Summary Problem

If the system performs reformulation in addition to producing initial formulations, then the user can enter the test results that have been performed on the product. Formulogic will then determine what kinds of problems with the formulation are indicated by the test results. The user can agree with the system s analysis of the problems or modify them as he or she sees fit. It uses the problem summary to make recommendations about what ingredients need to be added or what quantities need to be altered, and again the user can override the recommendations if he or she wishes. Once the user is happy with the recommendations. Formulogic will produce a modified formulation that meets the new requirements.

All calculations were performed using the Geocrack2D finite element code, which was developed to solve coupled structure / fluid / thermal problems. Summary and basic equations of the code are given in Swenson et al. (1995). A simulation consists of arbitrarily shaped rock blocks with linear / non-linear contact and discrete fluid paths between the blocks. Heat transfer occurs by conduction in the rock blocks and conduction and transport in the fluid.

In summary, the bad features of partial combustion processes are the cost of oxygen and the dilution of the cracked gases with combustion products. Flame stability is always a potential problem. These features are more than offset by the inherent simplicity of the operation, which is the reason that partial combustion is the predominant process for manufacturing acetylene from hydrocarbons. 

To complement the discussion of problems and prior pubHcation in the background of the invention, N, the inventor may generally provide a summary of the invention disclosed in the instant patent. The summary of the invention, O, should provide an explanation of the invention in the broadest and simplest terms and should also discuss how the invention disclosed in the patent solves problems remaining in prior work in this area of technology. 

There are two problems in the manufacture of PS removal of the heat of polymeriza tion (ca 700 kj /kg (300 Btu/lb)) of styrene polymerized and the simultaneous handling of a partially converted polymer symp with a viscosity of ca 10 mPa(=cP). The latter problem strongly aggravates the former. A wide variety of solutions to these problems have been reported for the four mechanisms described earlier, ie, free radical, anionic, cationic, and Ziegler, several processes can be used. Table 6 summarizes the processes which have been used to implement each mechanism for Hquid-phase systems. Free-radical polymerization of styrenic systems, primarily in solution, is of principal commercial interest. Details of suspension processes, which are declining in importance, are available (208,209), as are descriptions of emulsion processes (210) and summaries of the historical development of styrene polymerization processes (208,211,212).
