Flat plate recovery

A typical ozone system consists of 100 g/hr at a concentration of 1.0 percent to 1.5 percent in air fed to the bottom of bleach collection tanks through ceramic spargers (pore size of approximately 100 t). The system contains air compression and drying equipment, automatic control features, and a flat-plate, air-cooled ozone generator. Regeneration of bleach wastes totaling about 10,000 gallons a year, and recovery of other chemicals can also be cost effective. 

An important application of transpiration cooling is that of plane stagnation flow, as illustrated in Fig. 12-8. Solutions for the influence of transpiration on heat transfer in the neighborhood of such a stagnation line have also been worked out in Ref. 3, and the results are shown in Fig. 12-9. As would be expected, gas injection or suction can exert a significant effect on the temperature recovery factor for flow over a flat plate. These effects are indicated in Fig. 12-10, where the recovery factor r is defined in the conventional way as...

The heat recovery heat exchanger is of flat-plate type Fig. 9). This construction was selected because of the low investment costs. Primary flow is moist, nearly saturated exhaust air from the drying silo, The secondary flow is outdoor air, which is used as combustion air and drying air.

There has been a move from conventional granular gel materials to foamed (198) and flat plate (199) type superabsorbents based on poly(acrylic acid). In addition to superabsorbents for personal hygiene, the materials have wide ranging applications in many areas from biomedical to cosmetics. Some of these are petroleum recovery and sealing of sewer pipes when cross-linked with metals such as iron salts (200) flocculants in water purification (201) copolymers with...

Cassette Cassette products are widely used in the biopharmaceutical industry and specifically dominate the protein concentration purification market due to their compactness, which provides excellent product recovery capabUity. Cassette modules contain presealed flat sheet membranes separated by feed and filtrate spacers. This is an improved design compared to earher plate and frame configurations, making installation and replacement much easier and more reliable for the end user (shown in Figure 14.5). 

MicroChannel plate detectors are particularly useful in time-of-flight mass spectrometry, as they are flat, minimizing time spread and subsequent mass resolution of homologous ion packets. In addition, they have reasonable gain (104—107 per plate) and fast response time (100-psec time resolution). The major limitation of multichannel plate detectors is the recovery time needed for the detector to rechaige. When a channel is discharged, a recovery time on the order of 10 nsec is typical. This becomes problematic if an ion follows another into a particular...

If the surface is not flat and or accessible, a swab has to be used. This is a small wad of cotton on the end of a short rod, see Fig. 31.2. First this has to be wetted with sterile water. After that it can be swabbed onto the surface to be examined and finally it has to be wiped across an agar medium in a petri dish. The recovery from a contact plate is 30-50 % and from a swab around 10 % [24].
