OMA Flue Gas Continuous Online Monitoring Analyzer

Scalable All-Solid-State Emission Monitoring Technology

The powerful OMA-CEM integrates a UV-Vis diode array, a non-dispersive infrared detector, and a tunable-wavelength diode laser: the UV-Vis diode array is used to measure SO. ₂ , NO, NO ₂ ; Non-dispersive infrared detection is used to measure CO and CO. ₂ ; Tunable-wavelength diode lasers are used to measure O. ₂ A central graphical user interface manages the entire system—from system zeroing to displaying the real-time concentrations of the monitored components. The OMA-CEM boasts a full dynamic range, enabling seamless monitoring of analytes across concentrations from low ppm levels to high percentages.

AAI is committed to performing concentration measurements that exceed regulatory requirements. Our solid-state systems now offer detection limits that will enable your processes to meet future pollution regulations.

Application fields

Continuous online monitoring of flue gas

Modern factories are generally required by local environmental laws to monitor the concentrations of specific chemical substances they emit into the atmosphere. As environmental protection becomes increasingly stringent and widespread, more and more factories around the world will need sophisticated analytical tools to comply with environmental regulations.

The government’s environmental protection authorities have very strict regulations for continuous online monitoring systems for flue gas, stipulating that these systems must monitor the concentrations of gases such as SO2, NOx, CO, CO2, and O2, and are required to report emission concentrations to the environmental protection authorities in real time.

Reducing emissions is a critically important environmental issue. However, asking factories to invest in and maintain a very expensive analytical system would not yield direct financial benefits. Clearly, an ideal continuous online flue gas monitoring system should be both cost-effective and highly performant. The OMA CEMS is a complete, high-quality continuous online flue gas monitoring system that can continuously monitor the concentrations of various dynamic flue gas components.

Technical concept

Monitoring Principle

The OMA online analyzer uses the principles of ultraviolet and visible spectroscopy to determine the concentrations of chemical components in a sample. The OMA system analyzes the absorbance of the sample across wavelengths from 200 to 800 nanometers, and the data is captured by a 1024-element photodiode array detector and transmitted to a processor for data analysis, yielding high-resolution absorption spectra.

Optical structure

The OMA process online analyzer uses a long-life xenon lamp as its light source to transmit signals that come into contact with the sample via a flow cell. This signal is emitted by the light source and transmitted through an optical fiber cable into the flow cell, where it interacts with the sample gas. Samples composed of various chemical substances exhibit unique absorption characteristics for light. The resulting light signal then exits the flow cell, travels back to the detector via another optical fiber cable.

User interface

AAI’s proprietary ECLIPSE software processes the acquired spectral data into actual concentration readings. On the touchscreen controller, the analyzer operator can easily switch between different interfaces—such as trend graphs, spectra plots, concentration readings, and more—and can independently and at any time set and adjust alarms, outputs, purge functions, zeroing, and other parameters.

Safety performance

Most analyzers directly introduce the sample into the analyzer’s housing for measurement. However, if the sample is toxic, highly corrosive, or explosive, this could be extremely dangerous. The OMA design is unique: instead of introducing the sample into our analyzer, we guide the optical signal into the sample itself. The sample flows only through a flow cell and never comes into contact with the analyzer. The flow cell is connected to the analyzer via an optical fiber cable.

Sample system

The OMA is designed specifically for direct monitoring of high-temperature or water-containing samples. This design philosophy allows us to simplify the sampling system while preserving the integrity of the samples. Drawing on our extensive experience in sampling system design, we’ve found that many different applications share striking similarities yet exhibit subtle differences from one another. Therefore, we tailor each sampling system uniquely to the specific requirements of every individual project—starting from analyzing the user’s sample data and gaining a deep understanding of their process, through detailed design drawings, and culminating in actual production and system integration. For each user, we create a sampling system that is 100% perfectly matched to their needs.

Optional models

OMA products of various models share the same electronic architecture, and their monitoring functions and performance are identical. The differences among these models lie in their external structural designs and the materials used, with the aim of meeting the diverse requirements of different applications.
