Removal Of Carbon Disulfide By Pulse Corona

The removal of CS₂by pulsed corona was experimentallyinvestigated. The influences of operation parameters such as pulsevoltage, pulse frequency, gas initial mass concentration, gas compositionand water vapor on the removal of CS₂were investigated. The removal ofCS₂by pulsed corona combined with in situ absorption was alsoinvestigated.Experimental results showed that CS₂could be removed effectivelyby pulsed corona. The removal of CS₂increased with the increase ofpulse voltage and pulse frequency. It was found that the removal of CS₂was higher in Ar gas than that in N₂gas when the pulse voltage applied tothe reactor was20kV. The main product was confirmed to be sulfur. Itwas found that the removal of CS₂decreased with the increase of the gasinitial concentration. The removal of CS₂increased from44.9%to63.4%with the addition of20%O₂in Ar gas. The removal of CS₂increasedfrom44.9%to56.4%with the addition of50%water vapor in Ar gas.The main gaseous products of CS₂decomposition were CO, CO₂, COSand SO₂. The harmful products such as SO₂could be absorbed by Ca（OH）₂with the combination of pulsed corona and in situ absorption. Theremoval of CS₂also increased. The removal of CS₂was increased by15%with the addition of20%O₂gas in Ar gas, by17%with the addition of50%water vapor in Ar gas, respectively.
