Latest News - "MT"
If you still think that "MT" is only used to label compressed gas cylinders, then read on... The National Institute of Standards and Technology (NIST) announced results of its tests of several machine translation (MT) systems recently. The agency gave the top ranking to Google, not to university research programs or the standard Internet tool from Systran. Google used statistical analysis of word patterns to beat the traditional method of rule-based systems. To see why this is so important to the global chemical industry, take a look at the table in the news article.

Virtual Library on Process Systems Engineering from PASI Conference
The Pan American Advanced Studies Institute (PASI) on Process Systems Engineering took place on August 16-25, 2005, Iguazu Falls. The specific site for the workshop was the Hotel Cataratas in the Parque Nacional Iguazú, Argentina. The goal of the PASI on Process Systems Engineering, which was organized by Ignacio Grossmann, Jaime Cerdá and Jose Pinto, was to provide an advanced workshop that would bring together faculty and Ph.D. students from various countries in the Americas (U.S., Canada, Mexico, Argentina, Brazil, Chile, Colombia and Venezuela). Several students from Spain also participated. This workshop was also part of the activities of the CEPAC (Chemical Engineering Pan American Collaboration) group.
There were a total of 69 participants, and 21 lecturers and seminar speakers. The U.S. representation consisted of 25 Ph.D. students belonging to 21 universities: Auburn, Austin, Carnegie Mellon, Delaware, Florida, Georgia Tech, Illinois-Chicago, Illinois-Urbana, Lamar, Lehigh, Maryland, Northwestern, U. Pittsburgh, U. Pennsylvania, Penn State, Polytechnic, Princeton, Purdue, Rutgers, Texas A&M, Wisconsin (see list of participants). Funding was provided by the National Science Foundation and the Department of Energy. Matching funds were obtained from the Agencia Nacional de Promoción Científica y Tecnológica from Argentina, Carnegie Mellon University, Petrobras, Bayer and Honeywell (see sponsors)
A major objective of the PASI on Process Systems Engineering was to expose to the participants state-of-the-art developments in Process Systems Engineering in the following areas:
There were a total of 12 modules in these areas, and each module was covered through a lecture lasting between 3 to 6 hours. There were also a number of one-hour seminars that complemented the lectures. A major outcome of the PASI conference was the development of virtual library on Process Systems Engineering that consists of the Powerpoint slides of the presentations, background articles, as well as exercises and MATLAB and GAMS computer files for various applications. The virtual library, found at http://cepac.cheme.cmu.edu/pasilectures.htm, contains the following topics:
Part 1. Optimization Modules
Part 2. Process and
Product Design Modules
Members of the CAST Division should hopefully find the material in this virtual library to be helpful. Practitioners will find useful overviews of areas that are of current interest and that are not normally found in textbooks and reference texts. The overviews emphasize the state-of-the-art in the corresponding area and are complemented by exercises. Academics should find the library useful for graduate level courses in Process Systems Engineering, and for introducing their students in the various research topics, as well as exposing them to various case studies. We intend to periodically update the presentations, and we will appreciate your feedback or comments.
Finally, we should conclude from our experience in this conference it was evident that Process Systems Engineering (PSE) is still very much an active and vibrant area of research in Chemical Engineering. Furthermore, it is clear that PSE continues to be of great industrial relevance as the scope of applications continues to grow, ranging from the molecular biological systems to specialty and large-scale commodity chemical plants, and all the way to the enterprise level. Our hope is that the virtual library will help to promote the interest in Process Systems Engineering.
2005 CAST Award Winners
by Karen High, 2005 CAST Second Vice-Chair
We would like to congratulate the CAST Award winners for 2005. These awards were presented during the CAST Dinner at the 2005 AIChE Annual Meeting in Cincinatti, OH, in November. This announcement includes short biographies and some notable quotations from the supporting letters.
Computing in Chemical Engineering Award: Frank Doyle, UC, Santa Barbara
For establishing process control principles in the field of systems biology, including control of complex biomedical systems, and analysis of regulation in biophysical networks. Sponsored by The Dow Chemical Company.
Dr. Frank Doyle holds the Duncan and Suzanne Mellichamp Chair in Process Control in the Department of Chemical Engineering at the University of California at Santa Barbara, as well as appointments in the Electrical Engineering Department, and the Biomolecular Science and Engineering Program. At UCSB, he is the Associate Director of the $50M Institute for Collaborative Biotechnology funded by the Army Research Office. Prior to his appointment at UCSB, he has held faculty appointments at Purdue University and the University of Delaware, and held visiting positions at DuPont, Weyerhaeuser, and Stuttgart University. His research interests are in systems biology, drug delivery for diabetes, and control of particulate processes.
“Frank’s research on the reverse engineering of biological systems was innovative, high risk (very laudable for a young person at the start of his career!) and flashy…at UCSB Fran’s career has taken a new turn…and he has been doing research at the forefront of systems biology.”
“Frank has established himself as the leading academic researcher in his age group in the area of biological process modeling and control, which arose out of a very productive collaboration with Dupont and other health-related companies.”
“Frank’s papers on control of glucose levels in the bloodstream by means of dynamic insulin delivery are first-rate, and the principles they elucidate and espouse could provide very helpful enhancements of drug delivery technology…”
“He contributed both to the model development for regulatory mechanisms, which must be seen as the enabling basis for all system theoretic work in this area, as well as to the development of system theoretic methods to analyze those systems.”
Computing Practice Award, Mike Morshedi, PAS, Inc.
For contributions of fundamental technology and industrial-quality software for modeling, control, and optimization and for the development of QDMC for constrained Model Predictive Control. Sponsored by Aspen Technology, Inc. and ExxonMobil Chemical Company..
With over thirty years of experience in the development and application of on-line optimization and control technologies, Dr. Mike Morshedi is one of the preeminent thought leaders and mathematical experts in the advanced process control industries worldwide. In 1980, Dr. Morshedi joined Shell Development Company where he became one of the principal developers of both OPERA and QDMC – industry’s first equation-based optimizer and modern multivariable controller. As Chief Scientist at PAS, Dr. Morshedi leads a team of advanced application technologists focusing on soon-to-be-released next generation solutions that offer robust plant optimization and abnormal situation management concurrently.
“The impact of Mike’s work on industrial practice has been evident, with major applications of Mike’s software at many of the large oil refineries in the Houston area.”
“Mike was instrumental in introducing the concept, benefits and techniques of open equation modeling to AspenTech...Mike’s methods are used in virtually every real-time optimization application in operation today.”
“Mike’s early work with Shell Oil and resulting publications, has established him as one of the “founding fathers” of MVC…after Mike founded DOT-Products, Inc. he became the principle developer of a particularly novel formulation of MVC technology embodied in the STAAR Controller.”
Outstanding Young Researcher Award: Richard Braatz, UIUC
For theoretical results in robust control, and their successful implementation in the paper, pharmaceutical, and other industries to increase product quality, reduce pollution, and conserve energy.
Dr. Richard Braatz is Professor and University Scholar at the University of Illinois at Urbana-Champaign, where he holds joint positions in Chemical and Biomolecular Engineering, Mechanical and Industrial Engineering, Bioengineering, Applied Mathematics, Computational Science and Engineering, and the Beckman Institute for Advanced Science and Technology. Dr. Braatz is a co-author of 90+ journal papers and 3 books published by Springer Verlag including the textbook Fault Detection and Diagnosis in Industrial Systems. In recent years Dr. Braatz has been investigating multiscale systems engineering, which is the simultaneous design and control of processes from molecular to macroscopic length scales.
“In the area of sheet forming processes, Prof. Braatz has pioneered new approaches for the control and identification…the second application is in the control of crystallization and particulate process applications.”
“…he initiated new programs in the control of sheet and film processes, and in pharmaceutical crystallization. He has had a huge impact on both of these fields and continues to do so.”
“Richard is by far the most cited process control researcher of his generation – and many of these citations come from outside chemical engineering.”
“Richard’s contributions in the general area of Control and Process Systems Analysis and in the particular area of “Robust control of complex, large scale systems” are truly deep and broad; the practical implications are also very significant indeed.”
“Richard has addressed a series of real-world process control problems in ways that need to be highlighted for their inherent value. I am referring to his papers on the modeling, analysis and control of sheet and film processes (e.g. paper coating, polymer film extrusion) and batch crystallization.”
W. David Smith, Jr. Graduate Student Publication Award: Martha Gallivan, Georgia Tech
For the journal paper, ‘Reduction and Identification Methods for Markovian Control Systems, with Application to Thin Film Deposition,’ with Richard M. Murray, International Journal of Robust and Nonlinear Control, 14, 113-132 (2004). Sponsored by E.I. du Pont de Nemours and Company.
Dr. Martha Gallivan is an assistant professor in the School of Chemical & Biomolecular Engineering at Georgia Tech. Her graduate research was on the control of thin film deposition under the direction of Professors Richard Murray, David Goodwin, and Harry Atwater, and was supported by an NSF Graduate Fellowship. Professor Gallivan was the recipient of an NSF CAREER award in 2004, which supports computational and experimental research in chemical vapor deposition of metal oxide films for control of film microstructure. Her overall research program is on optimization and control of molecular-scale structure using self assembly with applications in inorganic crystalline films, polymer structure, and nanowire assembly.
“This is an important paper at the interface between atomistic/stochastic simulation and macroscopic systems theory and control.”
“What distinguishes this specific paper, aside from the high dimensionality of the model, is the treatment of the inherent stochasticity arising in microscopic-level models.”
“My assessment of the paper’s contributions is based on the innovative approach proposed in the paper for the simulation and model reduction of multiscale systems that are suitable for real time dynamic control and optimization.”
“Martha’s work is a landmark paper, one of the very first papers that successfully combines Kinetic Monte Carlo simulation with macroscopic control in a convincing manner.”

