Abstract: A method for the production of a urea ammonium sulphate (UAS) composition in a pipe reactor comprising at least a reactor section, the method comprising:
combining in the reactor continuous feeds of at least one of sulphuric acid and ammonium bisulphate, at least one of ammonia and ammonium carbamate, and urea; and
including a viscosity-reducing agent selected from water soluble aluminum salts in at least one of the continuous feeds, thereby forming the urea ammonium sulphate (UAS composition, wherein the UAS composition comprises 1 to 40 weight % of ammonium sulphate (AS) relative to the total weight of the UAS composition.
