This document discusses transferring fluid properties and component compositions between a parent flowsheet and sub-flowsheet in simulation software. It describes how the transfer basis is only important when the two flowsheets use different property methods, and how users can map component compositions across flowsheet boundaries using the Mapping tab. It also explains how to attach component maps to inlet and outlet streams to transfer components into or out of the sub-flowsheet, and confirms all components have been transferred using the Untransferred Component Info view.

1. Sub-Flowsheet Operations 2-23
2-23
The transfer basis only becomes significant when the sub-flowsheet and
Parent flowsheet fluid packages consist of different property methods.
Refer to Section 2.2.3 - Transfer Basis Tab for more Information.
2.5.4 Mapping Tab
You can map fluid component composition across fluid package
boundaries on the Mapping tab. Refer to Section 2.2.4 - Mapping Tab
for information.
Figure 2.16
To attach a component map to inlet and outlet streams, simply specify
the name of the inlet component map in the In to Sub-Flowsheet field
and the name of the outlet component map in the Out of Sub-Flowsheet
field of the desired stream.
Component Maps can be created and edited in the Basis environment.
Click the Overall Imbalance Into Sub-Flowsheet or Overall Imbalance
Out of Sub-Flowsheet button to open the Untransferred Component
Info view. The Untransferred Component Info view allows you to
confirm that all of the components have been transferred into or out of
the sub-flowsheet.
