The electrowinning process developed by Ginatta (34) has been purchased by M.A. Industries (Atlanta, Georgia), and the process is available for licensing (qv). MA Industries have also developed a process to upgrade the polypropylene chips from the battery breaking operation to pellets for use by the plastics industry. Additionally, East Penn (Lyons Station, Pennsylvania), has developed a solvent-extraction process to purify the spent acid from lead—acid batteries and use the purified acid in battery production (35). 

Knowledge of these types of reaetors is important beeause some industrial reaetors approaeh the idealized types or may be simulated by a number of ideal reaetors. In this ehapter, we will review the above reaetors and their applieations in the ehemieal proeess industries. Additionally, multiphase reaetors sueh as the fixed and fluidized beds are reviewed. In Chapter 5, the numerieal method of analysis will be used to model the eoneentration-time profiles of various reaetions in a bateh reaetor, and provide sizing of the bateh, semi-bateh, eontinuous flow stirred tank, and plug flow reaetors for both isothermal and adiabatie eonditions. 

Very low molecular weight polypropylenes are now known to be useful industrial additives (8). Such polymers can be made by using very high concentrations of peroxide in the degradation. Extension of the model to high initiator concentrations is therefore of practical interest, o The model was found to be sensitive to step size in reaction time used. 

Monographs dealing with SFC applications have appeared [304,342]. In spite of all the various advertised advantages, SFC techniques take a long time to take off in industrial additive analysis (cf. Table 1.13). Few robust SFC applications were developed. 

Optimisation of software (generic format) would be auspicious, but even no generally accepted norms are available. Specialised MS, FTIR and ToF-SIMS computer-based industrial additive libraries are the necessary support for analytical developments. Web-based data mining tools are also starting to become available.

Normally, after being heated, these streams are used in the boiler area (deaerator feedwater, cold return condensate, boiler feedwater, RO feedwater) or in the combustion chamber (air preheat). However, economizers can be used to recover and supply heat elsewhere, such as hot process water or hot utihty water, especially as used in the food processing and pulp/paper industries. Additionally, recovered flue gas waste heat can be used indirectly i.e., remote process streams can be heated locally with hot steam condensate, and then the cooled return steam condensate can be reheated in the flue gas economizer. An... 

Special process and product specifications have been set forth for companies in the chemical industry. Additionally, specific limits must be observed for pollutant or VOC (volatile organic compounds) emissions. Specific maximum allowable concentrations at workplaces must not be exceeded. Both the transport of chemicals and the recycling or disposal of chemical wastes are subject to particular requirements. Periodic hazard assessments - which in Germany, for example, are mandatory according to the Ordinance on Industrial Safety and Health (Betriebssicherheitsverordnung, BetrSichV) - are a must requirement in the chemical industry. To achieve a Continuous Improvement Process, product and process requirements must be identified, evaluated and monitored on a regular basis.

Petroleum and Petrochemical Processes. I he first large-scale application of extraction was ihe removal of aromatics From kerosene to improve its burning properties. Solvent extraction is also extensively used to meet ihe growing demand for the high purity aromatics such as benzene, toluene, and xylene (BTXl as feedstocks for the petrochemical industry. Additionally, Ihe separation of aromatics from aliphaties is one of the largesi applications of solvent extraclion. 

The overview in Table 1 holds, in principle, for any type of chemical industry. Additionally, different types of chemical industries may have different focuses, depending on their starting position and on their business requirements. Knowledge of the perspectives helps in determining the main cost drivers from the fist given in Table 1 and helps therefore in finding the starting points for process intensification studies. Table 2 presents an overview of some of the main types of chemical industries and the specific demands they posed on process intensification when applied in these industries. A distinction can thus be made between ... 

The technology and Internet bubble passed by the chemical industry and other traditional industries. Additionally, we have demonstrated above that capital markets pay less attention to short-term earnings than many assume. But how, then, does the capital market value the chemical industry ...

Additives A natural or synthetic material, other than the basic raw ingredients, used in the production of a final product. For example, additives are produced by the chemicals industry to enhance the usability of metals, coatings and other chemicals. In the food industry, additives may be used to enhance flavor, appearance or shelf life. In the petrochemicals industry, many additives are marketed to improve the performance of fuels and lubricants.

Though the data given in Table 14.2 are for Ceramicrete matrix composites, similar properties in other CBPC matrix composites are possible with different extenders. Therefore, overall CBPC matrix composites are versatile materials and have the potential for varied applications as structural and nuclear materials, as well as civil engineering applications in general. In this chapter, we discuss some common CBPC matrix composites and their applications in the construction industry. Additional applications are presented in subsequent chapters.
