Liu ZH, Macchietto S, 1993, Cleaning in place policies for a food processing batch pilot plant, Food and Bioproducts Processing: Transactions of the Institution of of Chemical Engineers, Part C, Vol: 71, Pages: 194-196, ISSN: 0960-3085
With reference to a multipurpose batch pilot plant, the definition of procedures for cleaning-in-place (CIP) and the tuning of relevant cleaning parameters are examined. A dynamic simulation model is utilized to establish first a cleaning control procedure which permits easier tuning of the spray-rinsing and wash cycles and draining parameters, for cleaning a single vessel. Then, a new procedure is developed for simultaneously cleaning N vessels in parallel in about the same time required for a single vessel, without increasing the CIP system capacity.
Odele O, Macchietto S, 1993, Computer-aided molecular design: A novel method for optimal solvent selection, Fluid Phase Equilibria, Vol: 82, Pages: 47-54, ISSN: 0378-3812
The task of selecting a solvent or solvent mixture with desirable combination of physical properties, to meet the needs of specific applications, has largely been tackled using a combination of heuristics and costly experimental studies. This material selection problem is here formulated as the combinatorial molecular design problem of choosing a set of structural groups making up a target molecule with the desired properties as predicted by available group contribution techniques. A novel mixed-integer nonlinear programming (MINLP) technique is used to solve the problem yielding compounds with optimum value of an appropriate performance index, subject to material balances, process and design limitations and feasibility of molecular structures. The strategy is applied with excellent results to solvent design examples for liquid-liquid extraction and multicomponent gas absorption using varying combinations of objective functions and constraints to reflect directly a multiplicity of operational objectives.

Barbosa Póvoa AP, Macchietto S, 1993, Optimal design of multipurpose batch plants 1. Problem formulation, Computers and Chemical Engineering, Vol: 17, Pages: S33-S38, ISSN: 0098-1354
A formulation is presented for the optimal selection of both equipment units and the network of connections for multipurpose batch plants so as to satisfy given production requirements for a variety of products. The model includes very general constraints and objective functions and permits to simultaneously optimise the structural aspects of the plant and the associated production schedule, accounting for both capital cost of equipment units and pipework, operating costs, and revenues. A special novelty of the formulation is that it provides the possibility of generating directly the optimal connectivity between process units, sizing and costing of all transfer lines, and the optimal storage policies (and associated vessel sizes, if any) for stable intermediates without the need for a priori assumptions (e.g. unlimited storage, etc). © 1992, Pergamon Press Ltd.

Bretelle D, Macchietto S, 1993, Dynamic simulation of a PVC batch reactor, Computers and Chemical Engineering, Vol: 17, Pages: S317-S322, ISSN: 0098-1354
A kinetic model was presented recently by Xie et al (1991) to describe the complex reactions occuring in the suspension polymerisation of vinyl chloride to polyvinyl chloride (PVC). The model had been obtained in laboratory conditions; nonetheless the author suggested that it could be used for design and operation of large reactors. In this paper, the dynamic simulation model of an industrial scale polymerisation reactor is presented, incorporating the above kinetic model but for slightly different process conditions. A number of changes were required, and several parameters in the model had to be adjusted to match the measured plant conditions. The process of identifying and fitting the parameters to be adjusted is detailed. The final model matches very well plant data for several product grades and initiators.The model is then used to simulate the entire reaction process, including startup, temperature control and shut down. The predictive abilities of the model are explored in some unusual conditions, including a runaway case, for which plant data were available. The use of the model for operator training is briefly discussed. © 1992, Pergamon Press Ltd. All rights reserved.
