There are two units (three lines) of Nitric Acid production. The old line has a capacity of 180 MTPD of 60% Nitric Acid strength. This line commenced production in 1963. Other two lines have a capacity of 600 MTPD of 60% Nitric Acid. These two lines commenced production in December, 1978.
The old line was modified in 1986 when an additional Absorption Tower was added, which resulted in increase of Nitric Acid concentration to 60% strength and reduced pollution level i.e. NOx Emission from 4000-6000 mg/cubic meter to 800 mg/cubic meter. The plant is operated as and when required.
The two new lines have on stream factor of 330 days (originally 320 days). The old line consumes 0.310 MT Ammonia/ton Nitric Acid (100% basis) while the new lines consume 0.290 MT Ammonia/ton of Nitric Acid (100% basis). Thus old unit of Nitric Acid consumes higher energy.
Approximately 40% of total Ammonia produced is used to produce Nitric Acid.
