Perma Pure opens Indian industry’s mind to Nafion technology at NTPC’s GETS

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.

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.

Hanovia – 90 Years and Counting

Age is no barrier to innovation at Hanovia!

For 90 years Hanovia, tucked away in the Berkshire town of Slough in the UK, has been quietly innovating. From its early days making UV lamps for treating skin conditions to today’s high-tech UV water treatment systems, the company has always been at the forefront of UV science and, at 90, age is no barrier to innovation!

Hanovia is now a world leader in UV disinfection for applications as diverse as food and beverage processing, pharmaceutical manufacturing, brewing, electronics, swimming pools, buildings, ballast water and fish farms.

To celebrate its 90th anniversary the company hosted a celebration at its HQ on November 3 which was attended the Mayor of Slough, Shafiq Chaudhry, Rob Anderson, the Leader of Slough Borough Council, representatives from SEGRO (which runs Slough Trading Estate), journalists and ex-Hanovia employees.

After a brief talk by John Ryan, Hanovia’s Managing Director, about Hanovia’s long history – and looking ahead to the next 10 years – visitors had a short factor tour which was followed by a cake-cutting ceremony and lunch.

It was fantastic to see so many ex-employees on the day – and we were honoured that the Mayor was able to attend. Everyone found John’s talk interesting and the factory tour was the first time some of the visitors had even see a UV system, so there were plenty of interesting questions!

Before Hanovia – the Slough Connection
Sir William Herschel first discovered ‘invisible radiation’ (infrared rays) in Slough in 1880. His discovery led to Johann Wilhelm Ritter’s discovery of ultraviolet radiation in Germany a year later.

Hanovia and UV
Hanovia’s history goes back to the early 1920’s, when the company started manufacturing UV lamps in Slough for medical treatment. ‘Actinotherapy’ or ‘artificial sunlight’ gained popularity after it was found that it cured rickets and helped in the healing of wounds. From then on, no hospital could afford to be without UV equipment. Hanovia was also one of the innovators of air disinfection using UV.

Ocean Optics introduces surface-enhanced Raman spectroscopy substrates

Gold nanoparticle SERS substrates amplify Raman effects

Ocean Optics has introduced a new substrate for Raman spectroscopy applications. Surface-enhanced Raman spectroscopy (SERS) substrates are highly sensitive, stable and reliable, delivering precise trace-level Raman spectroscopy measurement in applications ranging from chemical and explosive agent detection, to authentication, contaminant screening and quality control in production environments and the laboratory.

Surface Enhanced Raman Spectroscopy

Using precisely controlled gold nanoparticles, Ocean Optics SERS substrates amplify very weak Raman signals by many orders of magnitude. The result is fast, repeatable SERS measurements for the identification and quantification of SERS-active analytes. Detection at the parts per billion and even parts per trillion, level are possible.

Ocean Optics’ unique SERS substrate manufacturing method results in affordable mass production with high repeatability and customization options. Standard substrates are microscope slide format with a 5 mm diameter active area. Ocean Optics uses optical-grade borosilicate glass and high-performance silicone-based adhesive for compatibility with a wide range of solvents. Customized designs are available on demand with a choice of form factor such as swabs and coatings, as well as the ability to impart specificity to particular analytes.

SERS substrates work reliably with the complete range of Ocean Optics Raman instruments, including the IDRaman mini handheld Raman spectrometer.
