Croft’s All-in-one Fuel Gas Conditioning System

fuel gas conditioning

The Fuel-Gas Conditioning System is a unique, skid-mounted hybrid unit designed to remove water and high BTUs for compressor fuel and instrumentation gas, but is not limited to small well streams. We utilize these systems in various applications, including polishing gas and processing rig fuel, as well as at compressor gathering points. The Fuel-Gas Conditioning System is a combination of multiple Croft systems combined into one package to condition fuel, supply, and instrument gas on location. The Fuel-Gas Conditioning System incorporates the Ambient Cooling System to cool the gas initially. The Joule Thomson System then removes hydrates and hydrocarbon liquids, lowering the BTU and reducing the water dew point. Lastly, the Passive Dehydration System® further reduces the dew point well below the pipeline specifications using Croft’s enviroDRI desiccant. Like any other Croft lease, this unit will have a 24-hour dedicated technician along with a 30-day service cycle.

This advanced equipment is designed specifically to remove particulates and free liquids from gas streams for utilization in high-speed gas engines and other bi-fuel applications that require a safe, clean gas.

FCS frequently asked questions

Why is fuel conditioning important?

Unconditioned fuel gas can contain:

  • Liquids and aerosols

  • Dirt, rust, and particulate

  • Compressor oil carryover

  • Inconsistent pressure and temperature

These issues can lead to poor combustion, equipment damage, unplanned downtime, and increased operating costs. A CROFT FCS helps eliminate these risks.

Are CROFT FCS packages customizable?

Yes. CROFT designs each Fuel Conditioning System to match your specific operating conditions, including:

  • Gas composition

  • Flow rate requirements

  • Operating pressures and temperatures

  • Site footprint

  • Applicable codes and standards

How does an FCS improve equipment reliability?

By delivering clean, dry, and stable fuel gas, CROFT FCS packages help:

  • Prevent fouling and plugging

  • Reduce wear on engines and turbines

  • Improve combustion efficiency

  • Lower maintenance frequency

  • Extend equipment life

Can CROFT help with system sizing and specification?

Yes. CROFT’s engineering team works closely with operators and EPCs to properly size and configure FCS packages for optimal performance and compliance with equipment manufacturer requirements.
