“…Furthermore, there are numerous specific evaluations of biofuels, like biodiesel (Zhang et al, 2003;van Kasteren and Nisworo, 2007;Araujo et al, 2010) and simulations of biofuel processes with specialised software, like Aspen HYSYS (West et al, 2008). Despite the fact that production costs of biofuels compared to fossil fuels are an important driver for biofuel demand, there are only a few approaches to compare different biofuel production processes with each other and with the established production of fossil fuels considering scale and learning curve effects in the production process.…”

Das Wichtigste in Kürze Executive SummaryCompetitive production costs compared to conventional fuels are imperative for biofuels to gain market shares, as current tax advantages for biofuels are only temporary. Comparing production costs of different biofuels with fossil fuels is a challenge due to the complexity of influencing factors. The objective of this research paper is threefold: 1) to project future biofuel feedstock prices based on the crude oil price development, the price index for agricultural products, growth in world population, growth in wealth per capita income, and change in energy consumption per capita, 2) to simulate production costs under consideration of likely economies of scale from scaling-up production size and technological learning and 3) to compare different biofuels and fossil fuels by scenario analysis.A calculation model for biofuel production is used to analyse projected production costs for different types of biofuels in Europe for 2015 and 2020. Unlike engineering oriented bottomup approaches that are often used in other biofuel studies, the macro-economic top-down approach applied in this study enables an economic comparison and discussion of various fuel types based on reference scenarios of crude oil prices of €50, €100, €150 and €200 per barrel.Depending on the specific raw material prices as well as the conversion costs, the analysis delivered a differentiated view on the production costs and thus on the competitiveness of each individual type of fuel.The results show that 2nd generation biofuels are most likely to achieve competitive production costs mid-to long-term when taking into account the effects from technological learning and production scale size as well as crude oil price scenarios between €50 and €200 per barrel for both reference years. In all crude oil price scenarios, bioethanol from lignocellulosic raw materials as well as biodiesel from waste oil are associated with high cost saving potentials which enable them to outperform fossil fuels and 1st generation biofuels. Modelling Production Cost Scenarios for Biofuels and Fossil Fuels in Europe AbstractThis paper presents the results of a calculation model for biofuel production costs in 2015 and 2020 based on raw material price projections and considering scale and learning effects. Distinguishing six types of biofuels, the paper finds that scale economies and learning effects are critical for 2nd generation biofuels to become competitive. In case these ef...

To investigate the effect of reactor performance/confi guration of biodiesel production on process parameters (mass & energy consumption, required facilities etc.), two diverse production processes (from vegetable oil) were implemented/designed using Aspen HYSYS V7.2. Two series reactors were taken into account where overall conversion was set to be 97.7% and 70% in fi rst and second processes respectively. Comparative analysis showed that an increase in conversion yield caused to consumption reduction of oil, methanol, cold energy and hot energy up to 9.1%, 22%, 67.16% and 60.28% respectively; further, a number of facilities (e.g. boiler, heat exchanger, distillation tower) were reduced. To reduce mass & energy consumption, mass/heat integration method was employed. Applying integration method showed that in the fi rst design, methanol, cold and hot energy were decreased by 49.81%, 17.46% and 36.17% respectively; while in the second design, oil, methanol, cold and hot energy were decreased by 9%, 60.57% 19.62% and 36.58% respectively.

Zhang et al (2003 a,b) e West et al (2007) compararam diferentes rotas de produção de biodiesel através de simuladores de processo. Foram avaliados os fluxos materiais e de energia e dimensionados os equipamentos, de modo a avaliar cada processo economicamente.…”

RESUMO -Foi simulada a produção de biodiesel a partir do óleo de soja e de dendê a nível industrial. As propriedades termodinâmicas mais importantes dos componentes foram estimadas pelo método de Constantinou e Gani. Foi mostrado que algumas alterações nas correntes de entrada do processo e nos equipamentos são necessárias se objetiva-se processar tanto o óleo de soja quanto o de dendê, a fim de gerar um combustível que atenda às principais normas nacionais e internacionais de qualidade. INTRODUÇÃONos últimos anos, o aumento da preocupação ambiental aliado à diminuição progressiva das reservas de petróleo mundiais tem motivado o estudo e desenvolvimento de tecnologias e fontes de energia sustentáveis. Nesse contexto, surgem os biocombustíveis e, dentre eles, o biodiesel.O biodiesel é uma alternativa ao diesel tradicional. É um combustível renovável, produzido a partir de óleos vegetais ou gordura animal através da transesterificação desses componentes com um álcool, normalmente metanol ou etanol. É biodegradável, atóxico e a sua queima emite menos poluentes do que a queima do diesel produzido a partir do petróleo (Meher et al., 2006).Com relação a matéria prima, os óleos e gorduras são constituídos por triglicerídeos, ésteres de glicerol e ácidos graxos. Os óleos vegetais podem ser obtidos de diversas fontes. Tratando-se de Brasil, dá-se especial atenção à soja, que é capaz de gerar de 400 a 650 litros de óleo por hectare. No entanto, é crescente no norte, nordeste e centro-oeste do país a utilização da palma (ou dendê), por sua elevada popularidade e produção de 5.500 a 8.000 litros de óleo por hectare (Oliveira et al., 2008).A produção do biodiesel começa com o tratamento do óleo. Este deve passar por processos de neutralização, para redução da acidez, e desumidificação. A matéria prima tratada segue para um tanque, onde é misturada com o álcool escolhido e o catalisador (se necessário). São conhecidas diversas vias de produção de biodiesel, dentre as quais destacam-se a catálise homogênea ácida, a catálise homogênea alcalina (sendo essa a mais comum), a catálise heterogênea, a pirólise, a catálise enzimática e o processamento com fluidos supercríticos (Oliveira et al., 2008;Innocentini, Área temática: Simulação, Otimização e Controle de Processos 1
