The potential for energy efficiency in the fertilizer industry

This report reviews the potential for energy conservation in the fertilizer industry, describes the organizational aspects of implementing successful energy conservation programs, and gives details of particular conservation measures that may be considered. Since the production of ammonia is the most energy-intensive process for all fertilizer, a major emphasis of the report is on the potential savings in ammonia production, which can amount to as much as 30%, or up to US$ 45/mt of ammonia. About half of the savings can be achieved by good housekeeping measures, with little or no investment cost; the other half involves a mix of short- and medium-term payback investments.
