[ 1 ] - Selecting Optimal Acid Gas Enrichment Configuration For Khangiran Natural Gas Refinery
 Performance and capacity of sulfur recovery unit (SRU) are greatly affected by the H2S:CO2 ratio of the acid gas stream. The acid gases in Iran contain around 35 mol% H2S and 60 mol% CO2. This low concentration of H2S calls for more complex sulfur plant, larger equipments, and higher costs. Acid gas enrichment processes (AGE) is run to upgrade low quality acid gas collected from gas treating...
[ 2 ] - Investigating the Effects of Inlet Conditions and Nozzle Geometry on the Performance of Supersonic Separator Used for Natural Gas Dehumidification
Supersonic separators have found extensive applications in dehumidification of natural gases since 2003. Unlike previous studies, which have investigated the inlet conditions and nozzle geometry of supersonic separators for pure fluids, the present study employed a combination of momentum, heat, and mass transfer equations along with Virial equation of state (EOS) to inspect the effect of inlet...
[ 3 ] - Modeling and Simulation of Heat Transfer Phenomenon in Steel Belt Conveyer Sulfur Granulating Process
Complex heat transfer phenomena (including unsteady state conduction, convection and solidification processes) occur in steel belt conveyer sulfur granulating method. Numerical simulation of this technique is performed via a comprehensive and multifaceted one dimensional model. Since the air situated between the adjacent sulfur pastilles is essentially stagnant, therefore, the surface tempe...
[ 4 ] - A Theoretical Mass Transfer Approach for Prediction of Droplets Growth Inside Supersonic Laval Nozzle
Proper estimation of droplet growth rate plays a crucial role on appropriate prediction of supersonic separators performance for separation of fine droplets from a gas stream. Up to now, all available researches employ empirical or semi-empirical correlations to define the relationship between droplet growth rate (dr/dt) and other operating variables such as temperatures (T and TL), Pressure (P...
[ 5 ] - بررسی عملکرد شبکه عصبی مصنوعی MLP، RBF و ORN در یک کانال افقی همراه با انتقال جرم و انتقال حرارت همزمان
در بیش تر فرایندهای مهندسی شیمی پدیده های انتقال جرم و انتقال گرما مشخصه های جدایی‌ناپذیر فرایندها می باشند. در این پژوهش با استفاده از یک دستگاه آزمایشگاهی، به بررسی تجربی همزمان این دو پدیده در فرایندهای مهندسی شیمی و تأثیراتی که بر روی هم و بر روی فرایندها می توانند داشته باشند، پرداخته شده است. در این دستگاه وجود پدیده های چگالش و تبخیر، باعث انتقال جرم شده و سرانجام بر ضریب انتق...
