摘要

Earlier estimates of relative prices of nitrophosphates and urea-ammonium phosphates demonstrated economic advantages for the nitrophosphates. However, inefficient (energy) intermediate processes were postulated then. In the present study, the energy requirements of the two routes are evaluated, using the most energy-efficient-intermediate processes currently available, including cogeneration facilities. Although the nitrophosphate route required about 13% lower total system energy than the urea-ammonium phosphate system, this difference may not be statistically significant. Other factors, such as specific site economics and product acceptability, may override the energy factor. A supplemental and parallel examination of the ammonium nitrate-ammonium phosphate system indicated that such a system would require only one-fourth the energy of two original systems. This result is a strong argument for a rigorous reexamination of the position of ammonium nitrate in the future. (ERA citation 09:010150)
