Optimization-Based Approach for Process Plant Layout
Industrial & Engineering Chemistry Research, 2018Co-Authors: Jude O. Ejeh, Songsong Liu, Mazaher Molaei Chalchooghi, Lazaros G. PapageorgiouAbstract:This paper presents an optimization-based approach for the multifloor Process Plant layout problem. The multifloor Process Plant layout problem involves determining the most efficient—based on predefined criteria—spatial arrangement of a set of Process Plant equipment with associated connectivity. A number of cost and management/engineering drivers (e.g., connectivity, operations, land area, safety, construction, retrofit, maintenance, production organization) have been considered over the last two decades in order to achieve potential savings in the overall Plant design Process. This work constitutes an extension of the work by Patsiatzis and Papageorgiou [ Ind. Eng. Chem. Res. 2003, 42, 811−824;10.1021/ie020586t] to address the multifloor Process Plant layout problem. New features introduced modeled tall equipment with height greater than the typical floor height in chemical Process Plants, with connection points at a design-specified height for each piece of equipment. The number of floors, land area, ...

Safe Process Plant Layout using Mathematical Programming
Computer-aided chemical engineering, 2007Co-Authors: Dimitrios I. Patsiatzis, Lazaros G. PapageorgiouAbstract:This paper presents a general mathematical programming formulation, considering simultaneously Process Plant layout and safety. The proposed model determines the detailed Process Plant layout (coordinates and orientation of each equipment item), the number and type of protection devices in order to reduce possible accidents and the financial risk. The problem is formulated as a mixed integer non-linear programming (MINLP) model and its applicability is demonstrated by a literature example.

Chemical Engineering Research & Design, 2004Co-Authors: Dimitrios I. Patsiatzis, G. Knight, Lazaros G. PapageorgiouAbstract:This paper presents a general mathematical programming formulation considering simultaneously Process Plant layout and safety. The proposed model determines the detailed Process Plant layout (coordinates and orientation of each equipment item), the number and type of protection devices in order to reduce possible accidents and the financial risk utilizing the Dow Fire and Explosion Index system. The overall problem is formulated as a mixed integer linear programming (MILP) model and its applicability is demonstrated by an illustrative example.

optimization of Process Plant layout with pipe routing
Computers & Chemical Engineering, 2005Co-Authors: Reginaldo Guirardello, Ross E SwaneyAbstract:Abstract An optimization approach for the design of chemical Plant geometric layout is presented. The task is decomposed into a sequence of subproblems that are solved using mixed integer linear programming models. The 3D layout problem with noninterference constraints is computationally difficult, and simultaneous treatment for placement of equipment and routing of pipes for the number of components comprising a typical Plant is as yet impractical. In the approach presented, the optimization of the layout is computed first, and then is followed by the piping layout and routing. The models allow incorporation of practical design constraints. An example is presented that show the resulting design appear both reasonable and near-optimal. Different techniques are studied in order to do an automatic routing of a Process Plant layout. The procedure is based on a (partially arbitrary) selection of node positions where pipes can be routed, respecting restrictions of safety and minimum distances from components. These nodes are connected by arcs that avoid the physical space of components. The graph defined by the nodes and arcs are used to find the minimum cost for the pipes. Two methods may be used: a mixed integer linear program for the global minimization of the cost of all pipes, or a shortest path algorithm for the minimization of the cost of each pipe individually. The MILP approach can include capacity constraints, but it can be applied only for small problems. The shortest path approach is better for larger problems and can include pipes with branches and stress analysis.

