Abstract

يكشف الطلب الحالي عن طريقة جديدة للتحكم في تشكيل البيوريت biuret عند إنتاج اليوريا urea. ويتم تحقيق ذلك عن طريق تقليل أو منع تشكل البيوريت في قسم التكثيف concentration section ، خاصة في واحد أو أكثر من المكثفات أو المبخرات evaporators. تشتمل الطريقة على التحكم في وقت بقاء residence time تيار اليوريا المائي urea aqueous stream المُعالَج في قسم التكثيف هذا بطريقة مستقلة عن التدفق الحجمي volume flow للتيار المذكور في قسم التكثيف المذكور، لكل فترة زمنية. يمكن التحكم في وقت البقاء، على سبيل المثال، عن طريق توفير قسم التكثيف مع إمكانية ضبط حجمه أو عن طريق إضافة غاز gasإلى تيار اليوريا urea stream الذي يتم معالجته. يمكن أيضًا تطبيق مجموعة من هذه التدابير. شكل 1.
