Multiple Cryogenic Packed Bed Dehydration and Separation ofC02 and Hydrocarbons from Natural Gas

A state-of-the-art methods for CO2 and water separation from natural gas is presented using multiple cryogenic packed beds. The main concept for such separation is the difference in freezing points on each component in natural gas stream. A series of pre-cooled beds for
separation of water, C02 and natural gas are used in this study. Both dehydration and C02 removal process are kept slightly below the freezing point ofwater and CO2, respectively. It will undergo desublimation process, where vapor directly change phase to solid. The remaining
components are unaffected and stay in vapor form. The dehydration process using cryogenic packed bed are studied in the temperature ranging from 0°C to -30°C. While the experiment for CO2 removal are studied at -70°Cto -100°C. The statistical optimizationofnatural gas separation are studied through simulation at high pressure and atmospheric pressure using cryogenic packed
bed.
