Abstract

See full text

To produce fertilizer, a system and method concentrates manure slurry in a mechanical vapor recompression evaporator (“MVR”) having a heat exchanger. The MVR receives the manure slurry within a first side to evaporate ammonia laden-water vapor from the slurry, leaving a nutrient concentrate. A compressor raises the evaporated ammonia-laden water vapor to a higher energy state. Within a second side of the heat exchanger, the compressed water vapor conveys heat to the slurry. Ammonia-laden water condenses in the second side at a process temperature to be conveyed to an ammonia stripping tower where the ammonia-laden water is dispersed into ammonia-laden water droplets. In the tower, a flow of air is directed across a surface of the ammonia-laden water droplets, the process temperature having been selected to promote the escape of ammonia gas from the ammonia-laden water droplets, the flow of air provided to entrain ammonia gas in the flow.
