Building full-scale

A modular 250-MW reactor of this type could be constructed off-site and then shipped by truck or train. This could shorten construction time by 2 years with corresponding cost savings. China and South Africa plan to build full-scale prototypes. 

Scale model experiments (.Section 12.4) In the case where there is no site to carry out full-scale measurements (planning phase), or it would be too expensive or space-demanding to construct a full-scale experiment (large lacdities/rooms/buildings). 

The coefficients Cp will vary across each surface of the building and, except for very simple shapes, can only be found by model or full-scale test. Since the coefficients will change with wind direction, complete calculation of wind-induced ventilation is very unwieldy, needing computer analysis. 

The ultimate test, short of constructing a full-scale unit, is to build a small-scale system in which each item to be incorporated in the final device is represented. Such programmes are too specialised to warrant discussion here, and are fully described in the literature... 

Revise the model and build the full-scale plant. 

In 1999, the European Council of Vinyl Manufacturers (ECVM) chose this process as the most robust and economical, and started to support it within the context of ECVM s recycling efforts. ECVM committed 3 million as a support to the building of a pilot plant. The pilot will be build at Solvay s Tavaux plant, located in the eastern part of Erance. If the pilot is successful, most probably a 25,000 tpa full scale plant will be build. However, it is not expected that such a full scale plant will be operational before 2005. 

Resident Time Distribution (RTD) is widely employed in the chemical engineering industry, as an analytical tool for characterizing flow dynamics within reactor vessels. RTD provides a quantitative measure of the back-mixing with in a reactor system [2]. However the cost and time involved in building and operating a pilot- or full scale reactor for RTD analysis can be economically prohibitive. As such we have implemented a numerical RTD technique through the FLUENT (ver. 6.1) commercial CFD package. 

National programs are underway to develop and deploy the reactor and applications in China, France, South Korea, and United States [35-38]. Many more countries are participating in R D through the High Temperature Reactor Technology Network of the European Union [39] and the GIF including the 10 member countries [40]. Builds of full-scale commercial demonstration reactors are actively planned in several countries such as South Africa [41] and the United States [38]. 

Note that this index only produces a relative number. Two products with widely different values of the index might be equally safe if, in fact, neither impedes escape. Conversely, two products with apparently similar values may produce different hazard levels if both products are close to the margin of safety. Thus, the scale for any index must be "calibrated", and it may well be different for each building or type of occupant. Generally, this will require a more complete hazard analysis and/or full-scale fire tests. Protocols for doing this are currently under consideration. 

Titan Wood limited was formed in April 2003, by Accys Chemicals PTC, a UK-based company. The company is in the process of building a full-scale production facility for the acetylation of solid wood located at Arnhem in The Netherlands, which will become operational at the end of 2005. The company acquired equipment and intellectual property owned by the former AKBV, based in Arnhem. AKBV developed a pilot plant acetylation reactor of 2 300 litre capacity, 85 cm in diameter and 4 m long, capable of acetylating 0.9 m of solid wood per batch. 

Full-scale operation costs were compared for the Brayton cycle at varying VOC concentrations. The unit costs for VOC recovery are compared in Table 2. The total capital required is 156,173. This price encompasses the equipment costs, including building, site preparation and freight, and capital costs, which include design, inspection, and management (D14334A, p. 64). 

Encouraged by the operating success so far of a pilot plant in Lyons, PCUK is building a small-scale commercial unit there due on stream in 1975- A full scale plant is planned for 1977... 

Although the tunnel test is widely accepted, conditions and orientations involved are not those normally found in installed insulations. New laige-scale tests have been developed the results can be taken to represent actual performance more closely. Such tests include the International Conference of Building Officials (ICBO) and ASTM E603 full-scale room tests, ASTM E108 roofing test, the UL roof deck construction test, the Factory Mutual Calorimeter Test, and both alaige- and small-scale comer test. 

Two aspects of scaleup frequently arise. One is building a model based on pilot plant studies that develop an understanding of the process variables for an existing full-scale mixing installation. The other is taking a new process and studying it in the pilot plant in such a way that pertinent scaleup variables are worked out for a new mixing installation. 

The goal of the EDS coal liquefaction project is to develop the process to a state of commercial readiness. This means that the technology should be available at the end of the project to design and build a full-scale, pioneer commercial plant with a reasonable and acceptable level of risk. 

Testing codes within the scenario of a fully developed fire are based on intermediate, large, or full-scale testing. Specimens are typically in the dimension of several square meters and often, real components such as building columns are tested, or the whole product in the case of gas bottles. Tests like the small-scale test furnace based on specimens of 500 mm x 500 mm are exceptions. Intensive flame application or the use of furnaces realizing standard time-temperature curves are used to simulate the characteristics of fully developed fires. Thus, in particular the heat impact of convection and the surface temperature are clearly greater than in the tests discussed earlier. The fire properties investigated are often resistance to fire, or the fire or temperature penetration.
