Creator:: Sahle-Demessie, Endalkachew
Abstract:: The temperature-time-location relationships during steam conditioning and pressure treatment of timber poles have been studied and mathematical models that take into account both the thermal properties of the poles and the parameters of the treatment process have been developed. Although much work has been previously done in this area, the...

Creator:: Anderson, Matthew E.
Abstract:: It is difficult to treat the heartwood of many wood species with liquid preservatives using conventional liquid processes. Supercritical fluids (SCF) used as carriers of preservatives to impregnate refractory wood species may be an attractive alternative to conventional liquid carriers. While SCF impregnation has many potential advantages, some wood species...

Full Text:: privacy. AN ABSTRACT OF THE THESIS OF Matthew E. Anderson for the degree of Master of Science in Forest

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....

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...
