Abstract
Process and economic advantages are achieved by the integration of a Fischer Tropsch process for hydrocarbon liquids production as a retrofit in an installation for the production of ammonia fertilizer from fossil fuel derived syngas. Utilization of most of the CO and part of the H2 in the syngas stream during Fischer-Tropsch synthesis as the first step in the integrated process produces hydrocarbon products while the F-T effluent containing unreacted hydrogen gas at the necessary ratio of H2/N2 is used in the second step of ammonia synthesis. The overall product slate as appropriate for maximum economic performance of the installation is thus achieved.
