Heat integration to minimise energy usage in multipurpose batch plants has been in published literature for more than two decades. In most present methods, time is fixed a priori through a known schedule, which leads to suboptimal results. The method presented in this paper treats time as a variable, thereby leading to improved results. Both direct and indirect heat integration are considered t...

Energy efficiency in industrial field gains very much attention around the world. Total Site Heat Integration (TSHI) is proposed as a solution to increase energy saving opportunities. Graphical method, numerical method and mathematical model are used to benchmark, design and optimise centralised utility system in multiple processes site. Several publications have studied multiple utility target...

In the simultaneous heat and power integration approach with additional production the optimization problem is formulated using superstructure. Nonlinear programming (NLP) contains equations enabling structural and parametric optimization. In the present work the NLP model is formulated with the optimum energy target of the process integration and generation of electricity using a gas turbine. ...

A thermal response model for designing a hybrid thermal energy storage (TES) heat sink is developed. The stabilization time and maximum operating (hot side) temperature-totransition temperature difference are used to characterize the performance of the heat sink. The thermal properties of the PCM employed in the design are investigated. Integration of a design optimization algorithm into a ther...

In this paper, numerical simulations of coupling phenomena including flow of thermal fluid and heat transfer in solid are performed. To simulate the coupling phenomena, the flow and the heat transfer in solid are computed simultaneously by the solving of the same governing equations in which the flow velocity in the solid region is set to zero. As examples of numerical simulation, the phenomena...

A thermal response model for designing a hybrid thermal energy storage (TES) heat sink is developed. The stabilization time and maximum operating (hot side) temperature-to-transition temperature difference are used to characterize the performance of the heat sink. The thermal properties of the PCM employed in the design are investigated. Integration of a design optimization algorithm into a the...
