TURBOEXPANDER CONCEPT 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...

TURBOEXPANDER TECHNOLOGY The core of the plant is a high-speed turbogenerator (1), which comprises a turbine and a generator placed on the same shaft into a hermetic enclosure. Natural gas exiting from the turbogenerator (1) is heading to the user’s supply line (2). Turbogenerator (1) produces high-frequency alternating current, which then is transformed by means of AC-DC-AC power converter (3) into alternating current with frequency and voltage requested by the national grid. The natural gas before entering the plant is cleaned via a filter (4) to ensure long-lasting and safe operation of all...

TURBOEXPANDER PLANT OVERVIEW Entire Plant High speed turbogenerator

TURBOEXPANDER RANGE Turboexpander system of Zuccato Energia is suitable for industries with mass flow of natural gas from 1800 to 21000 Sm3/h and inlet pressure up to 50 bar. The target power range is from 35 to 250 kW. The power range of Turboexpander is depend on the mass flow of natural gas and pressure ratio between inlet and outlet. The detailed information is presented in the table 2 and diagram 1: Table 2.
