Abstract
Systems and methods for purification of ammonia from an ammonia liquid feed stream, particularly ammonia recovered from a 2-column SWS unit, by vaporizing the ammonia liquid feed stream to produce a very cold (potentially subzero) ammonia vapor stream and passing the cooled ammonia vapor stream through an adsorption media such as activated to remove impurities from the cooled ammonia vapor stream and produce a purified ammonia vapor stream.
Claims20
A system for purifying ammonia, comprising:
- an ammonia liquid feed stream;
- a valve fluidly connected to the ammonia liquid feed stream and a cooled ammonia vapor stream for vaporizing the ammonia liquid feed stream and producing the cooled ammonia vapor stream;
- and
- a vessel comprising an adsorption media in fluid communication with the cooled ammonia vapor stream for removing impurities from the cooled ammonia vapor stream and producing a purified ammonia vapor stream.
