In what situation would you use fractional distillation over simple distillation?
You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process
Why molar flow for distillate and bottom in distillation must be same?
I would not say that the molar flow of those two streams need to be the same but rather their sum should equal the input into the distillation column. Moles of A in = Moles of A Distillate + Moles of A Bottom If you think about it, it makes very little sense that both streams should be equal because that would indicate you are doing a very poor separation! You ideally want to concentrate one product in either stream as best you can, while the other products get separated somewhere else in the column. If A is very volatile relative to other inputs, one would expect that Moles of A Distillate >> Moles of A Bottoms Normally you should avoid molar balances as moles are not usually conserved in many processes; however, distillation is simply a separation, so therefore a molar balance is safe to use but verify your assumptions!
How do you calulate the feed plate of a distillation column?
For a binary set of components you calculate the feed tray using the McCabe Thiele method. For more complex systems you would need to use a process simulator and perform a sensitivity analysis to determine the optimum feed tray.
What is a column cap plate and what is its purpose?
column cap plates are commonly used to secure the column head to a beam using bolts driven through the plate and beam bottom flange. The plate is welded to the column head usually with fillet welds although fully penetrating butt welds would be better since this would provide the greatest restraint to bending and shear (transverse/longitudinal) at the plate/column head junction.
What is the formula for calculating how much concrete you need in a column?
You need the dimensions of the column to calculate the volume. The formula would need to include the three dimensions in some form.
Which column would be used to separate components in a chemical mixture by boiling point?
A distillation column; see the link below for some models.
What technique would separate a solution with many components?
Fractional distillation is only useful if the components are liquid, and the separation is based on boiling point. Another, more applicable method would be chromatography, either thin layer, paper, or column.
If the rate of the distillation through a packed column is too rapidflooding occursWhat effect would flooding have on the distillation?
If the rate of the distillation through column is too rapid flooding occurs will effect on distillation rate causing low crude column flush zone vaporization that causes low internal reflux rate between GO and GO product and the light materials does not vaporize and it will effect on fractionation ability. Those effects on the specification of the distillation. So effective on crude temp. it will be dropping then crude hydraulic limitation occurred and making the problem worse. so in the top of column boiling film will cause,
Would you that mixing gases is a reversible change?
It isn't easily reversible but, it is reversible. You can use a molecular sieve or a distillation column to separate them.
Fractional distillation and the impact on the environment?
Fractional distillation it is separating mixtures via their boiling points. Fractional distillation is done by adding some sort of material into the column that the vapor travels before being cooled and condensed while. Since the fractional distillation means the separation of a mixture into different componenets.Suppose the raw material entering into the distillation column contains many fraction(for example,if a crude oil is entering,it contains gases,gasoline,kerosene etc). if a distillation is done for such a material.this will be the fractional distillation.Because in a distillation column you will separate different components present in the crude Check the related question below to know more.
What are three way that mixtures can separated?
Three ways would be Liquid liquid - distillation (separation based on boiling points) Column chromatography separates solids dissolved in eluent based on polarity Filtration (washing with a solvent that dissolves one compound and not another)
How would you show the value of 100 on a stem and leaf plot?
You would add another column
What is conventional distillation?
This is just a guess, but I would assume the term is to distinguish it from fractional distillation.
What would happen to the cell reference if you were to copy the formula equals A245 one column to the right?
It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245It would change the column reference by one column and become:=B245
Is it true the taller you are the longer your arms will be?
describe how? the taller the person is, the taller the arms would be
When you insert a column where does it automatically go?
The column will go where the currently selected column is, pushing all columns to the right. So if column D was selected and you inserted a column, column D would become column E and the inserted column would now be column D.The column will go where the currently selected column is, pushing all columns to the right.

What is a leftmost column?
It is the first column in a table on the left. In a spreadsheet it would be column A. In Access it would the column for the first field. In a table in Word, it would be the first column on the left.
