Abstract

Proper distillation of spirits is key in maximizing resource value and producing a consumable liquid. A local brewery owner is considering entering the distilling market, and he requested information regarding a small-scale continuous column. This project used CHEMCAD to determine an operating design for continuous distillation of ethanol at a few different feed compositions. Since this model was limited to CHEMCAD, it had to build off of previous research and engineering parameters without an experimental verification. The project determined that an eight stage distillation column produced 40-58% ethanol product when the feed ranged from 7.5-12% ethanol. Eight stages produced even temperature profile for 170-180°F preheated ethanol feed entering on stage four and product extracted on stage three. The columns approximate height was four feet with a six-inch diameter. The column produced approximately 13-16% product for the given feed. The feed rate was approximately 42.5 gallons per hour. Heat integration was used to preheat the feed and condense the ethanol product. This reduced the heating exchanging utility requirement and the reboiler duty.
