Case study - Agiba Gas Power Generation
Proserve has recently carried out a power generation project with Agiba Petroleum Company in the western desert of Egypt to utilize the waste free flare gas instead of the very expensive fossil diesel fuel to power the oil production wells ‘pumps. The project faced several technical challenges. The associated gas has a low methane number” less than 45”, which necessitated a ...

Fuel for thought: European energy market restructuring and the future of power generation gas use
The liberalisation of the West European electricity and gas markets, technological developments in power technology and environmental policies are expected to stimulate continued strong growth in power generation gas consumption. This paper examines the importance of three frequently disregarded considerations in the analysis of expanded gas use in power generation. These include: (a) better use ...

Fast solution technique for unit commitment by particle swarm optimisation and genetic algorithm
In solving the Unit Commitment (UC) problem, two types of decision variables need to be determined: the start/shut down status and the output of power generation. Efficiently calculating the optimal commitment (on/off) and Economic Dispatch (ED) generations of the units at a sequence of times in the scheduling period is known as a challenge issue. In this paper, the proposed integrated PSO/GA ...

Efficiency of a standard gas-turbine power generation cycle running on different fuels
This paper presents a study of second-law efficiency in a standard Brayton combined cycle power generation, using several paraffinic fuels ranging from methane to heptane. The main objective of the study was to identify a trend with the number of carbon atoms in the compound. In this way, a qualitative criterion can be built to evaluate the properties of poor-quality gas turbine fuels containing ...

Exergy analysis of a natural gas fired combined cycle power generation unit
Combined cycle power generation units are becoming popular due to their higher energy conversion efficiency and reduced pollutants and greenhouse gas emissions. In the present work, exergy analysis of a natural gas fired combined cycle power generation unit is performed to investigate the effect of gas turbine inlet temperature and pressure ratio on exergetic efficiency for the plant and exergy ...

Optimisation of micro gas turbine by exergy, economic and environmental (3E) analysis
This research proposes a new method for optimisation of a power generation system based on exergy fuel cost and external social cost of air pollution. A thermodynamic model is provided to estimate the outlet mass flow rates of CO2, CO, NO and NO2 for a gas turbine based on maximising the first and second law efficiencies and minimising the objective function. Results show that inclusion of the ...

Second law analysis of an irreversible Braysson cycle
This paper demonstrates the second-law analysis of an irreversible Braysson cycle. The overall second law efficiency for the process at variable operating conditions are being derived and plotted. In addition, for further pinpointing and thorough quantification of the losses, the component-wise second law efficiencies are also derived. It had been concluded that, the second law efficiency can be ...

Integrated GTL power-generation technology: the optimal solution to natural gas exploitation in Nigeria
Nigeria has an estimated 187 trillion cubic feet (Tcf) of proven gas reserves. Almost 50% of annual associated gas produced is flared or re-injected for enhanced recovery. Currently, the preferred option for exporting stranded gas is liquefied natural gas (LNG). However, the world LNG market is relatively small compared to middle distillates, and strongly driven by long-term and high risk ...

Exergy analysis of a combined fuel cell and Gas Turbine Power Plant with intercooling and reheating
This paper presents a comparative exergy study of the performance of various gas turbine power generation plants and a high temperature Solid Oxide Fuel Cell (SOFC). The overall system is analysed and its exergy efficiency and exergy destruction are obtained, as well as individual models of each component. The results for selected operating conditions are compared against past literature data. ...

Optimum price of electricity in thermal-generating station under deregulation
The deregulated market is characterised by a number of power producers trying to sell electric power through bilateral agreements or power exchanges. Each utility follows its own pricing strategy and causes more price volatility and makes comparison difficult. This paper presents a general model to determine the optimal Electricity Price (EP) at the generator end point which motivates investment ...

Co-production of synthesis gas and power by integration of Partial Oxidation reactor, gas turbine and air separation unit
A new synthesis gas production process based on partial oxidation (POX) of natural gas is investigated. Synthesis gas and mechanical power are generated in a plant that integrates a POX reactor, a synthesis gas turbine and an air separation unit. The synthesis gas is expanded in the turbine which runs the air separation unit. By means of an exergy analysis, it is shown that the synthesis gas ...

Power generated from methane gas in disused mines in England
Type HOFGAS®-IPM/C 2500 Performance 2’500 Nm³/h / 520mbar dP Location England (GB) Situation Mine gas is released when coal is extracted. This gas is sourced not only from working coal mines but also from those that were closed down long ago. Because large quantities of coal remain in the mine after it has ceased production, mine gas is released afterwards. The high proportion of ...
