Feasibility tests

After this feasibility test, a library consisting of 50 types of beads each containing a different dipeptide selector attached through its C-terminal group was prepared and screened (Fig. 3-6) [84]. The first amino acid residue (aa 1) was chosen from a... 

The validity of the model is tested against the experiment. A ISOOcc canister, which is produced by UNICK Ltd. in Korea, is used for model validation experiment. In the case of adsorption, 2.4//min butane and 2.4//min N2 as a carrier gas simultaneously enter the canister and 2.1//min air flows into canister with a reverse direction during desorption. These are the same conditions as the products feasibility test of UNICK Ltd. The comparison between the simulation and experiment showed the validity of our model as in Fig. 5. The amount of fuel gas in the canister can be predicted with reasonable accuracy. Thus, the developed model is shown to be effective to simulate the behavior of adsorption/desorption of actual ORVR system. 

As a kind of specialty solutions for the real hard cases where fouling is intense and unavoidable, IMM first proposed ideas to develop special micro mixers for fouling-intense reactions and conducted feasibility tests, among them very fast organic reactions with spontaneous precipitation such as the amidation of acetyl chloride in THF [134]. The Forschimgszentrum Karlsruhe developed special anti-foul-ing coatings in cooperation with partners [135]. 

NPL Superfund Records of Decision (RODs) were loeated for 24 of the 27 currently listed NPL sites where the HazDat database lists 3,3 -diehlorobenzidine as a eontaminant. A ROD is a legally binding doeument that states the results of investigation and feasibility testing at hazardous waste sites and tells what techniques will be used to remediate the site. At four of the sites, 3,3 -dichlorobenzidine was verified as a contaminant. The RODs for the other 20 sites did not mention 3,3 -dichlorobenzidine as a contaminant of concern (i.e., one that warrants development of cleanup criteria and a choice of remedy). Affected soil was removed from three of the four contaminated sites. Only one site, Bofors Nobel in Michigan, required development of a cleanup criteria (CPMA 1998). 

In the area of extracting solutes from aqueous solutions, many systems have been screened in feasibility tests that have used carbon dioxide as a solvent. A partial list of the solutes includes ethanol, acetic acid, dioxane, acetone, and ethylene glycol. The reason for these efforts has been potential low energy costs compared with distillation and the environmental advantages of using carbon dioxide. 

A feasibility test is conducted to ensure that constituents that would inhibit the Aqua-Fix absorption capabilities do not exist in the water. This test, including characterization, testing, and a report is 275.00 per contaminant. Two hundred dollars of the cost can be credited toward an order of 1000.00 or more if placed within 60 days of the issuance of the report (D14690R, p. 4). 

IGT has developed a treatability protocol for the MGP-REM technology to determine cleanup rates and the preferred mode of treatment (landfarming, soil slurry, or in situ). The protocol consists of three phases Phase I is a feasibility test comparing a variety of techniques and is completed within 2 to 3 months phase II is a bench-scale optimization under simulated field conditions and phase III is the field-scale evaluation.

Many earlier researchers neglected the fact that degrees of freedom are usually available in a process plant (HEN) which can be manipulated during plant operation so as to maintain feasibility (review by Grossmann et al., 1983). By not allowing the control variables to vary, the feasibility test can be unnecessarily conservative. 

In this section, general mathematical formulations and graphic interpretations are presented for several resilience analysis problems (1) feasibility test, (2) resilience (flexibility) test, (3) flexibility index, and (4) resilience index. 

A HEN is feasible for assumed, fixed values of uncertain variables 8 if control variables z can be found to satisfy the reduced set of constraints. The HEN feasibility test can be formulated as follows to minimize the maximum constraint violations (Halemane and Grossmann, 1983) ... 

For the feasibility test, stream split constraints (Bl) are linear In particular, each g,y is constant since the feasibility test is for specified supply temperatures. Also note that the energy balance and energy recovery constraints are not included in this feasibility test they are used to determine constants aijh cijh and vk, in the stream split, load, and A7 constraints. 

Thus simulation (e.g., the feasibility test in Section III,A,1 with area constraints replacing the ATm constraints) and costing should be used to evaluate the final design choices. 

The e-value convergence tests of CTP-e, the feasibility tests ofCTP, and the e-convergence tests of CTD-e are necessary for e-bound improvement. The e-convergence tests are sufficient for one of the following ... 

For composite samples the method discriminated separate Ti02 and CaC03 components and accurately determined their proportions. In addition, in combination with ultrasonic attenuation measurements, the size fractions of iron ore slurries below 10 and 30 pm were determined to within 1.3% and 1.0% respectively when compared with laser diffraction measurements [272]. According to Coghill et. al. velocity measurements are complementary to attenuation methods but better suited to the finer size fractions. A description of the analyzer and the results of plant feasibility tests and on-line installation has been presented [273]. 

Many optimizers use the feasibility test Z It l < optacc (cf. Eq. 36). The model generates a path constraint, x(rj), for which a value of 1 represents an insignificant constraint violation. Using... 

The SO2 recovery process is being studied in both bench-scale and fiuid-bed pilot equipment (1,2,3). Initial feasibility tests were conducted in small fixed-bed reactors to determine the most effective carbon for SO2 removal and to evolve the regeneration sequence for minimum carbon loss. Continuous operation of the various process steps was evaluated under simulated conditions in fiuidized-bed pilot equipment. 

The required information about the distillation boundary is obtained from the pinch distillation boundary (PDB) feasibility test [8]. The information is stored in the reachability matrix, as introduced by Rooks et al. [9], which represents the topology of the residue curve map of the mixture. A feasible set of linear independent products has to be selected, where products can be pure components, azeotropes or a chosen product composition. This set is feasible if all products are part of the same distillation region. The singular points of a distillation region usually provide a good set of possible product compositions. The azeotropes are treated as pseudo-components. 

The evaluation of a separation sequenees requires information about the feasibility and the cost of the individual separation tasks. Determining the minimum energy demand of a separation has been foimd to be a good way of estimating the cost of a distillation system, because operation cost are dominated by the energy demand and investment cost are closely related to the vapor flow rate in the column [10], The minimum energy demand can be calculated using the RBM shortcut. The feasibility of the individual separation tasks can be checked with the application of PDB feasibility test.
