In this investigation, a natural-gas (NG) treatment system for NG sources with high CO2 content is simulated experimentally and theoretically using Aspen Plus. The concept uses patented heat exchangers and a process design developed as part of the cryogenic carbon capture(CCC) process to remove enough CO2 to enable the treated gas to be handled without the modification of traditional NG equipment. Simultaneously, the process removes liquefied natural gas (LNG) very efficiently. This process provides a simpler alternative to the solvent-based CO2 removal, absorbent drying, and cryogenic NG liquid extraction systems found in traditional NG processing. The data from an experimental bench-scale apparatus verify the results of the simulations as a function of NG composition and pressure. Costing parameters, exergy loss, and heat-exchanger efficiency are also discussed. The results confirm low exergy losses for bench-scale apparatus. The system uses heat exchangers with efficiencies of more than 90 %. High pressure and low methane content in the NG result in high CO2 capture.
