What is advantage of packed column?
no
What is loading point in packed column?
The point in which the droplets of liquid (solvent) are carried up with the gas in packed column. This hapens if the solvent flow is fixed & the gas flow is icreased.
Is packed fractionating column more efficient with glass beads?
and why?
Why the pressure drop is low in packed column?
air reduction
What was the poorest absorber of water is?
The poorest absorber of water is a material with low porosity and high density, such as metals like aluminum or steel. These materials have tightly packed atoms that do not allow water molecules to penetrate easily.
What is void volume in chromatography?
bed volume= pie*r square*h where, pie=3.14 r=radius of column h=height of column it is the total volume of column packed with the gel.
What problems may arise in the use from a poorly packed liquid chromatography column?
The effect of packing a chromatographic column unevenly will cause the flow to be uneven down the column and lead to poor separation.
What is the efficiency of packed columns in gas chromatography?
It is around 4000-6000 plates for a 2 meter column.
Difference between tray and packed columns?
Packed column consist of porous substance as a packing in the column which provides contact between the fluids used,while different types of trays are used depending on the ease of separation instead of a packing in a usual tray column.
What has the author Gary L Hundley written?
Gary L. Hundley has written: 'Performance of a packed distillation column with induction heated packing' -- subject(s): Distillation apparatus, Packed towers
What does flooding velocity in packed column means?
Flooding velocity in a packed column refers to the minimum gas or liquid velocity at which the column becomes completely filled or "flooded" with the fluid, preventing effective mass transfer. At this point, the flow regime transitions from a more efficient operation to a less efficient one, often leading to reduced separation performance. Understanding flooding velocity is crucial for optimizing the design and operation of packed columns in processes like distillation, absorption, and chemical reactions.
What are the different methods of preserving food?
