Online Quantification of Tar during Biomass Gasification



Biomass gasification constitutes a low carbon technology and renewable energy source for the production of syngas. Tar containing benzene, toluene and xylene (BTX) as well as polycyclic aromatic hydrocarbons (PAHs) is an unwanted by-product that can saturate the cleaning system and degrade the catalyst employed for fuel production. For process optimization and prevention of tar formation continuous online measurements are vital.


Quantification of tar formation can be achieved by Ion Molecule Reaction Mass Spectrometry (IMR-MS). V&F provides compact IMR-MS solutions that can be connected directly to the exhaust of a biomass gasification facility via a heated capillary. BTXs and PAHs can be monitored at low (ppb) or medium (ppm) concentration levels. Variations in contaminant concentrations are detected immediately and results can be transmitted via communication devices.


V&F systems are versatile mass spectrometers facilitating real time online measurements of BTX and PAH contaminants with a high precision. Without the need sampling or sample preparation the equipment offers remote control and intra- / internet capabilities. Immediate result reporting allows for continuous process monitoring and timely adjustment of parameters to prevent contamination.
