This paper present a research work on the modeling of a gas absorption packed column with the aim formulating a mathematical model and simulation of the model using a computer software to obtain the rate of absorption and the amount of absorbed carbon dioxide CO2 into dilute sodium hydroxide NaOH. Arm field gas absorption column titration techniques were used for the analysis. The total concent...

The column is the main component for chromatographic separation. Nowadays, monolithic columns are graining more popularity in field of separation media liquid chromatography. monolith possess great potential as compared to conventional packed terms preparing complex mixtures. These provide various properties like higher permeability, high-efficiency fast separations, high flow rate with lower b...

By introducing sequentially connected two packed-capillary columns, a wide range of volatile compounds were successfully separated in gas chromatography. The hyphenation of two packed-capillary columns of 1.0 mm i.d. was accomplished using a conventional 6-port valve, where the temperature of each column was individually controlled in the respective column ovens. These columns were prepared w...

Foaming can be a serious problem in the process industry. For packed columns foaming is often reported for treatments of sour gases with alkaline solutions (e.g. amine scrubbing), but also for distillation and extractive distillation. Existing hydrodynamic prediction methods for pressure drop and flood points, but also for mass transfer efficiencies, do not consider foaminess. To build an exper...

INTRODUCTION In Japan, Pilot Plant of the HIDiC was built in 2005. It was commercial base scale and already achieved the consecutive distillation for 1000 hours. The energy consumption of the pilot HIDiC was only about 70% of that of a conventional distillation column. The HIDiC can lower reboiler and condenser load by heat exchange between rectifying section and stripping section. Therefore, i...

The pressure gradient and the static and the dynamic hold-up have been measured for a system consisting ofa Fluid Cracking Catalyst (FCC) of 30-150 x 10m6 m diameter, trickling over a packed bed and with a gas streaming in countercurrent flow. The experiments were carried out at ambient conditions using a glass column of 25 x 10 ~’ m diameter. The packing material consisted of 8 x 8 x 3 mm cera...
