<p>A method for the anti-fouling treatment in petrochemical plants is described, which comprises the washing of hydrocarbons, contaminated by carbonyl compounds, with an alkaline solution comprising an effective amount of a compound according to the general formula (I) as follows: <CHEM> in which X= H, NH2 n= 0 or positive integer number R1, R2, being equal or different from each other, are H, linear, branched or cyclic aliphatic chain C1-C10, or R1 and R2 are joined together to form an aromatic cycle, substituted with the (SO2X)n group if necessary taking care that at least one (SO2X)n group is always present in the molecule and with the exclusion of 4-aminobenzenesulphonic acid; the corresponding salts of formula (I) compounds and the corresponding mixtures.</p> |
