Total equipment cost

Category Eactor Estimates. Various capital categories can be related to total equipment costs by factors, reported as percentages of equipment cost. Both purchased equipment costs, including pumps, tanks (qv), and instmments and deHvered equipment costs, excluding instmments, but including some off-sites, have been used in this approach (1,2). 

For liquid substrates the most significant equipment cost is fermentation, ranging from 43 to 51% of the total equipment costs. See Table 4.10. 

Using Eqn. (7..7-4) to calculate the purchased cost of equipment, the following expression is obtained for the total equipment costs ... 

Total equipment cost (TEC) include equipment purchase, shipping, taxes, and freight. 

For the above estimate, total equipment costs for the SFC system was estimated at 35,540. This included the vertical fin coalescing unit, oleophilic ceramic granules, pumps, a pneumatic control system, and such ancillary equipment as a 2000-gal bulk tank with fittings, a skimmer, necessary switches, valves, piping, and wires (D11018P, p. 28). 

Inits economic model (3), NRELused the discounted cash flow method to calculate the yearly total equipment cost for different process sections. To simplify economic comparisons between the two pretreatment designs,... 

Pressure (psi) Temp (°C) Total equipment cost ( ) Equipment cost (per yr)( ) Operating cost (per yr) ( ) Total cost ( /yr) Total cost ( /gal)... 

It was estimated that the total equipment cost was 1.69 million for this process. The major portion of this equipment cost was attributed to the chromatographic columns which was about 49%. The installation of this... 

Estimate the total equipment cost of the absorber unit in 2001 dollars. The total gas absorber unit equipment cost (TEC) is the sum of the individual equipment costs ... 

According to the EPA Manual procedure, the PEC is made up of three elements in addition to the total equipment cost (1) freight cost, (2) sales taxes, and (3) instrumentation cost. The percentages the EPA Manual assigns to these costs are 5%, 3%, and 10% of the total equipment cost, respectively. For this problem, the costs are, accordingly, as follows ... 

In the factor methods for cost estimating, first calculate the purchased or delivered cost of all major equipment, for example, distillation columns, reactors, pumps, heat exchangers, etc. Then multiply the total equipment cost by factors to estimate the various other components of the depreciable capital cost given in Equation 2.2, such as piping and electrical wiring. Thus, we arrive at the cost of installing all the equipment and supplying all the services needed to produce an operational process.

The system is equipped with a telemetry control system and a fully automated backup system. Each bank of three irradiation chambers has two units on line at all times, with the third unit serving as a backup. In the event that the UV intensity decreases below acceptable limits (20,000 pW-s/cm ) in any of the chambers, the automatic butterfly valve will close, stopping flow through the chamber at that time, the automatic butterfly valve on the standby unit will open. The alarm system is also activated if UV intensity decreases below acceptable limits in any of the chambers. The UV alarm system is interfaced with the automatic dialer and alarm system. In 1987, total equipment costs for the six-unit UV irradiation system with butterfly valves was US 74,587. 

Although one can progressively account for one additional complexity at a time, it is also possible to take a direct leap to a problem with a combination of complexities, as illustrated in this case study on NOx absorption in the manufacture of ifitric acid. The NOx absorption system may contribute about 40% of the total equipment cost. Hence, optimal design of the NOx absorption tower is important major cost-determiifing factors should be identified and selectively addressed with greater rigor. 

The total equipment purchase cost was estimated to be around 2.8 million. The most expensive piece of equipment is the bioreactor used for cell culture and virus propagation, priced at 506,000. The cost of unlisted equipment (including the equipment used in the inoculum preparation section) was assumed to represent 20% of the total equipment cost. 

The total number of trays is a compromise between the total equipment cost and the total utility cost. The optimum total number of trays and the optimum feed-tray location are determined to minimize TAC. The calculation procedure of Douglas is followed with the annual capital charge factor of 1 /3. The utility costs include the steam and cooling water for the operation of reboiler and condenser. The total operating costs include the utility costs and the entrainer makeup cost. The Aspen Plus simulation results for the three entrainers are summarized in Tables 9.10 to 9.12.
