Abstract

ترمي هذه الدراسة إلى توصيف الظروف التشغيلية لمرشح الفحم الفعال، وذلك بالاعتماد على منحنيات الاختراق. تم تطبيق فرضية انتقال الكتلة (MTZ) بهدف الحصول على تصميم تشغيلي للامتزاز على السرير الثابت والتي تساعد على تحديد متغيرات التشغيل على هذا السرير. اختبر الفحم التجاري المتحدر من مصدر نباتي (0.2-6mm) تم الحصول عليه من شركة (POCH) البولندية. حيث درست منحنيات الاختراق عند أربعة حجوم حبيبية مختلفة (A, B, C, D)، مجالات أقطارها هي على التوالي  (1000-2000), (500-1000), (250-500), (125-250)mm، وذلك عند ثلاثة تراكيز ابتدائية للفينول 20, 40, 60ppm)). درست المتغيرات التشغيلية لعمود الامتزاز بحساب السعة الجزئية لمنطقة انتقال الكتلة F).) وارتفاع منطقة انتقال الكتلة Hz كذلك عدد مكافئات الانتقال Nz والكمية الفعلية للفينول التي أزيلت على سرير ثابت من الكربون الفعال عند لحظة الاختراق ABP. وتبين من خلال النتائج أن الحجوم الحبيبية (C, D) هي الأكثر فاعلية لاستخدامها في المرشح من الحجوم (A, B).

The objective of the present work is to determine the operating conditions of an activated carbon filter, based on the characteristics of breakthrough curves. This aims to properly design and operate fixed-bed adsorption processes. We apply the concept of the mass transfer zone (MTZ) that helps to obtain the evolutions of the operating parameters of the fixed-bed. Charcoal activated (0.2-0.6 mm) purchased from POCH SA (Poland) was studied.

 

Breakthrough curves have been studied on four different particle sizes of the adsorbent (A, B, C, D) with diameter ranges (1000-2000), (500-1000), (250-500), (125-250)mm respectively, and three initial concentrations of phenol (20, 40, 60ppm). The experimental data were analyzed by calculating fractional capacity (F), the height of (MTZ) (HZ), the number of unit transfer equivalent (NZ). The amount of phenol eliminated by the bed of activated carbon at the breakthrough (ABP). The results of the study show that granular sizes (C, D) were more effective than (A, B).
