  • Ammonia absorption process
    Patent number: 4119412
    Abstract: A process is disclosed whereby a gas stream from the process for the manufacture of a morpholine compound by the catalytic reaction of a dialkylene glycol with ammonia to form a morpholine compound in the presence of hydrogen is disclosed. The ammonia is scrubbed from the gas stream by using the dialkylene glycol feedstock as the scrubbing fluid. Thus dry hydrogen can be repressurized and used in the process as can the ammonia in the feedstock stream.
    Type: Grant
