| titleOfInvention | Method for extracting isophthalic acid-5-sodium sulfonate from three-monomer production wastewater |
| abstract | The method for extracting isophthalic acid-5-sodium sulfonate from the three-monomer production wastewater consists of a precipitation crystallization tank (A), a filter press (B), an ester decomposition tank (C), a high-pressure pump (D), and a distillation Tower (E), decolorization and adsorption kettle (F), filter (G), concentration and crystallization kettle (H), centrifugal dehydrator (I), heat melting kettle (J), fine filter (K), secondary concentration and crystallization The kettle (L), the rubber-lined dehydrator (M), and the dryer (N) are connected to form a production line. The three-monomer production wastewater (I) is used as the main raw material. Add organic precipitant (2), sodium hydroxide (6), activated carbon (9), deionized water (16), sulfuric acid (17) and activated carbon (9), in the specific temperature, time and process conditions of each process process Next, make the finished product (24) of sodium isophthalic acid-5-sulfonate. The present invention can also extract the sodium sulfate crystals (4) in the waste water. Reduce pollution, protect the environment, turn waste into wealth, kill two birds with one stone. |
