Equipment list

The equipment list is a compilation of all the equipment that costs more than a pump, together with enough information about each piece for its cost to be estimated. The list is developed directly from the detailed flow sheet. Each piece of equipment shown on the flow sheet should appear on the equipment list. The symbols assigned to each piece of equipment are included on the equipment list to provide a cross-reference between the list and the detailed flow sheet. 

To determine the cost of purchasing and installing each piece of equipment, the following major factors must be specified  

Maximum temperature if the equipment is to run above the ambient temperature 

Special features such as jackets on heat exchangers or special conditions such as the burying of a storage tank 

The effect of these items on the cost is discussed in Chapter 9.

Safety Systems. Major expenditures here include the flare system (the flare structures and large lines extending throughout the plant) and the iirevvater system (high-capacity pumps and extensive piping). Safety systems, fortunately, are usually given particular attention. At this study phase, the main thrust should be to check the completeness of licensor equipment lists for cost estimation purposes. 

Check HVAC maintenance records against equipment lists. Collect existing maintenance and calibration records and check them against the construction documents (e.g., equipment lists and mechanical plans). Equipment that has been installed in inaccessible or out-of-the-way locations is frequently overlooked during routine maintenance. 

Maintenance Unavailability shift supervisor s logs and minimum equipment lists so unavailability of equipment needed to mitigate a shut-down accident. 

The development of the CCPS Taxonomy was essential, and it is one of the most useful results of preparing this book. The first step in creating the taxonomy was to develop a list of equipment to be included. This was accomplished by reviewing the equipment lists of over 300 different chemical processes summarized by SRI International in their Process Economics series. These lists were used in conjunction with the CCPS Equipment Re-... 

The main objective of the In-Plant Reliability Data System (IPRDS) was to develop a comprehensive and component-specific data base for PRA and other component reliability-related statistical analysis. Data base personnel visited selected plants and copied all the plant maintenance wor)c requests. They also gathered plant equipment lists and plant drawings and in some cases interviewed plant personnel for Information on component populations and duty cycles. Subsequently, the maintenance records were screened to separate out the cases of corrective maintenance applying to particular components these were reviewed to determine such things as failure modes, severity, and, if possible, failure cause. The data from these reports were encoded into a computerized data base.

Figures 12-lA, 12-lB, 12-lC, and 12-lD present a general view of the usual ranges of capacity and speed operation for the types of compression equipment listed. For pressure conversions of Figure 12-lB, 1000 psi = 6.8947 mpa.

Detailed design— preparation of engineering drawings and equipment lists needed for constraction. 

Table 11.4 lists reactors used for systems with two fluid phases. The gas-liquid case is typical, but most of these reactors can be used for liquid-liquid systems as well. Stirred tanks and packed columns are also used for three-phase systems where the third phase is a catal5hic solid. The equipment listed in Table 11.4 is also used for separation processes, but our interest is on reactions and on steady-state, continuous flow. 

The selection guides given by Lowrison (1974) and Marshall (1974), which are reproduced in Tables 10.12 (see p. 465) and 10.13, can be used to make a preliminary selection based on particle size and material hardness. Descriptions of most of the equipment listed in these tables are given in Volume 2, Chapter 2 or can be found in the literature Perry et al. (1997), Hioms (1970), Lowrison (1974). The most commonly used equipment for coarse size reduction are jaw crushers and rotary crushers and for grinding, ball mills or their variants pebble, roll and tube mills.

The equipment list should include all laboratory equipment that is going to cost more than 1,000. This would include special testing devices such as an Instron , an infrared spectrometer, or a chromatograph. 

The equipment list cannot be completed at this point in the design. The heat exchangers and pumps cannot be sized until an energy balance is completed. The energy balance, in turn, cannot be performed until the layout is established, and this depends on the approximate size of the equipment. Thus, all equipment except for heat exchangers and pumps will be sized at this point in the design. The rest will be sized after the energy balance is complete. 

Table 5E-1 gives a partial equipment list. The key to the numbers is given in Table 5E-2. The reasoning behind this equipment list follows.

Together we need 3 reactors for MIPS and HIPS, making a total of 7 reactors needed. An eighth will be installed as a spare. This will allow full production to continue if cleaning out the reactors becomes more of a problem than expected. Obviously a standard size reactor will be chosen it may be somewhat below the size calculated. (A similar statement can be made for each piece of equipment listed.)... 

When the energy balance is complete, or even while it is being calculated, the engineer should complete the details of the equipment list by sizing all the remaining equipment that is larger than a pump. Again, only the information needed to specify... 

As with the equipment list in Chapter 5, there are numerous rules of thumb that can speed up calculations. A few that have not already been given, and some ranges, follow. 

An addendum to the equipment list is given in Table 8E-1. The basis of these specifications follows.
