AQUIFER HYDRAULIC CHARACTERISTICS AND VULNERABILITY ESTIMATION FROM VERTICAL ELECTRICAL SOUNDING: A CASE STUDY OF ORU AND ENVIRONS,SOUTH EASTERN NIGERIA

Abstract:

Aquifer hydraulic characteristics and vulnerability assessment are essential for sustainable groundwater management, particularly in regions facing increasing water demands and environmental stresses. This study focuses on the estimation of aquifer hydraulic parameters and vulnerability using Vertical Electrical Sounding (VES) data in the Oru and its environs, located in South Eastern Nigeria.

Vertical Electrical Sounding is a geophysical technique widely used for subsurface investigations, particularly in hydrogeological studies. In this research, VES data were collected at strategic locations within the study area. The data were interpreted using the Schlumberger array to derive the aquifer parameters, including the hydraulic conductivity (K) and transmissivity (T).

The results reveal spatial variations in aquifer hydraulic characteristics across the study area. The estimated values of hydraulic conductivity and transmissivity provide valuable insights into the potential groundwater yield and flow characteristics of the aquifer system in Oru and its environs. Additionally, the vulnerability of the aquifer to contamination was assessed using the DRASTIC method, which considers various factors such as Depth to Water Table (D), Net Recharge (R), Aquifer Media (A), Soil Media (S), Topography (T), Impact of Vadose Zone (I), and Hydraulic Conductivity (C).

The vulnerability assessment indicates areas of varying degrees of vulnerability to contamination, highlighting zones where groundwater resources are at higher risk. These findings are crucial for groundwater resource management, land-use planning, and the development of appropriate mitigation measures to protect the aquifer system.

This study contributes to the existing knowledge by providing a case study of aquifer hydraulic characteristics and vulnerability assessment using VES data in South Eastern Nigeria. The results offer valuable insights for policymakers, water resource managers, and stakeholders in sustainable groundwater management practices in the region.

CHAPTER ONE

INTRODUCTION

Abstract:

The escalating demand for sustainable energy sources has fueled the exploration of innovative technologies for renewable energy production. This study focuses on the production of biogas through the anaerobic digestion of cow dung and cereal waste, employing sodium and calcium alginates as immobilization agents. Cow dung, a widely available organic waste, and cereal waste are chosen as feedstocks for their abundance and potential to contribute to the circular economy. Sodium and calcium alginates are utilized to immobilize anaerobic bacteria, aiming to enhance biogas production efficiency. The research investigates the optimal conditions for biogas production, assessing the impact of substrate composition, immobilization agent concentration, and process parameters. Laboratory-scale experiments are conducted to analyze biogas yield, composition, and the economic and environmental feasibility of the proposed system. The outcomes of this study contribute to the knowledge base on sustainable waste-to-energy technologies, providing insights into the viability of utilizing locally available waste materials for efficient biogas production.

1.1 Background of the Study

The global quest for sustainable and renewable energy sources has intensified in response to environmental concerns, energy security, and the need to reduce dependence on non-renewable fossil fuels.

GAS DEHYDRATION USING TRIETHYLENE GLYCOL (A CASE STUDY OF SHELL, UGHELI)

CHAPTER ONE

INTRODUCTION

Background of the study

Natural gas is a combustible gaseous mixture of gaseous hydrocarbons, very light liquid hydrocarbons, free water, water vapour and other undesirable non – hydrocarbon gaseous and solid compounds found in conventional natural gas reservoirs as non-associated gas (NAG), as associated gas (AG) or as gas condensates.

Associated gas or gas-wellhead-gas is found in contact with oil in the reservoir and is produced with the oil and separated at the casing head or wellhead whereas non- associated gas contains little or no natural gas liquids (oil) at reservoir condition and it is termed dry gas or lean gas if the fluid at the surface still remains gas. However if the surface pressure cause some liquid hydrocarbon to evolve, it is called a wet gas or rich. Condensate occurs not as liquid or gas but as a very dense and high pressure fluid due to its high pressure and high temperature reservoir condition.

Natural gas may also occur in tight sands, tight shales, methane gas occluded in coal, as gas hydrates in geo-pressurized acquifer and as deep gas. These gases are more technologically difficult or more expensive to produce than conventional gas and are termed non- conventional natural gas.

Hydrocarbon majorly contained in the natural gas mixtures are methane and ethane which exist as gaseous components, propane and butane existing as volatile fluid, pentane, small amount of hexanes and heavier components existing as liquid components. Typical non- hydrocarbon which may exist in the gas stream are solid particles, water vapour or free water, mercury, formaldehyde, benzene, toluene, ethyl benzene and xylene (collectively referred to as BTEX), undesirable gases such as carbon oxides, sulfur gases and nitrogen oxides (collectively called acid gases), oxygen, helium and naturally occurring radioactive materials such as radon.

