  • Ammonia storage and injection in NOx control
    Patent number: 6852292
    Abstract: A system is described for storing ammonia and injecting it into the exhaust gas stream of an engine to reduce nitrogen oxides. The ammonia is stored as a liquid mixture (70) of ammonia and water in a container (50). In one system, the mixture passes through a tube with a portion (62) in contact with the exhaust gas pipe (16) to heat the mixture and separate the ammonia from the water, with the ammonia being further heated at a nozzle (84) to activate the ammonia before injection into an upstream portion of the exhaust gas pipe.
