TURBINE FEEDING
Introduction:
⠀⠀⠀
Gas combustion requires constant pressure and temperature at the inlet of the gas turbine combustion chamber. In addition, in this specific case, the natural gas to be sent into the gas turbine had to be treated first - to reduce the high concentration of heavy hydrocarbons and water - and heated to 28 °C above the dew point.

Advantages and features of the SAFE solution:
• Highly engineered integrated turnkey solution: Consisting of a single skid with a flexible and efficient compressor from another OEM – with a capacity of 3,000 kg/h and absorbed power of 350 kW at suction pressure of 1.48 bar g, inlet gas temperature of 36 °C and discharge pressure of 30 bar g – driven by an electric motor. In addition, to ensure that the gas temperature and pressure remain constant at the inlet of the gas turbine combustion chamber, the solution was equipped with the following technologies:
① Cross-flow heat exchanger and by-pass circuit to control the gas temperature.
② Pressure control system by means of gas recirculation.
• Maximum efficiency, reliability and safety thanks to the following auxiliary systems::
① Oil and condensate separation system at the inlet of each compression stage to avoid gas saturation.
② Air cooling system with dedicated sections at the discharge of each compression stage.
③ Pulsation damper for both suction and discharge of each compression stage
