Abstract
A process for producing an aldehyde is disclosed. The process comprises: hydroformylating an olefin to form the aldehyde using a hydroformylation catalyst; recovering an effluent stream comprising the aldehyde, hydrogen and the hydroformylation catalyst; passing the effluent stream to a stripper; contacting the effluent stream with a strip gas in the stripper to produce a stripped effluent stream having a lower hydrogen concentration than the effluent stream; and recovering the stripped effluent stream.
Claims12
A process for producing an aldehyde, the process comprising:
- hydroformylating an olefin in a hydroformylation section to form the aldehyde using a hydroformylation catalyst;
- recovering an effluent stream comprising the aldehyde, hydrogen and the hydroformylation catalyst;
- passing the effluent stream to a stripper;
- feeding a syngas stream to a separation system;
- separating the syngas stream into a hydrogen rich stream and a carbon monoxide rich stream in the separation system;
- and using the carbon monoxide rich stream as a strip gas;
- contacting the effluent stream with the strip gas comprising the carbon monoxide rich stream in the stripper to produce a stripped effluent stream having a lower hydrogen concentration than the effluent stream;
- and
- recovering the stripped effluent stream.
