Air Monitoring 39


OFCEAS is very attractive for industrial installations with explosive area requirements, like petro chemical plants.


Furthermore, the measurement of low concentrations of H2 S in


the fl ue gas by OFCEAS from 50ppb to 100ppm, is also useful when refi neries are required to control their sulfur emissions.


In conclusion, the combination of OFCEAS and LPS allows a new approach of continuous emissions monitoring. And it could be a perfect answer to the lowering of the emission limits by the authorities in the near future (BREF). Gas compounds such as HF, HCl, NH3


, CO, H2 S, and formaldehyde, could be easily measured


in ppb concentrations. The applications where those level of performances are required are numerous, and could relieve many industrials from measurement constrains encountered by older installed instrumentation technologies.


Instruments based on OFCEAS and LPS technologies, LaserCEM®


are already certifi ed by TUV and MCERTS regarding EN 15267. And the manufacturer AP2E, part of DURAG group, is able to supply LaserCEM®


, as well as complete CEMS instrumentation


(including DAHS, dust, fl ow, Hg) via DURAG partners and durag subsidiaries, worldwide.

New heated VOC analyser is truly unique


Signal Group has announced the launch of a new, highly innovative, portable gas analyser, the SOLAR XPLORE. One of the company’s core technologies is Flame Ionisation Detection (FID) for the measurement of volatile organic compounds (VOCs), and the new instrument brings the unique advantages of the latest fi xed analysers to a compact, portable device that is set to dominate the market.


“There are two unique features in the SOLAR XPLORE that set it apart from any other analyser in the world,” explains Signal’s Stephane Canadas. “Firstly, we have taken the detachable tablet interface from our S4 fi xed analysers and built it into the new instrument. This will be an enormous benefi t for stack testers that have to travel up ladders and across roofs, because using the tablet, they will be able to operate the analyser wirelessly from a convenient location up to 50 metres away.


“Secondly, the new analyser can be fi tted with twin FIDs, which means that users will be able to monitor total VOCs, methane, and non-methane VOCs (NMVOCs) simultaneously.”


The new SOLAR XPLORE is also supplied with an ethernet connection and software to enable remote operation. This means that users will be able to manage the analyser and monitor the data from almost anywhere in the world.


New design features include an inbuilt datalogger and a lightweight but robust frame. However, users will be particularly impressed with the chassis design, because it allows the internal electronics to simply slide out on a rail and unfold for maintenance operations.


Summarising, Stephane says: “Anyone with responsibility for monitoring VOC emissions, especially if they need to discriminate NMVOCs, will be tremendously excited by this development. As a portable heated FID, the SOLAR XPLORE offers everything that our customers wish for, and more, so we share their excitement!”

World class oxygen analysis technology enables optimal combustion effi ciency and compliance with international, environmental legislation


Fuji Electric offer an oxygen analyser modular platform, built around zirconia sensor technology, which provides the perfect solution for combustion control in boilers, incinerators and furnaces. This cutting-edge device facilitates the reduction of CO2


, CO, SOx, and NOx emissions and saves energy – and extends the combustions plant’s longevity.


Fuji’s analyser is widely used to continuously measure oxygen concentration in combustion exhaust gas emitted from industrial boilers and furnaces. It is ideal for combustion management and control, in applications such as waste incinerators as well as all sizes of boilers, to control combustion and therefore enable a considerable reduction in energy costs.


This instrument’s measurement principal is based around zirconium oxide, that conducts oxygen ions when heated. The analyser measures oxygen concentration by sensing the electromotive force generated by the difference of oxygen concentration in air and the sample gas.


Fuji have years of experience in providing state-of-the-art instrumentation suited for some of the harshest environmental and industrial conditions. Their technology is ubiquitous in some of the most demanding industries such as steel, petroleum and petrochemical, energy, ceramics, food and beverage, paper and pulp and textiles.


This versatile and highly user-friendly analyser platform transmits measurement data securely and reliably via the new Hart Protocol with RS-485 standard electrical signalling. It has been designed to facilitate the reduction of excess air in the combustion process, which leads to a signifi cant reduction in costs by enhancing combustion effi ciency. The zirconia sensor, which has a signifi cantly longer life expectancy than others of its kind, is quick and easy to replace, which means far less maintenance and its associated delays. No air supply or fl ue gas extraction is required – and the instrument typically generates measurement data within 4-7 seconds, as well as performing predictive and advanced diagnostics.


This device also includes several important safety features. The converter shuts down the power supply to the detector if a thermocouple burnout is detected, it can also be quickly and easily cut off in emergencies and a key lock facility signifi cantly reduces the probability of operator error.


See more details on Fuji Electric website and watch how the ZKM/ZFK8 oxygen zirconia analyser platform helps the users optimise their process and save costs.

Usually, high nitrous oxide emissions occur from agricultural soils, where the availability of mineral nitrogen is high because of nitrogen fertilisation and other management practices. Since the nitrogen cycling in cold Arctic soils is slow, they have previously been regarded as unimportant nitrous oxide sources. Based on accumulating evidence during the past years, however, this is not always true: nitrous oxide release has been found to be a common phenomenon in permafrost-affected soils, and the emissions increase with warming, disturbed vegetation cover and permafrost thaw.

“The nitrogen release from thawing permafrost can substantially improve the availability of nitrogen in Arctic ecosystems, which, in addition to the direct climatic feedback in the form of nitrous oxide, may have important consequences on carbon fi xation by plants and eutrophication of water systems,” says Postdoctoral Researcher Maija Marushchak from the University of Eastern Finland, the lead author of the study.
