Sustainable CAPE-education and careers for chemical engineers
Bart Drinkenburg Technische Universiteit Eindhoven, DSM Research, Geleen, The Netherlands
Abstract
Chemical engineering education is in need to include new elements. Business of the Process Industry in the developed world is shifting from specification to performance products. More attention is then required for product technology and product development.
Students are given tools for technology build-up, but not for technology handling. Therefore a good basis in technology management is also essential in the chemical engineering study.
CAPE has organically grown to be very important part in design and operation and should also be given a fair share in the programme. This all means that choices have to be made and that at least a specialized MSc in chemical product/process engineering is necessary. Such a clear cut choice might well attract more students.
In industrial practice CAPE steadily gains more importance, not only as a tool but also because plants are increasingly dependant upon CAPE and control. A CAPE background, as well as such in Process Control will in the future be very valid, perhaps even necessary, for eg. plant management jobs.
1 Introduction
It has always been point of discussion whether education, or schooling, has to follow societal demand or that society can pick its choice from whatever is offered and has to take on further schooling within the individual companies and institutes. The question arises most often within universities where the concept of academic proliferation is a hot issue in words, but seldom in contents. In our chemical world such has led to a basic structure where in the first part of the study emphasis is laid on acquiring tools and in the later part (M.Sc. and Ph.D) research is a prominent part.
In many universities, especially in Germany and the Netherlands, it has even gone so far that the M.Sc. part is merely seen as the introductory phase to do a Ph.D.
Now all over Europe the position has to be reconsidered due to the Bologna agreement and because of major changes that develop in the process industry.
I will limit myself to the chemical engineering education and mirror that to the work chemical engineers have to do within their jobs once they have left university. The latter will already tell that I see university as professional schooling and I immediately follow up this statement that this is not in contradiction with the academic stature. Or, to make it simple: an academic study not only has to follow society, industry being part of it, it has also to anticipate on changes that are likely to occur in that society.
To be more explicit: academic level has to do with analyzing complex problems and, if possible, finding solutions. Especially the first part, analyzing complex problems, is important. What is the context of the problem, how is fact-finding to be organized. Only then possible directions to solutions can be found and ranked, only then good work can be done.
Especially engineers, educated in terms of tools, experience great troubles with the analysis part. They are schooled in problems with two or three parameters that deliver answers in three decimals accuracy. But then, in practice, they are confronted with many context parameters that only can be weighted and no arithmetics are available.
It will much improve the level of creativity of our students if we introduce such problems early in the engineering studies, at the time the students are most sensitive to it!
2 Nowadays chemical engineering education
Chemical engineering has become a discipline in the twentieth century, not the least because it was largely stimulated in university by financial contributions from industrial companies. It has developed along a few lines, called by James Wei (1) paradigms. The first was the paradigm, I prefer concept, of unit operations. Unit operations like distillation, extraction, sorption, not only provided a generalized method for separation processes. Also, and more important, unit operations established firmly countercurrent processes as an effective and efficient method. Moreover, since it showed that many different types of industrial activity indeed had a common methodological background, it laid the foundation of the concept Process Industry.
In the fifties the work of Bird, Stewart and Lightfoot (2) digged deeper and the concept of physical transport phenomena was introduced, not only important for what was called during that time “physical technology” but even more for reactor calculations and reactor development. Process Integration then followed together with the extremely rapid introduction and development of Process Control, once we got rid of pneumatic control through the powerful introduction of process computers and electronic control from the seventies on. Table 1 provides the layered build-up of the chemical engineering discipline as it stands now on a strong basis of first principles.
Table 1
Build up of the discipline
5. Manufacturing and technology management
4. Process integration
3. Equipment modeling
2. Kinetics
1. Thermodynamics
0. Basic chemistry, physics, biology, mathematics, economy
Building on knowledge in basic sciences like chemistry, physics, etc. a first layer of thermodynamics is present, often considered to be part of layer zero, but more often than not to be redone in chemical engineering education because of two reasons: firstly because students are unacquainted with how to apply thermodynamics in practical situations like phase equilibria and flow-through systems, secondly because they have gathered the impression that thermodynamics forbid to break through equilibria while the essential work of chemical engineers is just doing that to complete conversions and separations. Nevertheless, thermodynamics supply essential data, eg. physical and chemical equilibria.
Layer 2, kinetics be it in reactions kinetics or in transport phenomena describes the basic mechanisms and through this alone already provides an rough impression of the size of the equipment needed. Thinking in time constants is a difficult but essential part to teach here, since it provides a background for process dynamics.
Layer 3, modeling, precizes the equipment in terms of design variables, both for reactors, separation equipment and some auxiliary equipment.
In the layer process integration the process layout, HES, flow sheeting, instrumentation, process dynamics, process control, logistics and many details are worked out, including start up and shut down. CAPE is extremely useful in this part.
The layer manufacturing and technology management is almost non-existent in chemical engineering as a discipline and a serious lack in the education.
Now, of course, this layered model is not representative for the way chemical engineering is applied in practice, which is problem-oriented. Then the starting point will be, especially in Research and Development, process synthesis, providing rough alternatives for process lay-out, followed by onion-skin procedures as reactor configuration, separation processes, logistics, heat/energy integration, process control. There is an inherent danger in this approach, upon I will come back later.
In general terms it can be said that the methodology and the tools are very connected to practice in the petrochemical industry, not surprising given the gigantic growth of the industry in the time period that chemical engineering developed into a discipline.
3 What is going on in the process industry?
The process industry, as said, showed a very rapid expansion after world war II, both in production volumes and in scale of the plants. Environmental problems, including safety, extended from local impact to regional and later even to global issues. Consequently great efforts and investments were done in waste abatements, energy efficiency and process mastering and control. Modeling and subsequently CAPE have played and play a very important, not to say a dominant, role in making the process industry an example of good manufacturing practice, especially in the base chemical industry.
But in the mean time there are also considerable shifts in the industry itself.
Reorientation cause major mergers in the base chemical and material industry, often called the commodity industry, leading to potential cost reductions in the business environment as marketing and sales, business development and research and development.
It means less work for professionals but at a high level.
In contrast with this is the situation in the areas of life sciences/fine chemicals and performance materials. Here there is much to do. Large companies are shedding off their divisions, others reorientate on acquiring just these parts. Splitting occurs here as often as mergers. In a technological sense these companies are on the average working at a relatively low level of technology and this is very challenging.
It is questionable whether this work will be done in house or via outsourcing even to the point that research and development and possibly manufacturing will be outsourced. Behind this thinking are a number of reasons:
■ quality: in a modern company it is extremely difficult to keep up quality of the work in technological issues. Employees are expected, certainly at academic level, to broaden their view by job rotation. Youngsters enter the company, see the opportunities and after four years say goodbye to in particular Rand...
