Installation Equipment layout

Wellhead equipment layout for sand coking in the bottomhole zone is shown on Fig. 89. A wellhead shut-in vdve is installed to seal off the well when necessary also a specially-designed lubricator provided with cable line packer is used so that the heater can be lowered and raised. To measure the amount of air injected, flow meter type DP-430 can be employed. Several electrical measurement instruments, such as the potentiometer and megohmmeter are also necessary.

Conduct test operations with dununy loads to identify blind spots. If equipment layout design cannot be modified, install necessary mirrors and/or video cameras to increase visibiUty. 

Unit layout as installed is the next step of preparation. This may take some effort if analysts have not been involvea with the unit prior to the plant-performance analysis. The equipment in the plant should correspond to that shown on the PFDs and P IDs. Wmere differences are found, analysts must seek explanations. While a hne-by-line trace is not required, details of the equipment installation and condition must be understood. It is particularly useful to correlate the sample and measurement locations and the bypasses shown on the P IDs to those ac tuaUy piped in the unit. Gas vents and liquid (particularly water-phase) discharges may have been added to the unit based on operating experience out not shown on the P IDs. While these flows may ultimately be small within the context of plant-performance an ysis, they may have sufficient impact to alter conclusions regarding trace component flows, particularly those that have a tendency to build in a process. 

As the process moves from the process development stage to the design and construction stage the chemistry, unit operations, and type of equipment have been set. The design and construction stage needs to focus primarily on equipment specifications, piping and instrumentation design, installation details, and layout for an inherently safer installation. 

Regarding fires, water is the primary extinguishing agent, and it should be available in adequate supply and pressure at all of the locations in the plant. The layout for various types of installations and the appropriate recommendations are found in the standards of the National Fire Protection Association. Fire hydrants, hose lines, automatic sprinkler and water spray systems should all be a part of the permanent equipment facilities of the plant. 

FPN) Through the exercise of ingenuity in the layout of electrical installations for hazardous (classified) locations, it is frequently possible to locate much of the equipment in less hazardous or in nonhazardous locations, and, thus, to reduce the amount of special equipment required.

All tests within the activities of Section 6.2.4 are recorded and documented in file (F). A similar test protocol for the loading and unloading installation GT50/95/2 must be established. However no example can be given, since this kind of equipment can be based on very different design layouts. 

A 50,000-gal tank was installed adjacent to the test area. This tank was equipped with an aerator, nutrient feed equipment, and a submersible discharge pump. The physical layout of this system was very similar to that shown in Figure 12.11. 

The use of installed spares and rotating equipment out of service for periodic maintenance should reduce the impacts on production rate from failures in equipment. This conclusion assumes that the resulting complexity of piping layout and increased manipulation of piping connections does not negate the goal of assuring process reliability. 

Reactants not transformed into urea are recycled to the reactor by an ejector. Main equipment is installed at ground level this layout... 

Autoclaves are usually installed in high, light rooms equipped with traveling hoists. Figure 56 on page 376 shows, in cross section, a factory layout for a dye plant with its adjoining autoclave room. The illustration shows how the completed reaction mixture is transferred directly from the autoclave to the processing rooms. 

There is usually a need to provide additional drawings to clarify certain aspects of the design. A typical example is the provision of layout drawings for instrument/interface rooms and for control rooms to show the location of key items of equipment and their relationship to other equipment that may already be installed. 

The second pass of the PHA is done after the P ID s and preliminary layouts are complete. This second analysis will indicate what equipment, installation methods, and process controls will be required to operate the plant safely. This analysis should be completed before the estimate for the Authorization Request is generated.
