...This paper presents the laboratory testing data for scale inhibitor evaluation under mimic field conditions of cooling tower, steam flood, and ASP applications. The tests not only conducted on silica/silicate control, the dispersancy for both iron oxide and zinc hydroxide were also studied by using...

...Abstract Silica scales are perhaps the most recalcitrant deposits in the water treatment industry. Silica scale control can be achieved either by silica removal or by chemical inhibitors. Our goal is the discovery, design and application of organic additives that have some effect on silica...

... reservoir. The total depth of the well is 4650 meters. Based on this a model is set up for temperature and pressure profile along the well. Knowledge gaps, such as lacking solubility data and corrosion rates at supercritical conditions are pointed out. Geothermal energy deep geothermal energy DGE silica...

...Silica scale formation is an intricately complex process. It is usually favored at a pH of less than 8.5, whereas magnesium silicate scale forms at a pH of more than 8.5. ¹⁴ Existing data reveal that silica solubility is essentially independent of pH in the range of 6 to 8. Silica...

... nor under deposit corrosion caused by iron deposit or hardness scale adhesion. This paper investigated iron deposition and hardness scale inhibition technologies for boiler water containing high concentrations of iron up to 30 mg Fe/L or silica up to 1,000 mg SiO₂/L in boiler water, which...

...silica scaling corrosion prediction monitoring INTRODUCTION Geothermal fluids derived from deep hot water-rock reservoirs contain dissolved solids, at the concentrations varying from about 100 mg/kg (Iceland) to about 250,000 mg/kg (Salton Sea). Utilization of produced waters after steam...

... of an inner scale, mainly consisting of silica, was responsible for the improved oxidation resistance. However, a substantial increase in oxidation rate due to the formation of molten eutectic fayalite (Fe₂SiO₄) was observed when the temperature was raised to 1200 °C. Under straining...

... biocide ozone silica yellow metal corrosion INTRODUCTION The use of ozone in cooling tower treatment has received a great deal of attention in recent years. There are a number of factors which give this concept a great deal of appeal to cooling tower users. They include: The purpose of this paper...
