The gas expander system improves the energy efficiency of industrial plants by exploiting the reduction of natural gas pressure from the delivery level to that required by users.

An inlet gas line is entering the user’s site with high gas pressure. Normally, this pressure is reduced through reduction valves 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.

This system is suitable for industries with mass flow of natural gas from 1800 to 21000 Sm3/h and inlet pressure up to 50 bar.
