The other space-saving approach is to use the Kobe (Kobe Steel) type of channel enclosure, which does not have all the external head bolts of typical TEMA Type B or Type C head enclosures. These exchangers require special tools to remove the tube bundles and trained maintenance personnel to do the work. These exchangers should never be located in stmctures because of the need to be able to access the channel from grade as it is difficult to remove the channel cover plate by using special equipment.

FIGURE 35.18 Example of a two-wing (tangential) rotor (2WS rotor of Kobe Steel Ltd). 

Kobe Steel reported two rotor developments. The first development is an improvement of the four flight rotor by extending the long rotor wing until four times the short rotor wing (see Figure 35.23). As for the ST rotor it can be mn in an even speed or with friction. The performance improvement can...

FASTMET A DR process, using pulverized coal and iron ore fines, heated in a rotary hearth furnace. Under development by Midrex Corporation and Kobe Steel from 1991 apilot plant was operated by Kobe Steel in Japan in 1996. 

ITmk3 [mark 3 indicates that this is a third generation ironmaking process, marks one and two being the blast furnace and direct reduction] A modification of the Fastmet process, for making molten iron. Pelleted iron ore fines are reduced with a solid reductant. The iron in the reduced pellets separates as molten metal, uncontaminated by gangue. Developed in 1996 by Midrex Corporation and Kobe Steel. Commercialization is expected in 2003. 

MOLPSA-nitrogen [Molecular sieve pressure swing adsorption] A version of the PSA process for separating nitrogen from air, developed by Kobe Steel. Most PSA processes for nitrogen use molecular sieve carbon as the adsorbent, but this one uses zeolite X. Water and carbon dioxide are first removed in a two-bed PSA system, and then the nitrogen is concentrated and purified in a three-bed system. 

SPIREX A DR process for making iron powder or hot briquetted iron from iron ore fines. Three stages are used. The first is a circulating fluidized bed preheater whose turbulent conditions reduce the particle size of the ore. The second and third stages achieve the reduction in fluidized beds, fed by reducing gases from a MIDREX reformer. Developed by Midrex Direct Reduction Corporation and Kobe Steel. A demonstration plant was scheduled to be built at the Kobe Steel plant in Venezuela in 1997.

Other common continuous mixers involve substantial modification of single and twin screw extruders, aimed at improving distributive mixing capability in particular, and leading to the development of continuous mixers such as the Transfermix (50) and the Buss Ko-Kneader (51). Another approach in continuous mixer development is to transform batch mixers into continuous ones. Thus, the roll-mill can be converted into a continuous mixer by feeding raw material on one side and continuously stripping product on the other side. In addition, the Banbury mixer was imaginatively transformed into the Farrel Continuous Mixer (FCM) by Ahlefeld et al. (52), and, later, two similar continuous mixers were developed by Okada et al. (53) at Japan Steel Works and by Inoue et al. (54) at Kobe Steel.

FASTMET A DR process, using pulverized coal and iron-ore fines, heated in a rotary hearth furnace. Under development by MIDREX Corporation and Kobe Steel from 1991 a pilot plant was operated by Kobe Steel in Japan in 1996. The first commercial installation was at Kobe Steel s Kakogawa plant in Japan in 2000. Further development of the process took place under the name ITmk3. A variation, known as FASTMELT, conveys the hot iron powder to an adjacent melter. See also MIDREX. 

UBC [Upgraded Brown Coal] A process for upgrading brown coal for use in power plants. The pulverized coal is mixed with light petroleum and asphalt and heated to >140°C, which expels the water and solvent, leaving a porous material containing asphalt in the pores. This material is briquetted and is then suitable for use in a power plant. Developed by Kobe Steel from 1993, piloted in Indonesia in 2004, and expected to be commercialized in 2012. 

Vinyloop A process for recycling polyvinyl chloride (PVC). Used PVC is ground, dissolved in a proprietary solvent, and reprecipitated in a granular form. Developed by Solvay in 1999 and first commercialized by a joint venture at Ferrare, Italy. The first plant, at Ferrare, was opened in 2004. A joint venture between Solvay and Kobekci Eco-Solutions (a subsidiary of Kobe Steel), VINYLOOP, was formed to commercialize the process in Japan its plant opened in 2006.

Fluidized sand beds are surprisingly insensitive to the unit size of the feed material. Pieces of scrap tires up to a weight of 2.7 kg each were fed and quantitatively pyrolyzed. These results offer the perspective for a pyrolysis process for scrap tyres without prior size reduction. Most pyrolysis processes use feed crushed to a 200-20 nun size which involves considerable expense [9], Successful pyrolysis experiments in an indirectly heated rotary kiln have been conducted by Kobe Steel [3].
