GENERAL DESIGN DATA

The consumption of utilities in a fermentation department depends upon the fermenter cycles since most of the steam and water are used to clean, prepare, sterilize and cool each batch. The data presented below are based on a one-week (168 hours) cycle including turnaround time and 1000 gallons of fermenter installed capacity (abbreviated 1000 I.c.Wk).

The fermentation department can consume up to 2/3 of the total plant electrical requirements (depending upon the recovery process), which includes mechanical agitation (usually 15 hp/1000 gal) and electrically driven air compressors. 

There is no relationship between the cubic feet of compressed air for large fermenters and their installed capacity. The compressed air required for fermenters is calculated by linear velocity through the fermenter and the square feet of cross-sectional area of a vessel, not its volume. Therefore, if volume is constant, short squat vessels require more compressed air than tall slender vessels. More on this is discussed under fermenter design.

The data analysis module of ELECTRAS is twofold. One part was designed for general statistical data analysis of numerical data. The second part offers a module For analyzing chemical data. The difference between the two modules is that the module for mere statistics applies the stati.stical methods or rieural networks directly to the input data while the module for chemical data analysis also contains methods for the calculation ol descriptors for chemical structures (cl. Chapter 8) Descriptors, and thus structure codes, are calculated for the input structures and then the statistical methods and neural networks can be applied to the codes.

While the statements made above are necessarily general, it is essential that the conceptual approach delineated be adhered to. The necessity for compiling adequate design data for the new installation, followed by examination of existing conditions against the design requirements, is paramount. 

The absorption and adsorption processes must be designed specifically for each waste-gas system. Most are relatively new processes, and generalized cost data are not available. 

Because of its expense, ion exchange is mainly useful for removing substances that are present in very low concentrations. For a discussion of various resins and some design data, see references 40 and 41. Some resins can be made reasonably selective, while others are general. In the latter case it is often desirable to remove many of the ions present in the water prior to the ion-exchange step, so a product may be obtained that can easily be recovered and purified. 

An early field of application in analytical chemistry is structure elucidation. DENDRAL was one of the first ES in general, designed to the identification of organic compounds from mass spectrometric data (Buchanan and Feigenbaum [1978]). In the 1980s and 1990s a flood of expert systems has been developed in analytical chemistry for different types of application, viz ... 

Blast resistant doors arc not "off the shelf items, They are built to order and manufacturers generally require 6 to 8 weeks after notification of approval of the shop drawings and design data to schedule and fabricate low-range doors, 10-12 weeks for mid-range doors, and 12 weeks or more for high-range doors. 

Table 4.15 relates to examples only and cannot be generalized. The data cannot be used for design purposes.
