Because MEA absorption systems operate continuously and are scalable, the specific gas processing capacity is dependent on the MEA recirculation rate and the total volume of MEA used in these systems, the data for which are unavailable in the relevant studies. Luis (2016) reported a range of energy requirement from 0.88 to 1.52 kWh kg- CO2-1. Pirngruber et al. (2013) reported the energy requirement to be 1.03 kWh kg-CO2-1 for advanced MEA systems, while Bounaceur et al. (2006) documented it to be 1.67 kWh kg-CO2-1. This discussion shows that a direct comparison of specific CO2 removal capacity in the present concept and that of absorption systems is difficult. However, with the availability of CO2 specific energy requirement for these systems, it can be seen that the performance of the present concept approaches the performance of the most economical absorption system. Furthermore, the use of solid adsorbents instead of liquid absorbent makes the system durable, thereby reducing maintenance costs of absorbent replacement. As the system is modular, with its gas processing capacity dependent on number of microchannels, the concept is expected to be more versatile for a wider range of applications. As mentioned previously, the process consumes up to 97% of its energy as sensible heat, enhancing its utility in remote applications, where electricit y infrastructure is limited but low-grade heat supply is available. The nominal energy requirement values, when normalized with mass of CH4-rich product are even smaller than those of the absorption systems utilized for CO2 removal. The specific energy utilization for a 25 kPa pressure drop and 6% energy ratio is 0.68 kWh kg-product-1, which is lower than the reversible electrical input for the cryogenic distillation process for CO2 removal (1.0 kWh kg-CO2-1) (Göttlicher and Pruschek, 1997) and the advanced MEA absorption systems (1.03 kWh kg-CO2-1). Therefore, the energy 93PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
