Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

Green Car Congress

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Water from mining of oil sands and oil shale.

Critical review finds actual measurement data on segments of natural gas lifecycle sparse or lacking

Green Car Congress

This surge in exploration and production from unconventional sources has been accompanied by public concerns about various environmental issues—including air quality, water quantity and quality, and human health impacts. Measurements on the variation of air emission composition and magnitude by natural gas and oil plays need to be made.

60% of ground-level ozone (O 3 ) precursors, 6% of fine particulate matter (PM 2.5 ), and 22% of greenhouse gases (GHGs) emitted. not reformulated) gasoline; and (4) crude oil production is 100% conventional crude (most oil sands production occurs outside of our spatial modeling domain—i.e., the contiguous US).

National Academies Report Examines Hidden Cost of Energy Production and Use in US; Estimates $120B in 2005

Green Car Congress

A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. of the estimated total.
