Tar-Analyzer TA120-3 (discontinuation)

Application

 The Tar Analyzer TA 120-3 is designed for quasi-continuous on-line measurement of the Tar content in gas from Biomass Gasification. The use of this measurement system is distinguished from the conventional "wet-chemical" methods of measurement through a series of improvements. It convinced the users especially the possibility of simultaneous and quasi-continuous measurement of Tar, Aromatics and Total Hydrocarbon content for fast optimization of process parameters. In principle, the TA 120-3 also be used for other measuring tasks where high-boiling and more volatile Hydrocarbon groups should be measured separately.

Tar-Analyzer TA120-3

Function

The hot Sample Gas from the Gasifier is sucked into the Analyzer by a Venturi Pump and distributed into three Sample Loops over inbuilt Dust Filter. The content of the Loops is flushed by the Carrier Gas to the FID Detector sequentially. The first and the second Loop Content passing a cooled Filter Section. Each Section can be set to the condensing Temperature of the Type of Tar to be eliminated on this Sample Volume. The third Loop Content is flushed to the Detector containing the original Sample Gas from the Gasifier.

After running the Measurement Cycle, the Values of the different Concentrations are calculated by the Control and Monitoring Software of the Analyzer TA120-3.

The Controller Functions of the TA120-3 Software (TA 120 DataAquisition©) can by also performed manually from the Keyboard on the Analyzer Front Panel.
