چکیده    This study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (sia-bc). in addition, use of turbo-expander as a good alternative to the expansion valves was also studied. performance of proposed cycles was investigated on a real case study for natural gas transmission network. results showed that the highest efficiency would be obtained with orc system where n-pentane was used as the working fluid and turbo-expander was considered in pressure reduction stations moreover, the efficiency improvement was estimated to be 22% averagely in comparison with the existing network where the flow was in the span of 50 up to 90 mmscmd.
