titleOfInvention | Carboxylic acid absorption from vaporous aqueous streams |
abstract | The invention provides a process for the recovery of C 3 -C 6 carboxylic acid from a vaporous aqueous stream, comprising providing a vaporous aqueous stream comprising C 3 -C 6 carboxylic acid, contacting said vaporous aqueous stream comprising C 3 -C 6 carboxylic acid with an absorbing solvent in an absorption unit, to produce a first stream comprising absorbing solvent and C 3 -C 6 carboxylic acid and a second stream comprising water vapour, feeding said first stream comprising absorbing solvent and C 3 -C 6 carboxylic acid to a solvent recovery unit, to produce a third stream comprising C 3 -C 6 carboxylic acid and a fourth stream comprising absorbing solvent, and optionally recycling at least a portion of the fourth stream comprising absorbing solvent to the absorption unit, wherein the absorbing solvent is an oxygen-containing organic compound having (i) a Hansen solubility parameter distance R a with respect to C 3 -C 6 carboxylic acid as determined at 25°C of 15 MPa 1/2 or less, preferably 12 MPa 1/2 or less, more preferably 10 MPa 1/2 or less; (ii) a 1-octanol/water partition coefficient logP OW as determined at 25 °C and pH 7 of at least 0, preferably at least 0.5, more preferably at least 1.0, even more preferably at least 1.5, yet even more preferably at least 2.0, most preferably at least 3.0; and (iii) a boiling point at atmospheric pressure that is at least 5 °C higher, preferably at least 10 °C higher, more preferably at least 20 °C higher than the boiling point of the C 3 -C 6 carboxylic acid. |
