Abstract

In Natural gas pressure reduction stations, gas with a temperature of 15 °C enters to the station from transmission line, according to the Gas equation of state in constant volume as the gas pressure drops, the temperature drops too and this can cause condensation or frosting of gas compounds, resulting block in flow path. To avoid this phenomenon, the station inlet gas should be pre-heated before going to the regulators and pressure reduction process, using heaters installed in the station; the required energy for heaters supplied by station outlet gas, much of the heat from the burning gas is transferred to the environment through body and specially the stack. In this article it’s been tried to calculate the amount of wasted energy using the experimental results of field research and data collection from a sample heater of gas pressure reducing station in the city of Mashhad, by numerical modeling of the stack with Ansys software. The modeling and analyzing the results obtained from solving the model was determined daily 3.46Kwh energy as heat from the body and 55.2Kwh energy output from the stack to the environment is wasted, considering the heater’s functions on the year and many of these heaters in the whole country, considerable energy source can be retrieved.
