Abstract	A number of theoretical approaches exist for the design, improvement and optimization of CO2 capture from natural gas sweetening units through chemical absorption. Authors review the theoretical approaches developed by process and research engineers to improve the design and operation of chemical absorption sweetening units. The review is divided into four parts. The first part discusses the basic thermodynamic and kinetic principles that represent the main core of any process simulation research. The second part is devoted to designing and improving the main columns i.e., the absorber and the stripper. The third part reviews previous research aiming at designing or optimizing the whole sweetening unit. The last part briefly discusses computational chemistry techniques used by chemists and chemical engineers to design novel solvents at the molecular level.
