Green House Gas (GHG) Reporting Rules Require Innovative Mass Flow Measuring Methods

FOR IMMEDIATE RELEASE
Pacific Grove, California, United States of America (Free-Press-Release.com) October 4, 2011 -- New Green House Gas (GHG) Reporting Rule Affects a Wide Variety of Industries and requires the development of innovative and optimally designed Boiler Mass Flow Meters.

In 2011, a new rule from the Environmental Protection Agency (EPA) (40 CFR Part 98) went into effect requiring many fossil fuel suppliers, industrial gas suppliers, manufacturers of vehicles and engines outside of the light-duty sector and certain down-stream facilities that emit greenhouse gases to submit annual reports to the EPA.

Green House Gas (GHG) Reporting Rules Require Innovative Mass Flow Measuring Methods

In order to measure these mass flows the industry needed to procure an optimally designed boiler flow meter capable of measuring the flow rate of the boiler exhaust in accordance with the new rule.
Using classical orifice plates or turbine meters to measure these flows created significant and undesirable pressure drops as well as not being able to meet the strict requirements of the new rule. A discovery by the industry was to use a thermal mass flow meter, MFM, configured as a boiler mass flow meter that offer little or no measurable pressure drop is required in order to measure the flow. This type of MFM afforded the desired characteristics as well as having the capability to meet the requirements of the new rule.

Companies affected are primarily large facilities emitting 25,000 metric tons of carbon dioxide equivalent (mtCO2e) or more of GHG emissions per year.
The GHG's covered by the new rule are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorochemicals (PFC), and sulfur hexafluoride (SF6), as well as other fluorinated gases (e.g., nitrogen trifluoride and hydrofluorinated ethers). These emission of these gases are often expressed in metric tons of carbon dioxide equivalent (mtCO2e).

The 25,000 mtCO2e limit was chosen because it is estimated that 80% of the CO2 emitted comes from the 10,000 or so facilities that emit that much or more. 25,000 mtCO2e is equivalent to the annual greenhouse gas emissions from approximately 4,600 passenger vehicles consuming over 58,000 barrels of oil.
In other words, these emissions are represented mostly by big industrial facilities. 80% of the 10,000 facilities that will be affected are from the following categories:

» 3,000 Big combustion boilers/kilns/heaters (more than 30 million BTU's)
» 2,551 Landfills
» 1,502 Natural gas plants
» 1,108 Electrical generating stations
» 2,000 Paper mills, auto plants, refineries, bulk gas companies, steel plants and other metal production plants

For the industry to be able to measure the flows of the gases, as required by GHG legislation, users needed a MFM that was specifically designed to meet the needs of the GHG reporting rules that require an accurate measurement of the mass flow rate. The major discovery was that the use of thermal mass flow meters configured as boiler flow meters offeres the ideal solution.

» Direct flow monitoring will eliminate the need for separate temperature and pressure inputs
» Optimized for methane (CH4) as well as N20, SF6, HFCs, PFCs and CO2, per the EPA mandate
» 100:1 turndown can accurately measure both low and high flows
» A flow measuring system that requires no moving parts that prevents clogging and lowers maintenance costs

Dave Korpi has worked closely with many Green House Gas plants to upgrade the mass flow measuring systems by using the Sierra Boiler Trak line of immersible thermal mass flow meters.

Replacing dP devices with the Sierra Boiler Trak line of immersible thermal mass flow meters has saved these companies millions of dollars per year and reduces the CO2 emissions at the same time.
