An innovative axial hydrocyclone separator was designed in which a guide vane installed to replace conventional tangential inlet, potentially aggravating inlet turbulence. The characteristics of velocity distribution, concentration and pressure distribution inside the were obtained through numerical simulation turbulent flow oil water. results showed that field presented good symmetry, eliminat...

Hydrocyclones have been used as an operational tool to separate liquids from solids in different industries for more than 50 years. Considering the importance of this issue, many experimental and numerical attempts have been made to estimate the performance of this tool regarding the resulting pressure drop and the separation efficiency (particles separation limit diameter...

In Oil and gas productions, the severe slug is an undesired flow regime due to negative impact on production rate facility safety. This study examines riser-induced slugs’ influence a typical separation process, consisting of 3-phase gravity separator physically linked deoiling hydrocyclone. Four inflow scenarios are compared: Uncontrolled, open-loop, feasible, infeasible closed-loop anti-slug ...

Wastewater treatment of machine-building enterprises contaminated with oils, petroleum products and mechanical impurities is an urgent task. A promising direction in the field such wastewater use pressure hydrocyclones hydrocyclone installations. The article presents results research on oil-containing hydrocyclones, conducted experimental installation, which includes under test, a sedative tank...

Large-eddy simulations have been conducted for two-phase flow (water and air) in a hydrocyclone using Two-Fluid (Euler–Euler) Volume-of-Fluid (VOF) models. Subgrid stresses are modeled dynamic eddy–viscosity model, results compared to those the Smagorinsky model. The effects of grid resolutions on mean turbulence statistics thoroughly investigated. Five block-structured grids 0.72, 1.47, 2.4, 3...

Sand has significant side effects on oil production and offshore platform processing system. Mini-hydrocyclones is a very important component to desanding operation However, even slight modification the structural parameter of hydrocylone might result in influence its flow field separation efficiency. So, analysis characteristics efficiency mini-hydrocyclones can help optimize parameters. In th...
