The purpose of this project is to study the fate of the nitrogen bound in inorganic smelt leaving the recovery boiler.Of special interest is to find out which forms the nitrogen takes in the process and in which forms it finally leaves the recovery cycle, and what are the potential main exit points for nitrogen in the process.
