Advancements in Bottom-Up Quantification of Fugitive Emissions using Optical Gas Imaging

The rising demand for quantifying leaks and emissions of methane and volatile organic compounds (VOCs), in terms of emission rate, raised the question of whether quantification-optical-gas-imaging (QOGI) software was capable of estimating emission rates remotely and accurately. This article describes, in detail, the science and calibration procedures of a quantification approach. ...

Optical Gas Imaging (OGI) Sensitivity Study

Introduction The traditional method 21-based Leak Detection and Repair (LDAR) program quantifies leaks in volumetric concentration units (ppm v). Leak detection with Optical Gas Imaging (OGI) ...

Monitoring Volcanoes Gas Emissions to Predict Volcanic Activity

Monitoring Volcanoes To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope ...
