Description:
A new algorithm has been developed for the steady-state simulation of multicomponent, adiabatic absorption in packed columns. The system of differential model equations that describe the physical absorption process is reduced to algebraic equations by using a finite difference method. This system of algebraic equations is then solved by using a block-tridiagonal matrix decomposition procedure. Both the physical model and the matrix solution method are discussed in the paper. Simulation predictions are compared with experimental results and with the predictions of an earlier algorithm. The new simulation procedure was found to perform quite well for the system studied and represents a considerable improvement over its predecessor from the standpoint of solution accuracy.
