Abstract The aim of this case study is to develop a process model including both heat integration and separation processes by means of ASPEN PLUS simulation software. Previous studies have attempted to develop kinetic models or to retrieve optimal policies for operating the process multitubular catalytic fixed-bed reactor. This time a rigorous model is developed in ASPEN CUSTOM MODELER and expo...

The efficiency of MA recovery in the DIAMEX process has already been demonstrated using HAR. The next step aims at the demonstration of reprocessing from HAC as feed, in view of an industrial application. The volume reduction would reduce the size of the installation and thereby the costs of the process. The first step towards the demonstration of a DIAMEX process using HAC is the production of...

In order to design a process that operates close to tighter boundaries safely, much attention has been devoted to the integration of design and control, in which the design decisions, dynamics, and controlled performance are considered simultaneously in optimal fashion. However, rigorous methods for solving design and control simultaneously meet challenging mathematical formulations which becom...

This work presents a discussion of how to utilise well known methods from the field of experimental design in the flowsheet synthesis of energy systems. The work is based on an earlier work, where a methodology for improving large scale energy systems using a combination of simulation, experimental design and mathematical programming was presented. The methodology is suitable for synthesis of l...

Recently we showed that reinforcement learning can be used to automatically generate process flowsheets without heuristics or prior knowledge. For this purpose, SynGameZero, a novel two-player game has been developed. In work extend SynGameZero by structuring the agent's actions in several hierarchy levels, which improves approach terms of scalability and allows consideration more sophisticated...
