utilization for the purification process under consideration here is competitive with existing large-scale gas separation systems. In summary, the present concept offers very high process capacity, high CH4 recovery, high product purities, and competitive energy utilization. 3.8 Multistage purification process To further explore the possibility of enhancing the product purity beyond those reported in Figure 3.10, multistage purification scenarios are considered. Figure 3.12 shows a schematic of a staged purification setup based on present purification concept. The monoliths are arranged in series such that the two sink tanks from the first stage are modeled as the source tanks for the two second-stage monoliths. For this calculation, the intermediate mixing of streams is not considered and the flow of gas is assumed to follow a branching as shown in Figure 3.12. The first stage feed time is kept at the baseline value of 0.19 s, and product collection is assumed to continue until the liquid-gas interface in each monolith reaches the outlet, resulting in the highest possible recovery factors. The process model designed for one microchannel monolith is simulated for three microchannel monoliths with modified boundary conditions as shown in Figure 3.12. The two intermediate sink tanks, the product gas tank and the desorption gas tank, are designed to release the same amount of gas for the next adsorption stage as that collected from the first stage, so that the thermodynamic equilibrium between the stages is maintained. As an example, of 0.8242 kg kg-ads-1 of total feed gas supplied to the first stage monolith in a 0.19 s feed, gas collected in the intermediate product tank is 0.397 kg kg-ads-1, while rest of the gas is collected in the HTF sink tank. For a pressure drop of 100 kPa in the second stage, it takes 0.11 s to send the exact same amount of gas (0.397 94PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
