Automated Desulphurisation Control – Saves Money
Microbiological desulphurisation will significantly reduce the H2S levels in the Bio-Gas produced from Anaerobic Digestion which has significant advantages when the gas is being used downstream as a fuel gas for electricity generation. By introducing & controlling a small volume of oxygen into the Bio-gas the H2S level can be reduced by as much as 90%. Needless to say if the oxygen level is too high the whole process can be damaged & the yield of Bio-gas drastically reduced.
The Awi-Flex multi function Bio-gas analyser is designed for continuous analysis of a number of parameters including CH4 / CO2 / H2S / O2 / H2 as well as automated “real time” control of the desulphurisation process. This is achieved by controlling the Oxygen injection from dedicated blowers. It features a built in industrial PC interface which allows easy access to the recorded data, sensor parameters & system diagnostics as well a allowing Fuzzy logic automated control of an air feed compressor & associated shutoff valves.
