Abstract
In the simultaneous neutralization and drying of ammonium sulphate by treating it with a current of ammonia gas and heated air, the used gases are passed to apparatus of known type in which the excess ammonia and pyridine are separated by treatment with acid. Specification 108,098, [Class 1 (ii), Inorganic compounds, other than &c.], is referred to.
