Ethylene is a growth hormone for fruits and vegetables that is generated by the plants themselves; that is, it acts as a self-ripening agent. Hence, the removal of ethylene gas can play a central role in maintaining the freshness of these products. Whereas the temperature and the levels of oxygen and carbon dioxide gases are also important system variables that demand a significant economic invest ...

The conversion of corn and other biomass to fuel grade ethanol not only would reduce U.S. dependence on foreign energy sources but also would be a major industrial application for agricultural products. However, the process of drying the ethanol to fuel grade consumes significant amounts of energy, incurring costs that continue to increase as cost of natural gas increases. This project will deve ...

The need for natural gas continues to grow, and recent increases in petroleum prices have been paralleled by large increases in the price of natural gas. However, natural gas at the source often has high concentrations of carbon dioxide and hydrogen sulfide, which must be removed. Although existing commercial polymeric membranes (e.g. cellulose acetate and polysulfone) do a good job of sweetenin ...

A. Water must be removed from biodegradable hydraulic fluids as they react with water and degrade insitu. B. Biodegradable hydraulic fluids for farm equipment provide a significant improvement over traditional petroleum based fluids due to decreased pollution. Increase the use and value of biodegradable hydraulic fluids by development of a membrane-based dewatering system.

The use of biodiesel offers significant advantages with regards to the reduction of total harmful engine emissions with the exception of NOx. Biodiesel is a renewable resource and soybean oil is known to be economically viable as a biodiesel fuel. Recent studies from the Environmental Protection Agency have shown that soybean oil alone or blended with #2 diesel fuel results in a significant decrea ...

In the electrical power, steel production, and aluminum production industries, flame retardant, phosphate-ester hydraulic fluids are used to minimize fires. Although these fluids accomplish the fire-minimization task, they are unstable, which causes performance to suffer with attendant losses in productivity. This project will develop novel, chemically-resistant high-flux membranes that can remo ...

Distillation is a major chemical unit operation and consumer of significant energy. Often, water or another intermediate boiling component can become trapped within the distillation column and accumulate. This causes various operating difficulties such as flooding, slugging, cycling, instability, and an off-spec product. This project will develop a chemically resistant, non-porous water-venting ...

Catalysis plays a substantial role in the synthesis of the most U.S. commodity chemicals, with huge implications for energy usage. Membrane reactors have been proposed for a number of these syntheses. However, to be competitive with conventional technologies, membrane reactors must demonstrate better selectivity, permeability, and/or stability. This project will develop a novel platform with ke ...

The use of ethanol as a fuel would impact U.S. reliance on foreign oil. However, among the economic obstacles to it widespread use are the costs of shipping fuel-grade ethanol by truck. Shipping ethanol by pipeline would be significantly less expensive, but, unfortunately, pipeline ethanol is hydroscopic, which causes too much water to be present in the fuel. This project will develop a simple, ...

Small engines such as those found in All Terrain Vehciles are very polluting and are a major source of air pollution in the US. This project will build on Phase I research by building functional prototypes that can be tested in terms of emissions reduction, performance, and cost.
