Abstract
Field experiments are being undertaken to trial the effectiveness of the electro-fenton and electrocoagulation processes to remove H2S from condensed steam at Wairakei. The cooled condensate and accompanying gas (~0.4wt% gas in total of which 97wt% is CO2 and 1.5wt% H2S) is passed through the electrochemical cell at 450 ml/min. Preliminary experimental results show that H2S is easily removed at >97% efficiency from the gas stream. The aim is to collect sufficient data across a range of experimental conditions to determine the factors which affect removal efficiency of H2S which would help design a larger scale reactor.
