A homotopy-based backtracking method (HBM) for large-scale process simulation with load variations was proposed to improve the convergency of nonlinear algebraic equation solver. The fluctuated load variable was regarded as a homotopy parameter to make the auxiliary homotopy problem easily converge. In this paper,the homotopy parameter is searched by a backtracking method,which greatly improves the searching efficiency. With the Open Object Model Framework (OOMF) script language,the proposed HBM can be connected to solvers in Aspen Plus for the process simulation. The eraluation of the HBM were conducted via the simulation calculation of a large scale ethylene separation process with load variations. It is shown that the proposed HBM greatly enhances the convergency performance. It consistently converges to an optimal solution until it encounters an unsurpassable operation boundary. The backtracking method is also effective in searching homotopy parameter,solving auxiliary homotopy problem and analyzing flowsheeting bottleneck.
