Use of computational fluid dynamics to model chemical process system has received much attention in recent years. However, even with state-of-the-art computing, it is still difficult to perform simulations with many physical factors taken into accounts. Hence, translation of such models into computationally easy surrogate models is necessary for successful applications of such high fidelity models to process design optimization, scale-up and model predictive control. In this work, the methodology, statistical background and past applications to chemical processes of meta-model development were reviewed. The objective is to help interested researchers be familiarized with the work that has been carried out and problems that remain to be investigated.

Chemical engineering subjects like reaction engineering, transport phenomenon, mass transfer and optimization contain very rigorous numerical and analytical data and equations. Many times the calculation from the equations and actual practical results are verified for consistency. Solving these equations manually is time-consuming and impractical. Many software tools are available for solving these problems. Unisim, MATLAB, Simulink, HYYS are few such tools. Simulation and optimization of the data can be carried out by using the mathematical concepts combined with these tools. The current review summarizes research and studies on the application of computer and software in chemical engineering practice and teaching.

A REVIEW OF SOFTWARE RELEVANT TO CHEMICAL ENGINEERING, 2023

The paper starts by highlighting the significance of software in chemical engineering, emphasizing its role in facilitating process modeling, analysis, and optimization. It outlines the primary software packages commonly employed in the field, including Aspen Plus:CHEMCAD, MATLAB, ChemDraw, Aspen HYSYS, ProSim Plus, gPROMS, Chemical (Microsoft Office Suite), Design of Experiment (DoE) Software, Open-Source Chemical Process Simulators and ColoSimulator and MiniTable: Computational Fluid Dynamics (CFD) Software:. Each software package is briefly described, highlighting its specific functionalities and applications. Furthermore, the paper underscores the relevance of these software programs in different aspects of chemical engineering. It highlights their contributions to process simulation, aiding engineers in accurately modeling chemical reactions, mass and energy balances, heat transfer, fluid flow, and multiphysics phenomena (Smith, J. D., Johnson, R. M., & Williams, A. L. 2022). The optimization capabilities of these software programs are also highlighted, enabling engineers to maximize process efficiency, minimize resource consumption, and reduce environmental impact. It also acknowledges the significance of process safety in chemical engineering and highlights the existence of specialized software for conducting hazard analysis, risk assessment, and safety evaluations. Additionally, computer-aided design (CAD) software programs like AutoCAD and Solid Works are mentioned, emphasizing their utility in creating detailed 2D and 3D models of process equipment and plant layouts. Conclusively, the paper emphasizes that chemical engineering software serves as a valuable resource for professionals in the field. By providing a comprehensive suite of tools for process modeling, simulation, optimization, and safety analysis, these software programs enhance the effectiveness and efficiency of chemical engineering practices.

The Chemical Engineering Science movement has served well in solving problems from micro to macro scales. Ultimately, as Professor R. Sargent pointed out, it would be better if translated in "Scientific Engineering". Examples of innovation as a combination of science (concept), technology and process/product will be presented. The first example is perfusion chromatography based on the concept of "diffusivity augmented by convection" and on the technology of fabrication of large-pore packings. The second example, Simulated Moving Bed (SMB), is based on a concept developed to overcome the difficulties in implementing True Moving Bed processes. Technological contributions come from adsorbent materials and rotary valve to simulate the solid movement. SMB is now a key technology for chiral separations. Modelling/Simulation tools provide sound basis for design/operation by using the concept of "separation volume". The third example is from the area of multifunctional reactors. The SMB technology is extended to the simultaneous reaction/separation.

During the last decade, a major shift has begun in chemical industry, since there is an urgent need for new tools that are able to support the optimization of operating technologies. This trend is driven by the new tools of information technology. Approaches of this shift differ from company to company but one common feature is that communication between design, manufacturing, marketing and management is centered on modeling and simulation, which integrates not only the whole product and process development chains, but all the process units, plants, and subdivisions of the company. These approaches are under continuous development. Among the wide range of possible improvements, this paper focuses to two frequent imperfections: (i) developed and refined process models are used only in advanced process control system (APC) integrated into distributed control system (DCS) and operator training systems (OTS), and not for detailed analysis and optimization, and (ii) optimal process operating points of these chemical plants are adjusted only at the design and test phase of a new technology, but optima moves with time, new catalyst system, lower price of reactants, claim for new or higher purity products, etc. The aim of this paper is to review, how to manage process optimization, and to show our process simulator based on the chemical engineering model of the technology. This paper will present a case study to demonstrate the technological and ecological benefits of the analysis and optimization of an B. Balasko et al. operating multi-product polymerization plant. The models of advanced process control system (APC) and reactor cascade were implemented in MATLAB ® Simulink ® environment, as a powerful and popular dynamic simulator.
