Isotopic study of CO2 from industrial off-gases emission

The monitoring of greenhouse gases originating from different sources will be a crucial problem during this century. Experiments have been performed in order to obtain stable isotope composition of CO2 emitted by large industrial off-gas emitters. A special set for sample collection in field conditions was designed and tested. Two different methods of CO2 extraction were elaborated: vacuum extraction and extraction with carrier gas. Preliminary results of CO2 stable isotope composition emitted from an electric power plant during one working season are presented.
