Hybrid simulation of a reacting distillation column

The recent availability of hybrid computers to the simulation engineer has made possible the solution of many complex reactor models that hitherto had to be either crudely approximated, or else required extremely long solution times on all-digital machines. Using the high speed of the parallel analog equipment and the logic and storage capabilities of a digital computer has meant that single blocks of analog equipment can be time-shared where physical similarity exists between process modules resulting in large savings in both analog equipment and running time.
