Removal of ethylene by steamer corona discharge

Abstract

In order to store fresh fruits or vegetables, exhaled ethylene gas should be removed. Pulsed streamer corona discharge has been applied for this purpose. Ethylene of 20 ppm concentration diluted in the air can be effectively removed with more than 99.5% efficiency with a treatment period of 0.3 s. It was experimentally confirmed that the energy efficiency of the ethylene removal with pulsed streamer corona discharge generated by the fast-rising square wave voltage was four times higher than that with the DC corona discharge, and eight times higher than that with the AC corona discharge.<>
