Abstract
A process for the hydroformylation of olefins to aldehydes is disclosed. The process comprises: hydroformylating one or more olefins with hydrogen and carbon monoxide in the presence of a ligand-rhodium catalyst in a reaction zone; recovering a reactor effluent from the reaction zone, the reactor effluent comprising product aldehyde and the ligand-rhodium catalyst; passing the reactor effluent and a strip gas to a vaporiser, wherein the strip gas comprises carbon monoxide and is formed from a recycle strip gas stream and a make-up strip gas stream, wherein the product aldehyde is vaporised into the strip gas in the vaporiser resulting in a vapour mixture, comprising the strip gas and the product aldehyde, and a liquid mixture, comprising the ligand-rhodium catalyst; recovering the liquid mixture and recycling the ligand-rhodium catalyst to the reaction zone; recovering the vapour mixture and separating the product aldehyde from the vapour mixture.
