Design of Effective Solid Waste Management System: A Case Study of Ifite-Awka zone, Anambra State

Focuses on the maximum volume of waste generated in a particular month in a particular area and uses a heuristic model for it's analysis.Research ProblemA proper, efficient, reliable and hygienic waste handling and disposal technique tells more of our maintenance culture but the capacity and ability to efficiently manage the  waste  becomes inadequate.   The need   for this   study a rose because effective waste management is a tool for sustainable deve...

A Comparative Study of Gas Condensate Stabilization Techniques using Aspen HYSYS

AbstractIn this report, we perform a comparison of two gas condensate stabilization techniques: fractional distillation and multi-flash vaporization. Our prime objective is to compare relevant parameters .e.g. Reid vapor pressure (RVP) and associated costs in order to determine the more effective method for the stabilization of our gas condensate feed. The Aspen Plus software application suite was extensively used for the process design and simulation as well as the economic analysis for this...

Application of Reveal for polymer flooding modelling

ABSTRACTThe maximum recoverable oil in place from the reservoir is a major challenge when it comes to EOR which is an essential part of every oil production project. In some cases, the natural drive mechanism is a relatively inefficient process and results in a low overall oil recovery. The lack of sufficient natural drive in such reservoirs has led to the practice of supplementing the natural reservoir energy by introducing some form of artificial drive, the most basic method being the injec...

DETERMINATION OF REMOVAL EFFICIENCY OF METHYLENE BLUE FROM AQUEOUS SOLUTION USING CHEMICALLY ACTIVATED CARBON PRODUCED FROM MANGO SHELL

ABSTRACTThe presence of methylene blue (MB) in wastewater is a major concern in the environment due to its low biodegrability and harmful effect on man. The treatment of effluent containing such dye is important where adsorption on activated carbon (AC) produced from agricultural waste is of great choice. Optimization of the removal efficiency of MB from aqueous solution onto AC prepared from mango shell was investigated. The AC was prepared from mango shell, activated with BaCl2 at I.R (0.03...

OPTIMIZATION OF CONDITIONS FOR THE PRODUCTION OF ACTIVATED CARBON FROM MANGO KERNEL SHELL USING BARIUM CHLORIDE AS THE ACTIVATING AGENT

ABSTRACTThis study was conducted to remove mango shell waste which is one of the seasonal environmental nuisance items and recycle it as a precursor for the production of activated carbon. Discarded mango shells were sourced from local vicinity, and they were washed thoroughly to remove dirt, sundried and reduced to smaller sizes. Two-Level Factorial Design under Factorial Methodology of Design Expect (10.0.1) software was employed to optimize interaction of impregnation ratio (0.033 - 0.167 ...

The Role of Satellite Network in future 5G wireless networks

ABSTRACTThe document outlines an investigation done in order to study Fifth Generation (5G) systems and to identify a role that satellite systems will play in contribution to the many advanced and diverse demands on existing telecommunication networks. This next generation network is a build-up and phenomenal improvement in wireless communication done by the “5GPP” on the already existing mobile generations. The evolution has seen us move from first generation which employed...

Commutation failures in HVDC Schemes

Commutation failures are very frequent dynamic events in high voltage dc (HVDC) transmission systems. Commutation failure is mostly observed at the inverter side of HVDC links, where large firing angles are used. The minimum value of the extinction angle required for the proper operation of a valve is specified by the valve manufacturer; however, at the inverter side of HVDC systems the extinction angle is regulated to a value higher than the valve specifications to allow control adjust...

The ability of AC/DC converters to generate and consume reactive power

ABSTRACT The conversion of an input AC power at a given frequency and voltage to an output power at different frequency and voltage can be obtained with static circuits called power converters, containing controllable power electronic devices. Various power converters have been developed to fulfill the requirements of the wind power generation. The most common option for the generators used in wind power generation is “asynchronous”, because support for speed variations is provi...

Voltage Collapse in Power System

The power system is a highly nonlinear system that operates in a constantly changing environment; loads, generator outputs, voltage controllers, transmission lines, topology, and key operating parameters change continually. The behavior and output of the generators can be affected in a transient conditions. This transient condition can change the excitation and dynamics of the rotor which in turn produces undesirable oscillations of the system frequency and voltage magnitude. When subje...

Variable Speed Drives for AC machines

ABSTRACT Industrial drive applications are generally classified into constant-speed and variable-speed drives. Traditionally, AC machines have been used in constant-speed applications and DC machines were preferred for variable-speed. Induction machine with drive systems are widely used in applications such as pumps, paper and textile mills, elevators, electric vehicle, subway transportation, home appliance and wind generation. The three-phase squirrel cage induction motor is the mos...

Performance Assessment of the Firefighting Personal Protective Tunic

ABSTRACTThis project centers on addressing the issue of the lack of research and development in Nigeria, in this case, looking into the firefighting and emergency sector. In this industry, the safety of the firefighters is of paramount importance as it is only then that they can fully carry out their duties and tasks. Of all the products that make up a complete assemble of the firefighters’ PPE, it is their personal protective tunic that was used for this project as it is the basic and most...

Optimal Placement of Capacitors in a Distribution System

Abstract  Optimal capacitor placement is concerned with the optimal location of capacitors in a distribution system such that energy losses are reduced to a minimal value and the voltage profile and power factor of the system is improved. The reactive power can be controlled in order to improve the voltage profile and minimize the system loss. Generally, some load bus voltage might violate their upper or lower limits during system operation due to disturbances and/or system configuration ch...

DESIGN CONSTRUCTION AND IMPLEMENTATION OF A TOUCH SENSITIVE SWITCH

ABSTRACT A switch is an imperative constituent of any electronic or electrical circuit. It can either be mechanical, electro-mechanical or electronic. Mechanical and electro mechanical switches are prone to wear and tear with time. The introduction of semiconductors has led to the invention of electronic switches that are more efficient, fast and durable. Further development of electronic switches led to the production of touch-sensitive switches. This project is based on the design and const...
