ABSTRACT
The ammoniation, water, and heat balances require further consideration because they are less easily calculated and are directly related to the actual granulation process. If it is assumed further that granulation takes place around 200 F, it is possible to relate moisture requirements for granulation with the amount of ammonium nitrate present in the formulation. The major reason for calculating a heat balance is to ensure that materials will be brought to a temperature high enough for good granulation. If the heat balances calculated in these two ways agree within 36,000 BTU, satisfactory granulation temperatures can generally be expected. The only problems to solve are the heat release and the water needed for granulation so we will work only with the solution, the phosphates and sulfuric acid.
