  • Reasons and prevention of corrosion-induced failures of prestressing steel in concrete

    Serious damages in post- and pretensioned prestressed components have occurred due to hydrogen-induced stress corrosion cracking of prestressing steel. The failures happened due to onsite conditions and were favoured by the sensitivity of the steels towards hydrogen. The contribution describes the mechanism of the fracturing process, the corrosion testing of prestressing steel and gives an ...

  • Organics in boiler water condensate

    With the wide use of high efficiency boilers and current high-pressure boilers in industry today limiting condensate analysis to the more traditional parameters can result in very expensive repairs. Condensate return should be the highest quality least expensive water that most systems can generate. Boiler operators do not want to lose this or have it contaminated. Condensate return analysis has ...

  • Corrosion of Electronic Components by Hydrogen Fluoride

    Generation of hydrogen fluoride (HF) from fire suppression by some gaseous agents is a major concern, because HF causes corrosion. Without proper precautions, the HF corrosion damage to some electronic facilities can be significant. A study has been carried out to evaluate the corrosion effect of HF on electronic equipment. This article describes details of the corrosion study in terms of test ...

  • Case study - RTOs leave nothing to HAP-penstance

    PROBLEM The United States EPA promulgated a ruling in 40 CFR, imposing strict new standards to reduce emissions of toxic air pollutants from the manufacture of pharmaceutical products, including prescription and over-the-counter drugs. The agency's rule was intended to reduce emissions of a number of air toxins and hazardous air pollutants (HAPs), including methylene chloride, ...

  • Case study - Purified terephthalic acid plant

    Overview A major chemical manufacturer required a pollution control system to destroy the halogenated volatile organic compounds (VOCs) emitted during the formulation of Pure Terephthalic Acid (PTA). During the production process, methyl bromide is converted to hydrogen bromide. The pollution control system had to be designed to withstand the corrosiveness of the hydrogen bromide and ...

  • Case study - Engine cell exhaust: RTO

    Problem A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished the engines are removed from the assembly line and run for quality control.
