  • Controlling Fugitive Emissions, Part 1: Close Capture Hooding

    Fugitive emissions, in their simplest form, are the uncontrolled release of gases to the atmosphere. Each one of us may contribute fugitive emissions when we fill our automobile gas tanks. The displacement of air inside the gas tank causes gasoline vapor emissions (hydrocarbons) to exit out the fill spout (un-controlled) to ...

  • 99% of Interceptor contamination remediated - Case study

    What is an Interceptor Tank? An interceptor tank is a trap used to filter out hydrocarbon pollutants from rainwater runoff. It is typically used in road construction and on petrol station forecourts to prevent fuel contamination of the water table via runoff. Petrol interceptors work on the premise that some hydrocarbons such as petrol and diesel float on the ...

  • Renaissance of paper models and folded plate structures in glass

    This paper presents the development of glass folded plate structures. Glass will not only be used as a transparent covering but as a load-bearing element for the whole structure. A complete outline ranging from the architectural approach including simple paper models to structural analysis will be presented. The structural concept and its functional characteristics will be confirmed by finite ...

  • Oxidation v. reduction: how to decide?

    Is in-situ chemical oxidation (ISCO) or in-situ chemical reduction (ISCR) the best option for your site? What factors should be considered to make such a decision? Many chlorinated hydrocarbon compounds (CHCs) can be degraded via oxidative or reductive processes. Accordingly, various ISCO technologies using oxidizing agents such as hydrogen peroxide (Fenton’s chemistry), permanganate, ozone or ...

  • A folded wedge model for determination of true stratigraphic thickness in directional wells

    For exploration and development the geologists and engineers try to know the true stratigraphic thickness (t). The monoclinal and folded bed models are published methods for t calculation. Both models assume parallel beds which can lead to significant deviations. In order to calculate the values of t considering the effects of both folding and stratigraphic variation we propose the 'folded wedge ...
