Volumetric Estimation of Biogas Content

In this paper, we develop the method of volumetric analysis to estimate biogas content due to using the gas analyzer (Gas Analyser Chemical Laboratorial-1). We propose the list of absorbing chemical solutions and sequence of their application, notably solution of 50 60 % sulfuric acid – for ammonia absorption; saturated solution of I2 in 0,1 М water solution of KI – for hydrogen sulphide absorption; and solution of 35 % potassium hydroxide – for carbon dioxide absorption. Catalytic oxidations of methane and hydrogen should be conducted together at the temperature of 900…950 °С in electric furnace equipped by thermal couple and automatic temperature controller. We measure biogas content obtained in the laboratorial bioreactor by co fermentation of pig manure and apple residue to test the device and to appraise the gas analyse method. We also present the protocol of biogas pattern measurement. The biogas content obtained from the laboratorial bioreactor has such residual moisture and NH3 – 6,6 %; Н2S – 4,2 %; СО2 – 21,4 %; H2 – 1,08 %; CH4 – 65,22 %; N2 – 1,49 %. The simple device construction and reduced analytical equipment costs compared with other physical-chemical and physical methods of gas analysis are the advantages of gas analysis volumetric method.
