Within the engineering phase of a metallurgical recycling plant, process modelling has been established as a powerful tool for supporting design work. Beside defining proper capacities for vessels and supply systems, a process model depicts the designated operation with enough accuracy to estimate economic figures. Furthermore, internal recycling streams can be considered, bottlenecks visualized, and possible operational challenges can be faced in an early stage.
A process concept is a visualisation of a designated metallurgical concept with basic unit data, as well as the major mass flows between the individual units. The process concept illustrates the efforts of establishing an additional production line. An off-gas treatment is a typical extension – which is especially recommended if a recycling of complex and/or hazardous elements containing raw material is processed.
