Integrated Approach of Intelligent Asset Maintenance and Resource Conservation for Circular Economy
Chin, Hon Huin ; Ditl, Pavel (oponent) ; Hanika, Jiří (oponent) ; Kravanja, Zdravko (oponent) ; Klemeš, Jiří (vedoucí práce)
The rapid global industrialisation and urbanisation have placed heavy burdens on natural material resources consumption. For example, water scarcity and water pollution have been affecting human lives and economic developments for a long time, and resorting to clean fresh water has been becoming an important issue. The increasing irregular water supply and water pollution issues require more advanced water resources assessment methodologies to guide practical water use and management. Another well-known issue is the plastic waste accumulation in the option, which raises an alarming concern in achieving the optimal resources conservation network, striving towards the goal of Circular Economy. The Circular Economy concept not only focuses on resources conservation but also highlights the importance of maintaining and preserving the assets’ lifetime. This thesis is focused on developing advanced approaches for resources conservation and asset maintenance This thesis presents the extended analysis of Pinch-based methods in conserving the material resources for an industrial site. The major extensions involve the conceptual analysis on the resource conservation network that involves multiple qualities constraints, headers targeting and synthesis, and Total Site material conservation network synthesis. These methods serve as the graphical user interface for the users to select the preferable design options while ensuring the fresh resources consumptions are minimal. The study also extends the incorporation of different types of resources, such as heat and water, into the conservation network. The management issues such as resources management, subsidies and cost allocations are also studied for the eco-industrial site. Considering the asset’s lifetime prolongation, the long-term planning of a process or industrial site is incorporated in this study covering the assets’ age, depreciation and reliability. Process Integration tools are proposed to plan for the maintenance cost for a time period and workforce scheduling. The study is also extended to more analysis involving standby units and technologies investment for any process. Combining asset performance with resources conservation, the fault diagnosis and prognosis framework is applied to the Total Site/Eco-industrial park asset maintenance planning.
