Bio-organic waste has great potential for... green energy extraction. Landfill waste is also a cog in the waste-to-energy chain; Methane is extracted from this, which can be used to generate energy. Methane gas is generated by the anaerobic decomposition of (sanitary) landfill waste. Typical gas concentrations are 55% CH4 (methane) and 45% CO2 (carbon dioxide). The methane gas is recovered by vacuum sources sunk in the landfill.
Problem
As the operators pump gases through the vacuum, an influx of oxygen will occur. However, oxygen is toxic to the microbes that metabolize the waste and thus generate the methane. First of all, influx of oxygen can slow down the process; oxygen kills the microbes, slowing the rate of decomposition and gas production. However, there is a second important reason to control oxygen. The presence of oxygen in flammable gas creates a potentially dangerous situation.
Solution
The InstaTrans transmitter or 3010TAC/PAC oxygen analyzer with a lower limit of 0-10 ppm are designed to accurately monitor even the lowest oxygen levels. The analyzers can be installed in different locations; they are suitable for safe zones as well as for explosive environments (ATEX).