Ethane C2H6 3-8

Propane C3H8 1-2

Butane C4H10 <1

Pentane C5H12 <1

Carbon dioxide CO2 1-2

Hydrogen sulfide H2O <1

Nitrogen N2 1-5

Helium He <0.5

Mercury Hg Traces

Benzene C6H6 Traces

Toulene C7H8 Traces

Natural gas is a fossil fuel composed almost entirely of methane. The composition of natural gas varies depending on the field, formation, or reservoir from which it is extracted. Natural gas which contains acid gases above customer’s specification is termed sour gas while Natural gas containing acid gas below customer’s specification or no acid gas is termed sweet gas.

Natural gas is a fossil fuel formed by either the biogenic or thermogenic degradation of organic matter which has been accumulated over time within the earth’s crust. Biogenic mechanism involves shallow depth and low temperature decomposition of sedimentary organic matter by anaerobic bacterials whereas thermogenic mechanism involves deeper depth and high temperature thermal cracking of sedimentary matter or oil into gas. Natural gas being a fossil fuel is today, one of the most important fuels in our lives as it is the source of energy for household, industrial and commercial use, as well as to generate electricity.

Natural, associated or tail gas usually contains water, in liquid and/or vapour form, at source and/or as a result of sweetening with an acqueous solution. Operating experience and thorough engineering have proved that it is necessary to reduce and control the water content of gas to ensure safe processing and transmission. This is accomplished by the process of dehydration.

1.1 NATURAL GAS DEHYDRATION PROCESSES

Natural gas dehydration is the removal of water or water vapour from the natural gas stream. Free water in natural gas gives rise to difficulties in production, handling and transmission of natural gas. It is therefore necessary that water be removed from the gas stream as soon as possible.

There are several methods of dehydrating natural gas but the most common of these methods are:

(i)Refrigeration

(ii)Adsorption

(iii)Absorption

1.11 REFRIGERATION

This method employs cooling the natural gas to condense the water molecules to the liquid phase with the subsequent injection of inhibitor to prevent hydrate formation.

1.12 ADSORPTION

This is the removal of water from the gas stream by solid materials called desiccants which take in and hold water molecules within themselves by adhesive forces. Several types of solid desiccant used are silica gel, silica-based beads, activated alumina, activated bauxite, membranes and molecular sieves.

1.13 ABSORBTION

This is the process whereby water or water vapour is removed or absorbed from the gas stream by intimate contact with a liquid desiccant. Of all the liquid desiccants, the glycols have proved to be the most effective in current use as they approximate the properties that meet commercial application criteria. The glycol with absorbed water is regenerated and re-circulated into dehydration cycle for further water removal.

Chemically, glycol is an aliphatic organic compound belonging to the group of chemicals referred to as dihydric alcohols (diols). Physically, glycols are similar to water in that, they are colourless, clear and odourless liquids. They however possess greater specific gravity and viscosity than water at all temperatures and are soluble in water.

The four types of glycols that have been successfully used to dehydrate natural gas are;

Monoethylene glycol (MEG)

Diethylene glycol (DEG)

Triethylene glycol (TEG)

Tetraethylene glycol (T4EG)

Triethylene glycol has gained nearly universal acceptance as the most cost effective of the glycols due to superior dew point depression, operating cost and operation reliability.

Among the different gas dehydration processes, absorption dehydration is more economically attractive hence has become the most popular method.

1.2 STATEMENT OF PROBLEM

Gas dehydration is a common process in gas treatment plant because water in the presence of acid compounds in natural gas can cause corrosion; water also combines with hydrocarbons to form hydrates which can block valves and pipelines. During an absorption dehydration process of natural gas using tri-ethylene glycol, an appreciable quantity of glycol could be lost and a significant amount of volatile organic compounds emitted during regeneration which may be as a result of operational faults or inadequate plant design. Excessive loss of glycol may lower the efficiency of the dehydration process consequently increasing the cost of dehydrating the gas. VOCs emissions may raise concern from environmental regulatory bodies.

1.3 AIMS AND OBJECTIVES

This project work is aimed at

1. Analyzing the basic process of gas dehydration using Triethylene Glycol.

2 Studying glycol regeneration process as well as examining the causes of associated glycol loss during the regeneration process with possible solutions proffered.

3. Examining the causes of Volatile organic compounds emission with possible solutions proffered.

1.4 SCOPE AND LIMITATIONS

1. Use of TEG for the dehydration of natural gas.

2. Investigating the Parameters affecting glycol regeneration.

3. Investigating the parameters influencing BTEX emissions.

1.5 METHODOLOGY

The various units of operation of the plant will be studied. Sensitivity analysis of process parameters such as temperature of inlet gas and inlet TEG, in relation to the degree of dehydration and BTEX emissions will be carried out. Previous works on the subject will also be examined.

1.6 CASE STUDY

The Shell Petroleum Development Company (SPDC) gas compression and dehydration plant in Ughelli will be used as case study to achieve the major objectives of this research work.
