Continuous emission monitoring

Integrated continuous emission monitoring equipment for measuring gas, particulate & dust emissions from industrial processes.

The implementation of an accurate and efficient continuous emission monitoring system (CEMS) is critical to ensuring that emissions from your industrial combustion or incineration processes remain compliant with national ambient air quality standards and Environmental Protection Agency’s (EPA) regulations.

Industries have a responsibility to comply with stringent environmental regulations to monitor and control criteria pollutants, while communities that live near these facilities need assurance that they are operated safely and comply with federal, state and local regulations to protect their health and welfare. Continuous, reliable monitoring of gas, opacity, dust, smoke and particulate stack emissions helps facilitate effective combustion and manufacturing practices. It is also crucial to maintaining ambient air quality standards and protecting the safety, health and wellbeing of workers and neighbouring populations.

Smart solutions for gas, opacity, dust, smoke & particulate monitoring

Our extensive range of continuous emission monitors for gas, opacity, dust, smoke and particulate monitoring has been designed to meet the needs of a variety of continuous emission applications, including boilers, filter bag houses, power plants, incinerators and other industrial and marine processes.

Engineered for precision and performance, our instruments are robust and have an exceptional reputation for reliability – making them the industry standard for large OEM customers around the world.

In addition to the CEMS equipment we manufacture, Acoem Australasia is also the exclusive Australia and New Zealand distributor for a number of complementary CEMS products made by our partner suppliers, including:

Particulate monitoring

The World Health Organisation (WHO) identified PM2.5 from fuel burning and industrial combustion as potentially the most damaging emission, affecting the health of more people worldwide than any other pollutant. Even short-term exposure can damage respiratory and cardiovascular systems.

Our single and double pass continuous particulate emission monitors provide reassurance and accurate measurements of the concentration of particulate matter in exhaust gases that pass through industrial ducts, stacks and flues.

Dust monitoring

While all dust can be harmful, dust emissions from industrial processes can significantly impact people’s health based not only on the duration and level of exposure, but also on the size, type and chemical composition of the particles involved – especially for workers at industrial sites and nearby communities.

Acoem dust monitors use the innovative Dynamic Detection Principle (DDP) to measure dust and particulates within exhaust gases from various manufacturing processes. They calculate the dynamic response, or the ratio of light variation to the average light intensity, which varies with the dust concentration.

Opacity monitoring

Excess stack smoke is a sign of poor combustion and high concentrations of dust and particulate – making opacity monitoring an essential part of regulatory compliance.

Acoem opacity monitors use the light transmission technique. Any dust, smoke or particulate present will attenuate the transmitted light and be measured based on the decrease in light intensity due to absorption and scattering. We offer both single and double pass opacity monitoring solutions.

Gas monitoring

Stack monitoring involves measuring gas concentration at the point of emission (stack).

These measurements can be coupled with ambient and background measurements to allow a better understanding of how emissions affect the local and broader environment. Stack emissions monitoring involves monitoring high concentrations of stack air such as CO, NO_x, SO₂ and others with specially designed gas analysers.

Marine smoke monitoring

Shipping companies and port authorities around the world are legally obligated to enforce and comply with International Maritime Organisation global standards to lower ship emissions.

Our marine optical instrument is based on a transmitter/receiver arrangement whereby increased smoke density in the stack gas attenuates transmitted light and causes the intensity of the received light to fall. This reduction in intensity is measured and presented as a percentage of opacity. The higher the level of smoke present, the more light lost and therefore the greater the opacity.
