Improved CEMS Accuracy and Reliability With Sample Conditioning Systems Using Nafion Technology

Perma Pure, global leader in the sample gas conditioning space, presented a paper about the use of Nafion technology in continuous emission monitoring systems at the 'Global Energy Technology Summit' (GETS) 2014, organized by NTPC, India.

With the recent notification issued by the Central Pollution Control Board for continuous emission monitoring systems (CEMS) in highly polluting industries, the Indian market is flooded with CEMS enquiries but the major focus is on analyser specification. Mr. Gene Bohensky, Global OEM Sales Manager, Perma Pure, USA, highlighted the importance of sample conditioning systems in CEMS. The gas analyser reads what it gets as a sample so it is very important to choose the correct sample conditioning system.

Mr. Bohensky showed lab results of the difference in SO₂ readings of different flue gas compositions, with the most common 'Sample cooler-based gas conditioning system' and 'Nafion-based sample conditioning system'. With the use of flue gas desulfurization (FGD) and Selective Catalytic Reduction (SCR) to reduce SOx and NOx in stacks, pollutant gases emissions are reduced by more than 90% and the measurement required is within 100ppm . At such low levels, the Nafion-based system provides very accurate readings when compared with cooler-based systems. At higher measurement levels, Nafion systems reduce acid mist formation, which gives longer life to the gas analyser and more trouble-free operation overall.   

In his paper presentation, Mr. Bohensky also showcased case studies of "Chevron - El Sugondo - Monitoring SOx" and "Toyota Motor Manufacturing - Measuring NOx" . The technology got the attention of senior technocrats and they discussed measures to adapt the technology to Indian market requirements.

Abstract of Paper Presentation

The global regulatory focus on the reduction of SO₂ emissions has led to the adoption of a range of flue gas desulfurization (FGD) techniques, among others, to control them. Protecting the environment from the harmful emissions of power plants requires CEMS to be accurate and reliable in long-term operation. The most common sample conditioning systems use thermoelectric (Peltier) coolers to chill the sample and remove the moisture in the liquid phase. However, it has been shown that accuracy suffers when monitoring SO₂ or NO₂ as a portion of the sample is lost while the water is condensed. Secondly, such systems have reliability problems as the wet and dirty samples foul sampling lines and cooler elements, making it difficult to achieve good measurements. In this paper, real-world experience with sample conditioning systems using Nafion membrane technology is presented that demonstrates their ability to preserve the composition of the gas in hot, wet, and dirty samples and guarantee accurate results over a long service life. This experience provides power plants and refineries with the confidence to deploy an effective alternative that both improves measurement accuracy and analyser reliability.

Conclusion

Nafion-based sample conditioning systems installed in the field have demonstrated their theoretical advantages by providing more accurate results, being more reliable and proving less expensive to install and maintain. Such systems are well suited for FGD because of the extremely low range of SO₂ measurements that can be made to maintain the accuracy as well as the efficiency of the CEMS. Today, as permitted levels of SOx and NOx are continually being reduced, it is even more important to consider specifying a Nafion-based system for your CEMS or process analyser. With decades of real world experience, Nafion dryers provide end users with a cost-effective and reliable alternative to thermoelectric cooler-based systems - one that provides more accurate measurements and helps protect the environment.
