Abstract
A method and system for maximizing heat recovery in a heat exchange network includes collecting on-line process data from a network of heat exchangers having multiple parallel paths. The on-line process data is generated from cool process stream outlet temperatures of the paths. Stream flow rate target values are developed based on the on-line process data and include intended flow rates through each heat exchanger to equalize each of the cool process stream outlet temperatures. One or more cool stream flow control valves of the heat exchanger network and one or more process stream flow control valves of the heat exchanger network are controlled based on the flow rate target values to effect equalization of the cool process stream outlet temperatures.
