WebNov 1, 2024 · In this paper, the kinetics of scale formation and its inhibition are studied using a conventional bottle test, a dynamic tube blocking rig and a recently developed in-situ flow visualization rig. Calcium carbonate scaling brine was prepared at two saturation indices (SI) of 2.1 and 2.8 at 50 °C and run through the rigs at flow rate of 20 ml/min.
WebThe COVID-19 epidemic has spread worldwide, infected more than 0.6 billion people, and led to about 6 million deaths. Conducting large-scale COVID-19 nucleic acid testing is an effective measure to cut off the transmission chain of the COVID-19 epidemic, but it calls for deploying numerous nucleic acid testing sites effectively. In this study, we aim to … WebApr 13, 2024 · Landslide susceptibility assessment using machine learning models is a popular and consolidated approach worldwide. The main constraint of susceptibility maps is that they are not adequate for temporal assessments: they are generated from static predisposing factors, allowing only a spatial prediction of landslides. Recently, some …
WebApr 1, 2011 · Inhibitors can work to prevent the catastrophic buildup of scale at three separate stages: the nucleation stage, the growth stage and the deposition stage. At the nucleation stage, threshhold inhibitors bind with scale-forming ions, but unlike chelants, the bound ions must be available to interact with their counterions. WebSep 8, 2024 · Reduction or prevention of scaling is commonly achieved by injecting scaling inhibitors into the geothermal circuit. Inhibitor-efficiency tests can be carried out in static or dynamic experiment set-ups allowing measurements at high pressures and high temperatures (HPHT). For these measurements, suitable analytical methods have to be …
