A Liquid Ring Compressor (LRC) is a type of rotary positive displacement compressor that uses a liquid, typically water, as the working fluid to compress gases. The compressor consists of an impeller with blades that rotate inside a cylindrical casing filled with the sealing liquid. As the impeller spins, the liquid forms a ring inside the casing, creating chambers between the blades where gas is trapped and compressed.
Durability: LRCs have only one moving part and no metal-to-metal contact, which reduces wear and tear and extends their lifespan1.
Isothermal Compression: The liquid absorbs the heat generated during compression, maintaining a nearly constant temperature, which is beneficial for handling flammable or explosive gases.
Versatility: They can handle gas mixtures containing liquids or vapors without significant loss in capacity.
Low Maintenance: With fewer moving parts, LRCs require less maintenance compared to other types of compressors.
Handling Wet Gases: LRCs can efficiently compress gases that contain liquids or vapors without performance degradation.
Durability and Longevity: They are robust and can operate in harsh conditions, providing long service life with minimal maintenance.
Safety: The isothermal compression process reduces the risk of overheating and ignition, making LRCs ideal for flammable gases.
Design: LRCs use a liquid ring to compress gas, while screw compressors use two interlocking helical screws.
Efficiency: Screw compressors are generally more energy-efficient than LRCs, which can have efficiency limitations.
Application: LRCs are better suited for applications involving wet gases or gas mixtures with liquids, whereas screw compressors are preferred for dry gas applications
