Design generalizing

Comparing the overall concentrations of these different carbons designated generally as structural patterns , measured before and after a process such as FCC or hydrocracking (see Chapter 10), enables the conversion to be monitored the simple knowledge of the percentage of condensed aromatic carbon of a feedstock gives an indication of its tendency to form coke. [Pg.69]

Cure Systems of Butyl Rubber and EPDM. Nonhalogenated butyl rubber is a copolymer of isobutjiene with a small percentage of isoprene which provides cross-linking sites. Because the level of unsaturation is low relative to natural mbber or SBR, cure system design generally requites higher levels of fast accelerators such as the dithiocarbamates. Examples of typical butyl mbber cure systems, thein attributes, and principal appHcations have been reviewed (26). Use of conventional and semi-EV techniques can be used in butyl mbber as shown in Table 7 (21). [Pg.241]

Good design generally considers that the streams of liquid should enter onto the top of the packing on 3- to 6-in. [Pg.254]

The term bladed refers to raised, continuous flow restrictors with a standoff distance from the bit body of more than 1.0 in. In most cases cutters are affixed to the blades so that the cutter arrangement may also be described as bladed. The term ribbed refers to raised continuous flow restrictors with a standoff distance from the bit body of 1.0 in. or less. Cutters are usually affixed to most of the ribs so that the cutter arrangement may also be described as ribbed. The term open face refers to nonrestricted flow arrangements. Open face flow designs generally have a more even distribution of cutters over the bit face than with bladed or ribbed designs. [Pg.806]

Radiant power boilers are two-phase boilers. Designs typically employ only one drum for the largest installations, whereas smaller power boiler designs generally incorporate two drums. Fossil fuel-fed, radiant power boilers are probably the most common type of equipment employed for large-scale utility power generation. [Pg.54]

Many boilers are fitted with a heat exchanger-type water sampling coil that permits the collection of a representative and cooled BW sample. The design generally provides for a coil of copper or stainless steel (SS) fitted inside a small SS shell. The unit is fitted with gate valves to control the flow of cooling water and BW. [Pg.93]

The polytropic efficiency is a function of the physical properties of the gas and the machine design. Generally, the higher the feed flowrate, the higher the polytropic efficiency of the compressor. A first estimate of the polytropic efficiency of a centrifugal compressor can be obtained from ... [Pg.274]

To design general area gas detection, each area should be evaluated based on its volume for credible gas release hazards. The factors to consider when determining credible hazards are ... [Pg.249]

These nozzles are available as a single-port or multi-port design. Generally, the single port nozzles are adequate up to 100 kg batch, but for larger size batches a multi-port nozzle such as either a three port (Fig. 10) or six port (Fig. 11) nozzle is required. When these nozzles are air atomized, the... [Pg.277]

Isotypes of hydrogen. The three isotopes,1H. 2H, and 3H. have the names prolium, deuterium, and tritium, respectively. It is to be noted that these names give rise to the names proton, dcuteron, and triton for the cations H. H. 3H . respectively. Because the name proton is often used in contradictory senses, of isotopically pure H ions on the one hand, and of the naturally occurring undifferentiated isotope mixture on the other, the Commission recommends that the latter mixture be designated generally by the name hydron, derived from hydrogen. ... [Pg.1037]
