Gas flaring is the controlled burning of natural gas and a common practice in oil/gas exploration, production and processing operations (EPA,2014). However, gas flaring can lead to an essential environmental concern as gas flaring may result in the release of substantial volumes of potent GHGs, including CO2, methane, black soot and nitrous oxide, into the atmosphere, contributing to air pollution and climate change.

A growing number of state and local governments are requiring operators from oil and gas industry to monitor and control gas flaring process, and also to measure and report the amount of vented gas, aiming to reduce the number of pollutants entering the atmosphere. For instance, in the USA, the EPA has implemented Title 30 CFR Part 250 Subpart K - Flaring, Venting, and Burning Hydrocarbons for gas metering and Title 40 CFR 63.670 Requirements for Flare Control Devices to control gas flaring emission.

To meet the growing demand for gas flaring control and monitoring in the gas and oil industry, Cubic has adopted diverse mature technology platforms of ultrasonic technology, tunable diode laser absorption spectroscopy (TDLAS), and Laser Raman technologies to develop effective gas flaring solutions, including gas sensors, gas analyzers and gas flow meters with the features of high accuracy and long-term stability.

Gas Flaring Process and Emission Monitoring

Gas metering in gas flaring is essential for accurately quantifying the volume of gas burned and emitted. It enables precise measurement of greenhouse gas emissions, aiding in compliance with regulations and facilitating emission reduction efforts. Additionally, it supports efficient resource management and financial accountability in the oil and gas industry.

Combustion Optimization During Gas Flaring Process

During the flaring process, gases such as methane, ethane, propane, butane, and hydrogen sulfide are typically measured to assess their composition in achieving combustion optimization during gas flaring. By continuously monitoring the composition of flared gases, timely adjustments to the air-to-fuel ratio can be made to ensure complete combustion and minimizing harmful byproduct. Moreover, data recording and gas composition analysis enable trend identification for ongoing combustion, ensuring continuous optimization, reduced emissions, and adherence to regulatory standards.

GHG Emission Monitoring After Gas Flaring

Gas flaring is one major source accounting for greenhouse gas emission in oil and gas industry. After gas flaring, combustion byproducts such as carbon dioxide, carbon monoxide, nitrogen oxides, particulate matter, and volatile organic compounds may be vented, which should be monitored to evaluate combustion efficiency and environmental impact. Also, gas flaring may release methane, as incomplete combustion during flaring produces methane, or an active flare may be not totally extinguished, resulting in the direct venting of methane gas to the atmosphere that should be combusted. It is essential to measure and monitor vented methane gas under safety concern.
