Description
This Weatherly High Pressure Nitric Acid Plant is designed for large-scale nitric acid production, with an original capacity of 500 STPD and proven operational output of 535 MTPD. The plant offers a turn-down ratio of 88%, providing operational flexibility to adjust production levels as needed. Ammonia consumption is 0.304, demonstrating efficient conversion for high yield nitric acid production.
Key components include a five-stage Ingersoll-Rand centrifugal air compressor, capable of 49,453 SCFM (dry) at 14.7 psia and 60°F, and an Ingersoll-Rand E-4331 hot gas expander. The compressor train was rebuilt in 1994, significantly extending its operational life.
The system has been upgraded and maintained, including:
New economizer, high-pressure intercooler, and low-pressure intercooler
Surface condenser and high-pressure filter
Absorber column: 12' diameter x 66' height, with 18 absorption trays and 4 bleaching trays
New cooler condenser (installed in 2003)
New surface condenser (details incomplete)
This nitric acid plant is a complete, ready-to-install solution for fertilizer, chemical, and explosives production operations.
