Dioxin Monitoring System (GT90 Dioxin+)

The Perfect Solution for Dioxin Monitoring

The GT90 Dioxin+ is designed specifically for long-term monitoring of dioxin emissions. The automatic system represents the cutting-edge technology for dioxin sampling and fulfills all requirements of the dioxin measurement standard. Because dioxins can be harmful to health, authorities have imposed emission limit values that need to be monitored. Monitoring is done in conformity to the European standard EN1948-1. GT90 Dioxin + is MCERTS certified, and the conditions stated on MCERTS certificate complies with QAL1: EN15267-1, EN15267-2:2009

The system is the perfect solution for the continuous isokinetic sampling of hazardous organic compounds in industrial and domestic waste incineration plants. In addition to dioxins, the system is capable of measuring furans and other persistent organic pollutants (POPs), such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). To get even more out of the system, the GT90 Dioxin+ can also be equipped with ParTrace option, enabling heavy metal and fine dust collection.

Unparalleled Dioxin Measurement Limits

The GT90 Dioxin+ was designed to sample even the lowest dioxin and dioxin-like compound concentrations in harsh industrial environments, even in subfreezing conditions. The system has been performance tested and validated, allowing measurements down to 0.0003 – 0.252 ng I-TEQ /m3. The system can withstand dust loads up to 150 mg/m3 and velocities up to 30 m/s without any effect on the performance.

Key benefits

  • Long-term isokinetic sampling
  • Conformity to EN1948-1
  • A sampling of dioxins, furans and other persistent organic pollutants (POPs)
  • POPs such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs)
  • High sensitivity
  • Availability of 100%

Cutting-edge Design

The GT90 Dioxin+ consists of a heated sampling probe unit with zero pressure probe tubes, heated line and control cabinet. The system has titanium probe tubes and cartridges as a standard. For very harsh measuring point conditions optionally we can provide heated exchanger and sampling probe unit valves also made from titanium for very harsh measuring point conditions: In this case, all materials in contact with the sample gas from the tip of the probe tube to the cartridge would be titanium.

The sampling probe unit includes automatic blowback and probe cleaning features. The system can also be equipped with remote access and control, allowing e.g. remote calibrations, leak tests and data download during operation. The used dilution method technique allows working without any flue gas condensate as only a dry cartridge will be transported to the laboratory for analysis.

Dioxin sampling requirements in Waste Incineration

BAT (Best Available Technology) Conclusions for Waste Incineration set new BAT-associated emission levels (BAT-AELs) for the dioxin-like PCBs. The main aim of the WI BAT conclusions is to reduce both air and water emissions from different waste installations. The revised BREF defines the technical basis and BAT-associated emission levels (BAT-AELs) for national authorities in the EU to set operating permits for installations. The BAT-AELs work as a framework for authorities to set plant-specific ELVs, i.e. Emissions Limit Values.
