A NOVEL UREA GRANULATION PROCESS.

One of the most important claims made for the process is the recycle ratio of less than 0. 5, which makes the process very attractive. Another salient feature of the process described is that the urea solution of 95-97 per cent can be used to granulate urea as against 99. 8 per cent in the other conventional process. There is a saving of energy in the concentration. Another aspect worth noting is the low biuret content of 0. 7 per cent. It is to be admitted that where urea is not used for foliar application the biuret content is not of great consequence, but a product of lower biuret is always preferred. Another feature of this process is that granules ranging from 2 mm to 8 mm can be produced, which is not possible in the prilling process although it can be achieved in granulation process.
