  • A real-life example of choosing an inherently safer process option
    Process Safety Progress, 2006
    Co-Authors: Karen A. Study
    Abstract:

    Although choosing an inherently safer alternative may seem straightforward, sometimes what seems to be the most obvious alternative may not provide the best risk reduction. The process Designer must maintain a broad perspective to be able to recognize all potential hazards when evaluating Design options. All aspects of operation such as start-up, shutdown, utility failure, as well as normal operation should be considered. Choosing the inherently safer option is best accomplished early in the option selection Phase of a project. However, recycle back to the option selection Phase may be needed if an option is not thoroughly evaluated early in the process. This report reviews a project to supply ammonia to a catalytic reactor. During the course of the project, an "inherently safer" alternative was selected and later discarded because of issues uncovered during the Detail Design Phase. The final option chosen will be compared to (1) the original Design and (2) the initial "inherently safer" alternative. The final option was inherently safer than both the original Design and the initial "inherently safer" alternative, even though the Design team initially believed that it would not be.

The process Designer must maintain a broad perspective to be able to recognize all potential hazards when evaluating Design options. All aspects of operation such as start-up, shut-down, utility failure, as well as normal operation should be considered. Choosing the inherently safer option is best accomplished early in the option selection Phase of a project; however, recycle back to the option selection Phase may be needed if an option is not thoroughly evaluated early in the process. In this paper, a project to supply ammonia to a catalytic reactor will be reviewed.

  • In Search of an Inherently Safer Process Option
    2005
    Co-Authors: Karen A. Study
    Abstract:

    While choosing an inherently safer alternative may seem straightforward, sometimes what seems to be the most obvious alternative may not provide the best risk reduction. The process Designer must maintain a broad perspective to be able to recognize all potential hazards when evaluating Design options. All aspects of operation such as start-up, shut-down, utility failure as well as normal operation should be considered. This is best accomplished early in the option selection Phase of a project. However, recycle back to the option selection Phase may be needed if an option isn’t thoroughly evaluated early in the process. In this paper, a project to supply ammonia to a catalytic reactor will be reviewed. During the course of the project, an “inherently safer” alternative was selected and later discarded due to issues uncovered during the Detail Design Phase. The best option will be compared to 1) the original Design and 2) the first “inherently safer” alternative. The best option was inherently safer than the original Design, but on the surface appeared less safe than the originally-selected "inherently safer" option.

  • Implementing an Electrical Network Monitoring and Control System on a Grassroots Refinery Project—Part I
    IEEE Transactions on Industry Applications, 2012
    Co-Authors: Ashish Deshmukh, Donald Dunn, Kenneth Mcalister, Keith Mccarthy
    Abstract:

    This paper shares the authors' experiences with implementing an electrical network monitoring and control system (ENMCS) on a grassroots 400 000 barrels per day refinery project with approximately 250 MW of peak load. The scope of the ENMCS spans from the 380-kV primary substation to the 480-V switchgear. The project is expected to proceed into the Detail Design Phase this year. This is a two-part paper. Part I will discuss the primary objectives of the ENMCS and the intended benefits to the refinery. The technical bases considered for the selection of the ENMCS architecture and protocol will be presented along with the historical background. Engineering management aspects of ENMCS implementation will be discussed. This paper is expected to be of interest to many within the petrochemical community as it is one of the first implementations of IEC 61850, Communication Networks and Systems for Power Utility Automation, on such a large grassroots scale. The intent is to publish Part II after the ENMCS is commissioned and present the lessons learned and the suggested improvements.

  • Development of a Concealed Power and Signal Transfer System for Sliding Doors
    2019
    Co-Authors: Max Koskinen, Jakob Alvelid
    Abstract:

    This master’s thesis report describes the product development process of a durable and concealed product for transferring power and signals to the moving door leafs of sliding doors. The thesis has been conducted in collaboration with Assa Abloy Entrance Systems, with the goal of enabling the use of accessories such as privacy e-glass, screens integrated in the glass, electric locks and sensors mounted on the door leafs for their sliding doors. To better understand Assa Abloy’s product portfolio as well as restrictions of different solutions to this problem, an extensive background research was conducted. This background research laid the groundwork for a concept generation where 28 concepts using many different technologies for power and signal transfer was generated. The concept ultimately chosen for further development consists of a spiral cable mounted on a support wire, installed completely concealed in the header profile of a sliding door. A prototype of the concept was subject to a life cycle test, confirming the feasibility of the concept, before a Detail Design Phase was initiated. During this Phase, focus was put into developing the concept with regards to manufacturability. Tools such as CAD-modelling, 3D-printing and sheet metal manufacturing enabled a rapid iteration of prototypes. The final Design consists of a spiral cable with a durable cable jacket, a support wire that enables easy installation, an injection molded bracket securing spiral cables of different dimensions with minimal cable wear to the door leaf as well as a sheet metal bracket that enables mounting of the support wire in the header profile. This product proved to be an easy to install, low cost and durable solution for transferring power and signals to the door leafs of sliding doors.

  • The function's definition and corresponding division for product Design process on ontology domain
    Journal of Engineering Design, 2011
    Co-Authors: Sun Zhi-hong
    Abstract:

    Product Design process is one of the important parts in product lifecycle.The quality of final product and manufacturing cost are usually decided by result of product Design process.The essence of product Design process is solution of product Design problem.It is also a decision making process,the subject on the uncertain condition,in order to fulfil the requirement of customer or subjects.The function is the key factor and content which decides this process.The function is core content.Around it,firstly,the current research on function in product Design process was analyzed.The advantages disadvantages of those pasted research were listed.Then,based on the concept of ontology,and the common between function and ontology,the function definition was proposed oriented to product Design process.The relationship among function,requirement and requirement function was presented.Furthermore,comparing with traditional view,a new division of product Design process was proposed,in which,the product Design process was divided into two Phases: the qualitative conceptual Design Phase and the quantitative Detail Design Phase on the basis of function's mainline in product Design product.At last,the outline of this paper was summarized,and the future work of this paper was pointed out.
