What Pollutants Can EcoChem Analytics CEMS Monitor?

Updated

EcoChem Analytics builds continuous emissions monitoring systems (CEMS) and analytical instruments for criteria pollutants, mercury, PAH (polycyclic aromatic hydrocarbons), and particles. The core of a typical EcoChem CEMS is the MC3 multicomponent IR gas analyzer, which the company says can measure up to 8 gas components plus O2 in a single unit — including NH3, HCl, HF, NOx, N2O, SO2, CO, CH4, H2O, and CO2. This makes the system relevant to facilities that need continuous flue gas monitoring across a broad set of pollutants rather than a single gas.

Pollutants and measurement targets

EcoChem's product line covers several categories of emissions and air-quality measurements:

Category Measurement target Product / component
Criteria and process gases NH3, HCl, HF, NOx, N2O, SO2, CO, CH4, H2O, CO2, O2 MC3 multicomponent IR gas analyzer (up to 8 components plus O2)
Carbon aerosol / particulate matter Carbon aerosol, particulate matter PAS 2000 Photoelectric Aerosol Sensor; carbon/oxygen sensors
Mercury Mercury (listed in the company's stated monitoring scope) CEMS configuration
PAH Polycyclic aromatic hydrocarbons (listed in the company's stated monitoring scope) CEMS configuration
Stack sampling Flue gas stream at the stack HW5 Heated Probe

The MC3 is described as specifically designed for continuous monitoring of a flue gas stream. The PAS 2000 is a real-time ambient air monitor for carbon aerosol, and EcoChem also lists compact real-time monitors for particulate matter.

What a complete EcoChem CEMS includes

EcoChem emphasizes single-source supply — "Total Responsibility ... From Probe to Printout" — because it manufactures its own analyzer, probe, and data acquisition system. A typical MC3-based CEMS is delivered as a standalone cabinet or panel and combines:

  • MC3 analyzer — the multicomponent measurement core
  • PLC and sample system components — for handling and conditioning the gas sample
  • HW5 Heated Probe — stack interface; its design allows the entire probe to be removed without pulling the flange
  • Cemtrac3 Data Acquisition System — software for emission compliance and regulatory reporting
  • Hovacal — a portable calibration gas generator for gas-vapor mixtures with selectable humidity

Where these systems are used

EcoChem lists the following industries among its applications:

  • Energy-from-waste facilities
  • Fertilizer production
  • Chemical and petrochemical plants
  • Coal- and gas-fired power plants
  • Cement kilns
  • Industrial boilers

These are settings where multiple regulated pollutants must be tracked continuously and reported for compliance.

Choosing the right configuration

The right setup depends on which pollutants you are required to monitor and whether you need stack measurement, ambient monitoring, or both. If your permit covers a broad set of gases, the MC3's ability to measure up to 8 components plus O2 in one analyzer reduces the number of separate instruments. If carbon aerosol or particulate matter is the target, the PAS 2000 or the particulate monitors are the relevant products. For mercury and PAH, confirm the specific configuration with EcoChem, since the website states these as monitoring capabilities without listing a dedicated standalone analyzer for each.
