Gas liquid contact in stripping column

To get from (1) to (2), you can use the formula for the sum of a geometric series:S = x[Ain]/(1-s)S^{n+1} = x[Ain]*s^n/(1-s)S - S^{n+1} = (x[Ain] - x[Aout])*s^n/(1-s)1 - S^{n+1} = (1 - s^(n+1))Putting it all together, we get:(x[Ain] - x[Aout])*s^n/(1-s) = (1 - s^(n+1))Divide both sides by (1 - s) and we get:(x[Ain]

[itex]\frac{x[Ain]-x[Aout][/SUB][/SUB]}{x[Ain]-x[out][/SUB][/SUB]}[/itex]=[itex]\frac{\sum s^{K}-1}{\sum s^K}[/itex] (1)

for k = 0 to n

Final result:

[itex]\frac{x[Ain]-x[Aout][/SUB][/SUB]}{x[Ain]-x[/SUB][/SUB]}[/itex] = [itex]\frac{{S-S^{n+1}}}{1-S^{n+1}}[/itex]

(2)

Does anyone know how to get from (1) to (2).

Welcome to PF!

Hi RAfAEL_SP! Welcome to PF! :smile:

(use _ not SUB in latex, and use tex rather than itex for fractions that ou don;t want to be too tiny! :wink:)

Does anyone know how to get from (1) to (2).

I think you mean [tex]\frac{\sum s^{K-1}}{\sum s^K}[/tex]
Then eg the denominator is (∑sK)/(1 - S) :wink:

The exponent is just k
 

1. What is gas liquid contact in a stripping column?

Gas liquid contact refers to the process of bringing a gas (such as air or steam) into contact with a liquid (usually a solvent) in a stripping column. This allows for the transfer of volatile components from the liquid phase to the gas phase, resulting in a separation of the components.

2. How does gas liquid contact occur in a stripping column?

Gas liquid contact occurs in a stripping column through a combination of physical processes such as diffusion, evaporation, and condensation. The gas and liquid streams are brought into contact through a series of trays or packing material, allowing for the transfer of volatile components between the two phases.

3. What factors affect gas liquid contact in a stripping column?

Several factors can affect gas liquid contact in a stripping column, including the type and flow rate of the gas and liquid, the design and efficiency of the column, and the properties of the components being separated (e.g. volatility, solubility, etc.). Other factors such as temperature and pressure can also play a role in the efficiency of gas liquid contact.

4. Why is gas liquid contact important in a stripping column?

Gas liquid contact is important in a stripping column because it allows for the separation of volatile components from a liquid stream. This is a crucial step in many industrial processes, as it allows for the purification or concentration of certain components in the liquid phase. Gas liquid contact also helps to increase the overall efficiency of the stripping column.

5. How can the efficiency of gas liquid contact be improved in a stripping column?

The efficiency of gas liquid contact in a stripping column can be improved through various methods, including optimizing the design and operation of the column, using efficient packing materials, and controlling the temperature and pressure within the column. Additionally, proper maintenance and regular cleaning of the column can also help to improve gas liquid contact and overall performance.
