Single-cylinder reactor

In the range of the flue gas flow rate from 0.5x10 to 1,5xKf nv -s-1, the sulfur-removal efficiency obtained in the reactor of a single cylinder drops slightly as the flue gas flow rate increases, while in the reactor of two co-axial cylinders this efficiency is essentially independent of the flue gas flow rate. 

In the comparative experiments the reactor with two co-axial cylinders exhibits obviously higher sulfur-removal efficiency than that of a single cylinder. 

Turning to cross flow over bundles of tubes with surface roughness, some work has been done in the context of heat exchanger development for gas-cooled reactors and conventional shell-and-tube heat exchangers. This work is backed up by extensive studies of single cylinders, such as those with pyramid roughness elements tested in air by Achenbach [82]. Nusselt... 

The entire QSL process takes place in a single reactor as shown in Figure 6 (15). The reactor consists of an almost horizontal, refractory-lined cylinder, which can be tilted by 90° when operation is intermpted. Concentrates, fluxes, recirculated flue dust, and normally a small amount of coal, depending on the type of concentrate, are pelletized. The pelletizer ensures that the raw materials are mixed to the required degree of uniformity. 

Robinson and Walsh have reviewed earlier cell designs. The performance of a 500 A pilot plant reactor for copper ion removal is described. Simplified expressions were derived for mass transport both in single pass [243] and batch recirculation [244]. For a detailed discussion of the principle and the role of the rotating cylinder electrode reactor in metal ion removal the reader is referred to Refs. [13] and [241] (46 references).

Note the different ds in these problems. While d always signifies diameter, D is reactor diameter (or diameter of a cylinder or sphere because that notation is used in mass transfer rather than the radius R), dp is the diameter of a single pore, and d is the diameter of a single tube in a tube waU reactor. 

As with neutron powder methods, both monochromatic and time-of-flight (Laue) techniques have been used for single-crystal neutron studies. Such studies are much less numerous, however, as a result of the difficulty of compressing suitably sized (>1 mm ) single-crystal sample to the required pressure while maintaining the crystal quality. The piston cylinder cell design of Me Whan and others [128] has been used at the ILL reactor source for a number of neutron structural studies to... 

Fixed-bed reactors consist of one or more tubes packed with catalyst particles and operated in a. vertical position. The catalyst particles may be a variety of sizes and shapes granular, pelleted, cylinders, spheres, etc. In some instances, particularly with metallic catalysts such as platinum, instead of using single particles, wires of the metal are made into screens. Multiple layers of these screens constitute the catalyst bed. Such screen or gauze catalysts are used in commercial processes for the oxidation of ammonia and the oxidation of acetaldehyde to acetic acid.

A rotating cylinder electrochemical reactor (RCER) for electrodeposition can be a single cell or as a cascade of cells (see Figure 11.4) on a common rotating shaft. 

The turbine K-160-4.2 consists of a single - flow high pressure cylinder, and double-flow low pressure cylinder that exhausts to the condenser. The two moisture separator/ reheaters are integrated in the main turbine system. The reactor plant is combined with one turbine generator designed for base load and load-following operation. 

In the first version of this design a relay system is used to operate a 2oo3 voting function leading to a single channel actuation. The trip actuation uses a solenoid valve and to vent the air cylinder on a valve that will drive open and release quench water into the reactor. A single channel version of the analysis model is shown in Diagram 2.
