Fuel Gas Conditioning Systems

A fuel gas conditioning system is designed to purify fuel gas so that it can be more efficiently utilized by the gas turbine. An effective fuel gas conditioning system is crucial because it prevents damage to the gas turbine, increases the overall efficiency of the system and helps limit or avoid unexpected downtime. Combining the fuel gas conditioning system into an integrated modular process skid offers a number of added benefits in the form of speed, efficiency, cost, and more. Let’s take a look at several of the key points relating to fuel gas conditioning systems and how a process skid can help.

Why Is A Fuel Gas Conditioning System Important?

Above we briefly discussed some of the important functions of a fuel gas conditioning system and now we will take a closer look. Typically fuel gas contains a certain amount of natural impurities. These impurities may take many forms and cause a wide range of damage to the gas turbine if left untreated. Thus a fuel gas conditioning system is designed to prevent this damage by removing these impurities. A fuel gas conditioning system is needed to:

  • Increase the overall performance of the gas turbine
  • Increase the longevity of the gas turbine
  • Meet warranty requirements
  • Minimize maintenance costs
  • Reduce unscheduled downtime
  • Increase the overall reliability of the gas engine and turbine

What Types Of Impurities Are Removed Using A Fuel Gas Conditioning System?

Now that we have discussed the benefits and importance of a fuel gas conditioning system, you may be wondering what exactly it is that they remove that causes these benefits. In basic terms the impurities removed can be grouped into three categories according to their physical states: solid, liquid, and gas. Let’s take a look at some of the common impurities removed from each category.

Solids: Rust, Mill Scale, Sand

These solids, if left unchecked could cause a build up or corrosion in the gas turbine and related equipment.

Liquids: Water, Condensed gas, Heavy Hydrocarbon, Lube Oil

If these liquids aren’t removed they might cause temperature fluctuations within the system, such as hot spots on the combustor, or they could lead to emissions and deposits.

Gases: Siloxane, Hydrogen Sulfide, Carbon Dioxide

These gases can also lead to corrosion, deposits, and emissions. They can compromise the function of the gas turbine and the pollution they cause could lead to the system no longer being within compliance levels.

What Is The Benefit Of A Fuel Gas Conditioning System In A Process Skid?

The final important key point that we want to discuss is the ways in which integrating your fuel gas conditioning system into a process skid can be beneficial. Process skids offer a number of advantages over traditional models such as the following:

  • Faster Installation
  • Greater quality assurance
  • Greater Safety
  • More Mobility
  • More Cost Effective

The reasons for these advantages are that by completing them in our fabrication shops and then delivering them to you, it reduces the downtime at your facility, allows for a faster, more efficient fabrication process, and ensures greater control over the environment and overall quality of the finished results. Remember that STI Group is always eager to meet our customers’ varied needs and requirements and that we are happy to work with you in order to design a system that best fits your situation.
