g of algal paste was treated with 30 mL methanol, 1 wt.% catalyst, 7 min reaction time, and 140 W for MW and US (280 W total). Further, biocrude yield kinetics study revealed that the activation energy for this reaction was around 17, 298 J mol-1 K-1. A series of experimental studies were conducted to understand the roles and effects of various process related conditions including the power output and power density of microwave and ultrasound irradiations in biodiesel production. The two nonconventional heating techniques were compared for their process intensification effects. Ultrasound was applied either in continuous or pulse mode. Pulse sonication was found to be more suitable for simple transesterification reaction of WCO with a 98% biodiesel yield in 2.5 min (9:1 methanol to oil ratio, 1.25% catalyst, and 150 W power output) over 82% yield for continuous sonication under the same conditions. Followed by this, a detailed study was conducted to determine optimum pulse (ON and OFF time) sonication conditions. A 99% conversion yield was obtained for a pulse ON-OFF combination of 7s- 2s. Additionally, the effect of different alcohols (ethanol, methanol, and ethanol-methanol mixtures) using pulse sonication was evaluated.

This book was released on 2018-09-12 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2017 in the subject Environmental Sciences, grade: A, Andhra University (College of engineering), language: English, abstract: Biodiesel as an alternative fuel for diesel engines is becoming increasingly important due to diminishing petroleum reserves and the environmental consequences of exhaust gases from petroleum-fueled engines. Biodiesel, which is made from renewable sources, consists of the simple alkyl esters of fatty acids. As a future prospective fuel, biodiesel has to compete economically with petroleum diesel fuels. A two-step transesterification process (Sequential esterification and transesterification process) was used to prepare methyl ester (biodiesel) from high free fatty acid (FFA) content oils. For the yield of high FFA, two-step acid-base catalyzed method has been developed which consists of acid-catalyzed pretreatment/esterification step to reduce the FFA to less than 1% using H2SO4 as an acid catalyst and transesterification of pretreated oil to biodiesel using alkali catalyst. In the present study, the main focus is being placed to explore the non-edible oil resources like Used Cooking Oil (UCO), Cottonseed oil, Jatropha (Jatropha curcas) oil, Neem(Azadirachta indica) oil as a potential source for biodiesel. Experimental results from enzyme (lipase) catalyzed method for selected oils using influencing parameters such as reaction time and catalyst weight, experimental results from acid-alkaline catalyzed methods using common influencing parameters such as methanol to oil molar ratio, catalyst weight, reaction temperature and reaction time for above-mentioned oils were compared using batch mode. Methyl ester (biodiesel) yield range of 66.20-71.6% was attained for an enzyme-catalyzed method, whereas for acid-alkaline the yield range was 84.4-91.6%. This gives the indication of further refinement in the enzyme-catalyzed transesterification process. However, enzyme-catalyzed biodiesel production has some limitations especially when implemented in industrial scale because of the high cost of enzyme, low reaction rate and enzyme deactivation. As the catalyst, an enzyme is restricted to rigorous reaction condition and the activity loss of lipase. The influencing parameters and absolute results of the analysis give the impression of the superiority of acid-alkaline transesterification method for methyl ester production. In this study, we have selected Used Cooking Oil Methyl Ester (UCOME) and Jatropha Methyl Ester (JME) among the methyl esters of four oils.
