Equipment configuration general

The influence of the photons emitted by a Am XRF excitation source below 59.6 keV on sample fluorescence production has been analyzed and general method for evaluating the contribution of the various lines from the source in specific equipment configurations is presented by Delgado et al. (1987). A typical L X-ray spectrum of Pb by Am source (Kumar et al. 1999) is presented in Fig. 1.5, which also shows the peaks due to elastically- and inelastically-scattered photons from the Am source. 

Scrubber types most frequently used for drying processes in general terms of geometric type, collection mechanism, equipment configuration, and method of operation are presented in Table 45.10 and Figure 45.4. 

Verification of the technical performance of AIS eAtoN lies primarily in determining that the system is operational and performs the required functions. General guidance on this subject may be found in the appropriate IAEA guidelines (IAEA G1028). Guidance on verification of AtS equipment should be found in the technical specifications, acceptance test procedures and maintenance test procedures appropriate for specific equipment configurations. 

Offshore, well control equipment and associated operations present some differences from that seen and used onshore. In some instances onshore equipment can be employed, but the offshore environment generally dictates a modification of equipment and procedures. There are several different well configurations used offshore, often on the same well at different drilling intervals, and each configuration has specific well control procedures that should be followed. A well may be equipped with a surface blowout preventer stack a subsea blowout preventer stack, riser and diverter system a riser and diverter system with no blowout preventer a diverter only or a riserless system with no well control equipment. 

General Considerations. Continuous mass processes for polystyrene have been in commercial use since the 1930 s, and for rubber-modified polystyrene (HIPS) since the 1950 s. Much of the information on equipment design, process configuration and operating parameters connected with continuous processes is found in the patent literature. There are inherent limitations to such sources. Recognizing this, we will provide...
