Abstract:
Diesel and Heavy Fuel Oil (HFO) emit Sulphur
and Nitrogen Oxides when combusted in boilers. Industrial
boilers burn large amounts of fuel for steam generation. It has
become essential to control these gas emissions from boilers due
to sensitivity to the environment. Packed column is a technology
used for Gas absorption process and distillation process in
industrial applications. This research mainly targets on
utilizing packed column gas absorption for purification of
Exhaust gas in HFO Boiler exhaust. Industrially available
economical packing materials cannot withstand high
temperature flue gas exiting a boiler. The discussed solution
used a combination of a packed column and a wet scrubber to
achieve the optimum performance and cost of packed column
absorber. Cooling effect created by the scrubber made it
possible to use an economical packing material where the
packed bed operated at 90 °C temperature.
