To save space, improve process and reduce maintenance in critical heat exchanger duties:
Challenge
- Ammonia stripper vent condensers
- Weak nitric acid coolers
- Stripper condensate exchangers/economizers
- High-pressure condensate preheaters
- Ammonia shift condensers
Solution
Tranter SUPERMAX® Shell & Plate Heat Exchangers in ammonia, nitric acid and urea manufacturing.
Results
- A smaller footprint, lower cost and simplified mechanical cleanability as desulfurization and CO2 capture lean/rich interchangers
- Smaller footprint and a significant improvement in the temperature approach of 9°C (16°F) as 4-unit, manifolded, multi-pass, high-pressure condensate preheaters vs. triple series-piped shell & tube heat exchangers
- Improved product life as weak nitric acid coolers (compared to shell & tube units)
- Better leak resistance as ammonia stripper vent condensers (compared to block-type welded exchangers)
- Reduced maintenance burdens
