Newsflash: Fuel cell technology
H-61 73 Fractional Distillation System The Model H-6173 makes educational and industrial experimentation possible in a virtually limitless range—from simple steady-state binary separations to highly sophisticated process dynamics research including column hydraulics and packing materials. Even bench-scale pilot production runs are feasible with appropriate modifications.
Major components of Model H-6173 are:
· Ten-gallon feed reservoir · Feed pump · Feed preheater · Liquid-level and overheat controlled boiler · Plate-type and packed-type columns · Glass-walled, water-cooled, shell-and-tube type condenser providing 1-1/2 ft2 of tube surface · Glass-walled distillate reservoir · Reflux pump · Reflux preheater · Coolant rotameter · Boiler, feed & reflux preheater temperature controls · Twelve Chromel-Alumel thermocouples with thermocouple selection switch · Pump heater & main power ON-OFF switches · Voltmeter and Ammeter · 72-inch manometer · Necessary valves · Quick-couple flexible hoses · Operating Manual with experiments Application Because of its compact size, relatively large capacity boiler, relatively large condensing tube surface and versatile rapidly-manipulable feed and measurement hardware, this system possesses considerably more flexibility than conventional laboratory fractional distillation equipment. Changes in operating conditions are quickly effected and column response is rapid. Students, teachers and industrial researchers are able to collect more pertinent data in a shorter time than with conventional equipment and carry exploration into distillation phenomena and processes further and at a lower cost. The effects of vaporization, condensation and liquid-vapor mixing—relative to the separation of volatile liquid systems by the application of heat—are observed and measured under the dynamic conditions of column operation. The Model H-6173 is mounted on casters and requires only water and electrical connections for operation. Because the unit has very rapid response and glass column walls, it is also used effectively in lecture demonstrations. The unit is designed for closed-loop operation with feed and product streams cycled through a common reservoir tank. However, it can be arranged to effectively separate a feedstream with separate distillate and bottoms product. Both in appearance and in operation, thecolumns are faithful replications of commercial columns. The unit does provide means for experimental external manipulation of certain internals such as the heights of the weirs and downcomers used in the plate-type column. Means are also provided for introducing feed and reflux streams at any of several pertinent locations for: obtaining liquid and vapor samples at critical locations, picking up critical temperatures and pressures, and measuring feed and reflux flows and distillation rates. Feed and reflux streams are continuously variable from zero to total. Experiment Capabilities Model H-6173 will accept a wide variety of liquid systems. The unit is physically versatile and readily modifiable for open loop or cascade type processes. These design qualities make experimental capabilities virtually limitless, even though it is not designed for cryogenic or high-pressure fractionations.
