主　　题：Heat-integrated distillation system Optimization approach Optimization problem Process industry 

摘      要：Process optimization plays an important role in design, operation, control and computer integrated control of process industries. This paper presents the description of steady-state optimization, dynamic optimization, and the optimization of process structures based on changing market conditions in process industries. Characteristics of these optimization problems are addressed and state of the art solution approaches are proposed. Sequential quadratic programming and orthogonal collocation is used to solve the dynamic optimization problem. Finally, the dynamic optimization to minimize the energy cost of a heat-integrated distillation column system is illustrated as an example.
