Rigorous and short-cut design calculations for gas absorption involving large heat effects. II. Rapid short-cut design procedure for packed gas absorbers
A short-cut design procedure was developed allowing the quick approximate design of nonisothermal packed gas absorption columns by hand. The method is not based on simplifying assumptions but on a correlation of a large number of rigorously obtained liquid temperature profiles. The rigorous computations include a wide range of system properties and operating conditions. Correlation of the liquid temperature profiles was possible by correlating the temperature of the exit liquid and a temperature associated with the internal temperature maximum separately. Also, the need for graphical integration in cases with equilibrium lines curved due to the temperature variations was eliminated by replacing the curved equilibrium line by two straight lines and correlating the slopes of those lines. The proposed method is more reliable than the conventional approximate calculation methods based on simplifying assumptions and is often even less time consuming.
