Macrotek Wins Additional Contract in Ammonia Removal and Recovery Systems

International air pollution control provider, Macrotek Inc., has announced the award of a multi-million dollar contract for phase one engineering for one of the world’s largest ammonia and urea producers in Trinidad.

Macrotek’s innovative design will control ammonia emissions and generate a valuable, usable by-product.

Phase one of the systems includes the collection of fugitive ammonia vapours from tank vents. A two-stage scrubber will convert the ammonia into a high purity ammonium salt by-product which is also generated in other parts of the plant. The conversion of ammonia to ammonium salt will be accomplished using acid as the reagent. Using this strategy, ammonia emissions are reduced and recovery is optimized. The package will be skid-mounted, pre-wired and pre-piped to minimize fieldwork and installation time.

The by-product will be blended with ammonium salt solutions generated in other parts of the plant. A key consideration in Macrotek’s design is ensuring the generated by-product meets plant specifications for concentration and pH.

The project is currently in detailed engineering with estimated delivery in the first quarter of 2019.
