Case study H2S sensor optimizes odor emissions control at Vesthimmerland Biogas Vesthimmerland Biogas wanted an alternative to grab sampling for measuring the plant's odor emissions. To achieve this, two SulfiLoggerTM H2S sensors were installed in the CO2 discharge stream. This eliminated the plant's need for manual grab samples and costly tests by external bodies, and the sensors' real-time data furthermore provided valuable insights into biofilter and scrubber performance.

Case study Biogas plant improves carbon filter performance using H2S data Vesthimmerland Biogas sought an automated rather than manual H2S monitoring setup to optimize filter performance and protect plant equipment. This was achieved using two SulfiLogger™ H2S sensors installed before and after carbon filters in the upgraded biomethane stream. This approach enabled real-time tracking of filter performance, while also boosting the operator's confidence to perform other plant optimizations.

Case study Inline H2S sensor optimizes CHP engine efficiency at Haerup Biogas Danish Biogas plant Haerup Biogas wanted to enhance the efficiency of its CHP engines and reduce maintenance on H2S sensor equipment. To achieve this, the operator installed a SulfiLoggerTM H2S sensor, offering continuous in-pipe measurements for early biofilter cleaning alerts. This proactive approach reduced sensor maintenance needs, minimized the risk of gas flaring, and optimized the plant's overall efficiency.
