Sustainability
Most cross-duct systems measure 1-2 gases over a range of
wavelengths. Furthermore, as there is no contact with the target
gases, they can require less maintenance and operator involvement.
One drawback is that cross-duct systems can be more
complicated to calibrate, although this can sometimes be overcome
using an automatic calibration system.
The author's company's in-situ cross-duct analyzerc
for measuring
gas component concentrations applies a highly selective,
optical measuring principle of tuneable diode laser (TDL) absorption
spectroscopy. The laser is selected for a single wavelength
in the sample gas absorption spectrum, where no cross
sensitivity from other gases occurs. The absorption line is
scanned, and the receiver detects the absorption caused by the
measuring component and calculates the gas concentration.
While in-situ analyzers can be installed directly on the stack
with no sample handling, around 80%-90% of plants worldwide
have a strong preference for extractive methods that tend
to offer a lower cost of ownership.
In comparison to in-situ measurement, extracting a sample
means only that the probe is in contact with the gas and not
with any delicate optical components. After conditioning, a
clean and dry sample is presented to the analyzer. The system
can then be installed in an air-conditioned cabinet or shelter,
protecting it against potentially harsh ambient conditions.
Whereas in-situ devices are usually limited to 1-2 components,
multiple components can be measured simultaneously
by using a sequence of sensors in an extractive system, requiring
fewer holes in the stack.
With the analyzer system usually installed at ground level
in a clean and accessible environment, maintenance is much
more convenient, components are easy to work on and test gas
cylinders are available nearby to easily calibrate the devices.
A measured future. While addressing climate change is going
to take a combined effort by governments, organizations and
individuals worldwide, measurement systems are going to play
a crucial role in helping the world to reduce emissions. As the
value of these systems becomes more widely understood and the
technologies become easier to implement, CEMSs will certainly
be set to play an increasingly central role in ensuring that all industries
play their part in finding ways to limit their emissions.

3 Ways to Drive Progress with Sustainability and
Net-Zero Targets
As sustainability remains an industry imperative, it's essential you make progress with both
your near- and long-term sustainability targets. Whether identifying improvements in current
operations, cost-eff ectively integrating new technologies to existing processes or innovating
processes to include new feedstocks and products, your approach to sustainability demands
extensive understanding, planning and knowledge.
