  • Rehabilitation of Hydrogen Grooving in Sulfuric Acid Line

    Around October 2001, one of the major petrochemical refineries located on the Texas Louisiana Gulf coast needed to rehabilitate 6' and 8” diameter “fresh acid” (98% sulfuric acid) lines. Such lines tend to suffer from internal gouging due to formation of hydrogen gas in voids, which are caused by turbulence at directional changes in the pipe flow such as elbows, etc. This is a natural event, ...

  • Power plants use oil skimmers to prevent contamination from spills

    Most hydroelectric plants designed in the 1960s were built with a station drainage sump that collects all drainage from the plant. As designed, float switches activate sump pumps that discharge liquids directly into the tailrace. The system cannot distinguish between types of liquids, so in the event of an oil leak, oil in the sump could be released into the tailrace. Modern ...

  • Evaluation of The Efficiency of Various Commercial Products for The Bioremediation of Hydrocarbon Contaminated Soil

    Bioremediation has become an important method for the treatment of terrestrial oil spills and is often favoured over strictly physical-chemical methods. In this study, enzymatic analyses and signature lipid biomarkers were employed to evaluate the efficacy of selected bioremediation products on control and oil contaminated soil plots. It is envisioned that these biological indicators may be used ...

  • Emulsan analysis produced by locally isolated bacteria and acinetobacter calcoaceticus rag-1

    Emulsifiers are widely used in industry, e.g., in medical and cosmetic products and in food systems. They can be used as agents to combat oil spills on beaches and in the sea. The materials that are currently in use commercially as emulsifiers are mainly produced by chemical synthesis. There is a great interest in studying bioemulsiflers because they have some advantages, such as theft ...
