In the Skoglund process the gases and vapours from the still are made topass up a reaction tower and then up a condenser instead of down. Theresult of this is that the oxides of nitrogen are removed almost completelyfrom the condensed nitric acid. The plant is used in many explosives factoriesin North America and in several French dynamite Processes for the continuous or semi-continuous manufacture of nitric-acid have also been In the retort a certain proportion of the nitric acid is always reduced Recovery ofthrough various causes to lower oxides of nitrogen.
