Development of Technology in the Production of Fertilizers in Ammoniation-Granulation Plants. Progress Report No. 12, September 1980. Final Report

摘要

Work conducted to demonstrate procedures and equipment to conserve about 83% of fuel oil used for drying and generating steam in the ammoniation-granulation plants is reported. The general mechanism of granulation is examined. Conventional ammoniation-granulation plants are described and the new pipe-cross reactor system is described and schematics of their design are presented. Results of some demonstration tests reveal that an average of 785,000 Btu's per ton of production is eliminated with the installation of the TVA pipe-cross reactor process. It also reduces atmospheric emissions. Data on investment cost and payback period of the installation of a pipe-cross reactor in an existing TVA granulation fertilizer plant are presented.
