Pumping water from coal seams decreases the pressure in the seam and in turn releases trapped methane; this is the most common and economic method of methane extraction. The water that is pumped out is known as "coal-bed methane water" (CBMW), which is high in sodium and other salts. In...
Coal-bed natural gas production in the U.S. in 2012 was 1655 billion cubic feet (bcf). A by-product of this production is co-produced water, which is categorized as a waste product by the Environmental Protection Agency. The effects of varying concentrations of coal-bed methane (produced) water were studied in the greenhouse...
The potential to use camelina (Camelina sativa L.) as a bioenergy crop has increased the need to develop management practices that would improve sustainable production. This study evaluated the effects by cultivars (Blaine Creek, Pronghorn, and Shoshone) and three spring seeding dates on the performance of camelina grown under rain-fed...
A steam distillation extraction kinetics experiment was conducted to estimate essential oil yield, composition, antimalarial, and antioxidant capacity of cumin (Cuminum cyminum L.) seed (fruits). Furthermore, regression models were developed to predict essential oil yield and composition for a given duration of the steam distillation time (DT). Ten DT durations...
Ocimum basilicum L. (sweet basil) is an essential oil producing crop used in culinary and fragrance applications. The objective of this controlled environment study was to evaluate the effects of organic and conventional fertilization (applied at two nitrogen rates, 150 and 250 kg N/ha) on plant growth, essential oil yield...
Cymbopogon flexuosus, lemongrass, and C. martinii, palmarosa, are perennial grasses grown to produce essential oils for the fragrance industry. The objectives of this study were (1) to evaluate biomass and oil yields as a function of nitrogen and sulfur fertilization, and (2) to characterize their utility for lignocellulosic ethanol compared...
Japanese cornmint, also known as menthol mint (Mentha canadensis L. syn M. arvensis L.), is an essential oil crop cultivated in several countries in Asia and South America. The plant is currently the only commercially viable source for natural menthol as a result of the high concentration of menthol in...
