INTRODUCTION

Gas turbo expanders by Turboden - Introduction

Turboden gas expander is a solution to enhance the energy efficiency of a natural gas network infrastructure, producing electricity by taking advantage of the reduction of gas pressure from the delivery level to the one required by users, be they residential or industrial.

KEY POINTS

  • Design based on 40+ years of experience, leveraging Mitsubishi Heavy Industries support
  • Long experience in the energy efficiency sector
  • Profit generation while reducing the gas pressure
  • Solution for natural gas network decarbonisation
  • Unmanned installations, thanks to specific technology features
  • Turn-key equipment capabilities
  • Over 60 Turboden turbine models within the 400 power plants fleet

THE SOLUTION

 

Natural gas turboexpanders reduce gas pressure from the delivery level to the one required by users, be they residential or industrial.

Unlike common pressure regulators (still present in by pass to the turboexpander, for safety reasons, as a redundant system), the turboexpanders exploit the pressure drop to produce electricity , improving the energy efficiency of the entire gas distribution system.
