The performance of various multicomponent hydrocarbon fuel gases in an absorption tower was evaluated via a computer simulated theoretical model. Three different systems, made up of CH4 to C10H22 at various compositions, were chosen for this study primarily to validate the computer models against reported field test data, and secondly, to avail of the limited existing vapor-liquid equilibrium and enthalpy data. Analysis of the gas absorption model was made to delineate the effect of system variables affecting the percent recovery of propane. Numerical results generated from the computer model were obtained by varying the following parameters: staging requirement, inlet gas and solvent oil temperatures, system pressure, gas to solvent ratio and the nature and purity of absorbing solvent. The conclusions derived were interpreted. The numerical algorithms used in general multicomponent-multistage operations as well as the limiting case of a single adiabatic flash absorber were presented. A full documentation of the resulting software programs was incorporated in a user's guide to facilitate usage and extension to other systems.
