2. Identify energy resources and waste heat emissions

2.1 Phase 1: representation of a process

In the Material and Energy Flow Diagram for a process, the incoming material flows (in blue) into the process are defined, for each flow, by:

• the type of fluid, characterized in particular by its heat capacity if the fluid is in a vapor or liquid state, its latent heat if the fluid is capable of being vaporized or condensed;

• mass flow rate;

• the initial temperature of the flow and the target temperature (that of the Tpr process).
