NAMP PIECE Introduction and Definition of Process Integration A brief history of Process Integration 1960’s-1970’s Linnhoff started the area of Pinch (bottleneck identification) at University of Manchester Institute of Science and Technology (UMIST), focusing on the area of Thermal Pinch. At about the same time, the UMIST Department of Process Integration was created, shortly after the consulting firm Linnhoff-March Inc. was formed 1980’s-1990’s Concept expansion from energy to process design 1990’s-2000’s Analogies used to derive Pinch concept from heat exchanger networks to mass transfer, water treatment and hydrogen systems PI is not really easy to define… Module 8 – Introduction to Process Integration 17
NAMP PIECE Introduction and Definition of Process Integration Modern Process Integration context 1. Process Integration might be regarded as a set of early stage process techniques for both new and retrofit design 2. Business objectives drive the development of PI: a) Emphasis is on retrofit projects in the “new economy” driven by Return on Capital Employed (ROCE) b) PI is finding value in data, especially as real time data systems have been implemented 3. Corporations wish to make more knowledgeable decisions: 1. For operations 2. During the design process 4. A strong trend today is to move away from unit operations and focus on phenomena. We no longer look at integration between units only, but also at integration within units (Process Integration Primer, IEA) Module 8 – Introduction to Process Integration 18
NAMP PIECE Introduction and Definition of Process Integration The International Energy Agency (IEA) definition of Process Integration (1993): “Systematic and general methods for designing integrated production systems, ranging from individual processes to total sites, with special emphasis on the efficient use of energy and reducing environmental effects” “Process Integration is the common term used for the application of methodologies developed for system-oriented and integrated approaches to industrial process plant design for both new and retrofit applications. ” “Such methodologies can be mathematical, thermodynamic and economic models, methods and techniques. Examples of these methods include: Artificial Intelligence, Hierarchical Analysis, Pinch Analysis and Mathematical Programming. Process Integration refers to optimal design; examples of aspects are: capital investment, energy efficiency, emissions, operability, flexibility, controllability, safety and yields. Process Integration also refers to some aspects of operation and maintenance” Sustainable Development Module 8 – Introduction to Process Integration 19
NAMP PIECE Introduction and Definition of Process Integration El-Halwagi, M. M. , Pollution Prevention through Process Integration: Systematic Design Tools. Academic Press, 1997. “A chemical process is an integrated system of interconnected units and streams, and it should be treated as such. Process Integration is a holistic approach to process design, retrofitting, and operation which emphasizes the unity of the process. In light of the strong interaction among process units, streams, and objectives, Process Integration offers a unique framework for fundamentally understanding the global insights of the process, methodically determining its attainable performance targets, and systematically making decisions leading to the realization of these targets. There are three key components in any comprehensive Process Integration methodology: synthesis, analysis, and optimization. ” Module 8 – Introduction to Process Integration 20
NAMP PIECE Introduction and Definition of Process Integration Nick Hallale, Aspentech – CEP July 2001 – Burning Bright Trends in Process Integration “Process Integration is more than just Pinch technology and Heat Exchanger Networks. Today, it has a far wider scope and touches every area of process design. Switched-on industries are making more money from their raw materials and capital assets while becoming cleaner and more sustainable” Module 8 – Introduction to Process Integration 21
NAMP PIECE Introduction and Definition of Process Integration North American Mobility Program in Higher Education (NAMP)-January 2003 “Process Integration (PI) is the synthesis of process control, process engineering and process modeling and simulation into tools that can deal with the large quantities of operating data now available from process information systems. It is an emerging area, which offers the promise of improved control and management of operating efficiencies, energy use, environmental impacts, capital effectiveness, process design, and operations management. ” Module 8 – Introduction to Process Integration 22
NAMP PIECE Introduction and Definition of Process Integration So What Happened? In addition to thermodynamics (the foundation of Pinch), other techniques are being drawn upon for holistic analysis, in particular: Process modeling Process statistics Process optimization Process economics Process control Process design Module 8 – Introduction to Process Integration 23
NAMP PIECE Introduction and Definition of Process Integration Here are some of the design activities that these techniques and methods address today: Process modeling and simulation, and validation of the results in order to have accurate and reliable process information for both new and retrofit design Minimize total annual cost by optimal trade-off between energy, equipment and raw material. Within this trade-off: minimize energy, improve raw material usage and minimize capital cost Increase production volume by debottlenecking Reduce operating problems by correct (rather than maximum) use of Process Integration Increase plant controllability and flexibility Minimize undesirable emissions and promote pollution prevention Add to the joint efforts in the process industries and society for a sustainable development Module 8 – Introduction to Process Integration 24

D, University of Wisconsin In the process industry, we find two levels of models: plant models, and models of unit operations such as reactors, columns, pumps, heat exchangers, tanks, etc. There are two types of simulation: steady-state and dynamic Module 8 – Introduction to Process Integration 33
NAMP PIECE Process simulation – Process modeling Process Modeling is an understanding of the phenomena of a given process and the transformation of this understanding into a model. What is a model used for? A model is an abstraction of a process operation used to build, change, improve, control, and answer questions about that process A model can be used for different basic problem formulations: simulation, identification, estimation and design A model can be used to solve problems in the areas of the process design, control and optimization, risk analysis, operator training, risk assessment, and software engineering for computer aided engineering environments Module 8 – Introduction to Process Integration 34

