Conceptual design of wastewater treatment plants using a design support system

A case study showed the advantages of using a design support system during the design and retrofit of wastewater treatment plants (WWTP). The Manresa WWTP was chosen to demonstrate these advantages. While the records of the decision‐making process used during the Manresa WWTP design were not available to the authors, its original design objectives and the resulting structure and values for its more important variables were. A simplified but plausible design history focusing on the design decisions and not on the detailed modelling of the WWTP was generated with this information. Using such a design history it is possible (1) to evaluate automatically the compliance of alternative design proposals with respect to the design objectives; (2) to study the influence of the weight of the arguments in the selection of the most adequate proposal; (3) to document the decision‐making process; and (4) to assist the designer in the search of specific items within the historical records during the review of the current design or during the retrofit of the plant. © 2000 Society of Chemical Industry     

Molecular design of polymers

This presentation is centred on what the chemist can achieve by control of molecular structure to achieve the ‘simple properties’ in linear, synthetic polymers which make them useful in a modern industrial environment. Transparency is a desirable property, readily accessible with amorphous polymers. Rather special structures are required to produce transparent crystalline polymers in the bulk state. The utility of many polymers is restricted by their susceptibility to chain scission, leading to a drop in molecular weight and hence loss of mechanical strength. A structural approach to defeating this effect is to make ‘ladder’ structures. An approach to the synthesis of novel ladder structures by bi-nuclear regulated copolymerization is suggested. Although copolymerization has been widely studied, little systematic work has been carried out on copolymer systems, which are more difficult to attain, to study the effect of copolymer composition on physical properties. The results are not always those expected, as illustrated by the acrylonitrile/styrene system. An example for further research of this type is proposed. The problems of correlating molecular structure with mechanical properties in any quantitative way are formidable, although much progress has been made on the phenomenological level in the understanding of the physical behaviour of polymers. Attention is drawn to a correlation which has been observed between modulus and certain structural parameters which may open the way to quantitative studies. Toughness is a more difficult property even to define, let alone correlate with structure. Nevertheless qualitative correlations may provide a useful starting point for future research.

A computer-aided molecular design framework for crystallization solvent design

One of the key decisions in designing solution crystallization processes is the selection of solvents. In this paper, we present a computer-aided molecular design (CAMD) framework for the design and selection of solvents and/or anti-solvents for solution crystallization. The CAMD problem is formulated as a mixed integer nonlinear programming (MINLP) model. Although, the model allows any combination of performance objectives and property constraints, in the case studies, potential recovery was considered as the performance objective. The latter, needs to be maximized, while other solvent property requirements such as solubility, crystal morphology, flashpoint, toxicity, viscosity, normal boiling and melting point are posed as constraints. All the properties are estimated using group contribution methods. The MINLP model is then solved using a decomposition approach to obtain optimal solvent molecules. Solvent design and selection for two types of solution crystallization processes namely cooling crystallization and drowning out crystallization are presented. In the first case study, the design of single compound solvent for crystallization of ibuprofen, which is an important pharmaceutical compound, is addressed. One of the important issues namely, the effect of solvent on the shape of ibuprofen crystals is also considered in the MINLP model. The second case study is a mixture design problem where an optimal solvent/anti-solvent mixture is designed for crystallization of ibuprofen by the drowning out technique. For both case studies the performance of the solvents are verified qualitatively through SLE diagrams.
