Industrial case

It is emphasized that the delta L law does not apply when similar crystals are given preferential treatment based on size. It fails also when surface defects or dislocations significantly alter the growth rate of a crystal face. Nevertheless, it is a reasonably accurate generahzation for a surprising number of industrial cases. When it is, it is important because it simphfies the mathematical treatment in modeling real crystallizers and is useful in predicting crystal-size distribution in many types of industrial crystallization equipment.

The practical applications for cryogenic turboexpanders are best illustrated by industry case history reports that follow. 

A short review of the CA process is given before proceeding with the applications of the technique to several industrial case studies. The three key stages of CA are shown in Figure 2.24 within the simplified process of assessing a design scheme. 

In our third step, we convert the compositions to a kg-moles-per-second basis. For this example (as well as many common industry cases), the ideal gas law can be used n = PV/RT, where n = number of moles... 

Chapter 7, Case Studies, uses examples that illustrate the application of the various error analysis and reduction techniques to real world process industry cases. 

Fig. 10-16 A simple schematic of the carbon cycle. Part (a) is the pre-industrial case, and part (b) shows the contemporary reservoirs and fluxes, in Pg C and Pg C/yr, respectively (Pg C = lO g C). This diagram of the carbon cycle is similar to those presented in Chapters 4 and 11. (Reprinted by permission from Nature (1993). 365 119-125, Macmillan.)...

Mass balances of four case studies were evaluated. Additionally, an LCA is considered for the last case study. Case study 1 and Case study 2 are academic and include a comparison between alternative synthesis protocols. In the industrial Case study 3 and Case study 4, a comparison of the steps of a scale up was possible. 

Mass indices and environmental factors (equations (5.1) and (5.2)) have been introduced in Section 5.1. For confidentiality reasons, neither chemical names nor exact quantities are specified concerning the industrial case studies. Instead, masses are expressed relatively to input amounts at the laboratory scale. The imit (kg kg ) expresses how many kilograms of substance are needed to produce one kilogram of product. Abbreviations used in captions of the figures are explained in Box 5.2.

The industrial case study presented in this section is taken from the petrochemicals industry. The project is in the design phase and as such the design model will be used to determine the design which leads to the minimum capital cost, while using the PIS operational philosophy. For secrecy reasons the example has been modified and the names of the raw materials and products have been changed to the generic form.
