Processing rate

Nonwoven Cards. Modem, high speed cards designed to produce nonwoven webs show evidence of either a cotton or wool fiber-processing heritage and have processing rate capabiUties comparable to those of gametts. Contemporary nonwoven cards are available in widths up to 5 m and are configured with one or two main cylinders, roUer or stationary tops, one or two doffers, or various combinations of these principal components. [Pg.149]

Heat transfer and mass transfer occur simultaneously whenever a transfer operation involves a change in phase or a chemical reaction. Of these two situations, only the first is considered herein because in reacting systems the complications of chemical reaction mechanisms and pathways are usually primary (see HeaT-EXCHANGETECHNOLOGy). Even in processes involving phase changes, design is frequendy based on the heat-transfer process alone mass transfer is presumed to add no compHcations. But in fact mass transfer effects do influence and can even limit the process rate. [Pg.95]

Rubber Chemicals. Sodium nitrite is an important raw material in the manufacture of mbber processing chemicals. Accelerators, retarders, antioxidants (qv), and antiozonants (qv) are the types of compounds made using sodium nitrite. Accelerators, eg, thiuram [137-26-8J, greatly increase the rate of vulcaniza tion and lead to marked improvement in mbber quaUty. Retarders, on the other hand (eg, /V-nitrosodiphenylamine [156-10-5]) delay the onset of vulcanization but do not inhibit the subsequent process rate. Antioxidants and antiozonants, sometimes referred to as antidegradants, serve to slow the rate of oxidation by acting as chain stoppers, transfer agents, and peroxide decomposers. A commonly used antioxidant is A/,AT-disubstituted Nphenylenediamine which can employ sodium nitrite in its manufacture (see Rubber chemicals). [Pg.200]

Continuous free flow electrophoresis has been used for the separation of biopolymers (e.g. ovalbumin and lysozyme) [20] as well as smaller inorganic species (e.g. [Co sepulchrate)] and [Co (CN)g] ) [21]. Sample processing rates of 15 mg h were reported for a mixture of Amaranth (MW 804) and Patent Blue VF (MW 1159) [22]. [Pg.294]

In a different approach, Stalcup and co-workers [25] used sulfated (3-cyclodextrin for the enantioseparation of piperoxan in work directly derived from earlier CE and classical gel results. Their results were obtained using a continuous free flow apparatus developed by R S Technologies, Inc. Processing rates on the order of 4.5 mg h were reported. [Pg.294]

No overlap. Data trace update rate is the same as the block processing rate. This rate is governed by the physical requirements that are internally driven by the frequency range of the requested data. [Pg.717]

This represents a special case of high-level turbulence at a surface by the formation of steam and the possibility of the concentration of ions as water evaporates into the steam bubbles . For those metals and alloys in a particular environment that allow diffusion-controlled corrosion processes, rates will be very high except in the case where dissolved gases such as oxygen are the main cathodic reactant. Under these circumstances gases will be expelled into the steam and are not available for reaction. However, under conditions of sub-cooled forced circulation, when cool solution is continually approaching the hot metal surface, the dissolved oxygen... [Pg.328]

In a later publication, Kolbel et al. (K16) have proposed a less empirical model based on the assumption that the rate-determining steps for a slurry process are the catalytic reaction and the mass transfer across the gas-liquid interface. When used for the hydrogenation of carbon monoxide to methane, the process rate is expressed as moles carbon monoxide consumed per hour and per cubic meter of slurry ... [Pg.84]

Kinetic models developed for reactor scale-up are also suitable for reactor optimization. The development of detailed kinetic models accounting for all factors influencing process rates is a time-consuming task. Therefore, more empirical simplified models are often used for simulation and optimization of existing reactors. [Pg.318]

Mass transfer-limited processes favour slurry reactors over monoliths as far as the overall process rates are concerned. Moreover, slurry reactors are more versatile and less sensitive to gas flow rates. However, the productivity per unit volume is not necessarily higher for slurry reactors because of the low concentration of catalyst in such reactors. There also is no simple answer to the selectivity problem, and again, each process should be compared in detail for both reactors. [Pg.397]

The size requirements of a semicontinuous unit k for product i are characterized by duty factors Dik whose physical meaning is similar to the size factors, and the processing rates Rk the duty factor is related to the processing time for semicontinuous equipment as follows ... [Pg.462]
