Nozzle system

Provide a means of filling the tank to operating level prior to operating the blending nozzle system. Damage could result from discharging the high velocity jet into an empty tank. 

Figure 1. Blending can be improved by a shrouded blending nozzle system because the jet nozzle educts a large quantity of surrounding fluid.

The room airflows are controlled mainly by the supply or/ md circulation air jets using, for example, concentrated jets, ceiling air supply, or high-impulse nozzle systems. Examples of different methods are illustrated in Fig. 8.14. 

An efficient feed injection system produces extremely small droplets that vaporize quickly. Rapid vaporization minimizes the amount of non-vaporized hydrocarbons that block the active sites. An effective feed nozzle system must instantaneously vaporize and crack asphaltenes and polynuclear aromatics to lower boiling entities.

These processes are very rapid and allow the preparation of inorganic supports in one step. This technique allows large-scale manufacturing of supports such as titania, fumed silica, and aluminas. Sometimes the properties of the material differ from the conventional preparation routes and make this approach unique. Multicomponent systems can be also prepared, either by multimetallic solutions or by using a two-nozzle system fed with monometallic solutions [22]. The as-prepared powder can be directly deposited onto substrates, and the process is termed combustion chemical vapor deposition [23]. 

Both a pneumatic heated nozzle system [487] and an ultrasonic nozzle/vacuum system [699] have been described for removing the troublesome solvent in order to simplify IR analysis. The former system (LC Transform ) has been commercialised [700], and allows full use of the mid-IR spectral range by providing analyte films free from solvent interference. The evaporative...

High Productivity Also called HP. An improved method of operating gas-phase plants for making polyethylene. It involves removing gas and liquid from the fluidized bed, separating them, and returning the liquid to the bed via a patented nozzle system. Developed by BP in 1994 and operated in its Grangemouth refinery since 1995. See also Supercondensed Mode. Chem.Br, 1995,31(4), 278. 

For many years electron bombardment has been most commonly used for heating the nozzle . During the last five years a very convenient, so-called radiation nozzle system has been developed This system is illustrated in Fig. 3. 

The radiation nozzle system has been used for studying a series of transition metal dihalide molecules. Typical molecular intensity distributions are shown in Fig. 4 for manganese(II) chloride. The quickly damping character of the intensity distribution relates to the large-amplitude motion in the molecule due to the high temperature ( 750 °C) conditions of the experiment. Fig. 5 shows the radial distribution from the same experiment which also well demonstrates the straightforward manner of structure determination of such simple molecules.

Application of these chemicals in portable or wheeled extinguishers, hand-held hose line systems or fixed nozzle systems provides for quick fire knockdown and extinguishment. 

For scrubbing of sulfur dioxide and a large portion of catalyst fines, a countercurrent spray tower with a multiple stage nozzle system is typically applied. The WESP is applied after the scrubber section to remove the residual particulate matter with a... 

The top spray system has been used to coat materials as small as 100 microns. Smaller substrates have been coated, but agglomeration is almost unavoidable due to nozzle limitations and the tackiness of most coating substances. Batch sizes range from a few hundred grams to approximately 1,500 kg. Typically, a single nozzle wand with up to six liquid delivery ports is used, but multiple nozzle systems have been applied. 

A typical DP cell is shown in Fig. 6.19a<23). The associated flapper/nozzle system works on a force-balance principle (see Volume 1, Section 6.2.3). The output pressure P0 is linearly related to the difference in pressure (P, - P2), thus ... 

One important application of pneumatic transmission is in the operation of diaphragm actuators. These are the elements generally employed to drive the spindles of control valves (Section 7.22.3) and, if hard-wired transmission systems are employed, require devices which convert electric current into air pressure or air flowrate, i.e. electropneumatic (E/P) converters. The basic construction of a typical E/P converter is illustrated in Fig. 6.77. A coil is suspended in a magnetic field in such a way that when a current is passed through the coil it rotates. This rotation is sensed by a flapper/nozzle system (Section 7.22.1). The nozzle is supplied with air via a restrictor and its back pressure actuates a pneumatic relay. The output from the latter is applied to the feedback bellows and also acts as output from the E/P converter. Electropneumatic valve positioners employ the same principle of operation. 

Thus, the pressure of the output to the valve P is the sum of Pi and the pressure produced by the wide-band proportional action contributed by the proportional bellows and the flapper-nozzle system (cf. equation 7.3). Note that for t > 0, P/ is no longer equal to P0 and thus equation 7.268 only strictly applies at t = 0. The value of 3 i (and consequently r/) depends upon the capacity C/B of the integral bellows and the the resistance to flow R/r through the integral restrictor. It is generally assumed that C/fi changes little and r/ is varied by adjusting R/r.
