Elevators planning

To start a detailed planning study, space requirements must be known for various products, by-products, and r iw materials, as well as for process equipment. A starting or reference point, together with a directional schematic flow pattern, will enable the design engineers to make a trial plot plan, as e.xplained below, A number of such studies will be required before a suitable plot and elevation plan can be chosen. 

An elevation plan should be drawn to scale showing the vertical relationships of all elevated equipment. These drawings, as well as the plot plan, are usually sketched by the engineer and then redrawn to scale by a draftsman.

Scale Models. Recent developments in the u of scale models have shown the advantages of this method over the detailed two-dimensional method. Figure 5-4 is a view of a study mode costing less than 1,000. It was made from blocks of wood and cardboard set on in. to the foot scaled paper. This low-cost model is used chiefly to develop plot and elevation plans and cannot be used for piping and utilities layout. Figure 5-5 is a more complete model costing 5,000 to 10,000. It is...

Figure 12 shows the plan and elevation views of a process unit piping (9). A dmm is supported off the piperack. Heat exchangers are located far enough back from the support columns so that they are accessible and their shell covers can be removed. Pumps are located underneath the piperack, but sufficient room is provided for maintenance equipment to access the motors and to remove the pump if necessary. The motor is always oriented away from the process equipment and located on that side of the piperack. Instmment valve drops are shown supported from the columns. The instmment trays themselves mn on the outside of the support columns. Flat turns are only made from the outside position of the piperack. Nozzle-to-nozzle pipe mns are made whenever possible. Larger lines are located on the outside of the piperack. Connections to nozzles above the rack are made from the top... 

Flare noise (roar of combustion) is the most serious because it is elevated and the sound carries. The flare can be located at a remote distance from the operating unit or surrounding community. Noise of steam injection into the burner can be reduced by using multiple no22les. Furnace noise from air intake, fuel systems, and combustion blower forced draft/induced draft (FD/ID) fans can be reduced by acoustics. The plot plan should be evaluated for noise generation and to find the means of alleviating or moving noise to a less sensitive area.

(middle and bottom) Elevation and plan views of Ballast rings (right) and Cascade Mini-Rings (left). Note how high aspect ratio of former permits occlusion of interior surfaces. Low aspect ratio of Cascade Mini-Rings, on the other hand, favors orientation that exposes internal surfaces for excellent film formation, intimate mixing, and gas-liquid contact.
