Incorporation of Eulerian–Eulerian CFD framework in mathematical modeling of chemical absorption of acid gases into methyl diethanol amine on sieve trays
Year: 2009
Abstract:
A two-dimensional mathematical model for removal of acid gases (H2S and CO2) by methyl diethanol amine in a commercial sieve tray column has been developed. The velocity profile in the liquid both in radial and axial ...
