| titleOfInvention | PROCEDURE FOR THE ABSORPTION OF FORMALDEHYDE FROM A GAS CONTAINING FORMALDEHYDE AND WATER VAPOR |
| abstract | Procedure for the absorption of formaldehyde from a gas containing formaldehyde and water vapor, under the formation of a concentrated solution containing formaldehyde and phenol, in an absorption system of more than one phase, characterized in that in a first phase the The gas is brought into contact with a circulating absorption solution containing, in addition to 5-50% by weight of water, 1-10 mol of formaldehyde per mol of phenol, the contact of which is carried out under continuous evacuation of part of this circulating solution as product to be obtained in an amount such that per unit of time the product evacuated contains an amount of formaldehyde that equals the quantity supplied of formaldehyde gaseiforme, after which the formaldehyde that has not been absorbed in the first phase is absorbed in a final phase of countercurrent absorption to water that is supplied continuously, adding to the resulting diluted solution of formaldehyde both phenol by u time as the final phase of absorption in the form of product obtained is finally evacuated, after which the mixture obtained from formaldehyde-phenol and water is supplied, as a substitution, to the absorption liquid circulating through the first absorption phase.
