| titleOfInvention | Reduce the system and method producing water consumption in pure terephthalic acid (PTA) |
| abstract | The aqueous stream generated from Production of Terephthalic Acid process reclaims acetic acid, entrainer, extractant, reusable water and other product, and as the apparatus and method of paratolunitrile, it has excellent energy efficiency and the water consumption of minimizing.Described device comprises: the azeotrope tower dewatered from acetic acid, for once reclaiming extractant and other organic a pair mother liquor extraction tower be sequentially connected in series, reclaim the entrainer stripper of entrainer and be separated afterwards solvent stripping destilling tower, it is Separation of Water underflow from described extraction tower further, be isolated into the main organic volatilization logistics comprising and there is little water gaging and the liquid stream comprised containing seldom measuring organic water, every bar stream is enough pure, can be recovered to reuse in the purifying of crude terephthalic acid. |
