ABSTRACT:
Disclosed is an apparatus and process for recovering heat from multiple hot process streams without multiplying instrumentation. Each hot process stream is indirectly heat exchanged with a water circuit which leaves and feeds a steam drum. Heat is added to the steam drum through the addition of water heated outside of the steam drum. The heated liquid and vapor water is heated in heat exchangers decoupled from the steam drum. The water circuits are arranged in parallel with each other and feed a single steam drum to provide a steam product of a desired pressure for which only one set of instrumentation is needed.
