Technical information flow sheets

The chemical process industries are competitive, and the information that is published on commercial processes is restricted. The articles on particular processes published in the technical literature and in textbooks invariably give only a superficial account of the chemistry and unit operations used. They lack the detailed information needed on reaction kinetics, process conditions, equipment parameters, and physical properties needed for process design. The information that can be found in the general literature is, however, useful in the early stages of a project, when searching for possible process routes. It is often sufficient for a flow-sheet of the process to be drawn up and a rough estimate of the capital and production costs made. 

Preparation of technical data sheets Figure 4.8 shows an example of a technical data sheet of a pump. The most important data fields to be filled by the plant manufacturer (in Figure 4.8 in italics) are the pump head and the flow rate in the design point. The necessary information concerning the medium can again be gathered from the enclosed media data sheet. Other technical requirements can be stated in the relevant customer specification or in a QA-plan required to be enclosed, too. All other information has to be filled in by the pump supplier (in Figure 4.8 in bolt print).
