  • Case study - Biogas desulfurization and siloxanes abatement

    MCFC project by CETAGUA (Mataró – Spain) Reducing the carbon footprint of our society is imperative. This can be achieved by capturing and confining anthropogenic CO2 emissions as well as by replacing fossil-based fuels with renewable or waste-derived fuels. MCFCs (Molten Carbonate Fuel Cells) are unique in being able to do both these things. Thanks to their operating ...

  • Siloxanes reactor - Siloxanes removal in municipal WWTP - Case Study

    Siloxanes - What are they? Siloxanes are a subgroup of silica compounds containing Si-O bonds with organic radicals attached to the silica molecule including methyl and ethyl groups, among others. These compounds are widely used in various industrial processes and are frequently added to consumer products (shampoos, toothpastes, lotions, paper products, paints, oils,...). ...

  • Contact Lens Permeation Testing from Systech Illinois

    A contact lens design using a particular material will require the measurement of Oxygen Permeation.  Materials with higher permeation rates together with thinner lenses will perform better, providing greater comfort during use.  However, simply choosing the material with the highest permeation rate and making the lens thin is not an easy option.  The lens shape and thickness ...

  • Behaviour and adsorptive removal of siloxanes in sewage sludge biogas

    We investigated the behaviour of siloxanes, which adversely affect biogas engines, as well as their concentration levels in sewage sludge biogas in Japan. We also performed experiments on the absorptive removal of siloxanes using various adsorbents and determined the main adsorbent characteristics required for the removal of siloxanes. The results of our study on the concentration and composition ...

  • A Summary of Available Analytical Methods for the Determination of Siloxanes in Biogas

    ABSTRACT The importance of measuring siloxanes has increased with the recent growth of the landfill-gas-to-energy (LFGTE) market. Siloxanes and other biogas impurities can form a residue upon combustion in engines that may increase maintenance and reduce engine lifetime.  A siloxanes analysis can assist with either determining if a bioaas purification system is needed, or if a system is ...

  • Comparison of Impinger and Canister Methods for the Determination of Siloxanes in Air

    Abstract Tliis paper compares canister and impinger methods for the analysis of siloxanes in air by gas chromatography/inass spectrometry (GC/MS). Siloxanes are frequently found in commercial and consume? products such as detergents and cosmetics. Most low molecular weight siloxane compounds volatize quickly into the atmosphere; however, some end up in wastewater or landfills when consumer ...

  • SPME/GC Analyses of Sulfur Gases and VOCs, Using a Carboxen/PDMS Fiber

    Sample extraction of sulfur compounds and VOCs by traditional methods can be difficult and expensive. Typically, sulfur analysis requires concentration of the gas using adsorbent tubes containing carbon adsorbents. Analysis by such means, however, requires the use of an expensive thermal desorption unit to heat the tubes before transferring the gases to a gas chromatograph. Analysis of VOCs ...
