“…Generally, the simultaneous optimization methods treat the transferred masses as decision variables to optimize single-component MENs. − Once the algorithm optimizes variables (such as transferred masses, flow rates, and split ratios), these optimized values are used to calculate specific parameters of the obtained MEN, such as the inlet and outlet compositions of each component and the number of trays. Essentially, throughout the calculation process, these optimized variables are treated as known values.…”

“…The SBS model defines mass exchange superstructure intervals based on the supply compositions of all streams, which is the main distinction between SBS and IBMS. Several other superstructure models have also been proposed, including block superstructure and stare-task-network superstructure. , Recently, Zhou et al introduced the node-based nonstructural model (NNM) for synthesizing single-component MENs. The NNM replaced the concept of “stage” in the SWS model with “node”.…”

In this study, a novel chessboard model with stream splits is proposed for mass exchange network synthesis (MENS) to achieve the minimum total annual cost (TAC). The proposed chessboard model presents a streamlined and concise representation of mass exchange networks (MENs), enabling adaptable configurations of streams. This model exhibits structural diversity and reduces the computational complexity of the MEN calculation. An improved stochastic algorithm called the random walk algorithm with compulsive evolution (RWCE) is applied to solve MENs represented by the chessboard model. The simultaneous method is employed to address three instances of singlecomponent MEN examples and a multicomponent MEN case study. The obtained optimal solutions outperformed the solutions previously reported in the literature. These findings demonstrate the viability and usefulness of the chessboard model with stream splits and the modified RWCE algorithm for addressing MENS.
