A comprehensive approach to chemical engineering computational problems

A general programme for the solution of large sparse systems of non-linear equations is presented that allows to afford in a general way most computational problems in chemical engineering.Equipments and plants can, in fact, be represented as networks of “unit cells” to which material and energy balance equations are applied in finite form.The lay-out of the network and the assessment of the equations is a matter of the engineer's judgment and depends upon the aims of the computation and the complexity and importance of the phenomena involved.The solution of the equations then becomes a straightforward procedure that may be committed to the computer.Examples of application to a variety of chemical equipments and to process computation are given.
