- Pipeline Pressure System


The IsoGen System captures pressure energy and generates electricity from high-pressure fluid flows.

  • Up to 85% efficiency
  • Flexible enough to install multiple systems in parallel
  • Optimum efficiency possible with variable frequency drive (VFD)
  • Minimal changes to existing operations
  • No need for other instrumentation or ancillary equipment
  • Robust all-metal construction

Specifically designed for oil pipelines, pressure drops and the gas sweetening process, the IsoGen™ system is the most efficient turbogenerator on the market today with maximum flexibility.

In a perfect world, every pipeline route would be a straight line. But the world wasn’t built with straight lines. Pipelines have to travel up and down mountains and canyons to get oil and gas from the well to the processing plant. When liquid is transported downhill across large changes in elevation, it builds up a tremendous pressure that must be released. When the pressure is released, that energy is lost, forcing pipelines to run with less efficiency and profitability.

IsoGen by Energy Recovery was designed to meet this challenge and turn it into a way to cut energy costs. This new, unique technology replaces traditional choke valves with a system that not only reduces the pressure but also generates renewable energy.

The IsoGen system is a hydraulic turbogenerator that can be installed near oil terminals, pressure control stations, refineries or storage tanks—anywhere choke valves are currently used to release excess pressure.

The heart of the IsoGen system is a variable flow, single stage hydraulic turbine coupled with an asynchronous induction generator, which converts the hydraulic energy to electrical energy with up to 85% efficiency rather than dissipating energy through the choke valve.

The system is installed in parallel with the existing pressure control station or letdown valve, providing redundancy and reliability for the pipeline operation, as well as easy routine maintenance.

IsoGen offers a unique approach to creating renewable energy, as well as the ability to generate additional power without adding any risk to the operation.
