A Unified Approach for the Optimization of Energy and Water in Multipurpose Batch Plants

Water and energy integration: A comprehensive literature review of non-isothermal water network synthesis

“…Over the last couple of years several interesting studies have considered water and energy issues within batch process scheduling, where the main goal was to develop a methodology that could be applied for solving the overall problem including scheduling, and heat and water minimisation. Following this research direction, Halim and Srinivasan (2011) proposed a sequential approach in order to address water and energy optimisation during batch process scheduling, and later Adekola et al (2012Adekola et al ( , 2013 presented a unified framework for the simultaneous optimisation of water and energy in multipurpose batch processes by considering direct and indirect heat integration. Finally, Majozi (2013, 2014) presented an improved model for water and energy optimisation within a multipurpose batch plant.…”

Minimizing the Energy Requirement in Batch Water Networks

“…However, a few works based on mathematical programming have been proposed for energy and water minimization in the batch process. These include works by Halim and Srinivasan 37 who presented a method which minimizes water and energy sequentially along with batch process scheduling; Seid and Majozi 38 who addressed minimization of both water and energy, along with optimizing the batch process schedule; and Adekola et al 39 who developed a mathematical model to minimize wastewater and energy simultaneously in a batch process. A review of methodologies for water and energy integration for nonisothermal water networks is presented by Ahmetovićet al 3 From the above literature review it can be concluded that extensive graphical and mathematical programming based works exist in literature for continuous processes which considers both wastewater minimization and heat integration simultaneously.…”
