Vandenilio sulfido koncentracijos mažinimas biodujose

Abstract

Global atmosphere pollution and its influence on the environment leads investigation of renewable energy technologies. One of the effective biomass conversions to energy technologies is anaerobic digestion. Biogas contains hydrogen sulphide (H2S), which has to be removed. The aim of research is to analyse the H2S reduction in biogas using liquid ferrous chloride (FeCl3). Experiments were performed on the organic wastes composed of 85,1 % pig manure and 14,9 % animal by-products. The organic load was applied in the range of 2,0 – 6,0 kg/(m3·d). Results indicate that H2S concentration in biogas depends on applied FeCl3 concentration. Depending on the organic load, to reach a stable 230 – 250 ppm H2S concentration, has to be used 0,05 – 0,16 ml/l of FeCl3
