Abstract
A process for separating naphtha feed stream and recovering heat from at least one stream from a column by heating other columns. Preferably, both an overhead stream and a bottom stream from a first column heat a second column and a third column. The pressure of the overhead stream is increased, resulting in an increased temperature of the overhead and bottoms streams. The overhead stream can be split into portions to heat other columns.