Process Plant Layout Optimization: Equipment Allocation
Principles and Practice of Constraint Programming, 2018Co-Authors: Gleb Belov, Tobias Czauderna, Matthias Klapperstueck, Mitch Smith, Michael Wybrow, Ilankaikone Senthooran, Maria Garcia De La Banda, Mark WallaceAbstract:Designing the layout of a chemical Plant is a complex and important task. Its main objective is to find a most economical spatial arrangement of the equipment and associated pipes that satisfies construction, operation, maintenance and safety constraints. The problem is so complex it is still solved manually, taking multiple engineers many months (or even years) to complete. This paper provides (a) the most comprehensive model ever reported in the literature for spatially arranging the equipment, and (b) a Large Neighbourhood Search framework that enables complete solvers explore much larger neighbourhoods than previous approaches to this problem. The two contributions are part of a system being developed in collaboration with Woodside Energy Ltd. for arranging their Liquefied Natural Gas Plants. The results are indeed so promising that Woodside are actively exploring its commercialisation.

greenpro i a risk based life cycle assessment and decision making methodology for Process Plant design
Environmental Modelling and Software, 2002Co-Authors: Faisal Khan, Rehan Sadiq, Tahir HusainAbstract:In recent years, significant attention and emphasis has been given to cleaner and greener technologies in Processes and product manufacturing. This is recognized as a key element in pollution prevention (P2) and development of sustainable strategies. Life cycle assessment (LCA) is a systematic approach that enables implementation of cleaner and greener product and Process concepts in industry. In recent times substantial progress has been made in the use of LCA for product evaluation and selection. However, its use in cleaner and greener Process design and decision-making has not been explored to a great extent. Process design and decision-making are challenging activities that involve trade-off of conflicting objectives, namely costs, technical feasibility and environmental impacts. These conflicting objectives can be analysed at the early design and decision-making stage by considering the full life cycle of a Process or a product. A cleaner and greener Process is the one that is cost optimal, technically feasible, and environmentally benign. To obtain these results LCA requires various tools and techniques in a systematic methodology. This paper proposes a holistic and integrated methodology GreenPro-I for Process/product design by combining the traditional LCA approach with multi-criteria decision-making methods. This methodology is simple and applicable at the early design stage and is more robust against uncertainty in the data. Application of the methodology has been demonstrated in the paper through a urea production case study.

Chapter 13 – Pollution Control
Process Plant Layout, 2017Co-Authors: Sean MoranAbstract:Nowadays, the handling, treatment, and disposal of solid, liquid, and gaseous wastes, and the control of nuisances such as noise, odor, and other pollution is subject to stringent control in virtually all countries. Legislation on environmental, health, and safety issues has arguably had a far more profound effect on Process Plant design practice than the advances in technology in recent decades. This section has consequently been very much expanded from the first edition in order to reflect this.

Process Plant Design
An Applied Guide to Process and Plant Design, 2015Co-Authors: Sean MoranAbstract:Abstract Process Plant design involves making choices between a great many options in an uncertain environment in order to optimize cost, safety, and robustness. Professional design Processes are similar across disciplines, sectors, and worldwide, as a result of their evolution to fit the professional design environment. Academics have dreamt up many alternatives to them, but these captive-bred strains never survive in the wild.

How to Lay Out a Process Plant
An Applied Guide to Process and Plant Design, 2015Co-Authors: Sean MoranAbstract:Abstract Laying out a Process Plant on a site is a matter of balancing competing demands, many of which will differ from site to site. No other part of the Process Plant design exercise is more of an art than this. Safety, capital, and running cost, ease of maintenance and operation, and esthetics have to be balanced, as do the competing demands of other disciplines and the vagaries of the particular site. Drawings are the key to the exercise.

Process Plant design deliverables
An Applied Guide to Process and Plant Design, 2015Co-Authors: Sean MoranAbstract:Abstract The complete Plant is the ultimate deliverable, but the immediate deliverables for working engineers are the drawings, schedules, datasheets, and so on which explain exactly what the designer intends to be built. In addition to the deliverables which define the design, there are costings, programs, safety documentation, and so on. The documents which students are asked to produce in the academic setting rarely resemble realistic engineering deliverables, so the beginner designer often has a steep learning curve finding out how to produce deliverables which will be understood by others.

Design and layout of Process Plants
Engineering & Technology Reference, 2012Co-Authors: Sean MoranAbstract:This study offers a summary of the main consensus professional Process Plant layout methodology in sufficient detail for it to be used as a template for design activity. This study also deals briefly with the issue of how Process Plant layout methodology has changed in the last thirty years. It has in summary changed little, other than to the extent that it has been required to do so by tighter regulation of health, safety and environmental matters.
