Sarex 1
Sarex 1 : (1) Saccharide Extraction. A version of the Sorbex process, for separating fructose from mixtures of fructose and glucose. The usual feed is corn syrup. The adsorbent is either a proprietary zeolite or an ion-exchange resin. Unlike all the other Sorbex processes, the solvent is water. The process depends on the tendency of calcium and magnesium ions to complex with fructose. The patents describe several methods for minimizing the dissolution of silica from the zeolite. The process is intended for use with a glucose isomerization unit, so that the sole product from corn syrup is fructose. Invented by UOP in 1976; by 1990, five plants had been licensed. (2) SAREX. A process for recovering oil from wash liquors. Developed by Separation & Recovery Systems
