Abstract:

Considering the cluster effect of industrial park, it is expectable that could improve energy efficiency of the entire park by recovering the waste heat in each single plant via inter-plant medium fluids which absorb heat in some plants and release heat into other plants. Obviously, the selection of heat exchange medium and the setting of medium heat recovery loop will highly affect the optimal design of the waste heat recovery system and the energy-saving effect. Thus, other than single medium integration strategy, this work uses both hot water and thermal oil as mediums to implement the inter-plant waste heat integration. A heat exchanger network (HEN) superstructure coupling the matches between medium fluids and inner-plant process streams and the allocation of medium streams across plants is proposed. Accordingly, a mixed-integer non-linear programming (MINLP) model is formulated for network optimization aiming at the target of minimum total annual cost. At last, an example involving three plants is studied in three synthesis cases (single medium-single loop, single medium-dual loops, and dual mediums-dual loops). The effectiveness of the proposed method was verified by comparison.

Key words: inter-plant waste heat integration, medium fluid, heat transfer, optimization, system engineering
