Exhaust gas analysis is frequently required
for incinerators and other combustion processes that produce corrosive waste
gases such as SO2 and HCl.
Some gases are inherently corrosive while
others are soluble and can produce acids when dissolved in condensate that is formed
as gases cool. If these gases do not require analysis, the best approach is to
remove them before analysis.
Ideally, the sampling system in these cases
should be designed to continuously extract, filter, and scrub the flue gas before
it goes to the gas analyzer.
Our preferred approach is to filter the gas
at the sample point while it is still hot. This ensures that the particulate is
removed prior to formation of condensate. After that, condensate formation may
occur freely without risk of creating a particulate slurry and plugging the
sample lines.
The 7240 / 7300 Series Systems have been
designed for this purpose. The sample gases are drawn into the high temp probe and
continue on into the heated particulate filter. Next, they travel to the water
wash system where they are cooled and scrubbed of corrosives. They are then sent
to the gas analyzer cabinet for final analysis.
FEATURES
- Economical and reliable sample gas cleaning system
- Allows analysis of acidic flue gases
- Can be used on samples with high particulate
- Only small amount of 'make-up' water required
We have used these systems on medical waste
incinerators, municipal waste gasifiers, and other processes that produce corrosive
or aggressive gases.

analyzer systems, give Mike or Dave at Nova a call, or send us an e-mail.

My home computer was recently infected with
a nasty virus called Live Security Platinum. This particular virus is carried
into and installs on a computer via a Trojan horse virus. It seems to have loaded
onto my computer while I was downloading a graphics pattern for a construction diagram
that I was producing.
This rotten malware takes control of the
computer and poses itself as an anti-virus program. It flashes the usual fake
warnings about dangerous virus and malware infections. To be saved, all you
have to do is purchase a key code. The ‘program’ will then remove all of the ‘infections’.
The particularly annoying thing about this
virus is that it prevents many other programs from starting. It may also block
internet links, claiming that they are not trustworthy. The Remove Program
function in Windows Control Panel also does not seem to work.
Fixing the problem requires consulting the
internet using another computer that is not infected.
Some websites have posted the activation
key for this fake antivirus ‘program’.

I forget which key I used. This key doesn’t
actually remove the virus, but it does cause it to settle down a little and
allow other programs to work.
To remove the virus, I used a free program
called Chameleon by Malwarebytes. It worked quite well. It even resolved some
other issues possibly caused by other viruses on the system.

This virus annoyed me because interfered
with productivity and caused me to miss a minor deadline on a task. Thankfully,
the fix was fairly simple and conclusive. There was a satisfying irony to using
its own activation code to help deactivate and ultimately remove it.
Happy surfing!
