    Raw-gas monitoring for scrubber optimizing

    The consumption of scrubbing material in a scrubber is related to the mass flow of acid gases. Hydrogen chloride (HCl) and sulphur dioxide (SO2) are the major acid gases in an incinerator. By measuring the mass flow of SO2 and HCl in the raw gas going into the scrubber, it is possible to calculate the required quantity of scrubbing material.

  • Gas Detection Solutions for Fertilizer Manufacturing

    Ammonia is a notoriously difficult compound to measure accurately and reliably using standard chemical sampling techniques. The great advantage of the optical laser gas detection technique for quantitative ammonia monitoring is that the optical measurement does not affect the air being sampled – and so a true, undisturbed value for ammonia concentration can be determined. The very high resolution and specificity of the laser method also means that is no interference from other gases in the air (for example,...

  • HCl Monitoring in Air

    Hydrogen chloride (HCl) is a colorless, sometimes slightly yellow, gas. It is an undesired environmental component that may be damaging to workers and the surroundings. Exposure limits have thus been established by industries to make sure that the workers operate in a safe environment. HCl monitoring is especially required for incinerators, coal-fired power plants, aluminum recycling and cement plants. Unisearch offers a reliable and easy-to-use HCl analyzer – the TDLAS-based LasIR system. Studies have...

  • Hydrogen Fluoride (HF) Monitoring in Air

    Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.

  • Measurement solution for high NH3 monitoring from wastewater

    Protea was asked to supply a high level ammonia (NH3) measurement system for a waste water treatment plant. The reflux drums at the inlet to two ammonia stripping towers needed to be measured continuously. Protea designed a solution based around our Solus TDLAS analyser platform and a high level dilution system. The Solus analyser was configured for NH3 measurements in the range 0-500ppm. A dilution system incorporating special dilution probe and 19` control panel was installed before the analyser. This gave a...

  • Gas Detection Solutions for Hydrogen Fluoride (HF) Safety

    Hydrogen Fluoride (HF) is a very useful chemical used in a variety of industries. However, HF is highly toxic with potential fatal consequences with exposure to humans, so facilities that make or use HF should exercise great care. Nevertheless, there is always the risk of leaks from process elements such as valves, pump seals and storage vessels. Tanker loading, transporting and unloading operations also provide opportunity for HF releases. Industrial processes that make or use HF typically have arrays of point...
