Title: Fong-Cheng Su: Innovator in Ethanol Production
Introduction
Fong-Cheng Su is a notable inventor based in Chiayi, Taiwan. He has made significant contributions to the field of ethanol production, particularly through his innovative processes that enhance energy efficiency. With a total of 2 patents, Su's work is recognized for its potential impact on sustainable energy solutions.
Latest Patents
One of Su's latest patents is a low-energy extractive distillation process for the dehydration of aqueous ethanol. This energy-efficient process utilizes an extractive distillation column (EDC) that operates under no or greatly reduced liquid reflux conditions. The EDC can be integrated into a comprehensive system for producing anhydrous ethanol, which is essential for gasoline blending from fermentation broth. By employing a high-boiling extractive distillation solvent, the process ensures that no solvent is entrained by the vapor phase to the EDC overhead stream, even under minimal liquid reflux conditions. Furthermore, the energy requirements and operational severity of the EDC can be optimized by limiting ethanol recovery within the system. In this design, the ethanol remaining in the aqueous stream from the EDC can be recovered in a post-distillation column or recycled to a front-end pre-distillation column, where ethanol recovery is facilitated by the favorable vapor-liquid equilibrium curve for ethanol and water.
