In many industrial processing activities such as oil refining, the synthesis of ammonia, and natural gas purification, CO2 and H2S (acid gases) are considered to be impurities. The acid gases must be reduced to prevent corrosion to materials and harmfulness to both the environment and human beings. The amine absorption technology is well-established in packed columns with numerous industrial installations and ready for large scale use. The hydrodynamics in the packed columns are one of the main issues in the offshore operation. Therefore, there is a need for a CFD model to investigate the effect of operating conditions on hydrodynamics, reactions and CO2 removal efficiency. The objectives of this project are:
To develop a three-dimensional (3D) CFD model for an amine absorber with structured-packing in the offshore operation.
To calculate the resistance of structured-packing.
To investigate the effect of operating conditions on hydrodynamics, mass transfer, chemical reactions, and CO2 removal efficiency.
Pressure drop, liquid holdup and CO2 concentration profiles.
Effect of vertical standing, static tilting and rolling motions.
