A Tar Online Measurement System Based on the Absorption Principle

D. Roveda, T. Kienberger, M. Grigiante & J. Karl
Within this work, a very simple but yet fully effective and cheap online measuring system has been tested and evaluated. The analytic method is based on the optical absorption principle. The syngas produced from a lab scale fluidized bed gasifier and post-processed in a methanation reactor has been continuously online monitored and analyzed into an optical measurement cell. In this cell, called TOM (Tar Online Measuring), a UV light stream is produced employing LEDs operating...
