“…Since the last eight decades, many research articles based on the steady‐state energy modeling of MSE have been published 3, 6–13. These articles represent a wide range of solution approaches for solving the set of nonlinear algebraic equations (SNLAE), such as different solvers (fsolver) 13, iterative methods (Gauss elimination, Gauss‐Seidel, Newton‐Raphson methods) 3, pinch analysis (composition and grand composition curve) 14, 15, the interior‐point method 16, genetic algorithms 17, differential evolution, particle swarm optimization 18, the water cycle algorithm 19, the artificial electric field algorithm 20, 21, etc., in the MATLAB environment. The introduction of different new deterministic (nonlinear programming) and stochastic approaches (metaheuristic approaches) to find the optimal value makes it essential to check the best solution obtained in the minimum time period.…”

The present work investigates the energy performance analysis of a heptad‐based multiple‐stage evaporator (MSE) under steady and transient conditions, integrated with different energy reduction schemes (such as steam split, feed split, and feed preheater). The steady‐state analysis was performed to optimize the steam economy subjected to the developed steady‐state energy models as the equality constraints. The simulated optimization is a maximization problem and is solved by Interior‐Point Optimizer and Gray Wolf Optimizer on two different platforms, GAMS and MATLAB, respectively. Further, transient and stability analyses were performed by developing and representing the nonlinear dynamic energy models to the state‐space representation using linearization.
