House, design

While successbil and economical system designs can be devised by experienced process engineers, the competent technical aid available from equipment supphers has led to a growing trend toward the purchase of complete systems, even on small jobs, rather than iu-plaut assembly from components on the basis of in-house designs. An idea of the change in capital investment for typical pneumatic-conveyor systems as a function of increasing transfer rates is given in Table 21-12. 

The current needed for cathodic protection by impressed current is supplied from rectifier units. In Germany, the public electricity supply grid is so extensive that the CP transformer-rectifier (T-R) can be connected to it in most cases. Solar cells, thermogenerators or, for low protection currents, batteries, are only used as a source of current in exceptional cases (e.g., in sparsely populated areas) where there is no public electricity supply. Figure 8-1 shows the construction of a cathodic impressed current protection station for a pipeline. Housing, design and circuitry of the rectifier are described in this chapter. Chapter 7 gives information on impressed current anodes.

Despite the market explosion of data management software, there are still situations which justify in-house development. When it is appropriate to develop software In-house, design philosophies such as those Implemented in the MARS system will help reduce the development and maintenance investment and enhance the effectiveness of the system.

Test equipment used included load cell hardness testers, in-house designed computer operated systems and commercial crush test apparatus. Representative samples were provided and a test portion of 50 to 200 pellets was obtained by riffling or splitting. The samples were then heated at 400°C for 3 hours and cooled in a desiccator, since moisture absorption by hygroscopic catalytic materials has been shown to affect crushing strength. (3)...

The acquisition of the mass spectra for peptide and protein imaging is done in our lab on commercial MALDI TOF instruments (Voyager sSTR, 4700 Proteomics Analyzer Applied Biosystems, Framingham, MA) equipped with a Nd YAG laser. The acquisition of the data is controlled by an in-house designed software (MALDI MS Imaging Tool, MMSIT). The area to be scanned is specified as a pattern of points, equidistant from each other. The distance is chosen referring to the diameter of the... 

The process of hydrogenation of canola oil is usually carried out batch-wise. There are various reactor designs in use. Often, in-house designs are used, but many companies in the field of supplying the edible oil industry with process equipment are able to furnish proven hydrogenation and catalyst removal equipment. 

Isolated bag houses designed with breathing air, decontamination showers, and floor drains with shunt valves that allow waste water to be pretreated should be considered for dealing with highly active compounds.
