OPTIMIZATION OF PERFORMANCE TURBINE/COMPRESSOR IN THE GAS TURBINE COMPRESSOR FOR OIL AND GAS

Gas turbines mainly used in the power generators such as power generation and propulsion systems. Gas turbine mainly consists of three components namely turbine, compressor and combustion chamber. Turbine produces work from combine the compressed air in the compressor and heated inside the combustion chamber. Analyze performance of gas turbines depends on the thermodynamic properties such as temperature, pressure, air to fuel ratio and the Relative Humidity (RH). All the parameters are known then the thermodynamic analysis can be carried out for the gas turbine. In this research gas turbine are used for oil and gas circulation at Pertamina Gas Company regional of South Sumatra Indonesia (Pertagas). Pertagas Regional South Sumatra consist on three SKGs such as Benuang and Pendopo which has several engine components that serve to support the process of gas or fuel distribution. That component is gas turbine compressor and gas engine. This machine requires fluid water and oil to work properly. In addition to fluid, machine performance depends on the machine usage conditions and maintenance process. Performance machine can be known from the work efficiency of the machine and the amount of energy utilized. In this paper, experimental research is applied to calculated water consumption and oil, efficiency, energy utilization and vibration. The result shows that the amount of water and oil consumption is 36.8 water m3 /month and 635 oil/month. The efficiency of turbine is 0.94-0.96 and energy utilization factor is 0.7.
