A DEVICE, METHOD AND SYSTEM FOR UN INTERRUPTED ABSORPTION OF GREEN HOUSE GAS (CO2) AND DE-WETTING HOLLOW FIBER MEMBRANE (HFM)

摘要

Disclosed is method for achieving higher CO 2 capture efficiency from flue gas/syngas from coal fired power plants/IGCC based plants in Hollow fiber absorber by de-wetting Hollow fiber membrane absorbers periodically. The two trains of hollow fiber membranes are employed in which one train is used for CO 2 capture at a time and other train undergoes membrane drying process. The hollow fiber membrane is dried by flue gas/hot air/CO 2 gas. Another method to reduce wetting rate of hollow fiber membrane by maintaining pressure drop across the membrane is also disclosed.
