Generalized operator

The operations group will develop general operating and maintenance objectives for the facilities which will address product quality, costs, safety and environmental issues. At a more detailed level, the mode of operations and maintenance tor a particular project will be specified in the field development plan. Both specifications will be discussed in this section, which will focus on the input of the production operations and maintenance departments to a field development plan. The management of the field during the producing period is discussed in Section 14.0.

The pulsed-plate column is typically fitted with hori2ontal perforated plates or sieve plates which occupy the entire cross section of the column. The total free area of the plate is about 20—25%. The columns ate generally operated at frequencies of 1.5 to 4 H2 with ampHtudes 0.63 to 2.5 cm. The energy dissipated by the pulsations increases both the turbulence and the interfacial areas and greatly improves the mass-transfer efficiency compared to that of an unpulsed column. Pulsed-plate columns in diameters of up to 1.0 m or mote ate widely used in the nuclear industry (139,140). 

Cells are generally operated using 1.5—6 wt % AI2O2 in the electrolyte. Saturation ranges between 6—12% AI2O2 depending upon composition and temperature. 

Fractionation columns in tar-acid refineries are generally operated under vacuum and heated by high pressure steam or circulating hot oil. Calandtia in the reboders, condensers, mndown lines, and receiving tanks are constmcted of stainless steel, or, in the case of the condensers, of tin or nickel.

Dense-media cyclones are generally operated in the (0.7-1.0) X lO -Pa (10-15-lbf in ) range. It is not advisable to go below (0.4-0.56) X 10 Pa because the recoveiy of low-specific-gravity material and the rejection of impurity are improved at higher pressures. 

Drum and disc granulators generally operate in continuous feed mode. A key advantage to these systems is the abihty to run at large scale. Drums with diameters up to four meters and throughputs up to 100 ton/hr are widely used in the mineral industiy. 

Within these basic principles there are many types of electric motors. Each has its own individual operating characteristics peculiarly suited to specific drive applications. Equations (29-1) through (29-9), presented in Table 29-1, describe the general operating characteristics of alternating-current motors. When several types are suitable, selection is based on initial installed cost and operating costs (including maintenance and consideration of rehability). 

The contractor s SSAHP for Site C contained task- and operation-specific hazard analyses and safety and health procedures that covered general operations, but they were not specific enough for prescribing control methods and PPE for each job task. The plan identified some safety hazards for each operation but did not describe SOPs for protecting employees from these hazards. The SSAHP did, however, contain personnel and equipment decontamination procedures used at the site. 

Biological safety cabinets (BSCs) used in the United States are divided into three classes 1,11, and III. Class II cabinets are further divided into four types A, Bl, B2, and B3." In other countries, other categorization schemes are sometimes used, but usually follow the same general operating conditions. This division is quite unlike the rest of the local ventilation chapter, but since these descriptions are used whenever BSCs are used, it is practical to describe them here. 

Although OSDs can be used to optimize general operator performance, they are limited to the extent that they can identify human errors.
