چکیده

اخیراً نسل جدیدی از تفکیک‌گرها با عنوان تفکیک‌گرهای سیکلون استوانه‌ای گاز و مایع توانسته‌اند خود را به عنوان جایگزین مناسبی برای تفکیک‌گرهای معمول جاذبه محور معرفی کنند. در این پژوهش تلاش شده است تا تاثیر ایجاد تغییرات فیزیکی در اجزای مختلف این تفکیک‌گر بر روی عملکرد و دامنه آن مورد بررسی و تحقیق واقع شود. از این رو نتایج این تغییرات بر روی یک نمونه آزمایشگاهی تفکیک‌گر سیکلون استوانه‌ای گاز و مایع که سیال هوا را از آب جدا می‌کند، مشاهده و گزارش شده است. همچنین تاثیر این تغییرات بر روی نتایج مدل ریاضی ثابت شده برای این تفکیک‌گر بررسی شده است. این تغییرات فیزیکی شامل افزایش طول خروجی های گاز و مایع، کاهش ستون گازی، قطر نازل ورودی، قطر بدنه اصلی و خروجی‌های گاز و مایع است. نتایج این تحقیق نشان می‌دهند که کاهش در قطر نازل ورودی باعث بهبود عملکرد تفکیک فازها دستگاه شده است. این در حالی است که هرگونه کاهش قطر بدنه اصلی و قطر خروجی‌های گاز و مایع تفکیک‌گر جدایش فاز‌های سیال چندفازی را مشکل‌تر کرده است. همچنین تغییر در طول ستون گازی تفکیک‌گر تغییری در عملکرد دستگاه نشان نمی‌دهد. هرگونه افزایش در طول خروجی دستگاه باعث بیشتر شدن اثر اصطکاک و تضعیف عملکرد دستگاه می‌شود.

چکیده [English]

The Gas-Liquid Cylindrical Cyclone (GLCC) separators have proven themselves in laboratory and field, as a well alternative to the conventional gravity-based gas/liquid separator. This study presents investigation of the effect of changes in physical aspects on GLCC performance. These changes are including increases in outlet length and reduction in gas body column length, inlet, body column, liquid and gas outlet diameter. In addition, results show that reduction of inlet diameter enhances the GLCC performance but any reduction in diameter of body column and liquid outlet has negative effect on that. Also, changes in gas outlet diameter does not have any effects on the GLCC flowrates domain. Finally, any increase in length of outlets rises the friction force and diminishes the performance of separator.
