  • QuadOa and OGI: how EPA regulations are changing the way we look at gas leaks

    Earlier this year, the Environmental Protection Agency (EPA) published Regulation 40 CFR, Part 60, Sub-part OOOOa, commonly known as Quad Oa, and finally brought optical gas imaging (OGI) firmly into the mainstream. This presents a major shift in the way fugitive emissions are regulated, and the technology that can be used.  Detecting and acting on gas leaks is naturally a major ...

  • Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy

    At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to ...

  • Gas Monitor Bump Testing vs Calibration

    We are often asked to explain the difference between calibrations and bump testing. This is a controversial subject. OHS would have you do a full calibration before each use. In practice, our customers come up with their own intervals. If the gas monitor is used infrequently, say once a month, it should be calibrated every time to give you confidence that the unit is going to respond as it ...

  • Detection and measurement of toxic gases from destructive testing of batteries

    Problem Statement New formulations of organic-compound-based batteries for vehicle use must be tested for release of potentially harmful and toxic gases if crushed in accidents. Potential gases include hydrocarbons, fluorocarbons, and hydrogen fluoride, released within seconds of an incident. Actual time-resolved and quantitative data are required from destructive testing to ascertain ...

  • Comparison of three global optimization algorithms for calibration of the Xinanjiang model parameters

    The Xinanjiang model, a conceptual rainfall-runoff (CRR) model with distributed parameters, has been successfully and widely applied to flood forecasting of large basins in humid and semi-humid regions of China. With an increasing demand for timely and accurate forecasts in hydrology, how to obtain more appropriate parameters for CRR models has long been an important topic. These models have a ...

  • CFD modelling of sampling locations for early detection of spontaneous combustion in long–wall gob areas

    In this study, computational fluid dynamics (CFD) modelling was conducted to optimise gas sampling locations for the early detection of spontaneous heating in longwall gob areas. Initial simulations were carried out to predict carbon monoxide (CO) concentrations at various regulators in the gob using a bleeder ventilation system. Measured CO concentration values at these regulators were then used ...
