Abstract :
The aim of this study was to analyze the performance of Omotosho Phase II gas turbine power plant for improved performance. To obtain the required output performance of the gas turbine power plant, operation data from years of 2013 to 2016 was collected
from Omotosho Phase II gas turbine power plant in Ondo State, Nigeria. ASPEN
HYSYS 2016 version was used to create two models, with one representing Omotosho
Phase II gas turbine power plant with fogging unit incorporated while the other
represented the power plant without fogging unit. The data was fed as input variables
into the models in ASPEN HYSYS 2016 version which simulated the power plant
process Specific Fuel Consumption (SFC) obtained from the power plant simulation
when fogging is not incorporated was 0.199 kg/kwh, whereas, SFC of the plant with
fogging was 0.179 kg/kwh. Thermal efficiency of 43.93% was obtained from the result
of the simulated power plant with fogging system, whereas, thermal efficiency of
39.39% obtained from the result of the simulated power plant without fogging system.
Net power of 131 MW was obtained from the simulation of the power plant with fogging
system while net power of 117.46 MW was obtained when the plant operates without
fogging system installed. For the compressor work, 82 MW/h was obtained from the
simulation of the power plant with fogging system, whereas, 112.11 MW/h was
obtained from the simulation of the power plant without fogging system. Furthermore,
turbine work of 213 MW/h were obtained from the simulation of the power plant
operating with fogging system while turbine work of 229.57 MW/h was obtained from
the power plant without fogging system. This indicates that the incorporation of fogging
system into Omotosho Phase II gas turbine power plant is economically viable in terms
of fuel consumption, efficiency, power requirement, and GHG emissions compared to
operation of the power plant without fogging system.
