  • Why Air Quality Specialists Should Measure for Sulfur Dioxide (SO2) in Homes & Offices - Case study

    What is Sulfur Dioxide? (SO2) Sulfur Dioxide (SO2) is a highly reactive gas that is part of a larger group of sulfur oxides or SOx gases. According to the U.S. Environmental Protection Agency, the largest sources of SO2 emissions are due to “fossil fuel combustion at power plants (73%) and other industrial facilities ...

  • Downstream sulfuric acid plants benefit from WESP technology

    Industrial-grade sulfuric acid, still the most widely used industrial chemical in the world, continues to be sourced primarily (about 70 percent) as a nondiscretionary byproduct from the roasting, smelting, and refining of nonferrous metals. The rest comes from natural gas processing, electric power generation, and spent acid regeneration. These industries are usually heavy emitters of ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Case study - N°AA4 – Ambiant air monitoring – WWP TRS MEDOR Stripping

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® ...

  • Fenton degradation of Cartap hydrochloride: identification of the main intermediates and the degradation pathway

    The advanced oxidation of Cartap hydrochloride (Cartap) promoted by the Fenton system in an aqueous medium was investigated. Based on total organic carbon, chemical oxygen demand and high-performance liquid chromatography, the oxidation of Cartap is quite efficient by the Fenton system. Its long chain is easily destroyed, but the reaction does not proceed to complete mineralization. Ion ...

  • Control of malodors using Ecosorb - A natural product

    Abstract Ecosorb removes many malodors, including sulfur dioxide, hydrogen sulfide and ammonia, from the environment. It is made up of a combination of essential oils consisting of an equilibrium of neutral organic compounds and organic buffers. Its pH ranges from 4.0 to 6.8. Acidic malodors such as hydrogen sulfide and sulfur dioxide are removed by at least four mechanisms ...

  • Measuring SO2 ship emissions with an ultraviolet imaging camera

    Over the last few years fast-sampling ultraviolet (UV) imaging cameras have been developed for use in measuring SO2 emissions from industrial sources (e.g. power plants; typical emission rates ~ 1–10 kg s−1) and natural sources (e.g. volcanoes; typical emission rates ~ 10–100 kg s−1). Generally, measurements have been made from sources rich in SO2 with high concentrations ...
