Modelling of a microfluid ultrasonic particle separator
Particles within an ultrasonic standing wave experience an acoustic force causing the particles tomove to certain positions within the acoustic field. This phenomenon can be used to manipulate particles and so provides a means to separate, concentrate or trap particles, cells or spores. The work …

Catalytic membrane reactor-separator for environmental applications.
Flow-through catalytic membrane reactors offer the potential for improved conversions at reduced operating temperature due to product separation and catalyst activity. An experimental work dealing with a forced flow-through membrane reactor is the subject of this thesis. The focus is on the …

Aerodynamic Interactions in Vortex Tube Separator Arrays
… air-particle separation is the vortex tube separator (VTS), which uses centrifugal forces in a vortical flow to radially filter foreign particles from a duct with an annular exit. Dozens or hundreds of these devices are linked together on a shared manifold known as a VTS array. There is a …

A Separator-Based Framework for Graph Matching Problems
… we assume that the graph has a small balanced separator, meaning it is possible to split the graph into two roughly equal-size components by removing a relatively small portion of the graph. Several well-studied classes of graphs have separator-like properties, including planar graphs, …

Monitoring separation process in separator tanks by ultrasound technique
The focus of this project is to monitor the level of interfaces inside the separation tank during the refining of crude oil by using ultrasound technology. The primary objective is to develop a robust method to measure liquid separation levels in both horizontal and vertical tanks by analyzing the …

Bounds on k-Regular Ramanujan Graphs and Separator Theorems
… a Ramanujan graph. Families of graphs that have separator theorems fail to be Ramanujan if the vertex set gets sufficiently large. Using separator theorems to get an estimate on the expanding constant of graphs, we get bounds 011 the number of vertices for such fc-regular graphs in order for them …

Downhole Gas Separator Performance in Sucker Rod Pumping System
… entering into the pump is to use downhole gas separators. The main purpose of these devices is to facilitate agglomeration of gas bubbles so that they migrate upwards and can be released through the casing annulus. Design and selection of downhole gas separators is usually done using …

Design And Testing Of A Triboelectrostatic Separator For Cleaning Coal
Numerous advanced coal-cleaning processes have been developed in recent years that are capable of substantially reducing both ash and sulfur-forming minerals from coal. However most of the processes involve fine grinding and use water as a medium; therefore, the clean coal products must be …

Mechanical behavior of shell casing and separator of lithium-ion battery
… battery cells consist of cathode, anode, separator and shell casing or aluminum plastic cover. Among them, the shell casing provides substantial strength and fracture resistance under mechanical loading, and the failure of the separator determines onset of internal short circuit of the …

Evaluation of Hydraulic Separator Applications in the Coal and Mineral Industries
… industry has commonly utilized hydraulic separators throughout history for classification and gravity concentration of various minerals. More commonly referred to as hindered-bed or fluidized-bed separators, these units make use of differential particle settling rates to segregate …

In-Plant Testing of the Hydrofloat Separator for Coarse Phospahte Recovery
… a result, the HydroFloat also acts as a density separator that is capable of treating much coarser particles as compared to traditional flotation processes. In addition, the high solids content of the teeter bed promotes bubble-particle attachment and reduces the cell volume required to achieve a …

The characterisation of the hydrodynamic vortex separator using residence time distribution analysis.
The hydrodynamic vortex separator (HDVS) is currently employed at wastewater treatment works and in the sewerage system as a combined sewer overflow (CSO) for the separation of solids from an incoming waste stream. This project presents the first stage in developing and aiding the existing design …

Flow and separation of the oil from compressor discharge to external separator
… on the heat transfer and total efficiency. Oil separator is an important component to reduce the amount of oil circulating in the system and to keep the oil in the compressor. Though commonly applied in the industry, oil separator still needs a systematic design guideline. The understanding of …
