Natural gas processing is a critical step in the energy value chain, transforming raw natural gas from production wells into usable products for industrial, residential, and commercial applications. Compressors play an integral role in this process, ensuring the efficient movement of gas through pipelines and facilities. Among the leading names in gas compression technology is Ariel Engine, known for its robust and high-performance compressors.
In this article, we explore the diverse applications of Ariel Engine compressors in natural gas processing, their technical advantages, and how they contribute to efficiency, safety, and sustainability in the energy sector.
Understanding the Role of Compressors in Natural Gas Processing
Natural gas, as extracted from reservoirs, contains impurities such as water vapor, hydrogen sulfide (H₂S), and natural gas liquids (NGLs). Processing facilities are responsible for purifying the gas, separating valuable components, and preparing it for distribution. Compressors are essential in this chain, facilitating various stages of gas handling, including gathering, treatment, storage, and transportation.
Key stages where compressors are utilized include:
- Gas Gathering: Compressors collect raw gas from multiple wells and deliver it to processing facilities.
- Gas Treatment: Compressors maintain pressure during processes such as dehydration, sweetening (removing H₂S and CO₂), and mercury removal.
- NGL Extraction: Compressors aid in separating heavier hydrocarbons like propane, butane, and ethane from the natural gas stream.
- Transportation: Once processed, compressors pressurize the gas for transportation through long-distance pipelines.
Ariel Engine compressors are widely deployed across these stages due to their unmatched reliability and performance.
