A wellhead multistage bundle gas–liquid separator combining a cylindrical cyclone (GLCC) with multi-tube components is expected to improve the separation performance. However, there no unified understanding of factors influencing performance separator. The continuous improvement and applications are restricted. This paper evaluated using numerical simulation method. results indicate that flow f...

RELEVANCE. Cyclone separators are used to separate solid dust particles from the air entering turbine. The key factors in their selection pressure drop and efficiency. Research aimed at improving these indicators while preserving other advantages of cyclones, as well development new gas cleaning devices that not inferior them, relevant. THE PURPOSE. Comparison technical characteristics a multi-...

cement powder size classification efficiency significantly affects quality of final product and extent of energy consumption in clinker grinding circuits. static and dynamic or high efficiency air separators are being used widely in closed circuit with multi-compartment tube ball mills, high pressure grinding rolls (hpgr) and more recently vertical roller mills (vrm) units in cement plants to c...

The flow field, pressure drop, and separation efficiency of an industrial cyclone separator were computationally investigated using the Reynolds stress model simulations. effects flapper valve on static cut size, slope grade curve revealed. For that, was simulated in three operation regimes, when is open, closed, without valve. results showed that a increases size by 3.4 % it position “closed” ...

The separation of bubbles in a gas–liquid cyclone is complicated. A combination numerical simulation and visual experimentation was considered apt to reveal the microscopic mechanisms bubble flow. First all, cyclones with different structures were numerically simulated. calculation results show that larger diameter exhaust port, better flow effect. When port 24 mm, gas discharge efficiency 8% h...

Currently, computational fluid dynamics has become the primary method for analyzing flow state inside machine. Herein, Ansys Fluent software is used to design a more effective oil-field device, namely, gas–liquid cylindrical cyclone (GLCC)-horizontal combined separator. The characteristics of mixed flow, turbulence intensity, and phase volume fraction distribution are analyzed, factors affectin...
