A rotating packed bed (RPB) is an innovative intensification technology that improves its separation capabilities in high-gravity conditions. This process increases efficiency with smaller equipment size and footprint than conventional packed columns. Although significant advancements have been made regarding RPBs, most studies only focused on single or dual rotor configurations in addressing dry pressure drop.

Novel or unconventional technologies are critical to providing cost-competitive natural gas supplies to meet rising demands and provide more opportunities to develop low-quality gas fields with high contaminants, including high carbon dioxide (CO) fields. High nitrogen concentrations that reduce the heating value of gaseous products are typically associated with high CO fields. Consequently, removing nitrogen is essential for meeting customers' requirements.

Natural gas demand has dramatically increased due to the emerging growth of the world economy and industry. Presently, CO and HS content in gas fields accounts for up to 90% and 15%, respectively. Apart from fulfilling the market demand, CO and HS removal from natural gas is critical due to their corrosive natures, the low heating value of natural gas and the greenhouse gas effect.
