Naturel Gas Pressure Reducing
European industries obtain about 1000TWh of energy annually by burning natural gas. This gas is transmitted via pressurized pipelines and while the pressure is reduced at the user’s gas letdown station, its potential energy is permanently lost.These losses are quantified as 400 MW of installable electric power.
Turboexpander operation
An inlet gas line (A) is entering the user’s site with high gas pressure. Normally, this pressure is reduced throughh reduction valves (B) and no useful work is produced. By installing a Turboexpander in parallel to the existing pressure reducing valves, it is possible to exploit this energy potential to produce zero-emission electricity.
