Abstract:

Sieve tray becomes a popular contacting device in distillation process because of its relative simplicity and low cost. There is one way to improve the contact performance, especially mass transfer by modifying the sieve tray into packed sieve tray. This study was aimed to investigate the effect of adding packing in each tray to ethanol content on ethanol purification. This research was conducted via experiment and simulation approaches. The experiment used packed sieve tray that contained 3 cm and 5 cm bed of steel wool with 16 trays in the column, with operating pressure about 760 mmHg and performed in batch condition. The simulation used a reduced rated base model with some modifications for operation in the packed sieve tray column. It was found that the use of packed sieve tray gave better distillate in the batch distillation process than the use of sieve tray. The packed sieve tray raised distillate content about 8.89% when using 3 cm of packing and 23.31% when using 5 cm of packing when it was compared with sieve tray. The use of packed sieve tray could increase the mass transfer and reduce bubble diameter in the batch distillation process.

Abstract:

For the separation process in liquid-liquid mixture such as ethanol-water mixture, a sieve tray distillation columnis an alternatif for affordable process and maintenance. However to date, this sieve tray system is still currentlyhaving a lower Murphee efficiency and smaller interfacial area, as compared to other tray system, that is, either abubble cap or valve tray. Therefore it is of important to optimize the performance of sieve tray distillation bymeans of adding the wire mesh packing on that tray, as being the aim of the present study. This study isconducted by using a batch sieve tray distillation system, where the wire mesh packing is added on the third traythat is calculated from the top of the column, to avoid flooding inside the column. Here the resulting fermentedmolasses of containing a 10% volume of ethanol is used as a mixture distillation feed. The height of the wiremesh packing being studied is varied as 5 cm, 3 cm, and 2 cm. Our results showed that the Murphee efficiencyobtained by the variation of the packing height of 5 cm, 3 cm, 2 cm and without packing were 73.5%, 66.27%,56.86%, and 46.7% respectively, and were increased by subsequent level of the packing height. Thecorresponding hydrodynamic properties of this appended packing sieve tray distillation by means of theinterfacial area were 11.88 cm2/cm3, 0.48 cm2/cm3, and 0.32 cm2/cm3, while its pressure drop measured from thewater manometer height were 38.33 cm H2O/m, 30 cm H2O/m, 10 cm H2O/m for the packing height of 5 cm, 3cm, 2 cm height, respectively. The increasing of the performance of appended packing sieve tray distillation bymeans of the Murphee efficiency is explained by the increasing of the interfacial area for vapour-liquid than thetray itself. This preliminary study is expected to be a pioneer study of strategy to increase the performance ofconventional sieve tray distillation that is known as a kind of affordable distillation process.

Abstract:

Two subsequent separation processes are required to produce absolute ethanol (at least purity of 99.5% v/v),namely the distillation and adsorption processes. Thus, it is important to find the optimum operation conditionfor those following processes. The aims of the present study are to optimize the feed plate of distillation and thetemperature of feed adsorbent. This study is conducted using a continuous sieve tray distillation system with thenumber of 16 trays, the length-diameter ratio of 80.64, the reflux ratio of 3.5, and the feed with ethanol contentof 10 % v/v ethanol, which is produced via the fermentation process of molasses. To conduct the first aim of thisstudy, the feed enters the distillation column with several of variable feed plate, i.e. 12, 13, 14, and 15. This feedplate location is calculated from the top of the column. On the other hand, the second aim of this study, isconducted using the subsequent combination of distillation and adsorbent columns, where the distillate (purity ofethanol around 95% v/v) from the distillation column is then flowed into the adsorbent column with various feedadsorbent temperature, i.e. 80 °C, 90 °C, 100 °C, and 110 °C, to be purified as an absolute ethanol. Here theadsorbent column is designed as a fix bed adsorption column with a molecular sieve of 3A (zeolite) is used as anadsorbent for that purification process. Our results showed that the optimum feed plate is 14, because at thisplate the ethanol distillate has the highest content among those various variables. Meanwhile, the optimumtemperature of feed adsorbent is 90° C, which requires the least energy for the distillation - adsorption process,i.e. at 18691 kJ/kg absolute ethanol. This primary study is expected to be an alternative way to optimize theoperating condition of the sieve tray distillation-molecular sieve adsorption system by means of acquiring aminimum energy involving in the process to achieve the highest purity of ethanol.

Abstract:

The flow-guided sieve-valve tray(FGS-VT)with high efficiency was designed to overcome the shortcoming of low operating flexibility of the flow-guided sieve tray. Its dimensions and geometry, as well as structure characteristics, were presented. The hydrodynamics and mass transfer performance, including dry-plate pressure drop, wet plate-pressure drop, weeping, entrainment and tray efficiency, of two types of FGS-VTs (FGS-VTs with 14 and 8 valves, respectively) and one flow-guided sieve tray were tested in an air-water-oxygen cold model experiment with a 0.6 m diameter plexiglass column. The results demonstrate that FGS-VT with 14 valves works better than FGS-VT with 8 valves, and in comparison with the flow-guided sieve tray, the flow-guided sieve-valve tray with 14 valves has higher tray efficiency, bigger operating flexibility, and lower wet-plate pressure drop (when all the valves are opened fully).Additionally, two typical applications to separate the mixture with high viscosity, solid, powder, easy-to-foam or easy self-polymerization components proved the unique advantages of FGS-VT.
