NITROGEN PRODUCTS PRODUCTION AND CONSUMPTION

Capacity, Production, and Consumption. Ammonia production has worldwide significance about 85% of the ammonia produced is used for nitrogen fertilizers. As the primary source of fertilizer nitrogen, it is key to solving world food production requkements. The remaining 15% goes into various industrial products such as fibers, animal feeds, explosives, etc.

Figure 3.7 illustrates the importance of North America and Asia in the production and consumption of nitrogenous fertilizers. The surplus of production over consumption in the FSU and the Middle East illustrates then-importance as exporters36. 

In that process, a large quantity of ammonium sulfate is produced, and it is used in fertilizers because it is a relatively inexpensive source of nitrogen. Finally, a large quantity of sulfuric acid is used as the electrolyte in millions of automobile batteries. With so many processes that consume enormous quantities of H2S04, it is not surprising that the production and consumption of sulfuric acid provides a barometer to the general health of the economy ...

Figure 12 Major reduction-oxidation reactions involving nitrogen. The reactions are numbered as follows (1) mineralization, (2) ammonium assimilation, (3) nitrification, (4) assimilatory or dissimilatory nitrate reduction, (5) ammonium oxidation, (6) nitrite oxidation, (7) assimilatory or dissimilatory nitrate reduction, (8) assimilatory or dissimilatory nitrite reduction, (9) denitrification, (10) chemodenitrification, (11) anaerobic ammonium oxidation, and (12) dinitrogen fixation (after Capone, 1991) (reproduced by permission of ASM Press from Microbial Production and Consumption of Greenhouse Gases Methane, Nitrogen Oxides, and Halomethanes, 1991).

Frank and Hirano (1990) survey the potential for the production and consumption of alternative, usable, commercial byproducts in conjunction with a major reduction in national emissions of SO2 and NO,. Hiey conclude that the potential byproduct yields from the U.S. acid rain control program greatly exceed available markets for the chemical products. Byproducts evaluated in the study include gypsum, sulfuric acid, ammonium sulfate, ammonium sulfate/nitrate, and nitrogen/phosphorous fertilizer. Henzel and Ellison (1990) present a review of past, present, and potential future disposal practices and commercial FGD byproduct utilization. Hiey indicate that the only discemable trend is the production of usable gypsum by wet FGD systems. The 1990 Clean Air Act Amendments may create a need for disposal sites, which tend to be expensive and scarce and which could in themselves be environmental problems. Systems that produce usable byproducts are expected to become more important in the future as the disposal option becomes less viable.
