Detailed Report Utility & Unit Consumption Ammonia ton/ton product (100% base) Power 250 KWH/ton product Boiler feed water 980 lbs/ton product Cooling water 70° F - 85° F cubic meter per ton / (circulation) Steam (credit) export 750 lbs/ton of acid Platinum, net burnt Troy ounce/ton of acid Total catalyst weight 500 Troy ounces/charge. NOx exit extended absorption column Less than 550 PPM
Major Components Equipment Compressor Train Brown Bravery Corporation, Electrical motor driven, Gear box Ammonia Converter 36.5 inches Hex Catalyst support Heat Train Expander Re-heater Air heater W.H. Boiler and the economizer/boiler feed water pre-heater Cooler Condenser Cascade type 4” coil and 432 S.S Absorption Columns Absorption Extended absorption column (NOx column) Added in 1987 and reduced the tail gas making slight changes to the process a NOx level of less than 200 PPM can be achieved.
