Abstract

يتعلق الكشف الحالي بعملية لإنتاج حمض اسيتيك acetic acid وفيها يتم سحب مخرج سحب جانبي بخاري vapor sidedraw من العمود الثاني second column في سلسلة التنقية الأولية primary purification train. يتضمن مخرج السحب الجانبي البخاري vapor sidedraw حمض اسيتيك acetic acid ومركبات تشتمل على ليثيوم lithium بتركيز لا يتعدى 100 جزء وزن لكل بليون Weight Parts Per Billion (wppb). كما يتم سحب تيار مواد مترسبة غني بمركبات تشتمل على الليثيوم lithium ، مثل اسيتات ليثيوم lithium acetate ، أو داي هيدرات اسيتات ليثيوم lithium acetate dihydrate ، من العمود الثاني second column. على نحو ملائم ، يتم تغذية مخرج السحب البخاري vapor sidedraw ، أو قسم مكثف منه، مباشرة إلى راتين resin تبادل أيوني ion يحدث به استبدال بفلز metal به مواقع تبادل كاتيوني حمضي acid cation للحصول على حمض اسيتيك منقى acetic acid. هذا يمنع استبدال الفلزات metals في راتينج التبادل الأيوني ion exchange resin. شكل 1.
