Abstract
The present invention relates generally to hydroformylation processes. In one embodiment, a process of the present invention comprises: (a) contacting CO, H2, and at least one olefin under hydroformylation conditions sufficient to form at least one aldehyde product in the presence of a hydroformylation catalyst; (b) removing a product-containing liquid from the reaction zone and sending it to a vaporizer, which comprises a vaporizing zone and a vapor/liquid separation zone, wherein the product-containing liquid, which comprises crude product and catalyst, is heated in the vaporizing zone to form a mixture of gas and catalyst-containing liquid, which mixture is then phase separated in the separation zone, which separation zone has a liquid withdrawal port, a liquid region, a vapor space and a gas-liquid interface, wherein the liquid region comprises at least one divider plate, which optionally contains at least one perforation, wherein at least a portion of at least one divider plate is in proximity to the gas-liquid interface, with the proviso that at least a portion of at least one divider plate is at or below the interface, and wherein the temperature of the catalyst-containing l…
