Since many different raw materials must be taken into account, the program is very flexible in this regard. To this end, a computer program, Pyrosim, was developed by the author to calculate predictive steady-state mass and energy balances for a wide variety of processes. The essential problem of process simulation involves the development of a technique that will allow the prediction of the outcome of a particular process under specified operating conditions. Computer simulation allows the requirements of a particular process to be determined quickly and reliably. Because experimental work in pyrometallurgy is expensive, a system should be characterised as thoroughly as possible before experimental work is undertaken. Pyrometallurgical processes must be evaluated at many stages during their development and design, and when operating changes are introduced. These processes can be extremely complex, involving reactions between gas, solids, liquid slag, and liquid metal (and sometimes other phases as well).
Pyrometallurgical operations are essentially concerned with the high-temperature processing of materials.
Pyrosim provides a convenient framework for the calculation of material and energy balances, as well as a simple basis for cost comparisons between process options. This predictive ability allows the program to simulate novel processes rather accurately. One of the primary strengths of the program is its built-in capability to calculate multi-component multi-phase equilibria, along with the automatic performance of energy-balance calculations. The program uses a variety of models to predict the flowrates and analyses of product streams, as well as the distribution of elements between phases. Synopsis: Pyrosim is a general-purpose computer program for the steady-state simulation of pyrometallurgical processes.
