  • Ammonia recycling still for a refrigeration system and method therefor
    Publication number: 20070022764
    Abstract: An ammonia still apparatus of the invention is used to reclaim ammonia from contaminated ammonia refrigeration fluid in an ammonia refrigeration system. The ammonia still apparatus is used in fluid communication with the ammonia refrigeration system and can be run manually or automatically using an electronic controller, such as a programmable logic controller. The ammonia is separated from the contaminated refrigeration fluid after heating the fluid with a heat exchanger. The reclaimed ammonia is returned to the ammonia refrigeration system where it is reused. Waste fluid from the ammonia still apparatus is collected and dumped.
