Simulation and Experimental Studies of CO2 Capture from Gaseous-mixture Using Hydrophobic Ceramic Hollow Fiber Membranes
碩士 === 國立臺灣大學 === 化學工程學研究所 === 104 === In this study, a two-dimensional mass transfer model is developed to simulate the carbon dioxide transport for the hollow fiber membrane contactor in which mixed piperazine (PZ) and 2-amino-2-methyl-1-propanol (AMP) as the chemical absorbent is used. The model...
