In spite of the fact that tremendous progress is being made in understanding the performance of both random and structured packings in distillation, it is a long way from being able to predict from first principles, the efficiency, capacity and pressure drop of a tower packing using thermodynamic and thermo-physical properties of the chemical system being distilled, as well as the physical parameters of the packing which aids the mass transfer.

Automatic control systems have advanced far from their initial applications in the process industries. The conversion from local single-input single-output loops through initial application of advanced methods to current multivariable, adaptive, and neural network applications has increased plant profits. Petroleum refineries, petrochemical plants, gas processors, and other industries all benefited from control system improvements.
