The scavenging remained almost same even on increasing the duration of the action for 8, 16 and 24 hours. As compared to the oxygen removal by mechanical de-aerator of 30 and 49% at 30 and 75°C, respectively, and cobalt chloride of 38 and 66%, the sodium sulfite is similar in its action to the cobalt chloride.

Physical removal of the bulk of the oxygen is commonly used because it is much less costly than chemical removal alone. Although a properly operated deaerator can effectively remove oxygen to as low as 5 ppb, that level is still enough to cause significant damage in a boiler system.
Sodium erythorbate (C 6 H 7 NaO 6) is a food additive used predominantly in meats, poultry, and soft drinks. Chemically, it is the sodium salt of erythorbic acid. When used in processed meat such as hot dogs and beef sticks, it increases the rate at which nitrite reduces to nitric oxide, thus facilitating a faster cure and retaining the pink .
KT 342 is an specialty aqueous blend of erythorbate oxygen scavengers. It is designed for boiler steam plants where separate and independent feed of oxygen control is utilized. It is an industrial strength formula, designed for use in industrial and food processing plants. Ag Canada pending. Full tech data on this product . Product code: 7347
Is Erythorbate In Hot Dogs Really Earthworms Daniel Peng If you have ever read the ingredients label of various hamburgers or hotdogs, you may have noticed an ingredient name sodium erythorbate .
Oxidation And Degradation Products Of Common Oxygen Scavengers By John D. Zupanovich, ChemTreat, Inc. For many years, sulfite and hydrazine were the principal materials used to protect boiler systems from oxygen attack. When hydrazine became listed as a suspected carcinogen, a search began for a replacement.
Erythorbic acid and its sodium salt can replace Sodium sulfite and Hydrazine as oxygen scavengers. Sodium Erythorbate is a non toxic oxygen scavenger that can also be used in food processing systems. Adding Scavenger Chemicals. For best performance the chemical should be added in the storage tank before the feed tank. The efficiency of a scavenger is increased with longer …
(2) is the oxygen concentration on time (t) in days, and k is the kinetic constant. The order of the reaction can be chosen amongst the real numbers including zero. USP grade sodium erythorbate (E-316) with concentration 98% (Tecnas S.A.) and industrial grade iron sulphate …
As a rule-of-thumb dose 20 mg/L of scavenger in excess to the stoichiometric requirement. Let us consider an example of 45% by weight ammonium bisulfite solution used as an oxygen scavenger. If 10,000 Liter of water containing 8 mg/L oxygen is to be treated with this solution then what would be the quantity of 45% ammonium bisulfite required.
