The Future

In today's economy, chemical engineering must respond to the changing needs of the chemical process industry in order to meet market demands. The evolution of chemical engineering is necessary to remain competitive in global trade. The ability of chemical engineering to cope with managing complex systems met in scientific and technological problems is addressed in this paper. Chemical Engineering is vital for sustainability: to satisfy both the market requirements for specific end-use properties of products and the social and environmental constraints of industrial-scale processes. An integrated system approach of complex multidisciplinary, non-linear non-equilibrium processes and phenomena occurring on different length and time scales is required. This will be obtained due to breakthroughs in molecular modeling, scientific instrumentation and related signal processing and powerful computational tools. The future of chemical engineering can be summarized by four main objectives: (1) Increase productivity and selectivity through intensification of intelligent operations and a multiscale approach to processes control; (2) Design novel equipment based on scientific principles and new production methods: process intensification using multifunctional reactors and microengineering and microtechnology (3) Extend chemical engineering methodology to product design and engineering using the "triplet 3PE molecular Processes-Product-Process Engineering" approach; (4) Implement multiscale application of computational chemical engineering modeling and simulation to real-life situations from the molecular scale to the production scale.

Production Objectives

Process intensification (PI) is currently one of the most significant trends in chemical engineering and process technology. PI is a strategy of making dramatic reductions in the size of unit operations within chemical plants, in order to achieve production objectives. PI technology is able to change dramatically the whole chemical engineering industry pathway to a faster, cleaner and safer industry. Nonetheless, PI technology will be handicapped if such system is not properly controlled. There are some foreseeable problems in order to control such processes for instance, dynamic interaction between components that make up a control loop, response time of the instrumentations, availability of proper sensor and etc. This paper offers an overview and discussion on identifying potential problems of controlling intensified systems.

Use Efficiency

Abstract Minimization of the costs with simultaneous increase in the raw materials and energy use efficiency is a challenge for the modern world. One of the most effective tools to solve this task is the use of process intensification (PI), first proposed by Ramshaw C. The incentive for process intensification, Proceedings, 1st Intl. Conf. Proc. Intensif. for Chem. Ind., 18, BHR Group, London, 1995, p. 1. and then extended by Stankiewicz AI, Moulijn JA. Process intensification: transforming chemical engineering. Chem Eng Prog 2000: 22–34. In the presented review, some principles of PI in chemical engineering and their application for wide variety of processes is discussed. The role of the Russian scientist with a research background is carried out in other countries.

Swirled Flows

AbstractExploration of confined swirled flows in the former USSR and present-day Russia has a long history and is presented by numerous publications, mostly written in Russian. The obtained results have been put to practical use in different areas of chemical, energy, and processing industries. In view of the process intensification concept, such characteristics of confined swirled flows may be considered unique: high centrifugal gravity, elongation of trajectories, the presence of internal separation zones, energy separation phenomena, and efficient mass/heat transfer in the absence of any moving parts. For instance, high gravity provides an excellent opportunity for multiphase flow stabilization, preventing the appearance of nonuniformities and stability loss, while enhancement of various driving forces acting on the reaction medium takes place. This review is devoted to outlining the main research trends and to discuss the most essential practical implementations in the subject matter done up until now. It is not foreseen to embrace the whole area of swirled flow investigations in the world, but only covers most of the significant ideas and applications contributed in by former Soviet and Russian scientists and engineers. Shortcomings and difficulties of using swirled flows are also briefly discussed.

Proper Design

Process intensification is the term which describes an innovative design approach in chemical engineering aiming on a significant increase of the specific performance of chemical reactors and plants miniaturization, of at least an order of magnitude. In addition, the running costs should be reduced and the process should be more efficient, safer, and less polluting than the existing ones. Micro process technology is considered as means of process intensification leading to better use of raw materials and energy. Chemical micro-structured reactors (MSR) are devices containing open paths for fluids with dimensions in the sub-millimeter range. Mostly they consist of multiple parallel channels with diameters between ten and several hundred micrometers where the chemical transformations occur. This results in a high specific surface area in the range of 10,000 to 50,000 m2m−3 and allows a more efficient mass and heat transfer compared to traditional chemical reactors having usually ∼100 m2m−3. Another important feature of micro-structured reactors is that the heat exchange and the reaction are mostly performed in the same gadget. Intensification of heterogeneous catalytic processes involves besides of innovative engineering of micro-structured reactors, the proper design of the catalyst. This requires the simultaneous development of the catalyst and the reactor. The catalyst design should be closely integrated with the reactor design taking into consideration the reaction mechanism, mass/heat transfer and the energy supply / evacuation resulting in high selectivity and yield of the target products. Besides general criteria for the choice and proper design of micro-structured reactors for process intensification, particular needs for homogeneous and multiphase reactions will be discussed.
