| titleOfInvention | Recovery method of terephthalic acid |
| abstract | The present invention relates to a method for recovering terephthalic acid, and more particularly, after hydrogenation of crude terephthalic acid and precipitation of terephthalic acid through a crystallization process, recovering terephthalic acid precipitated in the first solid-liquid separation process, the remaining mother liquor is 50 ~ 90 It is about a terephthalic acid recovery method characterized by cooling to ℃ and separating the precipitate using a solid-liquid separator. According to the terephthalic acid recovery method of the present invention, it is possible to efficiently recover the terephthalic acid contained in the mother liquor to be treated with waste water, thereby improving the yield of terephthalic acid and reducing the wastewater treatment load. |
