Operation and Applications

Raw fermentation broth is an example of a large volume production. Rotary drum vacuum filters (RVF s) have traditionally been found in this service. Slow-settling materials or more difficult filtrations with large scale production requirements are typical applications for this type of equipment. For an overview of filter selection versus filtering rates, see Table 3, which is excerpted by special permission from Chemical Engineering/Deskbook Issue, February 15, 1971, by McGraw Hill, Inc., New York, NY 10020. 

The basic principle on an RVF is a hollow rotating cylindrical drum driven by a variable speed drive at 0.1-10 revolutions per minute. One-third of the drum is submerged in a slurry trough. As it rotates, the mycelia suspension is drawn to the surface of the drum by an internal vacuum. The surface is the filter medium mounted on top of a grid support structure. Mother liquor and wash are pulled through the vacuum line to a large chamber and evacuated by a pump. 

Applicable to a broad range of processes, e.g., pharmaceutical, starch, ceramics, metallurgical, salt, etc., many variations of the RVF have been developed, however, the fundamental cylinder design remains the same.

Coil boilers can come on line quickly, providing full steam pressure within 5 to 10 minutes. This makes them particularly suitable for smaller batch operations and applications that require a rapid but intermittent steam demand. In addition, they can provide a backup in emergency situations. 

In order to investigate the kinetics, heat of reaction and other aspects of the system, the RCl reaction calorimeter was employed. This system allows to perform the reaction in a 2 liters glass reactor, while controlling the reactor and jacket temperatures. Following the reaction, the heat released at any time period can be determined. The operation and application of this system has been discussed in numerous publications (refs. 5,6).

The separators in Figure 2.3 may be either a cyclone type, as typified by the Bradley microsizer or a mechanical air separator. Cyclone separators, the theory of operation and application of which are fully discussed in Chapter 1, may be used. Alternatively, a whizzer type of air separator such as the NEI air separator shown in Figures 1.29 and 1.30 is often included as an integral part of the mill, as shown in the examples of the NEI pendulum mill in Figure 2.21. Oversize particles drop down the inner case and are returned directly to the mill, whilst the fine material is removed as a separate product stream. 

The operation and application of streak cameras in fluorescence lifetime spectroscopy has been reviewed previously (see, e.g., Refs. 91 and 92). Streak cameras are useful in 2-D time-resolved imaging applications such as microscopy or multiwavelength array fluorometry. The operating principle is based on converting an optical pulse into a photoelectron pulse and spatially dispersing the electron image on a phosphor by means of a synchronized deflection voltage across two plates. 

This work describes the design, operation and application of the continuous GPC viscosity detector for the characterization of the molecular weight distribution of polymers. Details of the design and factors affecting the precision and accuracy of results are discussed along with selected examples of polymers with narrow and broad molecular weight distribution.

A consistent and appropriate change control procedure must he capable of tracking the system operation and application software. The controls on data are extended to the system of hardware and software that manipulates that data. Here the primary tool for control is a clear and appropriate change control procedure.

Many of these microsystems have been described, but capillary electrophoresis (CE) microchips seem to be the most widely developed. The concept of p-TAS was proposed by Manz et al. in 1990 [1] and 2 years later, electrophoresis in planar chips was successfully integrated and its use demonstrated using silicon and glass substrates [2,3]. This area of miniaturised analysis systems has grown rapidly, as is shown in two complete revisions by Manz et al. [4,5], the first dealing with theory and technology and the second one with analytical standard operations and applications, and the development continues exponentially.

The renewable energy processes will be monitored and controlled by small, fast, and economical detectors, and fiber optics will play a major role in their designs. The operation and applications of fiber-optic probes have already been discussed in connection with Figure 3.2, so only a brief summary is provided here. Fiber-optic probes can be installed in situ, whereas their readout instruments can be several hundred meters from the probe. The probe can be located in toxic, corrosive, radioactive, explosive, high- or low-temperature/ pressure, and noisy environments. Because the measurement signal is optical, the cables are immune to microwave or electromagnetic interference.

With the integration of computational science into the daily routine of chemical, physical, and biological research efforts, it is not economical to devote resources to large-scale integration of operating and application software.
