CO2 RECOVERY TECHNOLOGIES

Rameshni & Associates Technology & Engineering (RATE) specializes in CO2 recovery solutions for upstream, midstream, and downstream applications, offering full performance guarantees. With extensive experience in gas processing from 20 MMSCFD to 5000 MMSCFD, RATE handles varying concentrations of H2S, CO2, and other components.

Rising global CO2 concentrations contribute to climate change, necessitating effective abatement strategies like Carbon Capture and Storage (CCS). CCS involves separating CO2 from industrial and energy-related sources, transporting it, and storing it long-term. RATE provides advanced technologies for post-combustion and pre-combustion CO2 capture, tailored to diverse applications.

RATE offers various CO2 removal depending on the applications that are summarized in this page. CO2 Liquefaction Process could be used with Pre and Post Combustion.

Liquefied CO2 Process can be designed as a modular compact package with the lower cost. The concept of liquefaction are commonly used in LNG application as one of main source of energy in the world. Therefore, CO2 liquefaction is well proven and economical concept that shall be considered as is applicable.

  • Carbon Capture and Storage (CCS) Approaches
  • CCS consists of three stages: CO2 separation, transportation, and storage. RATE supports three major CCS approaches:
  • Post-Combustion Capture: Ideal for retrofitting existing plants, allowing continued use of current combustion technologies.
  • Pre-Combustion Capture: Applied before combustion, often in integrated gasification systems.
  • Oxyfuel Process: Uses oxygen instead of air for combustion, producing a CO2-rich flue gas.
  • Post-combustion capture is often the first deployed due to its compatibility with existing infrastructure.
