Abstract
An improved process and apparatus integrate a deethanizer column with a cryogenic heat exchanger by condensing the deethanizer column overhead with a refrigerant stream in a cryogenic heat exchanger. A refrigerant compressor may provide refrigerant to the deethanizer overhead cryogenic condenser and a main cryogenic heat exchanger. Expansion of the refrigerant may provide sufficient cooling duty in one or both cryogenic exchangers.
