Analogue Computer for Multicomponent Fractionation Calculations

There appears to exist in the oil industry a definite use for a computing machine which may be employed to shorten the multi-component fractionation plate-to-plate calculations. A machine believed to be of satisfactory accuracy and reliability has been designed and is in operation. It is estimated that it reduces the computing man hours to about ten per cent of that of the former procedures. The machine can be employed not only on the design of new equipment, but also on the study of possible design and feed variations which might be made in existing fractionation columns.
