“…Implementation of sub-systems helped solving large-scale HLD problems, which are often computationally expensive. Bade and Bandyopadhyay [34] worked on a method to minimise the flow of a hot oil circuit between two plants. Although pumping and piping costs were not considered in the objective function, they were indirectly minimised by selecting the lowest possible hot oil flowrate.…”

The large potential for waste resource and heat recovery in industry has been motivating research toward increasing efficiency. Process integration methods have proven to be effective tools in improving industrial sites while decreasing their resource and energy consumption; however, location aspects and their impact are generally overlooked. This paper presents a method based on process integration, which considers the location of plants. The impact of the locations is included within the mixed integer linear programming framework in the form of heat losses, temperature and pressure drop, and piping cost. The objective function is selected as minimisation of the total cost of the system excluding piping cost and -constraints are applied on the piping cost to systematically generate multiple solutions. The method is applied to a case study with industrial plants from different sectors. First, the interaction between two plants and their utility integration are illustrated, depending on the piping cost limit which results in the heat pump and boiler on one site being gradually replaced by excess heat recovered from the other plant. Then, the optimisation of the whole system is carried out, as a large-scale application. At low piping cost allowances, heat is shared through high pressure steam in above-ground pipes, while at higher piping cost limits the system switches toward lower pressure steam sharing in underground pipes. Compared to the business-as-usual operation of the sites, the optimal solution obtained with the proposed method leads to 20% reduction in the overall cost of the system, including the piping cost. Further reduction in the cost is possible using a state of the art method but the technical and economic feasibility is not guaranteed. Thus, the present work provides a tool to find optimal industrial symbiosis solutions under different investment limits on the infrastructure between plants.

“…Another aspect overlooked in the literature is the type of the intermediate fluid which is used in inter-plant exchange. Methods have been specifically developed for heat sharing by steam [11], hot water [38] or hot oil [34]. Thus, the gaps in the literature are identified as:…”

“…Use of a fluid with a higher heat capacity will result in lower pumping costs, possibly decreased safety concerns due to spillage and simplification of control [63]. Use of heat exchange mediums other than steam, such as thermal oil to minimize the flow rate for indirect interplant integration, was investigated by Bade and Bandyopadhyay [129]. The use of heat recovery loops (HRLs) with thermal storage have been proposed for indirect heat transfer between individual plants with low pinch temperatures [130].…”

“…Bagajewicz and Rodera proposed an MINLP model to determine the minimum number of oil circuits in heat integration across plants. Bade and Bandyopadhyay presented an LP formulation to minimize the heat flowrate of thermal oil to transfer interplant heat at minimum total utility consumption. Based on pinch analysis, Chang et al concluded that thermal oil can transfer sensible heat and thus enhance heat recovery efficiency than steam.…”

Intermedium agents play an important role in indirect interplant heat integration. Each of them has a unique performance in heat recovery, however seldom conjunctively employed, which simplifies the problem but limits the extent of heat recovery. Thus, in order to fully exploit the potential of cascade heat recovery across plants, this work presents an optimization-based method to perform the automatic selection and arrangement of intermedium fluids in their integration with each single plant. A total site heat exchanger network superstructure model of possible configurations combining the allocation of medium streams (multiple agents and multiple circles) across plants and the heat exchanges between intermediate fluids and inner-plant process streams is proposed. For single-period concerns, the generalized model is formulated into a mixed-integer nonlinear programming problem to perform the network optimization at minimum total annualized cost target. Beyond this, the multiperiod problem is further studied to accommodate the time-related variations in the long operating horizon of an industrial park, and a robust network is achieved with updated modeling. Finally, a numerical case is illustrated in several scenarios; the significant drop in network cost shows the effectiveness of the method and the extended application of the method in a multiperiod design is also presented.
