A preview on new flare system VOC regulations in the US covers flare system emission tests sponsored by the Texas Commission on Environmental Quality; steam assist type flare systems for smokeless control; detecting flare VOC emissions; and retrofit and new flare system design control options for VOC reduction, where flare system owners can best determine their method for control to meet the regulations. This is an abstract of a paper presented at the 2011 AIChE Spring Meeting & 7th Global Congress on Process Safety (Chicago, IL 3/13-17/2011). Source

In a 2012 report by the EPA's Flare Review Panel, regulations for flares that tended to operate outside their stable flame envelope were expanded to include limits on velocity as a function of net heating value. EPA regulations do not currently allow sonic velocity flares to be permitted and operated without first performing an alternate means of emissions limitation test to validate destruction efficiencies. Existing regulations affect the application of multi-point staged flares since these flares operate at sonic exit velocities that exceed the maximum exit velocity requirements cited in 40 CFR 60.18 and 40 CFR 63.11(b) and applicable state regulations. Over the years, Zeeco has conducted numerous destruction efficiency tests on its multi-point sonic flares. All of these tests demonstrated high destruction efficiency at velocities exceeding the EPA's limits. The purpose of these tests, performed at Zeeco's industrial-scale combustion test facility near Tulsa, Oklahoma, was to validate sonic tips for more applications using an expanded range of gases and conditions. Extractive sampling was used to measure the emissions from the exhaust plume at staging and de-staging pressures. The extracted gas concentrations were used to calculate the destruction efficiency of the multi-point sonic flare tips at each test point. Even with sonic gas exit velocities, the Zeeco-designed sonic flare tips maintained high destruction efficiency. Despite pressure from both end users and regulators, Zeeco's flare burner tests and results have been maintained internally. This paper will present those results to the industry for the first time. © Copyright 2015 Zeeco, Inc. Source

The new 2012 EPA Oil and Natural Gas Air pollution standards, enacted April 17, 2012, are designed to reduce harmful emissions of VOCs from hydraulically fractured wells. VOCs in the presence of sunlight promote the formation of smog (grade-level ozone) near areas where oil and gas production occurs. The four-targeted areas of VOC reduction in oil and gas production will affect some 25,000 wells per year as well as storage tanks and other processing equipment. Flare systems are proposed as one of the preferred control devices to meet these new regulations. Complicating the hydraulic fracturing production picture further, the industry expects new EPA flare regulations to be proposed shortly. These regulations are currently under review with public comment underway via the TCEQ and EPA Flare Stakeholder Task Force. This paper will address specifics of both new regulations and provide guidance for cost-efficient and effective flare system designs. Copyright 2012, Society of Petroleum Engineers. Source

Proceedings, Annual Convention - Gas Processors Association | Year: 2014
On April 17, 2012, following an eight year review process of the Clean Air Act, the U.S. EPA finalized and issued the first federally enforceable air quality regulations and standards for the Oil and Natural Gas Industry. These regulations and standards were designed to reduce emissions of smog-forming volatile organic compounds (VOCs), along with other Hazardous Air Pollutants (HAPs). After final comments of the newly proposed regulations were considered, the EPA released the New Source Performance Standards 40 CFR, Part 60, Subpart OOOO (NSPS 0000 or NSPS 40) and updates to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) 40 CFR, Part 63, Subparts HH, and HHH (HH/HHH) for the oil and gas production, transmission, distribution, and processing industries. These regulations originally published on August 16, 2012 in the Federal Register. The most recent revisions to the NSPS 0000 regulations were published in the Federal Register on September 23, 2013 (FR 58416). These revisions addressed the first round of petitions filed by the American Petroleum Institute (API) and others for reconsideration; however, this revision mostly addressed the questions surrounding storage tanks and the control device provisions of the rule. The EPA is expecting that all affected facilities comply with these regulations by installing a combustion control device that meets a 95% reduction. This applies to both HAPs and VOC emissions from hydraulically fractured gas wells, storage tanks, transmission, transportation, and processing equipment in the U.S. Oil and Natural Gas Industry. Flare systems, vapor recovery units, and enclosed combustors are the most common types of control devices that can be installed to meet the requirements of these new regulations. Ms. Blake Leary of Zeeco, Inc., in conjunction with Mr. Ron M. Clark, P.E. of Sage Environmental Consulting, L.P., will address the specifics of these new regulations, and provide guidance for upstream and midstream owners and operators in selecting the most cost-efficient and effective control systems available to meet these requirements.

A burner apparatus for a furnace system and a method of burner operation. The burner has a series of fuel ejection structures which at least partially surround the burner wall for ejecting fuel into a combustion region projecting from the forward end of the burner wall. The ejection structures preferably eject fuel outside of the burner wall at alternating angles. Further, the burner apparatus preferably includes at least one additional series of fuel ejection structures which is spaced radially outward from the first series of ejection structures.
