ECOS:Air Bottoming Cycle as the improvement of gas turbine engine in compressor stations
The Air bottoming cycle(ABC)is being considered as a compact and simple bottoming cycle in various applications.It consists of Gas Turbine(GT)as the topping cycle and ABC.Gas turbines are very popular in compressor stations.The popularity of this technology results from its advantages,the most important of which are: the fast start-up,high efficiency,low pollutant emissions,the short time needed for the installation to be constructed and a reasonable size.The ABC has similar features.The mechanical power obtained from the air turbine can be used either to support the gas turbine system or to generate electricity.Air turbine systems are simple in terms of operation.This results from the fact that there is no combustion process and there are no toxic agents or agents causing erosion or needing to be topped up.The ABC also improves the performance of the new combined engine in the off-design mode.The main feature of the GT(as well as GT-ABC)is a low water consumption.ABC configurations can be used to improve the efficiency of simple power units with gas turbines operating at locations without access to large amounts of water.For this reason,they can be used in gas transport and storage systems.The paper presents an application of the GT-ABC system with example configurations.Two gas turbines are selected as the topping cycle and compared to each other(the ABB GT10 turbine and the General Electric LM2500+RD turbine).The purpose of this paper is to show the thermodynamic potential of the GT-ABC system in a compressor station application.The significant increase in generated power and the relatively small amount of waste heat make this cycle very interesting.The improvement in energy efficiency involves a lower fuel consumption,which makes the cycle more environmentally friendly.A comparative economic analysis of the GT and the GT-ABC systems operating at a compressor station is performed.
