Breakdown of Oxide Films on Steel Exposed to Chloride Solutions

Abstract: Breakdown of the thin air-formed oxide film is the first step in the corrosion of steel exposed to aqueous chloride environments. We studied oxide-film breakdown by observing changes, with time, of appearance, weight loss, and corrosion potential while varying the three components of the system: environment, substrate, and film. Environment was varied by changes in chloride and hydrogen peroxide concentrations. Low carbon steel, stainless steel, aluminum, and titanium substrates were studied. Various types of crystalline oxide film were applied to steel substrates by RF sputtering. The results of this work demonstrated that the chemical and electronic properties of the oxide film on steel are inconsequential in determining whether film-breakdown will occur. We interpret these results in terms of a film-breakdown mechanism in which substrate dissolution begins at film defects and spreads, thus causing removal of the film by undercutting. According to this model, the ability of the substrate to spo...

Removal of naphthalene from recirculated wash oil

Abstract: A bleed stream from the recirculating wash oil in a final cooling system for coke oven gas is centrifugally separated into a waste water stream, a sludge stream and a clean, dry oil stream which is substantially free of solids and has a water content less than 0.5% (wt.). The clean, dry oil stream is heated to less than about 160° C., preferably 125°-135° C., before entering a naphthalene stripper-wash oil still.

Method of shrinking collars on a shaft

Abstract: Method and apparatus for shrinking a metallic collar onto a shaft, with means provided for applying a coolant to the circumference of the collar while maintaining pressure thereon.

Process for direct cooling of corrosive industrial cases

Abstract: A method of direct cooling of hot corrosive industrial gases, particularly coke oven gas, is achieved by cooling of the gases by direct countercurrent contact with a liquid coolant such that the exit temperature of the coolant is raised to a temperature at which absorption therein of corrosive amounts of acid gases is prevented.
