Fuel gas conditioning skid-Everything you need to know

Fuel gas conditioning skid is a highly prioritized technology that generally pre-treats the natural gases and other ignitable gasses before infusing them into a basic cycle or a gas turbine generator. The main work that skid performs is treating natural gas into useable gases.  There are also two other functions it does – eliminate every single liquid drop and strong toxins from the gas and change the gas temperature to the injection requirements.

Various styles of filter elements are used in the process, especially in pressure vessels. The fluid impurities are gathered in a sump and automatically depleted from the system for performing easy and simple operations. Either electric or steam radiators can be used for the temperature change. The entirety of the system components and channeling are skid mounted for transport and installation.

At Multitex, we have immense experience in solving unique and exceptional problems for the last 35 years for various OEMs of Turbine/ Compressors, Pipeline Companies, EPC, and other consultants.

Process of Fuel gas conditioning skid

In Power, Gas, and Oil generation industries, there is a huge demand for fuel gas extracted from unnecessary solids and entrained fluids. The fuel gas must be heated to an adequate temperature to ensure that it reaches an edge over the gas’s dewpoint. The process is divided into several phases, and each phase is required to be treated under great determination.

If the gas is not properly treated with the use of a fuel gas conditioning skid, the gas cannot ship off the gas turbine engine. Improper treatment will lead to expensive repairs to the critical power generating equipment and can stall the manufacturing process completely.

Major specifications

  • Regulation – self-acting regulators
  • Separators and knockout drums
  • Metering – Orifice, Turbine, Coriolis, Vortex, Ultrasonic
  • Emergency shutdown & isolation valves
  • Pressure, temperature, & flow instruments
  • Filtration – liquid & solids removal
  • Heating – Used in dew point control

Regulation

Fuel Gas Conditioning skids are intended to protect natural gas fuel motors and turbines from solids, fluid slugs, and vaporizers. Additionally, with a blend of a heater, the fuel gas is superheated over the hydrocarbon and water dew point to prevent liquid buildup in the turbine’s condensation chambers. Our skid system meets the engine and turbine manufacturer’s fuel gas quality features by giving dry and clean fuel to level the existence of the equipment.

 Our regulation system works under guidelines as an essential part of the overall system to provide fuel gas at a safe & usable level. By gathering a fuel gas pressure reduction system into a process skid, we help limit field erection time.

Separators and Knockout Drums

Exclusive vane, multi-cyclone, or wire network type internals give high productivity evacuation of mass fluids. Multi-cyclone unit with a turndown of 4:1. Gas enters extraneously through a port that grants high outward force, removing solid and liquid particles against the cyclone’s mass that results in the separation of toxic particles from the gas. They can also be provided with mixing filters to have a better turn down.

Metering

The metering must be precise. For this uncommon kind of flow, meters like Coriolis or Ultrasonic stream meters are used.

The skids are provided with complete required instrumentation, valves, and channeling prepared for installation at site and charging after attaching with the rest of the plant at battery limits.

Emergency shutdown

The technology is made for the hazardous zone to keep up the temperature over the considering temperature after the pressure reduction valve extension or to provide superheat at the gas turbine delta. If the fuel gas conditioning skid uses a compressor or blower to boost the delta pressure, they are supposed to superheat or provide superheat.

Pressure, temperature, and flow instruments

The pressure is decreased close to the necessary pressure factor by passing the gas through the pressure reduction station. As the pressing factor is reduced, the gas cools because of Joule Thomson’s impact. This causes the precipitation of dampness just as hydrocarbon condensates. These are isolated in condensate separators similarly to the knock-out drum. The condensates are either gathered or disposed of.

Filtration

It is one of the important processes in fuel gas treating skid because it helps in the removal of liquid droplets from natural gas. This is accessible up to 0.008 ppm and 1 Μ. The channel module comprises a vertical vessel with equal mixing cartridges. Cartridges are made of borosilicate glass fiber and have an external filter layer of chemical-resistant polyester with stainless steel punctured plate backing and helical spring support. Gas flows out, and finally, the liquid is separated from the structure base.

Heating

As the temperature falls below the dew point, the gas requires heating. This is done in either “Indirect Water Bath Heaters (IDBH)” or “Electrical Heaters”. However, the need is to use Indirect Bath Heaters due to their safe working plan. Electrical Heating Skids are only used for low-limit plants.

Why is Fuel Gas Conditioning Skid important?

We have already discussed the important components of fuel gas conditioning skid. Commonly fuel gas contains a specific measure of common impurities. These pollutants may take numerous structures and cause harm to the gas turbine whenever left untreated. Gas conditioning is a filtration process structured to prevent this harm by eliminating these pollutants. A fuel gas conditioning system is expected to:

  1. Increase the average performance of the gas turbine
  2. Increase the life span of the gas turbine
  3. Meet guaranteed requirements
  4. Limit maintenance costs
  5. Diminish unscheduled damages
  6. Increase the overall performance of the gas engine and turbine

Different types of impurities remove while we treat Fuel gas

Here is a list of the major components that a fuel gas conditioning skid eliminates:

  1. Solids: Rust, Mill Scale, Sand

These solids, when left unchecked, can cause build-up or erosion in the gas turbine and related electric equipment.

  • Liquid: Water, Condensed gas, Heavy Hydrocarbon, Lube Oil

These fluids are so harmful that if these fluids aren’t removed, they may cause temperature changes inside the system and can lead to problems like a hot spot on the combustor.

  • Gases: Siloxane, Hydrogen Sulfide, Carbon Dioxide

These gases can lead to deposits, corrosions, and emissions. They can damage the capacity of the gas turbine, and the resultant pollutants can lead to the electronic system no longer being at consistent levels.

Benefits of a Fuel Gas Conditioning System in a process Skid

After discussing the importance, components, and their in-built pollutants, we have reached the stage of our final discussion, which is the key benefit. Fuel Gas Conditioning Skid offers several benefits for the manufacturing unit. In this part, we’ll discuss the major benefits received after installing a fuel gas conditioning skid system.

  • Quicker Installation
  • Noteworthy quality assurance
  • Excellent Safety
  • Greater Mobility
  • More Cost-Effective

By assembling these systems and delivering them straight to your premises, you can prevent downtime in the office and experience a quicker and more proficient fabrication or manufacturer process. This also gives you greater control over the climate and the finished results. It ultimately helps in managing the monetary and social reputation of the organization. Your processes also end up in the conservation of the environment and sustainable development.
