In this series of experiments a two-stage process utilising a plasma reactor and chemical scrubber were investigated for their ability to control the NOx emissions in the exhaust gas of a diesel engine.The first stage a non-thermal plasma reactor was used to oxidize NO to NO_2. The second stage utilised an aqueous solution of Na_2SO_3 was used to convert the N0_2 into Na_2SO_4.The results of these experiments showed that a reactor using a pulse discharge power supply performed better than an AC power source. The pulse discharge power source was found to be less influenced by gas flow rate, produced less pressure drop and fewer unwanted by-products such as CO and N_2O.Final results showed that the two-stage process was able to remove nearly 85% of NOx from a 300ppm NO concentration.
