Problem

The Equation Oriented (EO) method is available as a solution option in Aspen Plus. As always, the flowsheet is configured through the Aspen Plus Graphical User Interface (GUI). Flowsheet

connectivity is defined through the graphical process flowsheet and the Data Browser is used to configure the blocks and streams. EO requires additional input through the Data Browser.

Before you solve your flowsheet in EO, however, you must initialize it in SM. This does not require a complete solution to SM; however, a minimum requirement is that each block be

solved once. This provides initial values for the EO variables. How tightly the SM flowsheet needs to be solved to ensure a robust EO formulation is problem-dependent.
