Complete late model solvent recovery system at 60% (weak feed) increasing the solvent to 85% (262 gpm of product) Isopropanol This process was designed to efficiently turn down to 65 GPM and steam to perform the separation It also includes a complement of coolers, heaters, condensers and pumps This complete process unit is a turnkey, and stand-alone operation that includes all piping, field instrumentation, pumps, structural steel, and other accessories Weak Isopropanol or other solvents, from storage (pretreated with anti-foaming agents) is preheated and fed to the column The feed rate to the column can efficiently fluctuate between 300 -65 gpm depending on the plant needs. High pressure steam is the driver for the distillation. Overheads are condensed in an air fin heat exchanger, and the overhead product returns to a storage tank for re-use, with a slip stream consumed as reflux The bottoms product are mainly water which is used to pre heat the feed, then sent to waste water treatment. Major Equipment is as follows: Column: 304 SS tray column manufactured by Hebeler. Rated for75/FV psi at 450 degrees, the unit is skirt mounted and 72” diameter x 85’ overall height.
