Process flow diagram equipment summary table

Equipment Cost Summary. In this section a table is prepared, containing the estimated purchase price of every equipment unit in the process flow diagram, identified according to the unit number and unit type on the process flow diagram and in the equipment list. The sources of the prices should be identified (graphical or tabulated cost data, a quotation from a specific manufacturer, etc.). 

It is clear that the PFD is a conplex diagram requiring a substantial effort to prepare. It is essential that it should remain uncluttered and be easy to follow, to avoid errors in presentation and interpretation. Often PFDs are drawn on large sheets of paper (for exanple, size D 24" x 36"), and several connected sheets may be required for a conplex process. Because of the page size limitations associated with this text, conplete PFDs cannot be presented here. Consequentiy, certain liberties have been taken in the presentation of the PFDs in this text. Specifically, certain information will be presented in acconpanying tables, and only the essential process information will be included on the PFD. The resulting PFDs will retain clarity of presentation, but the reader must refer to the flow summary and equipment summary tables in order to extract all the required information about the process. 

I n Chapter 1, the information provided on a process flow diagram, including a stream table and an equipment summary table, was presented. In the next four chapters, this information will be used as a basis for estimating... 

The beginning of the process is the generic block flow process diagram Although the flow summary table at this stage is based on crude assunptions and the equipment summary table is far from the final equipment specifications, they help keep the chemical engineer cognizant of key choices that need to be made.
