Bisulfite reaction with oxygen
WebApr 15, 2024 · ABSTRACT. Sodium bisulfite (SBS) oxygen scavenger is being applied in several sea water flood injection systems in the Gulf of Mexico. High corrosion rates (CRs) were observed in one particular field during periods when oxygen scavenger injection rates were elevated. In an effort to establish a safe operating concentration for oxygen … WebCatalyzed sodium sulfite is commonly used at 5 to 15ppm in the feedwater to ensure instantaneous removal of oxygen in a preboiler system, particularly where an economizer is involved. ... Most of the sodium sulfite is converted to sodium bisulfite by reaction with SO 2, as in the dual alkali process. Some of the sodium sulfite is oxidized to ...

WebAug 16, 2003 · reaction in which, the oxygen radical removes a hydrogen from the fatty acid, which leaves a carbon-centered radical within the fatty acid, which then reacts with oxygen to produce a peroxy radical, which can then react with other fatty acids or proteins. The process of lipid peroxidation is illustrated in Figure 1. Webintroduced. This oxygen may be controlled by feeding sodium sulfite in quantities sufficient to react with the oxygen and, in addition, adding enough to constitute a …
WebBisulfite-mediated conversion of cytosine (C) to uracil (U) occurs in three steps. The first step is the addition of bisulfite to C. This reaction occurs at acid pH. The second step is the deamination of cytidine–bisulfite (C-SO 3 −) to produce uracil–bisulfite (U-SO 3 −), which is optimal at a pH of 5 to 6. WebWith an excess of sulfite present (10 Na/sub 2/SO/sub 3//1 O/sub 2/, molar), 95% of the oxygen is removed at 100 deg F in 10 sec. At 200 and 300 deg F, oxygen removal is …
WebOxidation by atmospheric oxygen is the preferred reaction, but requires a suitable catalyst. Nickel is the most potent and thereby cheapest catalyst for this purpose. One Mg/L nickel in the cooling water would allow 99% removal of hydrogen sulfide to be attained. A major drawback of catalytic air oxidation is that colloidal sulfur is a major ... http://www.oilfieldwiki.com/wiki/Oxygen_scavenger#:~:text=The%20reaction%20of%20bisulfite%20with%20oxygen%20is%20typically,by%20transition%20metal%20ion%20catalysts%2C%20e.g.%20Cobalt%20%28II%29.
