    Steelmaking process monitoring by Direct MS

    Steel, an alloy of iron and carbon (up to 2% of weight), is one of the most widely used construction materials. It is produced by Basic Oxygen Steelmaking (BOS) in a converter : oxygen is blown to form carbon monoxide (CO) and carbon dioxide (CO2) with the carbon excess of molten pig iron. Other chemical elements (such as nitrogen) that may decrease the efficiency of furnace are also removed. Finally, oxygen is replaced by an inert gas (Ar) to minimize the oxidation.

  • Total Sulfur monitoring

    Total Sulfur includes all the gases described within total reduced sulfur, as well as sulfur dioxide as these compounds are oxidised forms of sulfur. Exposure to sulfur dioxides, and other reduced sulfur based compounds can cause many harmful effects in humans including headaches, general discomfort up to death in large doses. Those with impaired heart or lung function and asthmatics are at increased risk. Sulfur dioxide, one of the major pollutants, is absorbed by soils and plants and captured within and below...

    Online monitoring solutions for determination of moisture in dry chlorine

    The purpose of determination of moisture in dry chlorine is threefold: prevent corrosion, prevent formation of ferric chloride and control the overall drying process. AppliTek offers two different solutions for determination of moisture: one traditional method by means of an amperometric phosphoric pentoxide (P2O5) electrochemical cell, or a more advanced technique based on tunable diode laser technology (TLDS). Both analyzer systems are installed in a compact protective corrosion resistant cabinet.

  • Irrigation Water Chlorine Dioxide Treatment

    Irrigation Systems: A common problem encountered in all irrigation systems is growth of micro-organisms in the irrigation pipes causing poor flow, blockages and the potential for the spread of disease-causing organisms throughout the irrigated area, particularly fungal diseases. The micro-organisms flourishing in irrigation pipes include bacteria and fungi and, if sufficient light is present, algae. Irrigation pipes provide an ideal environment for the establishment of biofilm on the inside of the pipes.

  • Hospital Water Chlorine Dioxide Treatment

    In the normal course of operation, hospitals generate a variety of waste products which are not suitable for normal disposal. While some or most hospital waste may be harmless, it is difficult to distinguish such harmless waste from infectious waste. As a result, all of the waste from a hospital must be treated as if it is harmful.

    Monitoring solutions for the marine industry

    While land-based industry has been subject to strenuous emissions regulations over the past decades, air emissions from sea-going ships’ machinery has so far been largely unregulated. As a result, according to EU statistics, ships have become the single biggest source of sulphur dioxide (SO2) within the EU. The US EPA (US Environmental Protection Agency) reports similar findings, i.e., that the proportion of air pollutants released which can be attributed to the shipping industry is increasing.
