Developing state-of-the-art and separating principle of deoiling hydrocyclones are introduced. By theoretical analysis, the ways to enhance hydrocyclone’s separation efficiency are described. One way is to inject air into the hydrocyclones so as to combine with oil to form oil-gas compound body, and then increase de-oiling efficiency. By means of injecting air into large cone segment, or fine cone segment of the hydrocyclone, experiments were carried out. It is found that the best injecting part is fine cone segment. Further experimental studies were continued for confirming detail part in fine cone segment, which includes one-third segment and two-thirds segment for the sake of research. Results show that the best air-injecting part is the first one-third segment of fine cone segment. This conclusion would be useful for understanding of air-injected de-oiling hydrocyclone’s separating process, and for its design and applications.

This paper presents a numerical simulation and experimental study on a solid-liquid hydrocyclone. In the simulation, the standard k-ε turbulence model and the zero-equation model are employed to compute the flow field of the two phases in the hydrocyclone under different conditions, such as viscosity of the liquid, particle size and flow rate. In the experiment, a hydrocyclone is manufactured and measured for the separation efficiency and pressure drop in the test system. The simulation result of hydrocyclone performance matches well with the experimental data.

Helicopters operating in a desert region are often subjected to the environmental effects of sand ingestion that can erode gas turbine engines and block the cooling passages. Traditional method of removing sand particles include barrier filters that employed vortex tube and impact filter designs, and inertial particle separator (IPS). Barrier filters are normally quite heavy and require constant servicing or replacement. IPS relies on contoured surfaces to direct particulates to a scavenge area through the actions of the viscous forces and bounce characteristics of the sand particles. The geometrical design of an IPS plays an important role in determining the sand separation efficiency. This paper presents a numerical study of the RTM322 IPS, which includes the effects of changing the hub, splitter and scavenge duct geometries on the sand separation efficiency. The flow field calculation in the IPS was performed with the commercial CFD software package called TASCflow. The particle trajectories were computed using an in-house developed trajectory code, which was based on the lagrangian method. The effects of flow turbulence on the trajectory were simulated using the eddy lifetime concept. Several design geometrical modifications were investigated such as the shape of the hub and splitter and their relative locations. Particle trajectories and separation efficiency were performed for a range of sand particle sizes, inlet mass flow rates and scavenge ratios.

Hydrocyclones are separators that are widely used in industry that belong to an important group of equipments designed to solid-liquid or liquid-liquid separation. The employment of hydrocyclones is generally restricted to an equipment need with a high classifying power (based on the size of particles collected in the underflow) or with a high concentrating capacity. The separation occurs by density difference or particle size distribution of the dispersed phase. In order to maximize the separation efficiency of these devices, the aim of this work was to study experimentally the consequences of an unusual feed in the behavior of a hydrocyclone. Therefore, tests were carried out with aqueous suspensions of phosphate rock at a fixed level of pressure drop equal to 1.47 bar, using the optimized geometry hydrocyclone H11. The influence of the so called rotating feed inlet for the H11 was evaluated in clockwise and anticlockwise. Experimental studies have suggested that the rotation of the fluid in the feed inlet of hydrocyclone did not change significantly the underflow-to-throughput ratio (RL), although it has caused changes in the energy cost and in the performance of the separator.

An experiment setup was built to test the droplet separation performance of demister. Different experiments were conducted using various Polytetrafluoroethene (PTFE) meshes. Results show that the separation efficiency of demister is dependent on screen thickness, mesh count. Pressure drop increases with the increase of steam flow rate and screen thickness.

Experimental study of the separation efficiency of oil-gas cyclone separator for oil-injection compressor system was conducted with the aim of understanding the separation process and identifying the main parameters affecting the separation efficiency. Malvern Particle Size analyzer was applied to analyze the separators’ performance. By simultaneously measuring the oil droplet size distribution and oil concentration upstream and downstream of the separators, the separation performance was assessed. The results of the study contribute to an optimized cyclone separator design.
