Typical Definition Phase (FEL-3) Deliverables These are listed below. In this phase, emphasis is typically on optimizing the best flow scheme and support systems combination. This optimum includes consideration of the plot plan and equipment arrangements for the entire facility. Process optimization cannot be done in isolation. Significant and continuous interaction with operations, maintenance, and construction... 

Definitive estimates. Definitive cost estimates are the most time-consuming and difficult to prepare, but they are also the most accurate. These estimates require preparation of plot plans, detailed flow sheets, and preliminary construction drawings. Scale models are sometimes used. All material and equipment is listed and priced. The number of labor hours for each construction activity is estimated. Indirect field costs, such as crane rentals, costs of tools, and supervision, are also estimated. This type of estimate usually results in an accuracy of 5%. 

Definitive and/or appropriation type estimates can be developed in four or six hours with the information normally provided in a Phase 1 package, i.e., P ID s, equipment list, plot plans, arrangement drawings, and single line electrical diagram. 

This chapter presents several plots of correlations between key metrics parameters for the 1050 plans docnmented in the extensive synthesis database. Each trend is discnssed in the context of achieving optimum and green syntheses. Examples of synthesis plans that achieve some measure of greenness are highlighted. The reader is referred to Chapters 5 and 6 regarding the definitions of metrics parameters. 

Medium-sized plants, according to the definition given in the introduction, are usually erected on an undeveloped plot of land on the existing premises of the company. This facilitates a lot of things, since for so-called greenfield mills , i.e. plants planned in the open countryside, a location itself has first to be found. In this case, the following questions have to be answered ...
