Abstract

In the manufacture of ammonium sulphate the paste of crystals discharged from the saturator is allowed to drain under conditions which prevent further crystallization during the draining process. Preferably the paste is discharged into a closed draining-vessel, which is heated to a temperature not above that of the crystals. The process may be carried out in conjunction with that described in Specification 152,766, for improving the colour of ammonium sulphate.
