Project definition

Cyclohexanone is a colorless high-boiler liquid with the normal boiling point at 156.7°C. Some quality specifications are given in the Table 5.1. 

For more generality, this case study will develop a process capable of producing cyclohexanone and cyclohexanol in any desired proportion. We will voluntarily

For example a process flow scheme for crude oil stabilisation might contain details of equipment, lines, valves, controls and mass and heat balance information where appropriate. This would be the typical level of detail used in the project definition and preliminary design phase described in Section 12.0. 

The accuracy of a fixed capital estimate tends to be a function of the design effort involved. As the project definition is refined, the estimates evolve from the various preliminary phases, ie, order of magnitude, predesign, factor estimates, etc, into the more detailed estimates used for budget authorization, project control, and contracts. At the same time, the uncertainty in the estimate decreases from 50% to as Htfle as 5%. 

Conduct a project definition study to discover which of the many possible solutions will be the most suitable. 

Conceptual Design Review - to establish that the design concept fulfills the requirements before project definition commences... 

When you are confident that you have a firm grasp of the situation, work up a preliminary project definition. This preliminary definition will be subject to revision as additional information and experience is acquired. 

Now, using this project definition, state the end-results objective of the project. 

Evaluation allows you to choose a course of action that will meet both your project definition and end-results objective. 

Report of the Project Definition Study on the Nitrogen Detector System, TRIUMF, Vancouver, BC, Canada, July 1992. 

In periods of high inflation, the results of various estimates and accuracy may overlap. At such times, four categories may be more suitable, namely, study, prehminary definitive, and detailed categories. At present, some conmanies employing the front-end loading (PEL) process for project definition and execution use three categories ... 

The size of capital project also has an influence on FEL outcome based on IPA statistics. IPAs data indicate that small projects benefit more from better project definition prior to the EPC phase than do major projects. The data also indicate that small projects typically have more late changes than do larger projects.

Section 1 - Project and Process. This starts with the project definition (objective, description, location, product and raw material specifications, quantity, quality, output requirements, throughput for equipment sizing purposes). Closely linked with this is a statement of the mode of operation (e.g. day time only or 24 hour operation, continuous or batch processing) and expected control philosophy (centralised computer or local, methods of data collection and storage, programmable controllers or hard-wired ). 

The Project Team Manager and members having been assigned to the project, their first task is to carry out a complete definition of the project. The team will know the overall goal of the project but its purpose and objectives will need to be clarified and redefined in more specific terms of defiverables, assumptions and constraints. Project definition enables all the stakeholders, both internal and external, to understand and agree upon the goals, responsibilities, assumptions and success criteria to be used. The planning of the project and the allocation of resources should only start once this has been done. 

Once the Project Definition stage is completed and accepted by DTI, the project moves into design and implementation phases. 

The goal of this project, which was started in 2003, is to develop the means for safe transport of the submarines to their dismantlement sites to avoid accidents such as the sinking of the K-159 which sank while under tow. During the project definition phase over 28 different options have been evaluated, this has now been reduced to 4 options.
