A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozonegas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Water from mining of oil sands and oil shale. Heavy metals in soil.
The first peer-reviewed study to directly quantify how emissions from oil and natural gas (O&NG) activities influence summertime tropospheric ozone (O 3 ) pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.
Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said.
The US Environmental Protection Agency (EPA) proposed standards to reduce harmful air pollution from oil and gas drilling operations. Natural gas production in the USis growing, with more than 25,000 new and existing wells fractured or re-fractured each year.
The US Environmental Protection Agency (EPA) released its latest set of proposed standards to reduce emissions of methane and volatile organic compounds (VOCs) from the oil and natural gas industry. The proposal also includes incentives to spur the oil and gas industry to minimize leaks.
NOAA’s updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend. NOAA scientists created the AGGI recognizing that carbon dioxide is not the only greenhouse gas affecting the balance of heat in the atmosphere.
Researchers at Japan’s Central Research Institute of Electric Power Industry (CRIEPI), in a project funded by the New Energy and Industrial Technology Development Organization (NEDO), have successfully developed a method to extract oil from algae using liquefied dimethyl ether (DME) at room temperature in high yield.
After a critical review of the literature on the air impacts of increased natural gas acquisition, processing, and use, a team of US researchers has determined that that actual measurement data on various individual segments of the natural gas life cycle are sparse or critically lacking. well production end-of-life.
Depletion of fossil energy resources [kg oil-eq.]. Deterioration of the ozone layer [kg CFC-11-eq.]. The program guides the interested layperson through a selection of parameters: which type of engine should be used, gasoline-burning or diesel, for example, or one powered by natural gas, a fuel cell, or a battery. in review).
In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone.
The Bakken Formation, a shale oil and gas field in North Dakota and Montana, is emitting roughly 2% (about 250,000 tons per year) of the globe’s ethane, according to new study led by researchers at the University of Michigan. Between 2005 and 2014, the Bakken’s oil production jumped by a factor of 3,500, and its gas production by 180.
coal, oil, natural gas, and biomass). Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels. Seasons and times of day.
Pechman for the Western District of Washington has ruled that the Washington Department of Ecology, Northwest Clean Air Agency, and Puget Sound Clean Air Agency must regulate greenhouse gas emissions (GHGs) from the five oil refineries operating in Washington State. Washington’s SIP was adopted pursuant to the US Clean Air Act (CAA).
The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions.
When ethane and propane—the most abundant non-methane hydrocarbons (NMHC) in the atmosphere—mix with nitrogen oxides from vehicles and power plants they form tropospheric ozone—a key component of smog and directly linked to increases in mortality. —Professor Ally Lewis, a co-author of the study.
The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone. These compounds in un-burned gasoline and diesel fuel dominate vehicular emissions of reactive gas-phase carbon that have the potential to form SOA.
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. An important analytical issue that needs to be addressed, the report notes, is the lack of lifecycle assessment studies focusing on a wider set of environmental impact indicators than greenhouse gas emissions.
eutrophication; ET = ecological toxicity; FEC = fossil energy consumption; WU = water use; LO = land occupation; “The rest” includes acidification; smog formation; ozone layer depletion; and human health effects. For gasoline, the study reflects the US context in which crude oil is to a large extent imported and refined domestically.
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.
The two vehicles, working together to gather upwind and downwind readings of sources, will monitor for methane, nitrous oxide, carbon dioxide, halocarbons, sulfur hexafluoride, carbon monoxide, ozone and particulate elemental carbon; as well as particulate matter size and distribution. While California’s population is less than 0.5%
The California Air Resources Board’s latest state inventory of greenhouse gas emissions shows that California’s GHG emissions continue to decrease. It does not include emissions from petroleum refineries and oil production. Source: ARB. MMTCO 2 e (6%) from 2013 to 2017.
Engine and drive system hoses require a particularly high level of oil and heat resistance. Since epichlorohydrin offers exceptional oil resistance, heat resistance, heat aging resistance, ozone resistance, and gas permeability, it is currently commonly used as a key compound in the production of rubber for components such as hoses.
Greenhouse gas emissions. The extent to which using biofuels rather than petroleum will reduce greenhouse gas emissions is uncertain, the report says. The best cost estimates of cellulosic biofuel are not economical compared with fossil fuels when crude oil’s price is $111 per barrel. Economic effects.
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).
The major sources of methane in California are livestock (~30% of the state’s methane emissions), followed by landfills and oil and gas production. Methane is 72 times more efficient at trapping heat in the atmosphere than CO 2 , which is the most prevalent global warming gas. CO 2 remains in the atmosphere for up to a century.
NO x is a precursor for both ground level ozone and secondary PM 2.5 It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions.
That study provided estimates of vessel traffic (numbers of vessels and transits) based on modeling of current vessel activity patterns, growth potential, and vessel projection scenarios, including diversion from other routes, and oil and gas development. more stringent requirements applicable to ships in Emission Control Areas (ECA).
The US Environmental Protection Agency (EPA) and the US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) jointly released the finalized Phase 2 greenhouse gas and fuel efficiency standards for medium- and heavy-duty trucks. The final standards are expected to lower CO 2 emissions by approximately 1.1
The bill also modifies the Clean Air Act to require the development of greenhouse gas emissions standards for all other mobile sources—e.g., Within three years of enactment, the EPA would need to determine the lifecycle greenhouse gas emissions of all transportation fuels and determine the fuel emission baseline.
The move to reduce the number of polluting trucks on the road integrates with a series of other measures to reduce vehicular air pollution in Haifa Bay, such as the massive installation of vapor recovery systems in gas stations, the move to convert buses and garbage trucks to natural gas, and more. Air pollution, Haifa. Source: MoEP.
Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). Chester and Horvath (2009).
A new interactive mapping tool shows how a growing number of US cities and states have passed regulations restricting the use of gas-powered lawn equipment, or incentivizing the use of electric equipment, with big clean air benefits for a comparatively small investment.
Together, the proposals would reduce oil imports by approximately 20 billion barrels. EPA projects that the proposed standards would avoid nearly 10 billion tons of CO 2 emissions—equivalent to more than twice the total US CO 2 emissions in 2022—through 2055.
Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.
Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and of oil and natural gas. Reduced gas leakage from long-distance transmission pipeline.
The US Environmental Protection Agency (EPA) issued final updates to its 2012 volatile organic compounds (VOCs) performance standards for storage tanks used in crude oil and natural gas production and transmission. In addition, the rule streamlines compliance and monitoring requirements for tanks that have already installed controls.
The Environmental Protection Agency (EPA) announced a new review of the Ozone National Ambient Air Quality Standards (NAAQS). In October 2021, EPA announced a reconsideration of the previous Administration’s decision to retain the NAAQS for ozone. In many of the areas designated as not meeting the current 2015 standards, work remains.
Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health. Tropospheric ozone and black carbon (BC) contribute to degraded air quality and global warming.
The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil.
The high voltage ionized the gas within the glass tube, creating the purple glow that gave the device its name. Ozone mode was for inhaling, to treat lung disorders. For example, a rake-shaped attachment worked to massage the scalp, while a narrow tube could be inserted into the mouth, nose, or another orifice. Renulife Electric Co.
The people most at risk are primarily low-income, Latino and Black residents of Manchester, Harrisburg, Meadowbrook, Allendale, Northshore, and Galena Park just across the fence lines from oil refineries, plastics plants, and other industrial facilities. Long-term exposure to formaldehyde can cause certain types of cancers.
Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? cancel the launch.
