adsorption. Zeolite 13X outperforms activated carbon because of its higher working capacity, lower purge requirement and higher equilibrium selectivity. Kikkinides et al was able to improve the purity and recovery of CO2 in a 4-bed 4-step process by allowing significant breakthrough of CO2 from the light end of the column undergoing heavy reflux after that recycling the effluent from this light end back to the column with the feed (Kikkinides, Yang and Cho). Chue et al. studied a 3-bed 9-step VSA process using activated carbon and zeolite 13X (Chue, Kim and Yoo). They concluded that zeolite 13X performs better that the activated carbon despite having a high heat of adsorption. Zeolite 13X outperforms activated carbon because of its higher working capacity, lower purge requirement and higher equilibrium selectivity. PSA cycle employing both heavy and light reflux steps were investigated by Takamura et al (Takmura, Narita and Aoki) and Park et al. (Park, Beum and Kim). Park et al. compared three different configurations of VSA process while Takamura et al. investigated a 4-bed 8-step VSA process. Although the pure CO2 rinse step improved the CO2 purity and recovery, it did not decrease the power consumptions. The power requirements for the 2-bed 6-step and 3-bed 5-step cycle were 106.91 kWh/tonne CO2 and 147.64 kWh/tonne CO2 respectively. However, the feed throughput was quite low (0.331 kgmol/hr) in those studies. Gomes et al. (Gomes and Yee), studied the 2-bed 4-step Skarstrom cycle. He did not employ vacuum to recover CO2. Their study also shows that the pure heavy component cannot be achieved by employing only the light reflux step. Chou et al. (Chou and Chen) studied two different PSA configurations consisting of 2-bed and 3-bed respectively. The 2-bed process did not have any light or heavy reflux 5PDF Image | Development of a Pressure Swing Adsorption (PSA) Cycle for CO2 Capture
