  • PROCESS FOR SEPARATING HEAVY BY-PRODUCTS AND CATALYST LIGAN FROM A VAPOUR STREAM COMPRISING ALDEHYDE
    Publication number: 20240051908
    Abstract: A process for separating heavy by-products and catalyst ligand from a vapour stream comprising aldehyde, the heavy by-products and the catalyst ligand the process comprises passing the vapour stream to a fractionator in which the vapour stream is contacted with liquid aldehyde which removes at least a portion of the catalyst ligand and at least a portion of the heavy by-products from the vapour stream, recovering a liquid bottom stream, comprising removed catalyst ligand from the fractionator; recovering a scrubbed vapour stream from the fractionator, condensing a first portion of the scrubbed vapour stream to create the liquid aldehyde, and recovering a second portion of the scrubbed vapour stream as a product aldehyde stream. The liquid bottom stream is passed to a separation system to separate some aldehyde from the liquid bottom stream to create a recovered aldehyde stream, comprising the separated aldehyde.
