Design process conceptualization

The flowsheet synthesis of continuous chemical-like process can be performed following a systematic strategy known as the hierarchical approach. The procedure, initially proposed by Jim Douglas and coworkers in the decade 1980-90 [1, 2], describes the conceptual design process as a logical sequence of analysis and synthesis steps grouped in levels. Each level involves a flowsheet development mechanism based on design decisions. The result is not a unique solution but a collection of alternative flowsheets from which an evaluation procedure eliminates the less attractive ones. [Pg.21]

The current Work Process module of the Process Ontology abstracts from the characteristics of special types of work processes and provides a set of basic elements for modeling a wide range of processes. The Chemical Engineering Work Processes module imports both the Work Process module and the OntoCAPE product data model, and thus it provides the concepts required for modeling conceptual design processes in chemical engineering and their products (cf. Subsect. 2.6.2). [Pg.661]

The key to effective conceptual design, process improvement, and troubleshooting is the thinking process and how we use our basic knowledge. The process and procedure to solve any design, process improvement, or troubleshooting problems has six characteristics ... [Pg.1273]

We will discuss an evolutionary conceptual design process conducted for a specific engineering system for which we know dimensions, loads, location, and so on. It will be a process with n generations, that is, we will have a sequence of n-1 populations, excluding the initial or 0 population. We will also make an assumption that the size of all populations is the same and each has p individuals. [Pg.365]

The conceptual design process for a safety instrumented function begins with a Safety Requirements Specification (SRS). The SRS is an important document. It should contain complete specifications for designing all the safety instrumented functions. For each SIF the following information should be included ... [Pg.89]

After equipment is selected, the next step in the conceptual design process is the decision to use multiple instruments to serve the same purpose -redundancy. Redundancy is configured to provide continued system operation even though one or more specific instruments may fail - fault tolerance. Some redundant architectures provide fault tolerance against a... [Pg.94]

Scope and boundary For defining the scope and boundaries of FMEA/FMECA the major questions are Is it for conceptual, design, process, or software and services Also the purpose of the study shall be questioned. The scope of analysis shall take into account the physical boundaries, operating phases (operational or startup/shutdown phase, etc.), and any other assumptions considered in the referendum. In brief the following points shall constitute the scope and boundary of analysis. It is worth noting that all interface points should be included in the scope even if these are beyond the physical boundaries defined. [Pg.266]

The flowchart in Fig. 10.5 presents an idealized view of the conceptual design process. [Pg.161]

Thus, in the first step of the conceptual design process, the broad performance requirements were translated into a larger set of clearly defined functions along with the associated factors (Fig. 13.1). [Pg.229]

Turbine creep is considered one of more likely life limiting failure modes and should be continually studied through the conceptual design process. [Pg.339]

This system also offers automatic functions to assist the conceptual-design process. It automatically checks component interference and calculates the size of the model to further determine the size of the mold base (Figure 13). [Pg.1170]
