Basicity difference

Good design ideas for new plants are also good for existing plants, but there are three basic differences. (/) Because a plant already exists, the capital—operating cost curve differs. Usually, this makes it more difficult to reduce utiHty costs to as low a level as in a new plant. (2) The real economic justification for change is more likely to be obscured by the plant accounting system and other nontechnical inputs. (2) The real process needs are... [Pg.93]

The basic difference between a bent shaft and a deflected shaft is the following. A bent shaft spinning inside close tolerances leaves a scratch mark around the eireumferenee of stationary elements corresponding to a damaged spot on the shaft. A deflected shaft. spinning within close... [Pg.134]

Classes II and III include all tests in which the specified gas and/or the specified operating conditions cannot be met. Class II and Class III basically differ only in method of analysis of data and computation of results. The Class II test may use perfect gas laws in the calculation, while Class III must use the more complex real gas equations. An example of a Class II test might be a suction throttled air compressor. An example of a Class III test might be a CO2 loop test of a hydrocarbon compressor. Table 10-4 shows code allowable departure from specified design parameters for Class II and Class III tests. [Pg.418]

The basic difference between this type of valve and the normal external loop sample valve is the incorporation of an extra port at the front of the valve. This port allows the injection of a sample by a syringe directly into the front of the sample loop. Position (A) shows the load position. Injection in the front port causes the sample to flow into the sample loop. The tip of the needle passes through the rotor seal and, on... [Pg.293]

There are some basic differences between toxic and allergic reactions. The most important differences are (1) an allergic reaction always requires a prior exposure to the compound, and this reaction only occurs in sensitized individuals and (2) a dose-response relationship is characteristic to a toxic reaction, whereas such a relationship is much less clear for an allergic reaction. Even minute doses can elicit an allergic reaction in a sensitized individual (see Fig. 5.42). ... [Pg.276]

JOM(400)149 96BSCF33]. The complex 164 is the first known t] -phospholyl species. The tungsten atoms have a coordination number of 9, and the carbon atoms of the phospholyl ring are coplanar. The phosphorus atom deviates from the plane of carbon atoms by 0.015 nm. The basic difference between the Ti -cyclopentadienyl and ri -phospholyl complexes is the existence of a low-lying LUMO localized mainly at the phosphorus atom. [Pg.145]

In what follows the degree of order of the hexagonal phases in Cases 1-6 will be compared to see whether there are basic differences between them. For this purpose the heats of fusion for the hexagonal phases... [Pg.302]

The slip for this type of compressor is similar to that of the lobe units however, the passages are basically different, and this changes the approach to slip correction. The manufacturer should be consulted for data specific to a particular unit. The slip is dependent on the pressure differential across the unit and the gas density. It does not vary with speed or length of the rotor. [Pg.526]

This basic difference equation - known as the Schema Theorem [holl92] - expresses the fact that the sample representation of schemas whose average fitness remains above average relative to the whole population increases exponentially over time. As it stands, however, this equation addresses only the reproduction operator, and ignores effects of both crossover and mutation. [Pg.591]

It is remarkable that the magnitude of trapping is comparable to that in a system devoid of disorder. In fact, the critical concentration above which the effect of traps becomes noticeable is the same, i.c. In c, EJkT, which follows from Eq. (12.17). The basic difference between a disordered and a disorder-free system is... [Pg.524]

Cellulose is an important part of woody plants, occurring in cell walls and making up part of the structural material of stems and trunks. Cotton and flax are almost pure cellulose. Chemically, cellulose is a polysaccharide—a polymer made by successive reaction of many glucose molecules giving a high molecular weight (molecular weight ->- 600,000). This polymer is not basically different from the polymers that were discussed in Section 18-6 ... [Pg.425]

There are two basic differences of (sic) free atoms and chemically bound atoms. First, the more diffuse an AO, the stronger it is perturbed in molecular and condensed matter. The (n + )s AOs of the transition metal atoms, especially of the earlier ones, are not of primary importance for chemical bonding. Their relevance is comparable to that of the diffuse orbitals of main group elements ([34], p 653). [Pg.138]