NAMP PIECE Pinch Analysis Module 8 – Introduction to Process Integration 40
NAMP PIECE Pinch Analysis What is Pinch Analysis? In the process industries, the prime objective of Pinch Analysis is to optimize the ways in which process utilities (particularly energy, mass, water, and hydrogen) are applied for a wide variety of purposes Pinch Analysis does this by creating an inventory of all producers and consumers of these utilities and then systematically designing an optimal scheme of utility exchange between these producers and consumers. Energy, mass, and water re-use are at the heart of Pinch Analysis activities With the application of Pinch Analysis, savings can be achieved in both capital investment and operating cost. Emissions can be minimized and throughput maximized Module 8 – Introduction to Process Integration 41
NAMP PIECE Pinch Analysis Features The basis of Pinch Analysis: The use of thermodynamic principles (first and second law) The use of design and economy heuristics Pinch Analysis is a technique to design: Heat Exchanger Networks (HEN) & Mass Exchange Networks (MEN) Utility Networks Pinch Analysis makes extensive use of various graphical representations In Pinch Analysis, the engineer controls the design procedure (interactive method) Pinch Analysis integrates economic parameters Module 8 – Introduction to Process Integration 42
NAMP PIECE Pinch Analysis Possible Benefits In addition, Pinch Analysis allows you to One of the main advantages of Pinch Analysis over conventional design methods is the ability to set a target energy consumption for an individual process or for an entire production site before designing the processes Pinch Analysis quickly identifies where energy, water, hydrogen and other material savings are likely to be found Reduction of emissions Pinch Analysis enables the engineer to find the best way to change a process, if the process allows it Update or develop process flow diagrams Identify process bottlenecks Run both departmental and full plant facilities simulations Determine minimal heating (steam) and cooling requirements Identify cogeneration opportunities Estimate costs of projects to achieve energy savings Evaluate new equipment configurations for the most economical installation Substitute past energy studies with a live study that can be easily updated using simulation Next Tool Module 8 – Introduction to Process Integration 43
NAMP PIECE Optimization by Mathematical Programming Module 8 – Introduction to Process Integration 44
NAMP PIECE Optimization of Mathematical Programming Mathematical Model A Mathematical Model of a system is a set of mathematical relationships (e. g. , equalities, inequalities, logical conditions) which represents an abstraction of the real world system under consideration A Mathematical Model can be developed using: Fundamental approaches Empirical methods Methods based on analogy A Mathematical Model of a system consists of four key elements: Variables Parameters Constraints Mathematical relations Module 8 – Introduction to Process Integration 45
NAMP PIECE Optimization of Mathematical Programming What is Optimization? An optimization problem is a mathematical model which in addition to the key elements stated in the previous slide contains one or more performance criteria The performance criteria are represented by an objective function. This function can be the minimization of costs, the maximization of profit or yield of a process, for example If we have multiple performance criteria, the problem is then classified as a multi-objective optimization problem There are different classes of optimization problems: linear and non-linear programming, LP and NLP, mixed-integer linear programming (MILP) and mixed-integer non-linear programming (MINLP) Whenever possible, linear programs (LP or MILP) are used because they guarantee global solutions. MINLP problems also feature many applications in engineering. Module 8 – Introduction to Process Integration 46

NAMP PIECE Stochastic Search Methods Module 8 – Introduction to Process Integration 48
NAMP PIECE Stochastic Search Methods Why Stochastic Search Methods? All of the model formulations that you have encountered thus far in the Optimization section have assumed that the data for the given problem are known accurately. However, for many actual problems, the problem data cannot be known accurately for a variety of reasons. The first reason is due to simple measurement error. The second and more fundamental reason is that some data represent information about the future (e. g. , product demand or price for a future time period) and simply cannot be known with certainty. Module 8 – Introduction to Process Integration 49
NAMP PIECE Stochastic Search Methods There are different types of stochastic algorithms Simulated Annealing (SA) Genetic Algorithms (GAs) Tabu Search These algorithms are suitable for problems that deal with uncertainty. These computer algorithms or procedure models do not guarantee global optima but are successful and widely known to come very close to the global optimal solution. SA takes one solution and efficiently moves it around in the search space, avoiding local optima GAs have the capability of collectively searching for multiple optimal solutions for the same optimal cost Tabu Search is an iterative procedure that explores the search space of all feasible solutions by a sequence of moves Next Tool Module 8 – Introduction to Process Integration 50

NAMP PIECE Data-Driven Process Modeling Module 8 – Introduction to Process Integration 55
NAMP PIECE Data-Driven Process Modeling Process Integration challenge Make sense of masses of data Necessity to work on bigger samples if full advantage is to be taken of all accessible information Drowning in data! Data-Rich but Knowledge-Poor Interesting, useful patterns and relationships not intuitively obvious lie hidden inside enormous, unwieldy databases. Also, many variables are correlated Data mining techniques: Neural Networks, Multiple Regression, Decision Trees, Genetic Algorithms, Clustering, MVA, etc. Module 8 – Introduction to Process Integration 56
NAMP PIECE Data-Driven Process Modeling Theoretical vs. Empirical Model Theoretical model uses First Principles to mimic the inner workings of a process Empirical model uses the plant process data directly to establish mathematical correlations Unlike theoretical models, empirical models do NOT take the process fundamentals into account. They only use pure mathematical and statistical techniques. Multivariate Analysis (MVA) is one such method, because it reveals patterns and correlations between variables independently of any preconceived notions Module 8 – Introduction to Process Integration 57
NAMP PIECE Data-Driven Process Modeling What is MVA?
