In case of mixed systems the procedure must be varied and it would be restricted to the special film systems of interest, of course. Mixed systems would be used by inspection companies and industrial users who normally do not dispose of the equipment for measurements as mentioned above. In these cases instead of a round robin test only periodical measurements of the properties of these mixed film systems by an independent third party institution can be used for film classification and continuous surveillance.

The use of scrap tires in industrial faciUties is also a potential growth market. Perhaps the best known user in this category is Archer-Daniels-Midland Company (Decatur, Illinois). Another industrial user, Elexsys (Sauget, Illinois), uses energy derived from its use of IDE as a supplemental fuel to manufacture chemicals used in the mbber industry. 

For by-product coke ovens, it is general practice to blend two or more types of coals that have complimentary technical as well as economic characteristics. Because most by-product coke plants are located near the large industrial users of the coke and by-products, coals usually have to be transported from the coal mines to the coke plants. Thus coal blends are designed on integration of coke quaUty needs, by-product quaUty needs, coal costs, transportation costs, impacts of productivity, and impacts on the coke ovens themselves. The physical behavior of coal blends during coking can damage coke ovens. 

Supercomputers are found in many government research laboratories, intelligence agencies, universities, and a small number of industrial companies. In the United States, the National Science Foundation (NSF) has provided supercomputers to several prominent universities for both academic and industrial users. These centers provide state-of-the-art, supercomputer-tuned appHcations for a wide variety of disciplines, together with staffs who are very knowledgeable in optimization for supercomputer performance. 

Assumes deUvered electricity has one-third of the energy content of the fuel used to produce it ie, 1 Joule of electrical supply to an industrial user represents 3 Joules of fuel consumed. 

Applications Most PHE applications are liquid-liquid seiwices but there are numerous steam heater and evaporator uses from their heritage in the food industry. Industrial users typically have chevron style channel plates while some food apphcations are washboard style. 

Source-Based Effluent Limitations Under the FWPCA, EPA was responsible for establishing point-source effluent hmitations for municipal dischargers, industri dischargers, industrial users of municipal treatment works, and effluent hmitations for toxic substances (apphcable to all dischargers). 

The American Chemistry Council, formerly the Chemical Manufacturers Association (CMA), and the American Institute of Chemical Engineers Center for Chemical Process Safety (AIChE/CCPS) have jointly published Evaluating Process Safety in the Chemical Industry User s Guide to Quantitative Risk Analysis. This is a revised and updated edition of Evaluating Process Safety in the Chemical Industry A Manager s Guide to Quantitative Risk Analysis, published in 1989 by CMA. 

Trace element analysis has become sufficiently important, especially to industrial users, that commercial laboratories specialising in trace and ultratrace elemental analysis are springing up. One such company specialises in high-resolution glow-discharge mass spectromety , which can often go, it is claimed, to better than parts per billion. This company s advertisements also offer a service, domiciled in India, to provide various forms of wet chemical analysis which, it is claimed, is now nearly impossible to find in the United States .

The first step is to identify the substances present at the workplace. As a starting point, knowledge of the process is needed in order to formulate a list of all chemical agents used in the establishment. The list should include not only primary products but also intermediate and final products, as well as reaction products and by-products. For the chemical agents in the list, it is necessary to know their chemical properties, especially hazardous ones their OEL values, including biological limit values and, where these are not available, other technical criteria that can be used to evaluate the risk. It is also helpful to include any information on the safety and health risks of those substances provided by the supplier or other readily available sources. This information on dangerous substances and preparations, in the form of safety data sheets, is intended primarily for industrial users, to enable them to take the measures necessary to ensure the safety and health of workers. 

