Abstract: A process of recovering propylene and N-butyraldehyde from a purge gas includes forming a first product stream including N-butyraldehyde by reacting propylene and a first synthesis gas in the presence of a first catalyst in a first reactor and a second reactor; withdrawing a mixed stream from the second reactor; separating a liquid stream and purge gas from the mixed stream and recycling the liquid stream to the second reactor; reacting the purge gas and a second synthesis gas in the presence of a second catalyst in a purge gas reactor to form a second product stream including N-butyraldehyde; withdrawing the second product stream including N-butyraldehyde from the purge gas reactor and combining the second product stream including N-butyraldehyde and the first product stream including N-butyraldehyde; and withdrawing a stream including N-butyraldehyde from the purge gas reactor and recovering N-butyraldehyde from the stream including N-butyraldehyde product stream.