In this application, a Fourier Transform Near InfraRed Analyzer (FT-NIR) is used to predict properties in Gasoline (Motor Spirit or MS). The predicted properties are given as a feedback to Advanced Process Control Software as Blend Property Control (BPC). The FT-NIR together with BPC and BRC (Blend Ratio Control) optimizes blending in the gasoline pool so that target values in final properties are achieved with minimum reblend and product giveaways.
Analysis is made on the basis of key structural characteristics in PIONA classification and its impact on property values.
In this study the key link between regression coefficients and structural characteristics of hydrocarbons is highlighted. The regression coefficients play a major role in prediction accuracy of the regression model developed. The step changes of the coefficients in terms of process recipe changes and process operating variable changes are highlighted.
The entire paper [147 KB] may be downloaded in pdf format. This paper uses Chemometrics and PLS techniques for data modeling. In an additional presentation [398 KB], PCA techniques for reducing error in the model are explained. Also, an overall tutorial on Chemometrics is in this presentation [460 KB].

Quote of the Day
"I once read a silly fairy tale, called The Three Princes of Serendip: as their Highnesses travelled, they were always making discoveries, by accidents and sagacity, of things which they were not in quest of: for instance, one of them discovered that a mule blind of the right eye had travelled the same road lately, because the grass was eaten only on the left side, where it was worse than on the right—now do you understand Serendipity?"
