Method for treating oxygenated volatile organic compounds in Fischer-Tropsch synthesis reaction water
The invention relates to a method for treating oxygenated volatile organic compounds in Fischer-Tropsch synthesis reaction water. Fischer-Tropsch synthesis reaction water is subjected to (a) primary concentration and separation, (b) carbonyl compound hydrogenation, (c) carbonyl compound cutting, (d) mixed-alcohol dehydration, (e) solvent recovery, (f) ethyl alcohol separation, (g) methyl alcohol removal and separation, (h) isopropanol separation, (i) propyl alcohol cutting, (j) n-propyl alcohol separation, and (k) 2-butanol separation, so that basic organic chemicals such as ethyl alcohol, isopropanol, n-propyl alcohol, 2-butanol and mixed alcohols are obtained. Compared with the prior art, the method directly converts the concentrated Fischer-Tropsch synthesis water rich in alcohols, aldehydes, ketones, acids, and esters into a mixed-alcohol solution by hydrogenation, thus having the advantages of simple separation process and high product purity.
