Process selection guide

The processing information (as well as material information) presented in this and other chapters has provided a variety of useful selection guides (see INDEX, Selection guide for guides throughout this book). Additional process selection guides are in the following Tables 8-45 to 8-55.

D. Select a packing and determine its packing factor from Tables 9-26A-E. Packing is selected for its expected process HETP or Kga performance, pressure drop and materials of construction for the system. Table 9-17 presents summary comments for applications. Selection guides are as follows ...

Table 10.7, adapted from a similar selection guide by Parker (1963a), shows the basic features of the various types of solids dryer used in the process industries and Table 10.8, by Williams-Gardner (1965), shows typical applications. 

A variety of equipment has been developed for gas cleaning. The principal types used in the process industries are listed in Table 10.11, which is adapted from a selection guide given by Sargent (1971). Table 10.11 shows the general field of application of each type in terms of the particle size separated, the expected separation efficiency, and the throughput. It can be used to make a preliminary selection of the type of equipment likely to be suitable for a particular application. Descriptions of the equipment shown in Table 10.11 can be found in various handbooks Perry et al. (1997), Schweitzer (1997) and in specialist texts Strauss (1975). Gas cleaning is also covered in Volume 2, Chapter 1. 

Irreversible CYP inhibition, especially when considered as a cause of chemically reactive metabolites, raises a number of issues that should be considered early in the drug discovery process. Careful evaluation of the structural features of the lead series as well as screening for MBIs early in the drug development process should guide series selection and optimization with the goal of avoiding the introduction of potentially risky moieties into new chemical entities. 

Process Selection. Table I presents general performance data to guide process selection of acid gas removal facilities. Several surveys have recently appeared in the literature ( 4, 5). 

One important way in which thermodynamics is utilized in hydrometallurgical process development is as a guide to experimental planning and process selection and evaluation. A high degree of accuracy is not needed at this stage of process development. Estimates which are within 15 to 20% of the true value are frequently adequate for making feasibility calculations.

This section is primarily concerned with the reviewing water treatment program selection process for open recirculating cooling systems and demonstrating the kind of information that may then be represented in a vendor s standard program selection guide. 

A simplified material selection guide has been provided to determine the general chemical compatibility between the membrane (and its accessory components) and the process su eam. The guide is primarily for relatively low temperature applications.

Knowledge of the most critical aspect of the process can guide the sometimes difficult selection process. For example, the requirement of a very dry product with strict impurity levels suggests a filtering centrifuge. A product with a feed rate of 150 gpm, without wash requirements, would lead us to a continuous sedimentation centrifuge.
