“…While storage tanks are known to be frequent emitters of CH4, 19 very little literature exists regarding true leak emission rates from oil and gas storage tanks due to the challenges associated with direct measurement of such leaks. 20 The release rates tested in this experiment are expected to be smaller than true emission rates from storage tanks and serve as an evaluation of the lower detection thresholds for the GreenLITE™ system.…”

The GreenLITE™ emission monitoring system detected, located, and quantified methane (CH4) emissions from a series of single-blind controlled releases with no prior knowledge of timing, locations, or release rates. System performance was evaluated against metrics defined in the Continuous Monitoring Protocol established by the Methane Emissions Technology Evaluation Center (METEC) at Colorado State University. This protocol allows more direct comparison of system performance between disparate measurement technologies. This experiment differs from similar tests where releases were conducted from equipment units at METEC by instead conducting releases at random locations anywhere within the central 0.18 km2 of a 0.35 km2 test site. The releases were much shorter in duration than those conducted in similar testing at METEC. GreenLITE™ detected 25 of 42 releases, which ranged in metered rate from 0.17 to 2.15 kg/h. The minimum detected emissions rate was 0.22 kg/h. GreenLITE™ demonstrated a 100% detection rate for releases ≥0.65 kg/h and average wind speed <5 m/s. The test site was subdivided into 20 boxes (109 × 83 m each), and the correct release box was identified in 9 cases, another 9 detections were localized to an adjacent box, and the remaining 7 were attributed elsewhere within the field. The average estimated emission rate bias was -6.1%. The 90% detection limit was 0.89 kg/h, while the wind-normalized detection limit was 0.44 (kg/h)/(m/s).

X merupakan perusahaan yang bergerak di bidang penyediaan listrik, terdapat berbagai peralatan yang diperlukan agar proses penyediaan listrik agar tetap berjalan lancar. Salah satu peralatan pendukung yang ada di PT.X adalah tangki timbun, yang merupakan peralatan pendukung sistem bahan bakar, yaitu sebagai tempat untuk menyimpan bahan bakar minyak High Speed Diesel. Pada hasil inspeksi daily tank 3 HSD oil terdapat ketebalan pelat minimum yang terbesar berada pada course 1 yaitu 3,1704 mm, dan corrosion rate yang terkecil pada course 2 dan 5 yaitu 0,02 mm/years untuk remaining life terkecil berada pada course 1 yaitu 80 years, berikut untuk mengetahui berapa persen dari kecukupan daily tank 3 HSD Oil, oleh karena itu didapatkan okupansi dengan nilai 11% jadi dari hasil inspeksi yang temui bahwa daily tank 3 HSD oil masih layak untuk di gunakan dalam jangka waktu yang lama.

“…Passive OGI cameras rely on infrared (IR) imaging of gas species with the most common type operating in the mid-wave spectrum (3 µm-5 µm)-the absorption spectral window of methane and other light hydrocarbons [13][14][15]. LDAR surveys with handheld OGI IR cameras require scanning equipment components at O&G facilities to identify emissions as demonstrated in several field measurement studies [16][17][18][19][20][21][22]. While recent, advanced emissions detection technologies that are based on drones [23,24], automobiles [25,26], and aircraft [27,28] promise faster surveys at a relatively lower cost, they cannot localize emitting components.…”

Quantitative optical gas imaging (QOGI) system can rapidly quantify leaks detected by optical gas imaging (OGI) cameras across the oil and gas supply chain. A comprehensive evaluation of the QOGI system’s quantification capability is needed for the successful adoption of the technology. This study conducted single-blind experiments to examine the quantification performance of the FLIR QL320 QOGI system under near-field conditions at a pseudo-realistic, outdoor, controlled testing facility that mimics upstream and midstream natural gas operations. The study completed 357 individual measurements across 26 controlled releases and 71 camera positions for release rates between 0.1 kg Ch4/h and 2.9 kg Ch4/h of compressed natural gas (which accounts for more than 90% of typical component-level leaks in several production facilities). The majority (75%) of measurements were within a quantification factor of 3 (quantification error of −67% to 200%) with individual errors between −90% and 831%, which reduced to −79% to +297% when the mean of estimates of the same controlled release from multiple camera positions was considered. Performance improved with increasing release rate, using clear sky as plume background, and at wind speeds ≤1 mph relative to other measurement conditions.
