overview
Overview

The process begins with compressed air at 135 psig and at 540° F. The air is mixed with superheated ammonia and flows through the Burner where the ammonia is catalytically (platinum catalyst) oxidized to produce Nitrogen Oxides. The process gas leaves the ammonia burner at about 1650° F and passes in succession through the expander turbine re-heater, the waste heat boiler, platinum filter, tail gas heater,

boiler feed water pre-heater, process gas cooler and ultimately the cooler condenser prior to enter the absorption column. In the absorption column the Nitrogen Oxides react with process condensate

produce Nitric Acid. The tail gas which is mainly Nitrogen exits the top of the absorber, passes through a series of exchangers before reaching the expander gas

turbine for power recovery prior to be realized to the atmosphere. The gas expander/ recovery turbine at normal operation provides about 80% of

the required power to run the air compressor.

Note:A second absorption column was added at down stream of original absorption column to mitigate the NOx emission to the atmosphere. After this improvement the NOx content of the tail gas dropped to 200 ppm plus/minus.
