Product design solution formulations

In principle, problems related to chemical product design can be formulated and solved in many different ways. The objective here is to highlight some of those that have also been applied in the various product design case studies reported in chapters 2-15 of this book. These solution approaches may be classified under the following types ... 

However, the systematic identification of problem solutions should be superior to a random identification of solutions, either because better solutions can be identified or because acceptable solutions can be identified sooner or with less resomce. So while it is unrealistic to eliminate all experimentation, it would be desirable to minimize experimentation through the introduction of a systematic consideration of product formulations prior to experimentation. From this perspective, the object of product design is to specify a small set of formulations likely to meet the product requirements, and which can be confirmed or refined through experimentation. Thus, chemical product design and engineering should be viewed as a phase of chemical product development that should precede a more focused experimental program. 

EPM is preferred for dynamic applications because its age resistance retains initial product design over time and environmental expo-sure.i2 ePDM is preferred for its high resilience.12 ePM is resistant to acids, bases (alkalis), and hot detergent solution. EPM and EPDM are resistant to salt solutions, oxygenated solvents, and synthetic hydraulic fluids. 2 Properties are determined by the composition of the base compound. A typical formulation includes Vistalon EP(D)M, carbon black, process oil, zinc oxide, stearic acid, and sulfur. 12... 

Because irrigations are used in or on body areas that are usually sterile or have a low degree of contaminatiOTi, there are strict requirements for their production and quality control. In this chapter the use, the design of formulation and preparation method as well as the on site preparation of irrigations will be discussed. With regard to solutions for various types of dialysis, the use of concentrates, the water quality and the requirements for bacterial endotoxins are fully discussed. 

The Hercules viscometer was originally designed for paper and paperboard coatings, but its use has been extended to paints, adhesives, mineral slurries, emulsions, and starch solutions. The iastmment, noted for being robust and rehable, is particularly well suited for quaUty control and product formulation. It is capable of measuting viscosity over a moderate range 1-10 mPa-s) up to high shear rates (115,000 ). A more recent model is the... 

In practice, every chemical reaction carried out on a commercial scale involves the transfer of reactants and products of reaction, and the absorption or evolution of heat. Physical design of the reactor depends on the required structure and dimensions of the reactor, which must take into account the temperature and pressure distribution and the rate of chemical reaction. In this chapter, after describing the methods of formulating optimization problems for reactors and the tools for their solution, we will illustrate the techniques involved for several different processes.
