Emerging Solvent Regeneration Technologies for CO2 Capture through Offshore Natural Gas Purification Processes

It is estimated that 40% of natural gas reservoirs in the world are contaminated with acid gases (such as hydrogen sulfide and carbon dioxide), which hinder exploitation activities. The demand for will increase by 30% from 2020 to 2050, rise industrial activities lifting travel restrictions. long-term production these high acid-gas fields requires mitigation plans, include capture, utilization, a storage process reduce emissions. Absorption one most established technologies CO2 yet it suffers extensive energy regeneration footprint requirements offshore operations. Therefore, aims this paper review analyze recent developments conventional emerging solvent technologies, packed-bed column, membrane contactor, microwave heating, flash drum, rotating packed bed, ultrasonic irradiation process. column drum less complex, minimum maintenance requirements, but suffer large footprint. Even though heating demonstrate higher flexibility stability, both require regular energy. Membrane contactor absorption systems compact, restricted various operational issues.
