Solid/Liquid Separation: Equipment Selection and Process Design

The purpose of this chapter is twofold, firstly to introduce a methodology for equipment selection and secondly to describe the principal features of Filter Design Software (FDS). With respect to the former, a technique for preliminary equipment selection is presented and it is shown how an equipment list can be ranked to help refine further selection considerations. Descriptions of FDS illustrate how equipment selection, data analysis and equipment simulation procedures can be combined into computer software, a basic flowsheet is shown in Figure 5.1. Worked examples are given.
Although comprehensive descriptions of equipment selection are given in this chapter the specifics of data analysis and equipment simulation are presented elsewhere. Chapter 4 provides practical methodologies, theories and principles that underpin the analysis of filtration, jar sedimentation and expression tests. Chapters 6 and 7 respectively present extensive descriptions of batch and continuous filter simulations, however, an introduction to simulation is described here.
There are many solid/liquid separation techniques which have established general application within the process industries, and there are a few that are currently in their early stages of commercial exploitation. The dividing line between the two categories is open to dispute and difficult to identify in a field which is noted for innovation and development. The selection of appropriate equipment is thus a challenge to the design engineer and it is often...
