Abstract
The gas turbine stations are used in petroleum sector for different application, such as compressing of gas, pumping of crude oil or water, and power generation. The main parts of these stations are compressor, combustion chamber, and gas turbine. The compressor provides a compressed air for combustion process, and for cooling process of different parts of the station. The fuel (liquid or gas fuel) is injected into the combustion chamber to perform the combustion process. The resulted hot flue gases are passed to the gas turbine to convert its' thermal energy into rotational mechanical energy to operate the air and gas compressors, crude oil or water pumps, and to generate electricity. This work concerns with the applicability of utilizing the thermal energy content in flue gases exit from the gas turbine by adopting a field data received from one of the operating stations in north Oil Company in Iraq. The flue gases mass flow rate, and its' available energy have been calculated. Different operational conditions have been selected to produce superheated steam such as operating pressure range of (0.36-1.4 MPa), with a range of superheated temperature differs than the corresponding saturation temperature by (10-60 oC) for each selected pressure. This work is also concerned with the possibility of producing of hot water for a pressure range of (0.36-1.4 MPa) with a temperature lower than the corresponding saturation temperature by (5 oC). The results show that the power produced reaches (1.4-3.3 MW). Also the hot water produced reaches 90000 kg/hr at operating pressure of 0.36MPa. The obtained results in this work are interesting since an elimination of thermal pollution by exhaust gases is accomplished. The available energy in these gases has been utilized to produce either superheated steam or hot water without consuming a conventional fuel.
