The extraction of pentachlorophenol from pressure treated wood using supercritical carbon dioxide

Creator:: Yi, Jung-Seok
Abstract:: The extraction of pentachlorophenol (PCP) from pressure treated wood wafers with supercritical carbon dioxide has been studied. Experimental data were obtained for the effects of pressure (17.5 - 25.0 MPa), temperature (313 - 353 K), flow rate (1 - 3 ml/min at supercritical conditions), and sample size (0.8 x 10...

An evaluation into the optimization and application of supercritical fluid extraction and the processing impact on the components in filtrated buttermilk powder

Creator:: Spence, Amy J.
Abstract:: The milk fat globule membrane, a major component in buttermilk, contains many complex lipids known to be involved in a variety of biological processes. Phospholipids, including sphingolipids, exhibit antioxidative, anticarcinogenic, and antiatherogenic properties and have essential roles in numerous cell functions. Filtration coupled with supercritical fluid extraction (SFE) may provide...

Experimental investigation of supercritical heat transfer of carbon dioxide in parallel square microchannels with a single-wall constant heat flux boundary condition

Creator:: Zada, Kyle R.
Abstract:: In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat...

Supercritical fluid impregnation with biocides of wood using temperature reduction

Creator:: Kang, Sung-Mo
Abstract:: Supercritical fluid (SCF) impregnation is a promising preservative treatment method, however, the development of SCF processes has been slowed by a limited understanding of the process. Developing a better understanding of the effects of various process parameters on treatment results would allow for a more rational development of SCF impregnation....

Pressure measurement in wood as a method to understand impregnation processes : conventional and supercritical carbon dioxide

Creator:: Schneider, Philip F.
Abstract:: Two approaches to improving wood treatability include the modification of pressure schedules during conventional liquid treatments and the use of supercritical fluids (SCFs). In both of these techniques, pressure differences are important for transporting materials into wood. The level of pressure and its change during SCF treatments are also important...

Experimental Characterization of a Supercritical Carbon Dioxide Microchannel Solar Thermal Receiver

Creator:: L'Estrange, Thomas
Abstract:: Characterization of a microchannel solar thermal receiver for supercritical carbon dioxide (sCO₂) is presented. The receiver design is based on conjugate computational fluid dynamics and heat transfer simulations as well as thermo-mechanical stress analysis. Two lab scale receivers with a 2x2 cm² absorber area are fabricated and experimentally characterized -...
