Abstract

يتعلق الاختراع بطريقة من أجل أكسدة الإيثلين ethylene لتشكيل أكسيد الإيثلين ethylene oxide تشمل: توفير تيار مائي محتوي على جليكول الإيثلين ethylene glycol والشوائب؛ إدخال التيار المائي في طبقة معالجة تبادل أيون أولى لتقليل محتوى هذه الشوائب؛ تحديد ما إذا كان خرج طبقة معالجة تبادل الأيون الأولى له موصلية أكبر من حوالي 5 ميكروسيمنز/ سم؛ عند تحديد أن خرج طبقة معالجة تبادل الأيون الأولى له موصلية أكبر من حوالي 5 ميكروسيمنز/ سم، يدخل خرج طبقة معالجة تبادل الأيون الأولى في طبقة معالجة تبادل أيون ثانية؛ وعند تحديد أن خرج طبقة معالجة تبادل الأيون الأولى له موصلية أكبر من 60 ميكروسيمنز/ سم، يعاد توجيه إدخال التيار المائي إلى طبقة معالجة تبادل الأيون الثانية وتجديد طبقة تبادل الأيون الأولى.
