A hydroformylation system for making aldehydes includes: (a) a primary reactor provided with catalyst feed, syngas feed and olefin feed adapted to convert the olefin and syngas to product aldehyde; (b) a first liquid vapor separator coupled to the primary reactor for receiving output therefrom, adapted to separate the product aldehyde into a crude aldehyde product stream and a vent stream containing syngas and unreacted olefin; (c) a vent reactor coupled to the first liquid vapor separator to receive the vent stream therefrom, the vent reactor also being coupled to the primary reactor which is configured to provide catalyst thereto, wherein the vent reactor is operative to convert unreacted olefin in the vent stream from the first liquid vapor separator to additional product aldehyde. A second liquid vapor separator is coupled to the vent reactor to receive output therefrom and adapted to separate the output from the vent reactor into a liquid recycle stream containing additional product aldehyde and catalyst as well as another vent stream, the second liquid vapor separator also being coupled to the primary reactor so as to provide the recycle stream thereto.
