Compact Compression and Separation Unit (CSU)
Efficient compression and separation of gases and liquids
The Compact Compression and Separation Unit (CSU)® is an innovative technology designed for efficient compression and separation of gases and liquids. The CSU system is created to meet the demands of the modern energy industry, with a strong focus on sustainability, efficiency, and cost reduction.
The solution is applicable across multiple sectors, including hydrogen compression, carbon capture and storage (CCS), and oil and gas. The CSU unit provides a compact, lightweight platform that combines superior process safety standards with lower costs and reduced carbon footprint.
In a detailed study conducted in collaboration with Equinor in 2019, it was documented that CSU technology has the potential to reduce both capital costs and system weight by up to 50% and 40% respectively, compared to traditional solutions such as centrifugal compressors with inter-stage coolers and scrubbers.
