CO2 Screw Compressor

Product Overview

The CO₂ Screw Compressor is a core power unit in carbon dioxide capture and processing systems. It is primarily used to efficiently compress captured CO₂ gas, providing a stable gas source for downstream processing, transportation, and storage.

The compressor offers a wide operating range, with flow rates from 600 to 15,000 Nm³/h and pressure ranging from 0.1 MPa to 3.0 MPa. It is suitable for various scales and complex operating conditions. With advanced screw compression technology, the system ensures high efficiency, low failure rates, and long-term stable operation, making it an essential piece of equipment in industrial CO₂ handling.

Working Principle

The compressor operates based on a twin-screw meshing principle. A pair of intermeshing rotors rotates داخل the casing, gradually reducing the volume of CO₂ gas in the compression chamber, thereby increasing its pressure.

The gas is continuously and smoothly delivered to the discharge end, avoiding the pulsation commonly found in reciprocating compressors. Optimized rotor design and precise clearance control improve volumetric efficiency and sealing performance, while also adapting to fluctuations in discharge pressure to ensure stable output.
