Capital cost estimates for chemical process plants are often based on an estimate of the purchase cost of the major equipment items required for the process, the other costs being estimated as factors of the equipment cost. The accuracy of this type of estimate will depend on what stage the design has reached at the time the estimate is made, and on the reliability of the data available on equipment costs. In the later stages of the project design, when detailed equipment specifications are available and firm quotations have been obtained, an accurate estimation of the capital cost of the project can be made. 

The DIPPR databases were developed in the United States by the Design Institute for Physical Properties of the American Institute of Chemical Engineers. The DIPPR projects are aimed at providing evaluated process design data for the design of chemical processes and equipment (www.aiche.org/dippr/projects.htm). The Project 801 has been made available to university departments see Rowley et al. (2004) and http.//dippr.byu. edu/description/htm. 

Project cost data were reported for 24 of the 138 SVE projects in the dataset. In most cases, the components that make up the project costs were not reported. However, it is likely that these incorporate different components, such as treatment, monitoring, design, oversight, and health and safety. The median reported total cost for all SVE projects was approximately USD206,000, with most projects having a total cost between USD100,000 and USD400,000. 

Pilot-scale treatability studies are enlargements of bench-scale tests, which more closely approach the full-scale project. The objective of pilot-scale tests is to verify treatability outside of a laboratory setting and verify the actual field conditions. Many pilot-scale studies are performed at the actual project site. Data from pilot-scale studies are used to design full-scale field operations. A pilot test may include the following ... 

As analytical chemists, we are often called upon to participate in studies that require the measurement of chemical or physical properties of materials. In many cases, it is evident that the measurements to be made will not provide the type of information that is required for the successful completion of the project. Thus, we find ourselves involved in more than Just the measurement aspect of the investigation —we become involved in carefully (re)formulating the questions to be answered by the study, identifying the type of information required to answer those questions, making appropriate measurements, and interpreting the results of those measurements. In short, we find ourselves involved in the areas of experimental design, data acquisition, data treatment, and data interpretation. 

Table 1 gives cost and maintenance information for the frozen barrier installed as part of the U.S. Environmental Protection Agency Superfund Innovative Technology Evaluation (SITE) demonstration at Oak Ridge National Laboratory (ORNL). Table 2 gives physical design data for the ORNL project.

The following list contains a summary of the design projects set by the I. Chem. E. since 1959, more details are included in the actual papers, e.g. process description, design data, references, etc. It should be possible to design these plants using information that is freely available in the technical literature. 

Design data and other process information are obtained during the development stage. This information is used as the basis for carrying out the additional phases of the design project. A complete market analysis is made, and samples of the final product are sent to prospective customers to determine if the product is satisfactory and if there is a reasonable sales potential. Capital-cost estimates for the proposed plant are made. Probable returns on the required investment are determined, and a complete cost-and-profit analysis of the process is developed. 

The Final Report does not have to physically include all of the supplemental project or facility design data that was used in the review. This data can be referenced, so as long the referenced location is adequately described and the information is maintained. 

These must be prepared for each project to reflect its specific requirements -process, site conditions, safety, specific equipment, etc. A complete project specification must go into the details of equipment design data sheets, spelling out all the information, process, and/or mechanical, required to fabricate a piece of equipment.
