Online VOC Monitoring for Renewable Natural Gas Plants

Enabling more efficient biogas and landfill gas upgrading, increased biomethane plant uptime and reduced operational costs


Growing demand for renewable energy sources and incentives to generate biogas from waste has put suppliers and operators of RNG plants under pressure to accept a diverse range of feedstocks. This leads to unpredictable levels of volatile organic compounds (VOCs) in the gas that can significantly impact plant efficiency and uptime. When biomethane is being injected to the gas grid, the commercial penalties can be severe if purity levels are not consistently met.

The BioSpec VOC analyzer accurately monitors individual ketones and terpenes as well as hydrogen sulphide, ammonia and other components. This gives operators an accurate real-time picture of the removal of VOCs, enabling RNG plants to be managed more efficiently. Advanced optical absorption spectroscopy technology is used to analyse individual VOC components in a single measurement at sub-ppm level sensitivity and provides a more reliable and cost-effective solution than other technologies, such as Gas Chromatography (GC).
