This work presents a dimensionless analysis of mass transport equations in fixed-bed absorbers. Focus is centered in isothermal and incompressible problems, with special attention to nonlinear adsorption and desorption processes that take place at absorbent particles. The general differential-algebraic equation system is expressed in dimensionless form, and the model is particularized into four different formulations. The model is analyzed and used to simulate a standard industrial test efficiently. Formulations are selected depending on the relative importance of the different physical phenomena involved in each part of test.
