Separator siklon silinder vertikal (Gas Liquid Cylindrical Cyclones) merupakan alat pemisahan aliran multifase yang umum dipergunakan dalam industri perminyakan. Penelitian ini bertujuan untuk mengevaluasi unjuk kerja dan perilaku hidrodinamika fluida separator GLCC metering loop pada pemisahan aliran campuran udara dan air. Eksperimen dilakukan dengan membuat separator skala uji laboratorium menggunakan pipa acrylic plexyglass diameter 6,25 cm, tinggi 140 cm dengan sistem inlet tangensial pada sudut inklinasi 30o, serta dilengkapi 5 variasi posisi saluran keluaran. Percobaan dilakukan dengan memvariasikan debit udara dan efek posisi saluran keluaran (recombination point). Beberapa aspek penting seperti kecepatan superficial gas (Vsg), kecepatan superficial cairan (Vsl), level cairan kesetimbangan (Leq), liquid carry over (LCO) dan gas carry under (GCU) menjadi perhatian selama percobaan. Hasil penelitian menunjukkan bahwa empat regim aliran yaitu aliran gelembung (bubble flow), aliran gelembung paket (packed bubble flow), aliran kantung gas atau sumbat cair (slug flow) dan aliran acak (churn flow) dipengaruhi oleh konfigurasi rasio aliran gas-cairan dan posisi rekombinasinya. Rasio kecepatan superfisial antara udara dan cairan memainkan peran penting terhadap terbentuknya regim aliran dan ketinggian level cairan kesetimbangan.

“…The petroleum industry also employs gas-liquid cylindrical separators and study of these separators is ongoing. Reyes-Gutierrez et al 7) utilized the CFX4.3 software package from Ansys to analyze the free surface and tangential velocity inside a typical gas-liquid cylindrical cyclone separator as patented by the University of Tulsa in 1994. Both a single phase and two-phase simulation were used to compute the azimuthal velocity profile.…”

Fuel cells have been used as a power source in the space shuttle for decades and are expected to be used in future higher power, larger systems. A new, passive gas/liquid phase separator for use in such large fuel cell space applications has been invented. It is a vortex separator designed to accommodate gas driven two phase flows. The work presented here is a first of a kind study of this newly invented separator examining the minimum inlet gas flow rate necessary for a stable vortex inside the separator as a function of separator size. A dimensional scaling analysis was done to predict this minimum inlet gas flow rate. Experiments were performed on the ground and in conjunction with the NASA microgravity simulating aircraft to validate modeling. The results of the experiments and scaling analysis are compared.

“…This oil drop diameter is in good agreement with experimental data, shown in [11], obtained at similar mixture velocities. The RNG κ-ε turbulence model was used since it has shown satisfactory results when comparing the speed of rotation of the mixture with experimental data [10]. The simulation runs were carried out in a Pentium IV 3.2 GHz, 1 GB RAM computer taking approximately 5 hours for each run.…”

A Liquid-Liquid Cylindrical Cyclone separator (LLCC) is a device used in the petroleum industry to separate the oil-water mixture obtained from the well. The use of this device has not been widespread due to the lack of tools for predicting its separation capability. This paper presents a numerical and experimental study of the fluid dynamic performance of this type of cylindrical cyclone separators. The use of numerical simulations would reduce the time and cost necessary to obtain information for predicting the behavior of the equipment. The objective of this study is to determine if CFD (Computational Fluid Dynamics) techniques are able to reproduce the behavior of a LLCC separator. The CFD software examined was ANSYS-CFX 5.6 TM and numerical simulations were carried out using the dispersed model with oil as the dispersed phase. The oil and water mixture entering the separator is divided due to centrifugal and buoyancy forces in an upper (oil rich) exit and a bottom (water rich) exit. The separation capability is determined as the maximum amount of water removed from the mixture with the minimum amount of oil content in the water rich exit. The experiments were conducted in a transparent LLCC separator that allows the visualization of the mixture and the measurement of the oil content. Experiments were conducted for three variables: mixture velocity and water content at the entrance, and the split ratio. The split ratio is defined as the bottom exit flow rate divided by the water flow rate at the entrance. The results showed that CFD tools are able to reproduce the oil content obtained from the experiments for all analyzed conditions. Additionally, the mixture distribution images from numerical and experimental data showed good agreement. This study confirms the capacity of CFD tools for the multiphase flow analysis of LLCC separators.
