Design differences

Clearly, in designs different from those in Figs. 16.13 and 16.14 when streams are split to satisfy the CP inequality, this might create a problem with the number of streams at the pinch such that Eqs. (16.3) and (16.4) are no longer satisfied. This would then require further stream splits to satisfy the stream number criterion. Figure 16.15 presents algorithms for the overall approach. ... 

Tipping pan and horizontal filters are also used for leaching the modus operand of the Rotocel extractor resembles that of a tipping pan filter, although the details of its design differ slightly. 

The various designs differ in the extent to which heat exchange is used, in the plan of the pipe-stiU furnace, in the distillation pressure, and in whether recycle of pitch or base tar is involved. 

Equipment Separator designs differ for the various types of materiafs to be separated. In general, magnetic separation devices can be grouped as follows ... 

Designs differ eonsiderably from one manufaeturer to another. The term seal body makes referenee to all rotating parts on a pusher seal, exeluding shaft paeking and the seal ring. The eonfiguration or options offered on the seal body may be the ehief reason to avoid the design for that partieular serviee. 

Three types of flare systems are commonly used the elevated flare, the ground flare, and the burning-pit flare. Although the three basic designs differ considerably in required capital and operating costs, selection is based primarily on pollution/public relations considerations such as smoke, luminosity, air pollution, noise and spacing factors. Table 1 summarizes the advantages and... 

Plant design differences (primarily in support systems such as cooling water, electrical power, ventilation, and air systems)... 

Initiating events, in this study, initiate plant scram or setback. Other initiators, such as refueling discharge accidents, do not necessarily cause a reactor shutdown but may lead t< minor fuel damage and radioactive releases. The list of initiators for nuclear power plants has litf ance for HFBR because of size and design differences. A list of HFBR-specific initiators was developed from " st prepared with the HFBR staff, the FSAR, the plant design manual, the procedures manual, techn specifications, monthly operating reports, and the HFIR PRA (Johnson, 1988).

A few of these techniques will be reviewed that provide designers different capabilities... 

FIGURE 5.8. A downhill trajectory for the proton transfer step in the catalytic reaction of trypsin. The trajectory moves on the actual ground state potential, from the top of the barrier to the relaxed enzyme-substrate complex. 1, 2, and 3 designate different points along the trajectory, whose respective configurations are depicted in the upper part of the figure. The time reversal of this trajectory corresponds to a very rare fluctuation that leads to a proton transfer from Ser 195 to His 57. 

The above example shows that in designing difference schemes it is very desirable to reproduce the appropriate conservative law on a grid, The schemes with this property are said to be conservative. In subsequent sections the general method for constructing conservative schemes, which are convergent in the class of discontinuity coefficients, will be appreciated. Before we undertake the complete description of this method, it is worth noting two things. 

Actually this way has been demonstrated in Sections 1-3. Several methods find a wide range of applications in designing difference schemes of a desirable quality, among them... 

Let us stress that the integro-interpolational method is a rather flexible and general tool in designing difference schemes relating to stationary and nonstationary problems with one or several spatial variables. 

First of all observe that if scheme (108) or (109) with an operator R is stable, then so is a scheme with an operator R > R Common practice in designing difference schemes involves the development of a scheme which generates an approximation of the attainable order and is economical. With the indicated properties, its stability will be given special investigation.
