Solving problems in packed absorption using Mathcad®

The techniques for solving problems in packed tower absorption are very dated.These techniques have been subjected to a host of different approximations.Much of these calculations are very slow and tedious.The procedures dated back to the time when the primary means of computation was by slide rule and mechanically drawn graphs.Engineering students were well versed in the use of the slide rule and were taught engineering drawing.The present age is the age of the computer and the old techniques are no longer needed.The computations for packed tower design are an enigma and are very difficult for the modern engineering student.Most of the procedures that were used to determine the required height of a column packing required some form of graphical integration.The curves that were plotted often have great curvature at some location and it was often extremely difficult to obtain any accurate results.
