Method And Apparatus For The Adiabatic Expansion Of Liquid Anhydrous Ammonia
US Patent:
4310555, Jan 12, 1982
Filed:
Oct 19, 1979
Appl. No.:
6/086344
Inventors:
William L. Kjelgaard - State College PA
Paul M. Anderson - State College PA
Paul M. Anderson - State College PA
Assignee:
Research Corporation - New York NY
International Classification:
A23K 122
US Classification:
426 69
Abstract:
Cold anhydrous ammonia, preferably cold liquid anhydrous ammonia at substantially ambient or atmospheric pressure is applied to feed grains, forages and anaerobically fermentable plant material to supply thereto and provide therein non-protein nitrogen (NPN). The cold anhydrous ammonia is obtained by supplying a stream of ambient temperature, pressurized anhydrous liquid ammonia to an expansion chamber for expansion therein to provide the cold anhydrous ammonia. Cold anhydrous ammonia, preferably substantially only cold liquid anhydrous ammonia, is recovered from the expansion chamber operated under substantially adiabatic conditions, at a temperature in the range -30. degree. F. to about -17. degree. F. and at substantially ambient or atmospheric pressure, such as at a pressure in the range 1 pound per square inch below atmospheric pressure up to about 5 pounds per square inch atmospheric pressure.
