摘要： Treating carbon steel tubing includes contacting the carbon steel tubing with a first treatment solution including a salt; corroding the carbon steel tubing with the salt to yield a corroded surface on the carbon steel tubing; contacting the corroded surface on the carbon steel tubing with a second treatment solution comprising sulfide ions; and forming an iron sulfide layer on the corroded surface of the carbon steel tubing by chemically bonding the sulfide ions in the second treatment solution with iron in the carbon steel tubing. In some cases, the first treatment solution also includes sulfide ions, and the iron sulfide layer is formed by contacting the carbon steel tubing with the first treatment solution.

摘要： Some sensitive metal surfaces are often unable to be contacted effectively with hydrofluoric acid or acidic fluoride ions due to significant corrosion issues that may occur. Metal surfaces comprising titanium or a titanium alloy represent but one example of sensitive metal surfaces having this issue. Corrosion inhibitor compositions comprising boric acid and other boron-containing compounds may at least partially suppress corrosion of titanium and titanium alloy surfaces. Methods for suppressing corrosion may comprise: contacting a metal surface comprising titanium or a titanium alloy with a corrosion inhibitor composition comprising a boron-containing compound; and interacting the metal surface with a fluid phase comprising hydrofluoric acid or acidic fluoride ions.

摘要： Methods for inhibiting corrosion in aqueous evaporative systems where soluble silica (SiO2) is maintained at residuals between 10 Mg/L and saturation, but more preferably maintained at greater than 300 mg/L as SiO2, to provide corrosion inhibiting silica films that protect system metals. Silica is provided by evaporation of water and subsequent concentration and transformation of silica naturally contained in source water. The methods of the present invention provide highly effective inhibition of corrosion for mild steel, copper, stainless steel, aluminum, zinc, galvanized steel and various alloys of such metals. The methods of the present invention comprise pretreatment removal of polyvalent metal ions from the makeup source water, maintenance of concentration of monovalent metal ions, and controlling pH at a minimum of 7.0 in the presence of an elevated temperature aqueous environment. Thereafter, specified water chemistry residual ranges are maintained in the aqueous system to achieve inhibition of scale and corrosion.

摘要： A slag and corrosion control process is described. The process entails: identifying the location of at least one slagging problem area in a boiler; introducing a slag control chemical comprising magnesium oxide or hydroxide into combustion gases in a location identified as having a slagging problem; identifying the location of at least one corrosion problem area in a boiler; and introducing a corrosion control chemical comprising a sulfate salt, bisulfite salt, sulfuric acid, or sulfur into combustion gases in a location identified as having a corrosion problem. In operation, these slag deposits will be sufficiently friable to be removed by relatively moderate application of physical energy, thus saving time and reducing any damage to the tubes by the cleaning process. The slag deposits are less voluminous and less in weight and are removed quickly. It is an advantage of the invention that slag can be removed with little or no shut down of a boiler.

摘要： A corrosion control process is described. The process is especially useful in the control of chloride corrosion in waste to energy boilers. Corrosion of high temperature surfaces can be assessed by the monitor and controlled introduction of treatment chemicals by targeted in furnace injection reduces corrosion while maximizing combustion efficiency. A corrosion monitor is also described. Before and following selection of corrosion control chemicals and the locations for targeted in furnace injection, injection regimen and chemical selection and introduction parameters are monitored with the aid of the method and apparatus of the invention to adjust one or more control parameters to reduce corrosion. A preferred method will employ a treatment chemical that comprises an SO2 or SO3 reagent, e.g., sulfuric acid, sulfur, a sulfate salt or a bisulfite salt.
