The document summarizes reports produced by Intratec comparing the economics of different nitric acid production pathways. The reports analyze capital and production costs of pathways using ammonia, natural gas, heavy fuel oil, or coal as feedstocks. They also examine price trends for nitric acid and raw materials over the past four years and identify the most competitive production alternatives by region. Intratec's methodology involves comprehensive research on production pathways and cost modeling using industrial process data.
