Abstract

Due to the increasing number of different online and offline methods and procedures for sampling at gasification and pyrolysis plants a comparison of the measured values is difficult. About the sampling of tars already a number of detailed guidelines and a common approach are established [2]. In terms of discrete chemical impurities the missing of a guideline for sampling at biomass¬ plants is an obstacle for implementing sampling systems in new plants or experimental assemblies. Nevertheless the knowledge is available at several institutions but it has to be collected. Within this paper the basic challenges of sampling are mentioned, the system at Bioenergy2020+ is explained in detail and about the parameters NH3, H2S & HCN useful results of optimisation are reported. This status should help to point out the need of a reliable library of methods. According the first systematisation of offline and online sampling respectively detection a table of application is proposed. The detailed knowledge for this will be treated and exchanged within an established working group which should lead to a guideline (at least methods library) for sampling of trace components as described.
