The investigation of an SGT5-2000E gas turbine power plant performance in Benin City based on energy analysis

A novel empirical model for predicting the carbon dioxide emission of a gas turbine power plant

“…The natural gas use to powered the gas turbine power was supplied by Nigeria Gas Company (NGC) pipeline network in partnership with Seplat Nigeria Limited. The manufacturer-installed capacity of model SGT5-2000E was 153 MW output power at this site with a net heat rate value of 10,528 kJ/KWh at 26 °C [ 48 ].…”

“…Part of the power mechanical power produced by turbine is utilized by the air compressor, while the rest is converted to electrical power by the 3000-rpm generator. The synchronized electrical power is fed into the public power grid [ 49 ].…”

“…The compressor pressure ratio (r p ) was determined by applying Equation (11) as obtained from Refs. [ 49 , 54 , 55 ]. …”

“…The deviations in performances of the power plant that occur are owing to changes in the air properties entering the air compressor, such as relative humidity and temperature. Different ambient air densities and mass flow rates were computed applying Equations (16) , (17) , respectively, for various ambient air temperatures as expressed by Egware et al [ 48 ]. where T N is the absolute temperature, ρ N is the density and ṁ N is air mass flow rate for the nominal condition; T i is the absolute temperature, ρ i is the density and ṁ i is air mass flow rate for the off-design condition [ 48 ].…”
