Knowledge-Driven Reactor Network Synthesis and Optimisation
نویسندگان
چکیده
The limitations of existing methods for reactor network synthesis, including the more robust stochastic optimisation based methods, to cope with complex reaction schemes involving highly non-linear kinetics and multiple reactions, requires a novel approach to the problem. This paper uses knowledge derived from fundamental kinetic information to compose design rules representing the dominant design trends that lead to high system performance. This is the basis of a customised optimisation algorithm that features rule-based move selection to guide optimisation towards the most promising spaces, achieving more effective knowledge-based decision making. Results show optimal solutions obtained for an illustrative example agree with published literature whilst achieving better convergence compared to standard stochastic optimisation-based methods.

On the development and implementation of knowledge- driven optimisation schemes: an application in non- isothermal reactor network synthesis
Knowledge driven optimisation has been developed in an attempt to overcome difficulties in applying existing reactor network synthesis methods to complex systems. Knowledge derived from kinetic relationships is applied to superstructure optimisation in the form of a customised rule-based Tabu Search where rules are used to guide optimisation decisions. Nonisothermal behaviour is represented usi...

The paper presents a systematic approach for the extraction, interpretation and exploitation of design knowledge in process synthesis. Knowledge is developed in the course of superstructure optimisation. Semantic models (ontologies) and analytical tools are combined to simplify the superstructures and interpret solutions. In the course of the search the method translates intermediate solutions ...
