The Brinkman method is one of several approaches used to predict the effective viscosity of oil-water mixtures, and is effective in simulations when one or the other phase is dominant. However, a significant level of uncertainty exists in mixtures where the oil and water levels are comparable. Engineers from software developer AspenTech (Burlington, Mass.; www.aspentech.com) have applied a proprietary...

Gold catalysts have been shown to have superior activities for oxidation reactions, especially at low temperature, compared to other metal-based catalysts. But the high price of gold makes it necessary to develop Au catalysts with ever-higher activities, reducing the amount of Au needed. A promising step in this direction is a new type of catalyst developed by Professor Naoki Toshima and his research group...

Hydrofoil turbines mounted inside gravity-fed water-effluent conduits can generate significant electrical power without impeding flow, a demonstration project has shown. The in-pipe turbine systems offer chemical process industries (CPI) companies a way to extract emission-free energy from flowing wastewater discharge pipes. Based on hydropower research by Northeastern University professor Alexander...

Bio bisabolene Through genetic engineering of microbes, scientists from Lawrence Berkeley National Laboratory’s (Berkeley, Calif.; www.lbl.gov) Joint BioEnergy Institute (JBEI) have coaxed both bacteria (Escherichia coli) and yeast (Saccharomyces cerevisiae) to produce a chemical precursor to bisabolane — a critical step toward an improved renewable diesel alternative. The precursor can be...

Using an array of lamps inside a highly reflective chamber, the optical cavity furnace (OCF) takes advantage of photonics effects to help manufacture solar photovoltaic cells with higher efficiency than those made by conventional rapid-thermal-processing (RTP) methods. In addition, the OCF can reduce cost and raise efficiency of the manufacturing process itself. Scientists at the U.S. Dept. of...

In combustion, the ratio of fuel to air is key to efficiency, emissions control and stable performance of the combustion system. Adjusting this ratio to accommodate variability in fuels — due to the use of different fuels, and the variability that naturally occurs with some of the lower-cost fuels and renewable fuel sources — is a difficult task. Emerson Process Management (St...
