In this paper, a new method is proposed for synthesis of property-based allocation networks. By analogy of concentration potential concepts proposed by Liu et al. (A heuristic design procedure for water-using networks with multiple contaminants, AIChE Journal, 2009; 55: 374-382) for the water-using networks, a new concept: the operator potential of sinks is introduced in this work. The operator potential of a sink is a measurement of the possibility of the sink to reuse the internal source streams. The sink with the lowest operator potential will be satisfied first. A literature example is studied to show the method proposed. The result shows that the method proposed in this work is very simple and the results obtained are consistent with those obtained in the literature.
