Industrial processes demand continuous, reliable monitoring to maintain emission control, support regulatory compliance, and drive environmental performance. The OPSIS System 400CS (Cross Stack) delivers accurate, real-time measurement of industrial emissions directly across the stack using advanced optical monitoring technology. With in-situ, non-contact measurement, the system eliminates the need for conventional sampling while providing continuous emission data for enhanced process visibility and informed decision-making.
At NEVCO Engineers, we are committed to providing advanced environmental monitoring solutions that combine accurate measurement, dependable performance, and smarter environmental management. Let’s explore how the OPSIS System 400CS is transforming industrial emission monitoring.
Multi-Gas Monitoring for a Comprehensive Emission Profile
The OPSIS System 400CS enables monitoring of multiple gases, providing industries with a comprehensive view of their emission profile. In its basic configuration using UV-DOAS technology, the system can monitor gases including NO, NO₂, SO₂, NH₃, and Hg. When supplemented with an AR650 analyzer using FTIR-DOAS technology, the system expands its capabilities to measure CO, CO₂, HCl, and HF.
This flexibility allows industrial facilities to monitor the specific pollutants relevant to their operations, from combustion-related emissions to process-specific gases, ensuring complete visibility into their environmental performance.
In-Situ Measurement: Simplicity and Reliability
The System 400CS performs measurements directly across the flue gas path—a method also known as “in-situ” measurement. This approach significantly reduces the complexity associated with sample extraction systems, eliminating the need for:
- Sample transport lines
- Gas conditioning equipment
- Complex sample handling systems
By measuring emissions directly in the stack, the system provides a more representative measurement while simplifying the overall monitoring process.
Optical DOAS Technology: Proven and Certified
The OPSIS System 400CS uses Differential Optical Absorption Spectroscopy (DOAS) technology, employing light absorption to identify and quantify gas concentrations across the stack. This technology has been rigorously tested and approved by several international test institutes and national authorities, including:
- TÜV (German technical inspection association)
- MCERTS (UK environmental certification standard)
This certification provides industries with confidence that the system meets stringent regulatory requirements for emission monitoring.
Fast and Reliable Continuous Monitoring
Continuous measurement provides timely emission data that enables operators to respond quickly to process changes and make informed decisions. The real-time nature of the system supports:
- Immediate detection of emission excursions
- Rapid process optimization
- Proactive maintenance planning
This responsiveness is critical for industries operating under tight emission limits and seeking to minimize their environmental footprint.
Low Maintenance Non-Contact Technology
With no direct contact between the measurement system and the process gas, the OPSIS System 400CS supports efficient operation with reduced maintenance requirements. The non-contact nature of the technology offers several advantages:
- Reduced wear from corrosive gases
- Minimal fouling from particulate matter
- Lower maintenance costs compared to extractive systems
- Extended operational life of measurement equipment
The optical path length is typically 1-2 metres, though both shorter and longer sections can often be accommodated.
Supporting Regulatory Compliance Across Industries
Reliable continuous data helps industries monitor their emissions and support environmental compliance requirements. The OPSIS System 400CS is widely applicable across industries where accurate emission measurement is essential, including:
- Power Generation: Monitoring NOₓ, SO₂, CO, CO₂, NH₃, HCl, HF, and mercury emissions from combustion processes
- Copper Industry: Tracking SO₂, NOₓ, CO, and particulate emissions from smelting and refining operations
- Oil and Gas: Monitoring emissions from refineries, flare systems, and processing facilities
- Sugar and Distilleries: Ensuring compliance with emission standards for boiler operations and process emissions
A Scalable Solution for Future Needs
One of the key advantages of the OPSIS System 400CS is its scalability. The system can be extended with additional gases, more measuring paths, sensors, and other accessories—both at the time of ordering and afterwards. This future-proof design ensures that the system can adapt to evolving regulatory requirements and changing operational needs.
