Coverage of peak loads in electrical networks due to the utilization of pressure drop on the gas distribution stations

摘要

The reduction of natural gas pressure at gas distribution stations and points is associated with a loss of energy. Installing an expander to utilization of the pressure drop allows to use this energy. But due to a significant gas temperature reduction after the expander, it is necessary to increase the amount of fuel gas for preheating. The authors performed a fuel-economic calculation to compare the balance between costs and energy production in cash equivalents
