Determination of Sulfur Dioxide Concentration in Ambient Air by
using sulfur dioxide analyzer
INTRODUCTION:Sulphur dioxide is a gas. It is invisible and has a
nasty, sharp smell. It reacts easily with other substances to form
harmful compounds, such as sulphuric acid,
sulphurous acid and sulphate particles. Sources of SO2emissions
include industrial processes such as extracting metal from ore, and
the burning of high
sulfur containing fuels by locomotives, large ships, and
non-road equipment from fossil fuel combustion at power plants
(73%) and other industrial facilities
(20%) coal and oil (for example, coal being burnt in a home
fireplace for heating and diesel-powered vehicles). Sulfur dioxide
is also produced from some
industrial processes, such as fertiliser manufacturing,
aluminium smelting and steel making. Natural sources of sulfur
dioxide include geothermal activity
OBJECTIVE: To determine the concentration of sulfur dioxideby
using the Sulfur Dioxide Analyzer (43C-TLE)
MAIN COMPONENT OF ANALYZER
the sample is drawn into the analyzer through the sample
bulkhead.
The sample flows through a hydrocarbon kicker (scrubber) which
allows only
hydrocarbon molecules to pass through the tube wall.
The sample flows into the fluorescence chamber, where pulsating
UV light
excites the SO2molecules.
The band pass filter allows only the wavelengths emitted by the
excited SO2
molecules to reach the PMT. The PMT detects the UV light
emission from the
decaying SO2molecules
The sample then flows through a flow sensor
The sample then flows through a flow sensor, a capillary, and
the shell side of the
hydrocarbon kicker. The Sulfur Dioxide Analyzer outputs the
SO2concentration to
the front panel display and the analog or digital outputs.
Pneumatic System: consists of sample inlet
line, particulate filter, hydrocarbon
scrubber/kicker, dryer , sample cell, reaction
chamber, flow meter, and pump
Analytical System: consists of the UV source
with the associated source filters, lenses, and
optics, as well as the light baffles, the
detector (photomultiplier tube) and bandpass
Electronic Hardware: consists of the
electronic components that control the
analyzer and process the signals.
