Emissions and Process Gas

CEMS and Process Instrumentation


Governmental Authorities such as States Environmental Protection Agency’s and Australian Clean Air Regulations set stack emissions limits for pollutant concentrations at the point of release, and facility operating licences require emissions monitoring on a continuous basis. Continuous Emission Monitoring Systems (CEMS) are operated 24/7 in harsh environments for regulatory purposes. AquaGas CEMS product range features robust and versatile sampling systems, analysers using dedicated technologies, and certified data acquisition and reporting systems necessary to comply with emissions standards. AquaGas Pty Ltd’s integrated systems and solutions are designed to achieve high reliability, long-term performance, and simplicity of use through operations and maintenance. The availability rate and accuracy of the consequent emissions data are two factors crucial to local authorities and plant operators.

Emission and performance testing must be periodically performed on site by stack testers and mobile laboratories. AquaGas Portable Emission Measurement System product line offers our clients innovative, robust, and accurate solutions to efficiently handle short term compliance measurement on industrial sites.

Control and automation of industrial processes such as combustion, flue gas filtration (cyclone, electrostatic precipitator, deNOx, Scrubbers…) or pyrolysis requires online instrumentation with fast response time and the ability to withstand their harsh installation environment. AquaGas products and systems are conceived to operate 24/7 in the heart of industrial settings bringing key functions, and high precision technologies to automate your industrial processes.


AquaGas products and systems are used worldwide and suitable for an extended field of applications including:

Large combustion plants: coal or natural gas fired power stations, cement kilns, furnace flue gas, boilers…

Oil & Gas: coal or biomass gasification or pyrolisis, syngas, chemical and refining facilities…

Manufacturing industries: Mining, paper mills, glass works, offgas from the Steel and Iron industries, blast furnaces, converters, direct iron smelting reduction, endo and exo gas generators for heat treating, pharmaceutical plant, gas production…

Waste management: domestic and industrial waste incinerator, solvent incinerators, water treatment plants, laboratories, anaerobic digestion or fermentation processes, landfills…

  • Isokinetic Stack Sampling

    POPs – Persistent Organic Pollutants
    POPs have been determined to be the most significant part of emissions to the environment which cause adverse health effects. These include, dioxins (PCCD/F), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), Hexachlorobenzene (HCB) and others. These compounds have a high stability, low volatility, and are degraded very slowly. Due to their lipophilic character, an accumulation in the human body takes place.

  • Insitu Monitor

    Fine dust
    TSP, PM10, PM2.5, PM1  are the portions of solids in gases being the focus of concern for pulmonary health effects.

    Combustion Gases
    O2 and combustibles online monitoring for the control of combustion processes in large scale industrial facilities.
