| 摘要 |
The invention provides a method for sampling gas in a flue gas stream (31) of an incineration furnace (1) or another CO2-containing gas stream. The method comprises sampling CO2 from the flue gas stream (31) of the incineration furnace (1) and storing CO2 from the flue gas stream (31) in a storage device (5). The storage device comprises a solid, preferably silica- or alumina-based CO2 storage material, which can be regenerated. The method further preferably involves transporting the storage device (5) to an analysis site (10) comprising an apparatus for 14C analysis, retrieving at least part of th stored CO2 from the storage device (5) and determining, based on the 14C analysis, the ratio of biomass-derived and fossil-derived CO2 in the flue gas stream (31).
