Scheduling and heat integration aspects of batch processes are addressed using unit-specific event-based modeling approach in this work. A mathematical formulation is proposed based on unit specific event based model for optimization of heat integrated batch plants.

OPTIMUM HEAT STORAGE DESIGN FOR HEAT INTEGRATED

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,

Heat integration in multipurpose batch plants using a

Jul 15, 2014 · Many current heat integration methods for multipurpose batch plants use a sequential methodology where the schedule is solved first followed by heat integration. This can lead to suboptimal results. In this paper, the heat integration model is built upon a robust scheduling framework.

Process integration as an optimisation tool in - CORE

Heat integration to optimise energy usage becomes a possibility if a process includes both heat generating and heat consuming operations. Heat integration in batch plants has in the past been largely disregarded as utility requirements are considered less significant due to the smaller scale of batch operations compared to continuous plants.
