Corrosion of Iron in Hot Concentration Caustic Soda Solution

Pneumothorax following inhalation of caustic soda fumes.

new family home. He accidentally leant over the bucket and inhaled the fumes produced by the solution. Five minutes after the inhalation, he developed persistent pleuritic, right-sided chest pain and breathlessness. There was no personal or family history of pulmonary disease, and he had never smoked. Physical abnormalities were confined to the chest. He had a respiratory rate of 30 a minute an...

Regeneration of Caustic Soda Etch Solutions for Aluminum

A system for the regeneratlon of caustic soda solutlons used In etching aluminum Invokes the hydrolysis of sodium aluminate to llberate free sodium hydroxide and produce a dry, crystalllne hydrated alumlna byproduct. The system has been used extenslvely In Japan, and, by adjusting process parameters, can be adapted to North American practice. By otlllting the system in a typical plant, soild ai...

Hot Corrosion in Gas Turbines

DURING COMBUSTION in the gas turbine, sulfur from the fuel reacts with sodium chloride from ingested air at elevated temperatures to form sodium sulfate. The sodium sulfate then deposits on the hot-section components, such as nozzle guide vanes and rotor blades, resulting in accelerated oxidation (or sulfidation) attack. This is commonly referred to as “hot corrosion.” Sulfur in the fuel is gen...

A Study of Caustic Corrosion of Carbon Steel Waste Tanks

Solution chemistry of wastes from US atomic weapons production is controlled to inhibit corrosion of carbon steel tanks used in containment and storage. The pH, nitrate ion and nitrite ion concentrations of fresh solutions are maintained within specified limits for this purpose. In the start up process for a new waste evaporator (RHLWE), non-radioactive solutions of similar chemistry will be ci...
