Mobile Laboratory Facility
In
addition to our in-house laboratory facilities, CleanAir has a fleet
of trailers and trucks that can provide a dedicated, fully-equipped
on-site lab for wet chemistry, gas chromatography, FTIR and Continuous
Emission Monitoring (CEM) systems. Regardless
of location, our mobile laboratories can be transported to your
testing site.
A dedicated wet lab speeds sample turnaround time and virtually eliminates problems due to sample degradation or loss.
Delays resulting from sample train contamination or overloading absorbing solutions are minimized due to rapid detection of these problems while the test crew is still deployed at the testing location.
In addition, air toxics can be analyzed using an on-line system such as a gas chromatograph or gas monitoring system.
Other benefits gained from real-time data include:
Recovering valuable materials lost during the process
More accurate emission inventories and factors
Optimizing process emissions to achieve top performance
Pinpointing contaminant sources in a multi-source facility
Improving control of air quality in the workplace
Gas Chromatography
On-line gas chromatography is used to generate real-time compound
speciated data. Our Analytical Services team has a wide variety
of expertise in direct-sampling and quantifying specific compound
emissions using gas chromatography. Various compounds are speciated
and quantified using the following test methods:
Method 15
Utilized to measure the emissions of reduced sulfur compounds
from tail gas control units of sulfur recovery plants, hydrogen
sulfide in fuel gases and where specified in other applicable subparts.
Method 16
This method determines total reduced sulfur compounds from
recovery furnaces, lime
kilns and smelt dissolving tanks at kraft pulp mills and fuel gas
combustion devices at petroleum refineries.
Method 18
Speciated gaseous organics emitted from industrial sources
are determined by this
method.
Fourier Transform Infrared (FTIR) Spectroscopy
Clean Air has the capability to perform Fourier Transform Infrared
(FTIR) Spectroscopy for the analysis of various gaseous emissions
from stationary sources. The test methods using FTIR for analysis
are Method 320 and 321. We have the necessary field experience with
the FTIR as well as the knowledge and skill to create new FTIR standards,
test protocols and methods.
Method 320
This
method determines compound-specific concentrations in a multi-component
vapor
phase sample in a closed-path gas cell. Specifically, organic or
inorganic compounds
which absorb energy in the mid-infrared spectral region (about
400 to 4000 cm-1). A computer program is used to analyze infrared
spectra and report compound concentrations.
Method 321
This method determines hydrogen chloride (HCl) concentrations
in a multi-component
vapor phase sample in a closed-path gas cell. Specifically inorganic
compounds which
absorb energy in the mid-infrared spectral region (about 400 to
4000 cm-1). Computer
software is used to analyze infrared spectra and report HCl concentrations.
