Greenhouse gas monitoring for regulations and compliance consultancy - Environmental - Environmental Regulations and Compliance

Kurz thermal mass flow meters exceed the certification levels required by the Mandatory GHG Reporting regulation and are approved for these applications.

On September 22, 2009, the U.S. Environmental Protection Agency (EPA) signed a new rule requiring facilities to begin reporting GHG emission, starting with the year 2010. The EPA announced that:

'Under the rule, suppliers of fossil fuels or industrial greenhouse gases, manufacturers of vehicles and engines, and facilities that emit 25,000 metric tons or more per year of GHG emissions are required to submit annual reports to EPA. The gases covered by the proposed rule are carbon dioxide (C02), methane (CH4), nitrous oxide (N20), hydrofluorocar-bons (HFC), perfiuorocarbons (PFC), sulfur hexafluoride (SF6), and other fluorinated gases including nitrogen trifiuoride (NF3) and hydrofluorinated ethers (HFE).'

The EPA estimates that under this rule over 10,000 facilities will be required to report. Affected facilities will have to monitor parameters necessary to determine the Greenhouse Gas emissions from the facility. Depending on the facility and process, this may include the monitoring of fuel flows, process streams and/or stack flows.

The GHG Regulation requires flow to be determined by mass, not volume. Pressure differential devices (orifice plates, pitot tubes), turbine meters, vortex meters, and ultrasonic meters measure volume, not mass.Accordingly, those devices that measure volume will also require measurement of other parameters such as pressure, temperature and gas density in order to calculate mass flow, so additional costs for those measurement instruments will be necessary.

Mass Flow Meters measure mass directly and can provide continuous realtime monitoring over a broad range of temperature, pressure and gas density without requiring the additional, costly measurement instrumentation needed for volumetric meters.
