بررسی تجربی اثر توزیع کننده گاز و ارتفاع مایع بر ماندگی گاز در راکتورهای حبابی

چکیده

ماندگی گاز یکی از عوامل مهم برای پیشگویی رفتار هیدرودینامیکی در راکتورهای حبابی است. از عوامل مؤثر بر ماندگی گاز، نوع توزیع کننده گاز و ارتفاع ستون مایع است.
 در این تحقیق از یک ستون استوانه‌ای به قطر cm 15 و مجهز به دو نوع توزیع کننده گاز، استفاده و اثر توزیع کننده گاز و ارتفاع ستون مایع در سرعت‌های متفاوت گاز بررسی شدند. نتایج آزمایش‌ها نشان می‌دهد که، افزایش ارتفاع ستون مایع و کاهش قطر منافذ توزیع کننده گاز، باعث افزایش ماندگی کلی گاز در سیستم می‌شود.

Experimental Study of Sparger Type and Liquid Height on Gas Hold-up in Bubble Column Reactor

چکیده [English]

Gas hold up in bubble column reactors is one of the important parameter to predict hydrodynamic behavior in bubble column reactors.
Since sparger type and liquid height have important effect on total gas hold up, In this study a cylindrical bubble column with 15 cm diameter which has equipped with 2 type sparger is used to study the effect of sparger type and liquid height at different superficial gas velocity on total gas hold up. The results show that increasing liquid height and decreasing sparger hole diameter increase the gas hold up.
