Tank capacity tables

The uncertainties of quantity assessment of a tank-gauging system depend on the measuring uncertainties of the installed instruments, tank capacity table (TCT) and installation. [Pg.730]

Unexpected product movements can then be signaled to the operator by an alarm. Statistical analysis of static data from the tank-gauging system and dynamic data from flow meters could also be used to improve the accimacy of the tank capacity table. Cross-correlation of gauges versus fiow meters could further reduce measurement uncertainties. With high-accuracy tank-gauging instruments combined with powerful computing platforms, automatic reconcihation becomes realistic. [Pg.745]

Callow Tanks.— These tanks are illustrated in Figs. 9 and 10. For separation, where a clean liquid overflow is desired, the use of the smaller sizes shown in Fig. 9 is not to be recommended. As an inspection of the capacity table accompanying Fig. 9 will show the tanks have a small capacity and are suitable to small operations. Used in batteries they occupy more space than a single tank of equal settling area and capacity and there is the extra annoyance and expense in insuring the free running of the discharges. A battery of 50 8-ft. tanks requires not... [Pg.278]

Unloading is possible every day. The tank capacities at both sites are shown in Table 4-4 whereas the tank capacity at the sea port is assumed to be 75,000 tons. [Pg.189]

The main difference in the three synthesis routes detected so far— DA-SHF, DA-SHCF, and DA-SSCF—is the hydrolysis and fermentation reactor distributions. Then, a comparison of annual fixed costs for reactor tanks is used in this level as a final factor. The reacting volume was estimated by relating the volume flow obtained from the simulations and the dilution rate reported in Table 2.11. The total reactor volume was then estimated as 20% above the reacting volume, and four different tank capacities were considered in order to achieve the total reactor volume (Table 2.12). The tank cost estimations were based on the data reported by Aden et al. (2002) with a linear depreciation in 10 years. Table 2.13 shows the annual fixed cost and the annual production for each option, from which unit costs per gallon of ethanol were estimated. [Pg.56]

Investment, Costs, and Prices for Barley and Malt. Estimated malthouse investment (1993) and costs for a new malthouse with annual capacity of 120,000 t are shown in Table 2. This malthouse is equipped with twelve 1,700-bushel steep tanks, eight 10,000-bushel germination compartments, and two double-deck kilns. The kilns are equipped with standard heat recovery units and indirect heat. [Pg.483]

Tank vent equipment ratings are expressed as free air capacity at 14.7 psia and 60°F, and in order to handle vapors from liquids of the chemical and petrochemical industry, corrections must be made. Likewise corrections are required to recognize temperatures other than 60°F, refer to Table 7-16. [Pg.469]

Note, most manufacturers tables or charts give SCFH capacities at 14.7 psia and 60°F, and these must be corrected by the gas laws to the artwa/volume at flowng conditions in order to represent the actual performance of the system. The tables or charts of the manufacturers read in SCFH for selected relief device setting and for tank pressure, expressed as air at SCFH (see Figures 7-37A and 37B). [Pg.469]

Note Interpolate for intermediate tank sizes. Tanks with a capacity of more than 180,000 barrels require individual study. Refer to Appendix A for additional information about the basis of this table. [Pg.470]

The capacity of a valve as read from a manufacturer s table or chart is 45,000 cubic feet per hour oifree air (14.7 psia and 60°F). What is the capacity of the valve in terms of the vapors expected to pass through the valve under the rated conditions at the same setting If methanol is in the tank at 55°F... [Pg.470]

Convert the free air rates to the proper product in the tanks using the corrections outlined in a previous paragraph. Keep in mind that the manufacturer s rating tables are in free air however, the actual process calculations provide flows in terms of the actual liquids at actual temperatures and pressures. It is important that the manufacturer be given the actual fluid conditions to ensure proper capacity rating. [Pg.476]

Determine whether it is more economical for a 150,000,000 lb/yr polystyrene plant to buy styrene in 3,000-ton or 1,000-ton shipments. The cost of shipping is 0.230/ton mile in the former case and 0.260/ton mile in the latter case. The distance to be shipped is 1,250 miles. Assume the former requires a 26-day storage capacity and the latter a 17-day storage capacity. (See example in Chapter 3.) The value of money is 10%. Use the tank sizes given in Table 5-2 only. The Net Present Value method should be used. [Pg.333]

Table XVI shows two experiments which compared the same wine stored under different conditions (46). In both cases, the wine richer in anthocyanins is also that which is less colored. The mediation of tannins is not enough to explain the differences in color these can only be explained by a different structuring of the anthocyanin molecules. More specifically, the anthocyanin molecules will be reduced to colorless flavenes (14) during fermentation, which is a reductive process. The reoxidation occurs more rapidly in wooden casks which allow better oxygen penetration than metal storage tanks or large capacity casks. However, the flavenes themselves are relatively instable and can be irreversibly hydrolyzed into dihydrochalcones (16). This explains the lack of relationship between anthocyanin concentration and color, independent, of course, of the eventual appearance of free sulfur dioxide.
