Patent ID: 8404109

Claim:
A computer readable program storage device encoded with instructions that, when executed by a computer, perform a method, the method comprising: (i) storing an initial solids concentration of an aqueous sucrose solution (solids i ), an initial bed volume (BV i ) of a sucrose inversion resin system, a minimum target inversion percentage (invert% min ), a maximum target inversion percentage (invert% max ), a target maximum hydroxymethylfuran (HMF) concentration (HMF max ), a minimum target pH (pH min ), or a maximum target pH (pH max ); (ii) observing an instantaneous inversion percentage (invert% inst ), an instantaneous HMF concentration (HMF inst ), and an instantaneous pH (pH inst ) of an inverted sucrose solution produced by contacting the sucrose inversion resin system with the aqueous sucrose solution under conditions of aqueous solution flow rate in BV i /hr (rate p ) and aqueous solution temperature in ° C. (temperature p ); and, if invert% inst <invert% min , invert% inst >invert% max , HMF inst >HMF max , pH inst <pH min , or pH inst >pH max ; (iii) changing the aqueous solution flow rate, the aqueous solution temperature, or both of a second portion of the aqueous sucrose solution such that invert% min ≦invert% product ≦invert% max , HMF product ≦HMF max , or pH min ≦pH product ≦pH max .
