Emissions Valve Packing Technology Evolves to Reduce Methane Leaks

Methane (CH4) is the second largest source of greenhouse gas emitted in the US. In 2013, CH4 accounted for about 10 percent of all US greenhouse gas emissions from human activities. Methane’s half-life in the atmosphere is much shorter than that of carbon dioxide (CO2); however, it is significantly more efficient at trapping radiation. Pound for pound, the comparative impact of CH4 on climate change is 25 times greater than that of CO2 during a 100-year period.

One area responsible for contributing to the increase in CH4 is leaking equipment in the oil and gas sector.  A major contributor to this leakage is valves that leak CH4 and sub-derivatives called volatile organic compounds (VOC) from the gland.

FSA Responds to ICF Report

(October 5, 2015) – A new report by leading energy industry consultancy ICF International (ICF) released today found that emissions of the potent greenhouse gas methane from the Canadian oil and gas sector can be reduced by 45% below projected 2020 levels, all while using existing, proven and cost-effective technologies. As the leading trade association that represents sealing device manufacturers, the Fluid Sealing Association (FSA) recognizes the importance of addressing this issue. Emissions of methane represent the waste of a valuable Canadian energy resource, with additional negative implications for the environment and local community air quality.

“The Fluid Sealing Association values the contribution this report makes in increasing understanding, both of Canadian oil and gas methane emissions and of the tremendous opportunities today for Canadian firms to tighten operations. We stand ready to help companies better control methane emissions, using the latest sealing device technology to reduce leaks,” said Mike Shorts, President of the Fluid Sealing Association and Vice President and General Manager of Triangle Fluid Controls, a Canada-based manufacturer of sealing products.

“As one of many service companies that work to capture methane emissions, this is an issue we can fix. Let’s keep methane where it belongs – in the pipe instead of the air.”

The FSA is well equipped to work with industry on emissions control solutions and is a technical resource for best available technologies for curtailing fugitive emissions. Member companies of the FSA represent an array of sealing technology solutions that can enable emission reductions across the Canadian oil and gas and process industry sectors.

Greenhouse Gas from Power Plants Declines

The U.S. EPA has released its third year of greenhouse gas (GHS) data detailing carbon emissions and trends from large facilities broken down by industrial sector, GHS, geographic region, and individual facility. The data, required to be collected annually by Congress, highlight a decrease in these emissions as more utilities switch to cleaner burning natural gas.

EPA’s Greenhouse Gas Reporting Program collects annual information from over 8,000 facilities in the largest emitting industries, including power plants, oil and gas production and refining, iron and steel mills, and landfills. In addition, the program is receiving data on the increasing production and consumption of hydrofluorocarbons (HFCs), predominantly used in refrigeration and air-conditioning. This Program is the only one that collects facility-level GHG data from major industrial sources across the U.S.

The 2012 data show that in the two years since reporting began, emissions from power plants have decreased 10%. This is due to a switch from coal to natural gas for electricity generation and a slight decrease in electricity production. Fossil-fuel fired power plants remain the largest source of U.S. GHG emissions. With just under 1,600 facilities emitting over 2 billion metric tons of CO2 in 2012, these plants account for roughly 40% of total U.S. carbon emissions.

The data are accessible through EPA’s online data publication tool, FLIGHT, which is available for both desktop and mobile devices. This year, with three years of data for most sources, FLIGHT now has been updated with new features, including the ability to view trend graphs by sector and facility as well as download charts and graphs for use in presentations and reports. The data are also published through EnviroFacts, which allows the public to download data for further analyses.
