TLDR
In this article, the authors present a tar sampling protocol for large scale gasification processes, which consists of a heated probe, a particulate filter and a series of impinger bottles.Abstract:
This paper presents tar sampling protocols for pressurised and atmospheric large scale gasification processes Methods for constructing sampling lines either to on-line analysers or into sampling systems are described The tar sampling system consists of a heated probe, a particulate filter and a series of impinger bottles Dichloromethane is used as the tar abosrbing solvent The solvent containing bottles are placed in a cold bath so that gradual cooling of the sampled gas from about 0°C to the final temperature −79°C takes place in them Recommendations for suitable sampling gas flow rates and gas temperatures are given Tar characterisation methods based on different garvimetric measurements and GC analysis are describedread more
