Sage Metering has recently released “Flare Gas and 40 CFR 60 Subpart OOOO: Storage Vessels Approaching Quad O Deadline” which is an addendum to an earlier white paper. The earlier paper is “Flare Gas Measurement Using Thermal Mass Flow Meters,” dated July 2013.
Flare Gas Measurement Using Thermal Flow Meters
A 2013 white paper by Bob Steinberg reveals how flare gas and vent gas systems protect people and the environment by burning off waste gases and disposing of surplus gases. Flare gas systems are in many operations including oil and gas production, chemical processing, refining, wastewater treatment facilities, gas plants, and landfills. The measuring and monitoring of flare gas ensure the combustion device is operating correctly.
Also, stringent regulations often require measuring flare gas to the atmosphere. The earlier publication reveals the inherent challenges related to measuring and monitoring flare gas, such as the potential for changing gas composition, substantial flow variation, and working in hazardous locations. The paper shares how thermal mass flowmeters offer solutions for flare gas measurement and monitoring in various applications.
There are regulations worldwide providing guidelines for the operation of combustion devices. In the United States, the EPA requires the reporting of flare gas emitted to the atmosphere. That directive is the Mandatory Reporting of Greenhouse Gases Rule EPA 40 CFR 98.
The initial paper can be viewed online at Flare Gas Measurement.
Storage Vessels Approaching Quad O Deadline
EPA 40 CFR 60 encompasses the standards of performance for new stationary sources, and Subpart OOOO applies to rules involving crude oil and natural gas production, transmission, and distribution. Subpart OOOO is also known as Quad O. Quad O is the directive that includes emission standards and compliance timetables for the reduction of VOC and SO2 emissions from facilities that began construction or had alterations or renovations, after August 23, 2011.
For storage tanks emitting six tons per year of volatile organic compounds, the EPA requires a recovery system or combustion device to remove the VOC emissions. The combustion device is being recognized as the most predominant tool to burn off the VOCs. In this case, a continuous control monitoring mechanism is required to meet Quad O compliance. The EPA deadline for Quad O compliance for Group 1 storage vessels built between August 2011 and April 2013 is April 15, 2015.
The Sage thermal mass meter is ideal to meet those needs for continuous control devices. To read this addendum to the July 2013 white paper, visit Flare Gas Measurement Using Sage Thermal Mass Flow Meters.
