Numerical study on the thermodynamic performance of a packed bed cryogenic energy storage system

Latest technological advances and insights into capture and removal of hydrogen sulfide: a critical review

“…Cryogenic packed bed (CPB) is a combination of cryogenic and packed bed separation methods. 385 The CPB separation begins with the cooling of the packed bed column with liquid nitrogen until the temperature reaches −120 °C, switched with the sour gas feed after the cooling process is completed. After the packed bed is sufficiently cooled, crystals will be formed from the sublimation of H 2 S and CO 2 , and condensation of water molecules.…”

CFD-DEM Modeling of Cryogenic Hydrogen Flow and Heat Transfer in Packed Bed

“…The heat transfer coefficient is very important in the process of heat transfer. Tan et al [4] used numerical simulation to study the thermal performance of the cryogenic storage thermal system of the packed bed. The working fluid was nitrogen.…”

Cryogenic Process Optimization for Natural Gas Purification: Predictive Modeling of Methane–CO2 Solid–Vapor Phase Equilibrium Using Response Surface Methodology

“…However, extensive research into this method was widely believed to be unfeasible due to the large cooling duty . However, recent studies in cryogenic separation have demonstrated that this method can be competitive with alternative technologies with energy integration and careful adjustment of process parameters. − …”