Even when the time comes to make a purchasing decision, an energy-efficient motor purchase is not a certainty. Sometimes an energy-efficient motor will be the economically efficient choice at other times, not. The capital investment decision is based on the cost in relation to performance, efficiency and reliability. Moreover, the decision depends on the application and the amount of time the motor is in operation. It can be the major component of a product (drill or mixer), or a minor component (computer disk drive) it can be the major component cost of a product (fan), or it can be a minor component cost (stereo tape deck) it can run almost constantly (fan, pump, and machinery), or only a few minutes a day (vacuums and power tools). For example, contractors purchase circular saws almost solely based on performance and reliability. Time is money, and since the saw is operating only a few minutes a day and the contractor is often not responsible for the electricity costs to run the motor, energy efficiency is not a consideration performance and reliability are what matter most. On the other hand, an industrial user, who runs huge electric motors twenty-four hours a day to work pumps, machinery, and ventilation equipment, is very concerned tvitli energy efficiency as well as performance and reliability. 

The purity ot the scrap mainly determines the fraction of energy needed to produce metal from it, and the value of recycling. Clean copper scrap need only be remelted and cast to form recycled copper if the copper is contaminated with organic materials and other metals, more complex separation processes are needed that are similar to production from ores. It is easier to remelt the steel of a car driven in Arizona compared to one rusted by the road salt in snowy areas. Scrap that is produced as a by-product of metal processing can be easily recycled, and it can be collected from relatively few locations. There has been a strong effort to educate both householders and industrial users to separate scrap and return it to waste collectors, leading to a supply of reasonably separated scrap. 

Table 15.2 gives performance data for typical industrial type schemes using thermal power plant in a condensing steam cycle. These do not operate strictly in the simple cycle mode as varying degrees of feed heating are employed. However, overall they convey the basic cycle conditions that the industrial user would encounter and give efficiencies that can be expected.

Whereas the components of (known) test mixtures can be attributed on the basis of APCI+/, spectra, it is quite doubtful that this is equally feasible for unknown (real-life) extracts. Data acquisition conditions of LC-APCI-MS need to be optimised for existing universal LC separation protocols. User-specific databases of reference spectra need to be generated, and knowledge about the fragmentation rules of APCI-MS needs to be developed for the identification of unknown additives in polymers. Method development requires validation by comparison with established analytical tools. Extension to a quantitative method appears feasible. Despite the current wide spread of LC-API-MS equipment, relatively few industrial users, such as ICI, Sumitomo, Ford, GE, Solvay and DSM, appear to be somehow committed to this technique for (routine) polymer/additive analysis. 

Finally, the large number of processors used in many of the parallel simulations cited is striking. It illustrates the enormous progress made in the size of the simulations academic groups have realized. The falling prices of such processors and the ease at which these can be combined into platforms for parallel simulations may have the effect that—just like in the past decade with RANS-based simulations—pretty soon industrial users can afford such dedicated and detailed simulations, both LES and DNS, and can benefit from their outcome in dealing with their commercial targets. 

Substances placed on the market for process-orientated research and development (PORD) are exempt from notification for supply at justified quantities to specified industrial users. The safety data needed for a PORD application varies between the Member States, and may be up to Annex VIIB level (Table 2). PORD exemptions are only valid for 1 year, with the possibility of a 1-year extension. 

Hazard communication to users of dangerous chemical substances and preparations is accomplished by labelling and by means of safety data sheets (SDS), which give more detailed information to industrial users. An SDS has to be provided on request to the public for non-industrial preparations. There is a standard EU 16-heading format (Table 5) specified in the SDS Directive (a. 8).

Economics is the dominant factor in process selection by industrial users. In weighing these economics, capital investments for alternative processes must be obtained on a consistent basis, and operating costs must be calculated using realistic unit costs for such items as electricity and process steam. Perhaps most importantly, the potential markets for the ultimate products from the plant must be accurately assessed. 

In the case of metal cleaning agents these are process auxihaty agents in industrial facilities. Industrial users and manufacturers are the main actors in the substitution process.

By contrast, the industrial user must view any raw material purchase in terms of its cost effectiveness and in the case of rare earth metals this frequently requires the adoption of low purity specifications. Therefore, in the context of the industrial applications to which reference will be made, the term pure will be taken to include all metals having a purity of not less than 95% - the balance being predominately other rare earths. But before considering the applications in detail it is perhaps of value to have some appreciation of the size of the market for these metals.
