Gas Modular Skids

Reduced construction costs and shorter project timelines are critical in the gas industry. Modular solutions, such as gas modular skids, are increasingly being used to meet these requirements. Gas modular skids are prefabricated units with all critical gas processing and transportation components. 

These modular solutions can provide highly desirable results for specific capital projects. This article will discuss how gas modular skids are designed and used and answer general questions about their various applications.

Modular Process Systems FAQs

There are various modular process systems being utilized throughout the industry. Understanding their different applications is critical for selecting the best solutions for your capital project. This FAQ section answers frequently asked questions about gas modular skids and related systems.

How are Gas Modular Skids Used?

Gas modular skids are used in several applications, including gas compression, filtration, transportation, and metering. The main applications include:

• Compression: Boosting gas pressure for transportation and storage.
• Filtration: Removing impurities to ensure clean gas output.
• Metering: Accurately measuring gas flow rates for monitoring and billing.
• Treatment: Conditioning gas to meet quality standards before distribution.
• Transport: Facilitating the safe and efficient movement of gas between locations.

The Process of Creating Gas Modular Skids

Gas modular skids are pre-engineered, pre-fabricated units designed to handle specific processes within the energy and chemicals industries. Here’s a list of common applications for gas modular skids:

1. Gas Processing Skids

• Gas Dehydration Skids: Used to remove water vapor from natural gas to prevent pipeline corrosion and hydrate formation.
• Amine Gas Treating Skids: Utilized to remove hydrogen sulfide (H₂S) and carbon dioxide (CO₂) from natural gas.
• Molecular Sieve Skids: Employed for removing water and other impurities from natural gas using molecular sieves.

2. Gas Compression Skids

• Natural Gas Compression Skids: Used to increase the pressure of natural gas for transportation through pipelines or for storage.
• Booster Compressor Skids: Employed to boost the pressure of gas from lower-pressure sources for further processing or transmission.

3. Metering and Measurement Skids

• Custody Transfer Metering Skids: Used to measure the quantity and quality of gas being transferred between parties for commercial purposes.
• Flow Measurement Skids: Used to accurately measure the flow rate of gas within pipelines or during processing.

4. Gas Filtration and Separation Skids

• Coalescing Filtration Skids: Employed to remove liquid droplets and solid particles from gas streams.
• Slug Catcher Skids: Used to separate large volumes of liquid (slugs) from the gas before entering further processing units.

5. Pressure Regulation and Control Skids

• Pressure Reducing Skids: Used to reduce the pressure of natural gas to a desired level before further distribution or use.
• Pressure Relief Skids: Designed to safely release excess pressure to prevent equipment damage or catastrophic failure.

6. Gas Cooling and Heating Skids

• Gas Cooling Skids: Used to lower the temperature of gas after compression to meet pipeline temperature specifications.
• Gas Heating Skids: Employed to raise the temperature of gas, often before pressure reduction to avoid hydrate formation.

7. Fuel Gas Conditioning Skids

• Fuel Gas Conditioning Skids: Used to treat and condition gas for use as fuel in turbines, engines, or other combustion equipment.

8. Gas Blending Skids

• Gas Blending Skids: Used to blend different gas streams to achieve a specific composition or calorific value.

9. Vapor Recovery Skids

• Vapor Recovery Skids: Employed to capture and recover valuable vapors from storage tanks, pipelines, or process units to prevent emissions and increase efficiency.

10. Nitrogen Generation Skids

• Nitrogen Generation Skids: Used to produce nitrogen gas on-site for purging, inerting, or blanketing applications in gas processing and handling.

These modular skids are designed for flexibility and ease of installation, allowing for faster deployment and lower costs compared to traditional, on-site built systems. They can be customized to meet specific requirements and are often used in remote or offshore locations where space and infrastructure are limited.

Advantages of Gas Modular Skids

The advantages of modular construction apply to specific projects with unique modular drivers and requirements. In some cases, a traditional construction approach may be required. The choice between modular and stick-built construction, or a combination of the two, should be carefully considered and based on the project's specific requirements.
