Abstract
A microcomputer-controlled digital valve system was developed to control the temperature, and hence the quality, of ethanol-water vapors leaving the product column of a small-scale distillation system. The temperature was controlled by regulating the water flow through an internal reflux coil. The temperature of the product vapor was controlled within plus or minus 0. 3 degree C. The temperature sensing devices permitted an overall temperature control accuracy of plus or minus 0. 5 degree C. A temperature monitoring routine was developed to read and display system temperatures, and a storage routine kept a record of temperatures and reflux condenser water flowrates.
