Resent technolgy in chemical engineering

A distinctive characteristic of the American chemical processing scene even in its earliest years was the continuous pressure toward the exploitation of larger size, and the alacrity with which American firms moved in that direction. Nor is chemical engineering reducible to applied chemistry. This is a critical and badly neglected consideration, because the chemical sector has developed a unique set of specialist firms and organizations which have, in turn, played a major role in the innovation process. June 21, Ranked at the top for the eighth straight year, the Institute also places first in 11 of 48 disciplines. Unfortunately, it is an aspect of the innovation process that has been badly neglected. The work and decision making of the chemical engineer is inherently economic as much as it is engineering, since it involves the explicit consideration of innumerable tradeoffs in determining optimal design. Historically, success in the commercialization of new technologies in this sector has turned upon the ability to make the transition from small scale, batch production to large scale, continuous processing plants. Thus, a critical decision is to determine when it becomes worthwhile to commit to an investment that will replace the existing technology with the newest technology. Specialized engineering firms SEFs came to play a critical role in the chemicals sector during the years following the Second World War.

Scale factors have been important not just at the level of the individual plant and its optimal output, compared to the size of the available market. As the industry shifted to petroleum feedstocks in the interwar years and mastered the problems of large-scale, continuous process operations, the optimal size of plant often grew to exceed the market requirements of even the largest of western European countries.

But it should now be apparent that it is a serious mistake to visualize the competitive process as if it were entirely a matter of squeezing out, as rapidly as possible, the cost reductions offered by such existing learning curves.

In fact, larger plants typically incorporate a number of technological improvements, based upon the wealth of experience and insight into better plant design, that could be accumulated only through prolonged exposure to the problems involved in the operation of somewhat smaller plants.

Such production is not a matter of simply scaling up the tubes and retorts in which a new product was originally developed.

August 2, MIT researchers use a new machine learning technique to rapidly evaluate new transition metal compounds to identify those that can perform specialized functions.

The overwhelming emphasis that has been placed, in recent years, on moving down the learning curve of an existing, unchanging plant [category 2 ], fails to take account of the steady flow of incremental improvements in plant design [category 3 ] that, at some point, makes it economically attractive to introduce new facilities incorporating these later improvements.
