CEP: March 2015 This issue's Society for Biological Engineering supplement focuses on biofuels. It's articles explore the need for biofuels and producing biofuels from lignocellulose by thermochemical conversion, fermentation of sugar, and via carboxylate salts. Scaling up bioenergy technologies and the commercial-scale production of lignocellulosic biofuels are also discussed. Other topics in this issue include process safety lessons learned and modeling aqueous electrolyte systems. Editorial Energy Cost Averaging Last year, when we chose biofuels as the topic for this issue’s Society for Biological Engineering (SBE) supplement, we did not anticipate the precipitous drop in oil prices of recent months. As we were pulling the articles together, guest editor Mark Holtzapple expressed concern that oil prices would be low when the issue appears. “If readers do not think too deeply, they might say ‘These academics are sure out of touch. Don’t they know oil prices are low?’” Read more Share Lessons Learned from Recent Process Safety Incidents March2015Back To BasicsAlbert NessThese ﬁve incidents demonstrate how seemingly small mistakes or temporary lapses in judgment can result in disaster. Modeling Aqueous Electrolyte Systems March2015Computational MethodsChau-Chyun Chen, Soraya Honarparvar, Sina Hassanjani SaraviAccurate thermodynamic models are needed to simulate processes involving electrolytes, which range from hydraulic fracturing to CO2 capture and sequestration and basic chemicals manufacturing. Follow these steps to develop thermodynamic models for your electrolyte system. SBE Special Section: Lignocellulosic Biofuels - SBE Update March2015SBE Special SectionDarlene SchusterConsidering that the price of oil has plummeted to less than half of what it was a year ago, this SBE supplement on biofuels is quite well-timed. What role can and will biofuels play, both today and in the future? SBE Special Section: Lignocellulosic Biofuels - Meet the Authors March2015SBE Special Section SBE Special Section: Lignocellulosic Biofuels - The Need for Biofuels March2015SBE Special SectionBruce E. Dale, Mark HoltzappleAs fossil energy resources decline, we must develop and deploy renewable energy systems. An attractive alternative is to convert lignocellulosic biomass into transportation fuels. SBE Special Section: Lignocellulosic Biofuels - Producing Biofuels via the Thermochemical Platform March2015SBE Special SectionRobert Brown, Sergio C. CaparedaThermochemical conversion of biomass to liquid fuels employs many of the same processes and equipment as are used with fossil fuel feedstocks. SBE Special Section: Lignocellulosic Biofuels - Producing Biofuels via the Sugar Platform March2015SBE Special SectionBruce E. Dale, Charles WymanWhether the feedstock is sugarcane, corn, or lignocellulose, the fermentation and ethanol recovery operations are similar. The differences arise in the way the sugars are released and the co-products produced. SBE Special Section: Lignocellulosic Biofuels - Producing Biofuels via the Carboxylate Platform March2015SBE Special SectionMark Holtzapple, Sagar Lonkar, Cesar GrandaThe carboxylate platform ferments a wide variety of biomass feedstocks into mixed carboxylic acids and their salts, which in turn can be transformed into hydrocarbon fuels. SBE Special Section: Lignocellulosic Biofuels - Scaling Up Bioenergy Technologies March2015SBE Special SectionDavid EdwardsThe stage-gate technique used for traditional chemical processes must be modified for bioenergy technologies. Follow these recommendations to minimize risk and maximize success.
