Previously, precipitation of SI and Ca2+ was investigated. Similar work has also been performed by other researchers. The current paper presents corresponding experimental results where the binding of divalent cations Ca2+ and Sr2+ to 9 phosphonate SIs at pH 8.5, 95oC is investigated.

Moisture Vapor Emission Rates of Concrete Floors – Can Moisture Meters be used Instead of Calcium Chloride?

Product Number: 41212-666-SG

Author: George Holz, Kevin Brown

Publication Date: 2012

$20.00

The moisture vapor emission rate (MVER) of concrete floors affects the selection of flooring materials for both new construction and remodel projects. The MVER is determined by exposing a 20” x 20” test area to calcium chloride for 60 to 72 hours.

Optimization of FGD Operating Conditions by Electrochemical Laboratory Testing Applied to Alloy UNS S32205

Flue gas desulfurization (FGD) systems are frequently used at power plants to remove SO2 from coal combustion. In systems where limestone is utilized, calcium sulfate from the resulting slurry can be concentrated into a valuable byproduct. However, the concentrated slurry containing chloride poses increased localized corrosion risk to the materials of construction in contact with exhaust/combustion stream. Cyclic Potentiodynamic Polarization (CPP) and Critical Crevice Temperature (CCT) present electrochemical methodologies which can be used to assess the relative risk of different conditions in the laboratory. However, the results of these techniques can be dependent on the details of the experimental protocol. In this study, the effect of slurry preparation, potential scan rate, alloy conditioning time, and slurry acidity were examined. A conservative test protocol was developed based on the outcomes of the effects considered, and the critical chloride concentration of Alloy UNS S32205 was determined, enabling optimization of FGD operating conditions.

Simulating Corrosion And Scale Interactions In Autoclave Experiments: A Sensitivity Study

Product Number: 51322-17622-SG

Author: Robert Jacklin, Joshua Owen, Danny Burkle, Anne Neville, Richard C. Woollam, Richard C. Woollam

Publication Date: 2022

$20.00

Carbon dioxide (CO₂) saturated brines containing high levels of calcium are commonly encountered across the energy sector: from hydrocarbon recovery to the harvesting of geothermal energy and re-deposition of CO₂ for permanent storage. These brines originate in deep underground reservoirs at elevated pressures and temperatures. Despite susceptibility to corrosive attack under these conditions, carbon steels are the preferred choice of pipeline materials for such processes, attributable to their low cost, availability and ease of manufacture.

The Effect of Dissolved Calcium on Sour Corrosion

Product Number: 51323-19060-SG

Author: Jon Kvarekvål, Gaute Svenningsen, Marion Seiersten

Publication Date: 2023

$20.00

A large part of the remaining natural gas reserves worldwide is sour, i.e. H2S-containing. Many oil and gas fields, especially in North America, Central Asia and the Middle East, are highly sour with an H2S fraction of several percent. Internal corrosion in sour environments is associated with a high risk of severe localized corrosion attacks.
