Effects capturing

In conventional treating systems using cold-gas cleanup, the small fraction of metals released to the gas phase is captured effectively in the gas cooling and gas treating steps. The combination of gas cooling and multistage gas—Hquid contacting reduces very substantially the potential for airborne emissions of volatile metals such as lead, beryUium, mercury, or arsenic. [Pg.275]

An exhaust airflow rate lower than q results in reduced contaminantcapturing effectiveness. An exhaust airflow rate greater than q g results in excessive capturing effectiveness (Fig. 7.81). [Pg.542]

An increase of the capture airflow rate normally results in increased capture efficiency, but the relationship between these quantities is not linear. A case-by-case evaluation is necessary to establish this relationship. In every case an increase of the airflow rate causes an increase of the operating costs. Analogously, a decrease in airflow rate leads to a decrease in capture efficiency and in some cases, a total breakdown of the capture effect (e.g., capture dev ices working with the vortex principle require minimum airflow rates). [Pg.880]

First, a number of calculations are run without the above four features ( ) in place (program lines 40, 110-130) to verify the rest of the program. Next, each of the features is introduced individually to capture effects, if any. [Pg.232]

Self-shadowing and resonance capture effects. The use of small samples and standards so that the neutron flux is not appreciably attenuated between the exterior and interior of the irradiation unit is to be desired. When large samples are used or appreciable high cross section material is present in the matrix, it is important that the standard be prepared with a matrix physically and chemically similar to that of the sample. [Pg.62]

Although Sn = 7-9 MeV for most stable nuclei, its value falls to Sn = 2-3 MeV after 10 to 20 neutron captures, depending on the element When it does so, the captures effectively cease, because the ejection of the next neutron by photons is even faster than the rate of neutron captures. This location is called a waiting point because the series of captures must then wait until beta decay has been able to transmute the nucleus to the next higher element, for which the neutrons will have greater binding. The waiting point concept was important to the development of the theory of the r process. [Pg.304]

The dilution of crude feedstock can, however, be very critical when the antibody is present in low amount, it increases the loading volume of the column and consequently the loading time it also decreases the ability of the column to capture effectively the antibody due to unfavorable conditions for a proper ion exchange interaction. [Pg.563]

Last, but not least, there is the financial risk. The R D costs are high and can exceed USD 100 million for a single iruiovative biotech-based product In addition, in order to ensure that value is captured effectively, expensive downstream acquisitions may be necessary. So why would anyone be wiUing to invest in this technology ... [Pg.67]

The use of °Kr and Kr to arrive at P fP s (Equation (12)) is unsatisfactory for samples that contain appreciable amounts of Br, from which neutron capture produces °Kr and Kr, but not Kr. To avoid this problem, PsfPss has often been calculated from an empirical relation obtained by selecting samples with negligible neutron capture effects and then regressing calculated values of PsfP 3 (from Equation (12)) on directly measured values of Kr/ Kr (Marti and Lugmair, 1971). The regression gave... [Pg.352]

While these potentials are notationally complex, they are conceptually simple in terms of the basic physics they incorporate. In particular, potentials of this type invoke both of the new physical ideas presented in this section environmental dependence and angular forces. In particular, the quantity denoted bij guarantees that the interaction between two given atoms will depend upon both the number and disposition of neighboring atoms. For our purposes, the key advantage of the Tersoff potential is its attempt to capture effects which are outside of the purview of more traditional potentials. [Pg.175]

Thus, the decrease of the capture effectiveness caused by the interlayer stabilisation is expressed by... [Pg.484]

I remember back in the 1960s, when the AT T Picturephone was first developed. The mathematicians did a study of the rate at which the market would adopt the Picturephone, and they predicted a curve that was very much like Metcalfe s Law. They modeled it after the spread of the plague. The idea is that you don t want to be the first person on your block to get the plague. But when all your friends get it, you think about getting it. The more people have it, the more you re likely to get it, and suddenly there is this capture effect, where everybody has it. This law of network externality governs so much of the business and is at the heart of the Microsoft trial. Why does Microsoft have a monopoly Is this a natural phenomenon that has to do with networks ... [Pg.112]

According to this definition, Damkohler number gives the ratio of the characteristic process time to the characteristic reaction time (Doherty and Malone, 2001) and captures effectively the major dependence of conversion, production rate and product purities on the feed flowrate, catalyst level and holdup (Chen et al., 2002). For an open... [Pg.24]

Location-dependent carrier sensing. Because the signal strength decays with distance according to a power law, only nodes within a specific range are able to communicate. This gives rise to the hidden and exposed terminals and the capture effect, as described next. [Pg.2102]

The U.S. Clean Air Act Amendments of 1990 listed 189 substances as hazardous air pollutants, of which 37 substances have been detected in power plant emissions [1]. Of the 37 hazardous air pollutants, 11 are trace metals such as mercury. It is of greatest concern because of the perceived risks from its environmental release, it occurs mainly in the vapor form, and because is not captured effectively by existing particulate removal systems. [Pg.459]
