| titleOfInvention | Process for the recovery of aldehydes obtained from the hydroformylation of olefins in two columns of increased pressure |
| abstract | A method for separating the aldehyde and the second component from a feed stream (3a, 3b, 3c) comprising the aldehyde and the second component, said method comprising: providing the feed stream to a In one or both of a first separation vessel (1) and a second separation vessel (2) operated at a second pressure, wherein said second pressure (2) is greater than said first pressure; operating said first separation vessel (1) and said second separation vessel (2) so that separation occurs; an aldehyde product stream (4) is recovered at or near the bottom of the first separation vessel (1), said aldehyde product stream (4 ) has an aldehyde concentration higher than that of the feed stream (3a, 3b, 3c); a second component stream (8) is recovered from or near the top of the second separation vessel (2), said second component The second component concentration of the stream is higher than the second component concentration of the feed stream (3a, 3b, 3c); the first recycle stream (5, 6) and feed it to the second separation vessel (2); and remove the second recycle stream (9, 10) from or near the bottom of the second separation vessel (2) and feed it to the first Separate container (1). |
