تركيب التعبئة في برج امتصاص وفصل إيثيل بنزين

2025-06-27

عادةً ما تختار أبراج امتصاص وفصل إيثيل بنزين مواد التعبئة المناسبة بناءً على متطلبات عملية الفصل وخصائص المواد (مثل فرق نقطة الغليان بين إيثيل بنزين والمكونات الأخرى والتآكل واللزوجة وما إلى ذلك) وظروف التشغيل (مثل درجة الحرارة والضغط وقدرة المعالجة). تشمل الأنواع الشائعة من مواد التعبئة ما يلي:

1. تتميز عبوات packing

Structured المنظمة بهيكل منتظم وترتيب أنيق ، مع كفاءة نقل كتلة عالية ، مما يجعلها مناسبة للسيناريوهات ذات متطلبات دقة فصل عالية. زيادة مساحة نقل الكتلة ، وتوزيع السوائل المنتظم ، والمقاومة المنخفضة ، ومعدل التدفق العالي. سيناريوهات

Applicable: في فصل إيثيل بنزين ، إذا كانت لزوجة المادة منخفضة ، فلا توجد مقاومة قوية للتآكل ، ويلزم كفاءة نقل الكتلة العالية (مثل فصل إيثيل بنزين عن البنزين والتولوين) ، غالبًا ما يتم اختيار هذا النوع من التعبئة.

Advantages: كفاءة فصل عالية ، يمكن أن تقلل من ارتفاع البرج ، وتوفر مساحة الأرضية.

Advantages: مناسبة لسيناريوهات إيثيل بنزين ، مع مساحة سطح كبيرة محددة ، وكفاءة نقل كتلة عالية للغاية ، وتعطيل سائل صغير ، ومقاومة منخفضة. سيناريوهات

Applicable: مناسبة لسيناريوهات الإيثيل بنزين الفصل مع متطلبات نقاء عالية للغاية (مثل تنقية المنتجات الكيميائية الدقيقة) ، أو عندما تكون قدرة المعالجة صغيرة ولكن يلزم دقة فصل عالية. ملاحظات: تكلفة أعلى. إذا كانت المادة تحتوي على جزيئات أو عرضة للقاذورات ، فقد تتسبب في انسداد ويجب استخدامها بحذر.

2. التعبئة packing

Random العشوائية سهلة التركيب ، ولديها قدرة قوية على التكيف ، ومناسبة للسيناريوهات ذات قدرة المعالجة الكبيرة أو خصائص المواد المعقدة. مقاومة منخفضة ، ومعدل تدفق مرتفع ، وكفاءة نقل كتلة أفضل من التعبئة التقليدية مثل حلقات راشيغ. سيناريوهات

Applicable: في فصل إيثيل بنزين ، إذا كان معدل تدفق المواد كبيرًا ، تكون مرونة التشغيل عالية (مثل عندما يتقلب الحمل) ، أو تحتوي على كمية صغيرة من الشوائب غير المعرضة لانسداد التعبئة ، يمكن اختيار حلقات الخطوة. يمكن اختيار حلقات التآكل. منخفض (يمكن أن يتحمل البولي بروبلين درجات حرارة أقل من حوالي 100 درجة مئوية) ، يمكن استخدام حلقات Pall البلاستيكية لتقليل مخاطر تآكل المعدات. جزء الفراغ ومقاومة أعلى. سيناريوهات

Applicable: تستخدم فقط في ظروف خاصة حيث تحتوي مادة إيثيل بنزين على تآكل قوي (مثل احتوائها على أحماض غير عضوية) ودرجة حرارة عالية ، ويجب اختيارها بعناية بناءً على متطلبات كفاءة نقل الكتلة
