The object of this step is to collect the mass and energy data corresponding to the steady-state operation of the process under investigation. This data can be provided as steady-state simulation results (for example, from commercial simulators such as Pro II, Aspen, HYSYS, or ICAS simulator ) or operational data collected from the plant. Therefore, the methodology can be applied to any chemical process, for which steady-state operational data is available. Also the cost data related to prices of chemicals, utilities, etc., need to be specified in this step.
