Abstract: The main heat exchanger of an air separation plant is a multi-stream heat exchanger. The use of such heat exchanger type generally leads to substantial savings in energy and implementation costs. This work presents the main problems concerning multi-stream heat exchanger design. The analysis of such heat exchanger is performed using a thermodynamic concept used in heat integration, named pinch analysis

Keywords: air separation, multi-stream heat exchanger, heat integration
