PLANT ADAPTATION
After-Vacuum
Distillation, Propane Fractionation, and Deasphalting Units
Most of the available information on process design has to do with the design of new plants and equipment. A good part of design work in the chemical industry, however, i s concerned with adaptation or expansion of existing plants. The design situation becomes more complex in this type of work; factors become fixed which ordinarily are variables, and points of emphasis must b e shifted. The problem of deciding whether to adapt or expand rather than to build a new plant is also a complex one. In many instances the particular situation of the company involved is the main factor; in others, broad forces such as wartime conditions or changes in the general tax structure play a part. The purpose of this symposium, which was organized b y the ACS Division of Industrial and Engineering Chemistry, i s to evaluate these factors and to present the opportunities and problems in making plants perform in ways for which they were not designed.

Because of the great general interest in the subject matter presented here a condensation of this group of articles was published in the August 30, 1954, issue of Chemical and Engineering News. W e present here the detailed versions with the hope that some of the more general audience of C&€N may have been sufficiently stimulated b y the condensation to be interested in the whole story and with the assured conviction that those directly concerned with plani adaptation problems will find the complete articles well worth their careful study.-THE EDITORS