Depending on which of the products, caldum gluconate, sodium gluconate or gluconic add (free add) is required, die fermentations have some basic differences. [Pg.144]

In the second half of the 1960s, at the same time but independently, three basically different plastic separators were developed. One was the polyethylene separator [16] already referred to in starter batteries, used only rarely in stationary batteries, but successful in traction batteries. The others were the microporous phenolic resin separator (DARAK) [18] and a microporous PVC separator [19], both of which became accepted as the standard separation for stationary batteries. They distinguish themselves by high porosity (about 70 percent) and thus very low electrical resistance and very low acid displacement, both important criteria for stationary batteries. [Pg.254]

Basic difference Melt streams brought together outside die body (between extruder and die) and flow through the die as a composite Each melt stream has a separate manifold each polymer spreads independently of others they meet at die pre-land to die exit... [Pg.480]

As esters of sulfuric acid, the hydrophilic group of alcohol sulfates and alcohol ether sulfates is the sulfate ion, which is linked to the hydrophobic tail through a C-O-S bond. This bond gives the molecule a relative instability as this linkage is prone to hydrolysis in acidic media. This establishes a basic difference from other key anionic surfactants such as alkyl and alkylbenzene-sulfonates, which have a C-S bond, completely stable in all normal conditions of use. The chemical structure of these sulfate molecules partially limits their conditions of use and their application areas but nevertheless they are found undoubtedly in the widest range of application types among anionic surfactants. [Pg.224]

Interactive LC systems are those where solute retention is predominantly controlled by the relative strengths of the molecular interactions between solute molecules with those of the two phases. In such systems, exclusion and entropically driven interactions will be minor contributions to retention. The three basically different types of molecular interaction, dispersive, polar and ionic give rise to three subgroups, each subgroup representing a separation where one specific type of interaction dominates in the stationary phase and thus governs solute retention. The subgroups are as follows ... [Pg.296]

Two basically different reactor technologies are currently in operation low temperature and high temperature. The former operates at -220 °C and 25-45 bar, employing either a multitubular, fixed bed (i.e. trickle bed) reactor or a slurry bubble column reactor with the catalyst suspended in the liquid hydrocarbon wax product. [Pg.325]

In this section, we will present the basis developed to explain the structure of solids. That is, the concepts that were perfected in order to accurately describe how atoms or ions fit together to form a solid phase. This work was accomplished by many prior workers who established the rationale used to define the structure of a symmetrical solid. As you will recall, we said that the basic difference between a gas, liquid and that of a solid lay in the orderliness of the solid, compared to the other phases of the same material. [Pg.31]

There is very little basic difference in the procedures for joining tubes of different sizes and for joining tubes of the same size. The main difference lies in the preparation of the end of the larger tube the end of this tube should be drawn down to a spindle and the spindle cut off in the flame. The closed end so produced should be heated locally so that vslien it is blown out the hole produced will be of the same size as the bore of the smaller tube. But it is usually better to... [Pg.37]

Nucleus Growth The basic difference between reactions producing a new crystalline phase and reactions producing a gas or liquid phase is the step of nucleus growth. Difficulties exist in the incorporation of primary reaction products into the lattice. [Pg.258]

The basic difference between the two pathways resides in the fate of the 0-0 bond in the original oxygen molecule, which in the first pathway is broken in the initial reaction step. The resulting oxygen atoms are adsorbed on the electrode and then are reduced electrochemically ... [Pg.276]

Various options for the production of tantalum from pure tantalum compounds are summarized in Figure 4.26. The oxide and halide reduction reactions described above have been carried out in basically different types of reactors, using processes that are characteristically different because the forms and the physico-chemical nature of the feed materials are different. A relatively recent development with regard to process metallurgical equip-... [Pg.425]
