HITREAT™ is a modular CO₂ processing solution designed to treat CO₂ captured from industrial sources. It combines processing steps such as compression, purification, dehydration, and liquefaction to deliver CO₂ in the required purity and phase, whether gaseous, supercritical, or liquid. The system can remove impurities including sulfur compounds, nitrogen compounds, water, hydrocarbons, heavy metals, and air gases, making it suitable for transport by road, rail, or ship and for various downstream applications.
