Foaming Effect on Random Packing Performance
نویسندگان
چکیده
The effect of foaming on the performance of 16 mm Pall rings was determined in a 0.15 m distillation column with a ‘bed depth of 1.23 m. The tests were conducted with the methanol/water system at 1.0 bar pressure. A controllable foaming inside the packed bed was generated successfully with the addition of the surfactant, Triton X-100, to the reflux stream. The performance of the packing with and without foaming was determined and compared. It was found that foaming reduces the mass transfer efficiency by about 20 percent, and lowers the capacity by approximately 30 percent. The results also show significant increase of the bed pressure drop caused by foaming.

Wall Effect in 3D Simulation Of Same Sized Particles Packing
In this paper, the effects of container size on the porosity of random loose packing of mono size particles have been investigated using an Event Dynamics (ED) based model. Simultaneous effects of square container walls on particles packing and their order are also investigated. Our simulation results indicate higher container size will increase the total packing factor and high density regions...

In this paper, the effects of two different Particle Size Distributions (PSD) on packingbehavior of ideal rigid spherical nanoparticles using a novel packing model based on parallelalgorithms have been reported. A mersenne twister algorithm was used to generate pseudorandomnumbers for the particles initial coordinates. Also, for this purpose a nanosized tetragonal confinedcontainer with a squar...

Formaldehyde is a dangerous compound that must eliminate from contaminated air. Different methods exist for removal of pollutants from the air that among them, the biological processes attracted a great deal of attention. Removal of formaldehyde from the contaminated air was investigated in three laboratory-scale biofilters packed with different materials (a mixture of compost and woodchips, th...

Best t is the best known algorithm for on line bin packing in the sense that no algorithm is known to behave better both in the worst case and in the average uniform case In practice Best t appears to perform within a few percent of optimal In this paper we study the expected performance ratio taking the worst case multiset of items L and assuming that the elements of L are inserted in random o...
متن کاملHydrodynamics of Foaming Systems in Packed Towers
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...
