METSIM was started as a metallurgical process simulation program, written to perform mass balance around the main unit operations of complex process flows. METSIM uses a set of computational methods to create an optimal combination of complexity, uptime, and computing resource utilization. METSIM is a general process simulation system designed to help engineers balance the mass and energy of complex processes. Plant design, capital costs and engineering evaluations all depend on these calculations. METSIM is the basis for the analysis of all chemical and metallurgical mass and energy balance processes.
