Online quantification of tar during biomass gasification

Background

Biomass gasification represents a renewable energy source for the production of synthetic natural gas. Tarry benzene, toluene, and xylene (BTX), as well as polycyclic aromatic hydrocarbons (PAHs), are undesirable by-products. These saturate the filtration system and promote the degradation of the catalyst used for fuel production. Continuous on-line measurement is essential for process optimization and prevention of tar formation.

Solution

Quantification of tar formation can be achieved by ion molecular reaction mass spectrometry (IMR-MS). V&F offers compact IMR-MS solutions that can be directly connected to the exhaust gas of a biomass vaporization system via a heated capillary. BTXs and PAHs can be measured in low (ppb) and medium concentrations. Deviations in impurity concentrations are detected immediately and results can be transmitted via interfaces.

Advantages

V&F systems are convertible spectrometers that provide real-time, on-line measurements of BTX and PAH impurities with high accuracy. No sampling or sample preparation is required, and the instrument offers remote intra- and internet control capabilities. Instant result display allows continuous process monitoring and timely adjustment of parameters to prevent contamination.

Highlights

  • Real-time measurement of BTX and PAH
  • No sample preparation
  • Process monitoring
