Stack gas sampling system

SEC™ BOX

The dry extractive SEC™ system dries the gas sample at the sampling point, eliminating the necessity of an expensive heated sampling line.

It uses an exclusive high performance permeation technique, designed to meet almost all gas sample conditions. Ideal for highly soluble and corrosive gases.
Optional built-in temperature & velocity sensors or STACKFLOW 200 flow meter on the same flange

To be used with unheated analyzers such as MIR 9000, MIR 9000CLD, MIR 9000ASD.

The SEC sampling system uses the Cold Dry Extractive method (Dry Basis Analysis).

  • Sampling probe equipped with double stage particulate filtration
  • Direct span gas injection for a complete system calibration
  • Permeation-based drying system avoids loss of highly condensible gases (e.g. HCl, SO2,NO2 and HF)
  • Automatic & periodic back-purge functionality for longer maintenance intervals
  • Clean & dry sample transferred via unheated line (up to 100m distance) at ambient air temperature
  • Large selection of probes available (depending on process conditions: stack diameter, gas temperature, water content, particulate concentration)
  • Heated probe with choice of materials & lengths
  • Sludge Incineration
  • Gas turbines
  • Power Plants
  • Boilers
  • Paper Mills
  • Cement
  • Boilers
  • Paper Mills
  • Glass, Petrochemical & Chemical Industry
  • Waste Incineration( Municipal Energy from Waste or Industrial)

Cold Dry Extractive (Dry Basis Analysis)
The gas sample is extracted and conditioned before transport, in order to have all moisture and condensible components removed prior to its analysis. Upon arrival
to the analyzer, the sample is clean, dry, at ambient temperature & water interference-free.

COMPLIANCE WITH: EU Regulation IED (WID / LCPD / MCPD directives) and US EPA (40 CFR 60 & 75)
