About Us
Emission Technology Solutions was established to provide cost effective solutions to the emissions management demands of key US industries. Our mission is to provide technological solutions that facilitate and improve the workflow of our customers through automation and AI, while leveraging the innate and inherence intuition of all team members.
The demand for these technologies is tied to the objectives for safe and efficient processing, limiting lost production of both fugitive and non-fugitive emissions, and compliance towards a growing regulatory landscape.
The Clean Air act of 1963 has evolved over the past sixty years to encompass many aspects of air quality management, and more recently to encompass concerns of an imbalance in Greenhouse Gases.
To address these needs, Emission Technology Solutions offers technology evaluation services for companies seeking to improve their products or inspection solutions, and for compliance with many of these regulations, particularly those related to hydrocarbon gas emissions. As many of the emerging regulations involve the quantification of gas emissions, ETS has focused on the application of Optical Gas Imaging (OGI) technology as a cost-effective method for performing oil and gas facility inspections. More specifically, ETS has focused on enabling real time quantification of any emissions detected by the OGI camera.
Introducing PlumeQuant*
PlumeQuant is ETS’s software solution for performing analyses of OGI footage. The objective of the software is to increase the benefits of using OGI technology to perform inspections for emissions management. Inspects also become more efficient as it greatly reduces the burden for analyzing videos manually. This technology is particularly useful addressing regulatory requirements where empirical data is required for measuring emissions. These include the proposed revisions to Subpart w of the GHG regulations, and international standards such as OGMP 2.0. PlumeQuant can be used to analyze individual videos, multiple “batch mode” videos, or for real time analysis. This allows PlumeQuant to be used on mobile platforms such as ground robotics, drones, and hand-held cameras, as well as with continuous monitoring applications where the camera is gimballed onto a stationary mount.
Appendix K Evaluation – Influencing Factors
During 2022 and 2023, the EPA has been working with industry to develop the requirements for utilizing OGI technology on a broader class of assets. While the requirements are not yet finalized, ETS has chosen to work with the draft requirements to study the operating envelop(s) per Appendix K for one specific OGI camera from Sierra Olympia, using their Ventus OGI camera. The goal of the study is to develop the Operating Envelop of this camera around the minimum leakage requirements for the proposed EPA Appendix K. As shown below, the Operating Envelop is central to the overall inspection process.
Appendix K Evaluation – The Operating Envelop
The size of the Operating Envelop is a function of many things, some of which are inherent to the camera itself, such as the as the sensor resolution, NETF value, focal lengths, and enhancement modes to make emission plumes more visible, and many which are field condition dependent. The difficult aspect of staying within the operating envelop for operators is that many of the parameters impacting the envelop boundary are interconnected and are changing in near real time in the field. The videos below show some of the inherent camera features to increase camera sensitivity, and charts beneath showing the influence of DeltaT and Wind speed on the Probability of Detecting an emission.
Gas Behavior
Different hydrocarbon gases have different molecular weights, diffusion rates, and response factors to OGI. Here are a couple of comparison videos.
The ETS Team
ETS is a small team of dedicated engineers and computer scientist who are working to address the needs to measure and reduce emissions, both domestically and internationally. The PlumeQuant software utilizes the latest in AI based Computer Vision technology to detect emissions with few false indications of a leak, and to provide practical quantification values for a wide range of plume types and field conditions.
