Ultraviolet H2S and/or Odour Monitoring

These systems have been designed for the continuous monitoring of Hydrogen Sulphide (H2S) and/or other “odours” within the Outlet stack after odour control equipment on Waste Water Treatment Works. Various ranges of detection are available from low ppb to ppm levels (H2S). Also used to sequentially sample other ducts around the odour control plant with the aid of modern dilution systems.

Sysrem Specifications

  • System can be configured to operate from either 110V or 240V mains supply.
  • Standard cabinet is supplied on a plinth with viewing window and must be located within a relatively dust free environment with heating and lighting.
  • High temperature version available to “crack” sulphurs at 625°C. Produces three Analogue 4–20 mA signals a) SO2 only; b) Total Sulphur (SO2 + H2S + Mercaptans + some NH3); c) Total Reduced Sulphur b) minus a).
  • Low temperature version available to crack “H2S” at 300°C. Produces three Analogue 4 – 20 mA signals a) SO2 only; b) Combined Sulphur (SO2 + H2S + some Mercaptans, less than 5%); c) Hydrogen Sulphide b) minus a).
  • Proven sample line length up to 100 metres using specialist tubing.
  • Optional flow failure facility on sample pump (VFC).
  • Optional text messaging of alarm and fault conditions – subject to suitable network coverage.
  • Supplied with plinth for floor mounting in designated safe area.
  • Dilution system option for high level gas streams and/or sequential sampling other gas streams on the odour control plant back to a single analyser.
  • Pumped system to counter the issues related with differential pressure systems caused by changes in flow and pressure.
  • Standard system to be serviced every 6 months. This may reduce based on site conditions or may increase if our dilution system has been included.
  • Standard Instrumentation Cabinet 1600 x 600 x 850 mm.
  • Safety systems installed to meet HSE judgement on ATEX Directive for Zone 1 and Zone 2 gas stream applications.
  • Standard systems can be easily modified for multi gas applications or to meet specific site requirements as necessary.
