Heat Integration Heat integration is a technique used to integrate heat duties of the process. Also, it is applied to heat exchanger network (HEN) to find if there are possibilities of reducing utilities, and as a result of reducing utilities, the cost of utilityβs stream will be reduced. For heat integration, a useful technique used to integrate heat is called pinch analysis.
Pinch analysis is a technique used to find minimum cooling utility (Qc), and minimum heating utility (Qh) that are needed in the process.
Figure 140: Temperature vs Enthalpy for hot and cold composite curve.
Figure 1 shows temperature vs enthalpy for both hot and cold composite curve. This figure is being plotted by first tabulating all inlet and outlet temperatures for hot and cold stream which will allow finally to find the energy targeted value.
