چکیده
The present study employed a population balance model to predict particle size distributionchanges over time in a dead light crude oil. The developed model was validated using a set of particlesize distribution data at different temperatures and the modeling results clarified the effect oftemperature on the kinetic parameters. Since the system was under static conditions, only the Brownianaggregation kernel of Smoluchowski was incorporated into the model and collision efficiency wasadjusted for different temperatures and fractal dimensions. A sensitivity analysis was performed fordifferent fractal dimensions reported in the literature. The results revealed a rising trend for collisionefficiency with temperature. Additionally, the adjusted values for collision efficiency were stronglydependent on fractal dimension while a reverse trend was found between Collision efficiency and fractaldimension. The more the temperature was, the more the results were affected by changing the insertedfractal dimension. The modeling results created an average root-mean-square-error (RMSE) of ۹.۶%.Despite the collision efficiency dependence on the fractal dimension, the predicted particle sizes wereless sensitive to the applied value of the fractal dimension.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
