Safety of biogas production
Published: 24 February, 2014
A major Scandinavian producer of Biogas has selected MICHELL INSTRUMENTSí XTP601 oxygen analysers to monitor O2 levels for safety and quality at two sites in Sweden.
The XTP601 oxygen analyser is used to continuously provide readings of the levels of O2 in the process. In general, the lower level of oxygen in these applications should be no more than 0.5%, with a danger level of 4%. The XTP601 has alarms to shut down the plant if oxygen levels approach the danger level to ensure safety.
One plant produces biogas from sewage while the other uses food and garden waste, however the biogas from both plants is used as a transport fuel. Despite the different feedstocks, the process of upgrading the gas for use is the same. The biogas must be upgraded to 95% methane.
