Economics factors affecting

It would be possible to remove all of the heat by pumping cold reflux from the distillate drum to the top of the tower and thus eliminate the cost of the pumparound circuit. Where more than one sidestream is withdrawn, however, it is usually economical to withdraw part of the heat in a pumparoimd reflux system farther down the tower. The following economic factors affect the choice ... 

Fan (1989) provided a detailed historical development of three-phase fluidization systems in reactor applications. Only a brief review of the significant accomplishments and the economic factors affecting the development of three-phase reactors will be provided here. Table 1 provides the important contributions in the application of three-phase fluidization systems for the past several decades. The direct liquefaction of coal to produce liquid fuels was the first commercial reactor application of three-phase fluidization systems, with development having occurred from the mid-1920 s throughout the 1940 s. A large effort was put forth at this time in Europe for the production of liquid fuels from coal as a direct...

Several economic factors affect commercialization of mycoherbicides (54. 64). the ultimate consideration being the projected economic returns from the mycoherbicide. A pathogen that is prone to be unprofitable or unpredictable in this respect, whether due to small market size, cost of production and marketing, competition from other alternative controls, or efficacy, is unlikely to be developed or offered for sale by commercial enterprises.

Economic factors will certainly impact the future of nuclear power. Members of the University of Chicago Department of Economics and the Harris School of Public Policy participated in a detailed study of the economic factors affecting the future of nuclear power.f In the long term nuclear power can be competitive with other sources given initial financial incentives. 

Spence and Haynie ( 0) discussed two surveys by Michelson and Tourin, and Booz al. in which an attempt was made to correlate concentration of atmospheric particulate matter with the frequency of repainting. Although these surveys showed a correlation, there are many unanswered questions. The effects of other pollutants, the type of paint used, and the social and economic factors affecting painting frequency were not taken into account.

I would like to propose a framework which focuses on the chemical engineer as a person and three related aspects of his life the job, the contribution to the society, and the responsibility to the physical world (Fig. 1). First, however, I shall highlight the important social, technological and economic factors affecting the life of the chemical engineer.
