Technofrigo by Clauger delivered a complete process refrigeration system for a major North American petrochemical client producing ammonia. This turnkey installation provides multi-level cooling for process applications while safely handling boil-off gas from ammonia storage tanks — a critical requirement for continuous plant operations in high-ambient-temperature conditions.
We worked directly with a major engineering and petrochemical group delivering technology, engineering, procurement and construction for synthesis gas, air separation, petrochemical plants, and fluid processing for refineries.
Industrial ammonia storage requires large, low-pressure tanks maintained at low temperatures. In high-temperature seasons, heat transfer to storage tanks creates vapour or boil-off gas. Without proper management, this results in product loss, safety concerns and operational inefficiencies. Active refrigeration — not tank insulation alone — is essential for reliable operations.
The client required a full-scale refrigeration system supplying cooling at three precise temperature levels to support ammonia production and storage operations, plus safe handling of vapour from storage tanks.
We engineered a complete ammonia-based refrigeration system integrating process cooling with boil-off-gas handling — delivering reliable performance across all operating conditions including extreme temperatures.
The process refrigeration system features three oil-flooded screw compressors operating at three different pressure levels.
The dedicated BOG system safely handles vapour streams from ammonia storage.
Three-level cooling ensures continuous ammonia production operations through the year.
BOG condensation eliminates ammonia losses from storage tanks during high-ambient periods.
Proper vapour management reduces pressure risks in ammonia storage operations.
System handles normal operations and plant shut-down scenarios reliably.
Proven effective in demanding ambient conditions where other systems struggle.
Ammonia-based system provides efficient, cost-effective cooling — ideal for plants already handling NH₃.
