Abstract
إنتاج أحماض كربوكسيلية أروماتية PRODUCTION OF AROMATIC CARBOXYLIC ACIDS الملخص يتم هنا إعداد طرق وأنظمة للإنتاج المحسن لأحماض كربوكسيلية أروماتية aromatic carboxylic، مثل حمض تيريفثاليك terephthalic acid منقى. وينتج عن الطريقة إستخدام جهاز تقطير distillation device أصغر وذلك لإستخلاص مذيب الحمض الكربوكسيلي carboxylic acid solvent بكفاءة أعلى خلال العديد من مراحل طريقة PTA عند المقارنة بطرق معروفة. ويتم الحصول على جهاز التقطير distillation device الأصغر بإستخدام أجهزة لمعالجة الماء تالية وأجهزة لإستخلاص extraction devices مركب عضوي organic وذلك لفصل المركبات العضوية من تيارات منتجات ثانوية مائية aqueous. شكل 1
