Multi-sensor system for selective methane measurements in harsh environments

Abstract

We present a multi-sensor system for the detection of methane in crankcases of large dual fuel or gas engines to prevent exceedance of the lower explosion limit (LEL). It contains a total of four sensors each based on a different detection principle. To test the approach two systems were installed at a stationary power plant with a large dual fuel engine for long-term test with an online GC as reference system.
