23 European Symposium on Computer Aided Process Engineering

The increasing costs of research and the decreasing lifetime of products and processes make the decisions on allocation of R&D funds strategically important. Therefore, ability to predict research trends is crucial in minimizing risks of R&D expenditure planning. The purpose of this paper is to propose a model for efficient prediction of research trends in a chosen branch of science. The approach is based on population dynamics with Burgers' type global interaction and selective neighborhood. The model is estimated based on a training set and an out-of-sample forecast is performed. The research trends of filtration processes were analysed in this paper. The simulation results show that the model is able to predict the trends with a considerable accuracy and should, therefore, be tested on a wider range of research fields.

An extended systematic methodology for the design of emulsion-based chemical products is presented. The methodology consists of a model-based framework involving seven sequential hierarchical steps: starting with the identification of the needs to be satisfied by the product and then adding one-by-one the different classes of chemicals, until a formulation is obtained, the stability of which as en emulsion is finally checked with appropriate models. Structured databases, appropriate pure component as well as mixture property models, rule-based selection criteria and

In this paper, a new control strategy that employs a mid-course correction to control the particle size distribution in emulsion polymerization is developed. In this approach, online and infrequent measurements are used to obtain the states of the system at the mid-course of the process. Then an optimization is performed to obtain the optimal trajectory of the input from the mid-course up to the end of the process. For this optimization, a hybrid model is used. This hybrid model consists

This paper proposes an ontological framework to support Industrial Symbiosis (IS) operation. The framework exploits semantic knowledge modeling and enables structural data transformation for identification of potential synergies between various industries and hence formation of one to one and complex symbiotic networks.

This work presents a multi-period waste management multi-objective optimization, considering economic and environmental issues. The specific behavior of the considered waste management treatments is included in the optimization problem as black-box models based on practical industrial practice computing utility requirements and emissions. To achieve more realistic solutions, the estimation of waste treatment costs and environmental impacts has been explicitly added to the assessment scheme, as well as the constraints of the operating conditions in the treatment units and the fulfillment

Based on a previously developed dynamic simulator, aimed to predict the distribution of a pollutant accidental discharge in a river segment, the present work investigated the way automatic measures may be implemented for counteracting their negative effects. The complex time and space distribution of the pollutant concentration in the downstream region of the pollutant release is revealed by the k-ε turbulence model of the flow, associated to the convection-diffusion-reaction processes. This information is used by the model based predictive control

Reliable models for rate-based phenomena are the backbone of model-based process design. These models are often unknown in the early design phase and need to be determined from laboratory experiments. Although model-based experimental analysis and process design are often executed sequentially, the kinetic models might not be suitable to reliably design a process. In this paper, we address this problem and present a first step on the integration of model identification and process optimization. Rather than decoupling model identification and

Dimethyl ether (DME) as a clean fuel seems to be a superior candidate for high-quality diesel fuel in near future. In this study, a comprehensive three-dimensional dynamic heterogeneous model developed to simulate the flow behavior and catalytic coupling reactions for synthesis of the DME from hydrogenation of the CO and CO2, dehydration of methanol to dimethyl ether and water gas shift reaction in a fixed bed reactor. For this purpose, a CFD simulation was articulated where the standard k-ε model

Uncontrolled changes caused many accidents or disasters. Management of change (MOC) has been a very important issue in process safety management. In this paper, it is considered that MOC is divided to two parts: one is individual change management and the other is management of them. Individual change management is an instance of engineering over the plant lifecycle (Plant-LCE), however a business flow of MOC has been hardly discussed. A business flow of MOC is expected to be based on

This study explores the best suitable internals and various feed configurations of a reactive distillation process for unsaturated polyester synthesis. Multi-product simulations were performed to find the operational parameters for producing different grades of polyester in the same equipment. The product transition time during product changeover is determined for various configurations and product grades. The selection criteria for the best configuration are the minimum requirements of volume and energy to produce 100 ktpy polyesters. The results of the rigorous simulations carried

In today's energy markets there is a growing effort in the alignment of the industrial sector to the power grid for the sake of efficient energy distribution and consumption. The steel making industry, as one of the most energy-intensive stakeholders, may play an important role in this context. In this paper, we use the Resource Task Network (RTN) in order to provide a generic modeling framework for scheduling problems under energy constraints. We study the impact of fluctuating electricity prices

This work introduces a methodology for the solution of reactive scheduling problems in small-scale fuel cell systems that cogenerate heat and power. The proposed approach successfully transforms the on-line optimization problem into a closed-loop control problem. In brief, a multiparametric programming problem is formulated and solved once and off-line, and afterwards a receding horizon-like approach is applied for the online scheduling by performing just function evaluations and avoiding on-line optimization. The proposed concept is promising and extensions can involve: large-scale

In this work, a model for the RAFT polymerization was developed in order to obtain the full molecular weight distribution (MWD) using probability generating functions (pgf). For comparison purposes, the population balances were solved by direct integration of the resulting equations. Our results show that the pgf technique allows obtaining an accurate solution while drastically reducing the required computational time.

This work presents a Computer-Aided Molecular Design (CAMD) method for the synthesis and selection of binary working fluid mixtures used in Organic Rankine Cycles (ORC). The method consists of two stages, initially seeking optimum mixture performance targets by designing molecules acting as the first component of the binaries. The identified targets are subsequently approached by designing the required matching molecules and selecting the optimum mixture concentration. A multi-objective formulation of the CAMD-optimization problem enables the identification of numerous mixture candidates.
